INTRODUCTION
Thank you for choosing the Mackie HR824 MK2 Studio
Monitors. We began producing the original HR824
Studio Monitors in 1997, and they quickly became the
standard by which near-field studio reference monitors
were compared for extremely flat frequency response at
a reasonable price. The HR824 MK2s have been rede-
signed with modern components for improved accuracy
and an extended low-frequency response.
•
•
The amplifiers are designed to provide maximum
acoustic output from the speakers, yet minimize
the danger of speaker damage due to overdriving.
In addition, the amplifiers’ gain and frequency re-
sponses are individually hand-trimmed to compen-
sate for typical manufacturing tolerances between
the drivers and produce a smooth frequency
response from 35 Hz to 20 kHz.
•
•
The connecting wires between the amplifier outputs
and the drivers are kept to an absolute minimum,
so the damping factor of the amplifier isn’t compro-
mised by the resistance of long speaker cables.
Investments in Excellence...
When we decided it was time to update the HR824s,
we turned to our expert loudspeaker and transducer de-
sign engineering team at EAW to determine how to make
an already excellent studio monitor even better. The
first thing they noticed was that the front baffle could
be redesigned with a rounder aluminum construction
to further reduce edge diffraction for improved imag-
ing. The volume of the cabinet was increased slightly to
improve the low-frequency response. The amplifiers have
been adjusted with all new ‘voicing’ to match the new
cabinets. However, the amplifiers’ design is fundamental-
ly the same and has a very similar characteristic to the
original model. If you are upgrading from the original
HR824s, you won’t have to relearn the sound. The MK2s
still deliver the clarity, ultra-linear frequency response,
and broad stereo imaging of the originals.
The acoustic sum of the outputs from the two driv-
ers are optimized electronically, as well as physi-
cally, so the amplitude response is unity and the
phase difference is minimal.
In short, all the complex interconnected components
in the system are designed to work in harmony with
each other to produce the best possible sound.
The Transducers...
The monitors feature an 8.75-inch high-precision, low-
distortion woofer and a 1-inch ferrofluid cooled titanium
dome tweeter on the front, and a 6-inch x 12-inch ellipti-
cal flat piston passive radiator in the back.
An elegant piano-black gloss finish emphasizes that
these studio monitors are in a class by themselves,
pleasing to the most discerning eye as well as the most
discerning ear.
The high-frequency driver is mounted on a massive,
acoustically non-resonant die-cast aluminum exponential
waveguide, which results in wide, controlled dispersion
of high-frequency sounds. The unique passive radiator
design provides tight, articulate bass response down to
35 Hz — an astounding accomplishment for a cabinet
of this size! And since the radiator is producing most of
the sound at the lowest frequencies, there is very little
distortion from the woofer because its cone movement
is minimal at those frequencies.
The result? The HR824 MK2 Studio Monitors are
extremely accurate and versatile, loaded with unique con-
trols that allow you to fine-tune the sound to match your
individual environment precisely. You’re gonna love these!
What are they? The Advantages...
The HR824 MK2 Studio Monitors are high-
resolution, two-way, bi-amplified, active moni-
tors employing a 6th-order Butterworth system
with a built-in rear-firing mass-loaded passive
radiator. Whew! There are many benefits to
integrating an active crossover, power amplifi-
ers, and drivers into a single cabinet, and we’ve
taken full advantage of these benefits in the
design of the HR824 MK2.

The crossover point is designed so that the
high- and low-frequency drivers are fed
only the frequencies they are best able to
reproduce.

1. Connect the line-level monitor signal from your mixer,
preamp, or other signal source to the SIGNAL INPUT
[1] jack on the HR824 MK2 Studio Monitor (1⁄4-inch
PHONE, XLR, or RCA).
2. Connect the supplied AC power cord to the IEC socket
[7] on the back of the monitor. Plug the other end into
an AC outlet properly configured with the correct volt-
age for your particular model.
The Cabinet...
The cabinet is made of MDF with a high-gloss piano-
black finish. Internal bracing increases the strength and
rigidity (stiffness) of the box. An open-cell adiabatic
foam material fills the inside of the box to absorb inter-
nal reflections and dampen standing waves. Mounting
hardware is installed on the bottom of the cabinet that
fits the 60.0 WB OmniMount wall-mount bracket (see
“Placement” on page 6 for more info).
3. Set the POWER MODE [6] switch on the rear panel to
the ON position. With the front panel power switch [9]
out, the power amplifier is in Standby mode.
4. Start your signal source (tape deck, CD, DAW, or
whatever), but leave the master volume control on your
mixer or preamp down.
5. Push in the power switch [9] on the front of the HR824
MK2. The power ring [10] around the switch will illumi-
nate.
6. Slowly turn up the INPUT SENSITIVITY [2] control on
the back of the monitor to its fully clockwise position
(NORMAL).
7. Adjust the master volume on your mixer to a comfort-
ably loud listening level. Enjoy the silky smooth highs
and authoritative, commanding lows of the HR824 MK2.
Then read the rest of this manual.
FR Series Power Amplifiers...
What better way to power the loudspeakers than with
our acclaimed FR Series “Fast Recovery” power amplifi-
ers. Our Fast Recovery design uses low negative feed-
back, yet allows the amplifiers to maintain low distor-
tion and stability even when driven into clipping.
The low-frequency amplifier produces up to 150 watts
continuous (350 watts peak) before clipping, while
the high-frequency amplifier produces up to 100 watts
continuous (210 watts peak).
QUICK START
AN EXTREMELY IMPORTANT NOTE
ON HR824 MK2 BASS RESPONSE
AND YOUR CONTROL ROOM.
We realize that you can’t wait to hook
up your new Mackie HR824 MK2 High
Resolution Studio Monitors and try
them out. Nevertheless, please take
the time to read this page NOW, and
the rest can wait until you’re good and ready.
Your new HR824 MK2s achieve their
best bass response in a room that’s
optimized for bass reproduction. A
Each of the HR824 MK2 cabinets has its own built-
in power amplifiers. That’s right, two amplifiers per
speaker cabinet; one for the high-frequency tweeter
and one for the low-frequency woofer. You should turn
the INPUT SENSITIVITY [2] control on the back of the
cabinet down (fully counterclockwise) before turning
on the Studio Monitors for the first time. Also be sure
to set the power switch [9] on the front panel to its
standby position (out). This will prevent you from acci-
dentally connecting a hot signal source to the monitors
and getting a rude surprise.
lot of factors can conspire to thwart
the HR824 MK2s’ extended low
frequency — including room shape, room volume and
acoustical treatment.
This is not a cop-out or an apology. It’s plain old
physics in action. Luckily we’ve armed you with some
compensating controls that you can use to optimize the
frequency response of the speakers in your particular
room. Consider the following:
The ACOUSTIC SPACE switch
must be set correctly.
There are a number of other settings you can make
on the back of the HR824 MK2, and you can look at the
graphic instructions relating to each of them on the
back of the cabinet (or wait until you read about them
later on in this manual so you really know what they
do). For now, just leave them at the factory default
settings (ACOUSTIC SPACE = WHOLE; LOW FREQ =
49Hz; HIGH FREQ = 0), except for the POWER MODE
[6] switch. Be sure it is set to the STANDBY position.
When you put your HR824 MK2s in a corner or up
against walls, their bass characteristics change. Adjust
the ACOUSTIC SPACE [3] switch setting accordingly to
avoid muddy or exaggerated low frequency response.

Feel free to experiment.
Placement
In many respects, every room is unique in terms of its
acoustics.
The HR824 MK2s were designed to be placed in a
vertical position. If you find it necessary to place the
speakers in a horizontal position (on their sides), place
them so that the woofers are toward the inside; that is,
so the woofers are closest to each other. This provides
the best low-frequency summing and overall imaging.
Even after you’ve read about how to set the HR824
MK2’s rear panel switches, try other settings to see if
your particular room environment requires different
adjustments.
The HR824 MK2s can also be wall-mounted using the
mounting hardware located on the bottom of the cabi-
net. This is designed to be used with the OmniMount
60.0 WB (Wall-to-Bottom) wall-mount bracket, which
provides a wide range of horizontal and vertical move-
ment to meet your coverage requirements. Refer to the
OmniMount website for more details.
And, even after you’ve placed your monitors where you
think they’ll sound best, try moving them around. You
might be pleasantly surprised.
Finally, keep an open mind about
improving your room’s acoustics
and bass-handling ability.

Nobody likes to buy a new set of monitor speakers
and then be told that they should spend extra bucks on
bass traps or a remodeling job. But the simple fact is,
“standard” rooms, i.e., rectangular rooms in convention-
al business or residential structures, are rarely if ever
conducive to optimal low bass reproduction without
some modifications.
A Few Words About THX™pmꢁ™
Certification
Nearly two decades ago, George Lucas turned a
passion for great sound into the world’s most accepted
and trusted solution for achieving it. The standard was
named THX (for Tomlinson Holman, who developed
the THX Sound System when he was the research and
technical director at Lucasfilm Ltd.™ in the early 80s),
and today, with hundreds of thousands of home theater
customers and more than 3000 THX Certified movie the-
aters enjoying its benefits, the THX name has become
nothing short of legendary. Simply put: when it comes
to premium sound, no other name so closely defines
‘quality’ for millions of movie-goers and home theater
enthusiasts alike.
Luckily, there are plenty of options short of building
a new control room, many of which are covered in this
manual.
Additional Tidbits of Wisdom
• When you shut down your equipment, turn off the
HR824 MK2 studio monitors first to prevent thumps
and other noises generated by any upstream equipment
from coming out the speakers. When powering up, turn
on the monitors last.
• Save the shipping box! You may need it someday, and
you don’t want to have to pay for another one.
• Save your sales receipt in a safe place.
Today, a new landscape is emerging. A landscape com-
prised of hundreds of small, professional multi-channel
facilities, whose need for differentiation, expert techni-
cal and marketing support, and a true, multi-channel
• Also record all HR824 MK2 serial numbers in the space
provided on the next page, along with where and when
you bought them.
Note: The Mackie logo can be rotated 90º so
that it is oriented correctly when placing the
speakers on their sides. Gently pull out on
the Mackie emblem, rotate it, and push it
back into place.

standard is becoming a competitive fact of life. Again,
THX has a singular solution and this time it’s called
THX pm3 Certification.
Contents
All facilities involved with mixing and/or monitoring
of multi-channel material should have the option to use
pm3. THX pm3 Certification is ideal for DVD mastering,
sweetening, and mixing; and is also perfect for facilities
doing work in broadcast, music, or multi-media applica-
tions.
HR8ꢀ4 MKꢀ THX pmꢁ Certification
When we submitted the HR824 MK2s for THX pm3
Certification, they passed on the first try with no modifi-
cations!
Anyone seeking THX Certification for their studio,
or striving to maintain THX standards, can use the
HR824 MK2s and rest assured that their facility is in
full compliance.

The HR824 MK2 expects a line-level signal at its input
connectors.
1. SIGNAL INPUTS
The location of the signal input jacks makes the con-
nectors exit down and not straight out the back of the
enclosure. This flush-mount design allows you to place
the monitor right up against the wall if desired.
• The reference sensitivity is –7.5 dBu=100 dB SPL at
one meter (39 inches) with the INPUT SENSITIVITY
control set to its NORMAL position (in other words,
wide open).
• The XLR female, TRS female (balanced), and RCA
female (unbalanced) input connectors are provided for
user convenience.
• The HR824 MK2 is designed to operate with a +4 dBu
signal when the INPUT SENSITIVITY control is in the
NORMAL position.
• Don’t connect more than one source to the jacks.
• Refer to the QUICK START section on page 4 for the
level-setting procedure.
• Unbalanced TS (tip-sleeve) lines can be accommodated
via the TRS jack. Make sure the cable terminates with
a TS plug (like a guitar plug), or if it’s a TRS plug (such
as a headphone plug), make sure the ring is tied to the
sleeve and that the plug is fully inserted into the jack.
ꢁ. ACOUSTIC SPACE
• The XLR and TRS input connectors accept balanced or
unbalanced signals. The connectors are wired as follows

This is a three-way switch that adjusts the low-fre-
quency response of the monitors to compensate for their
placement in the room. See page 5 for an overview of
the rear panel.
• The HR824 MK2s can be used with a home receiver
even if the receiver lacks a preamp output by using a
speaker-level to line-level signal attenuator. (See page
13 for more information.)
• If you place the HR824 MK2 monitors against a wall
(half space [3B]), set the ACOUSTIC SPACE switch
to the “B” position. This activates a shelving filter to
reduce the low-frequency output by 2 dB to compensate
for the half-space placement.
• If you place the monitors into the corners of your
room (quarter space [3A]), the low-frequency output
approximately doubles from what it is in half space.
Set the ACOUSTIC SPACE switch to the “A” position to
reduce the low-frequency output by 4 dB to compensate
for the quarter-space placement.
• If you use the HR824 MK2s free-standing, away from
walls and corners (whole space [3C]), set the ACOUS-
TIC SPACE switch to the “C” position (NORMAL).

Removing the low-frequency content also allows
you to raise the overall output level somewhat. Low-
frequency information requires the largest amount of
an amplifier’s output, so restricting the low-frequency
content allows raising the mid-frequency level some-
what. If your client insists on mixing LOUD, this may be
a workable strategy.

• For THX applications, use the 80Hz setting.
THX = 0 dB
• For non-THX applications where a sub-woofer isn’t en-
hancing low-frequency output use the 37Hz (NORMAL)
position.
• The LOW FREQ switch affects the low-frequency con-
tent of your mix. Remember how things work in reverse,
so removing the deep bass content on playback may
actually increase it in the final mix.
• You can use the LOW FREQ switch’s 80Hz position to
simulate a smaller loudspeaker, especially one with
limited low-frequency capability (like a certain popular
2-way nearfield monitor). You may need to do this if a
small speaker is the eventual destination of your mix,
or perhaps just to see how your mix sounds on a clock
radio.
The HIGH FREQ FILTER switch tailors the overall
high-frequency response by 2 dB beginning at 10kHz.
Leave this switch in the 0 (NORMAL) position unless:
• You want to subtly brighten or darken the sound of the
speakers.
• Perhaps you have hearing loss caused by too many
nights in front of a double Marshall stack.
• You just like to mix on the bright side or dull side.
If your mixes consistently sound dull or dark when
you listen elsewhere, this usually indicates that your
monitors are too bright, relative to your normal hearing.
A bit less high-frequency energy usually fixes this, and
you can force the mix in this direction by reducing the
high-frequency output of the monitors by using the –2 dB
position of the switch.

[9]
Start with the response modification switches in the
factory recommended settings (see Quick Start Sec-
tion). After prolonged listening, if you notice a trend in
your mixes, perhaps making some small adjustments as
suggested here will help.
• In the STANDBY position, the power amplifiers are in
Standby mode and produce no sound. Low-level circuitry
is still active, but the power consumption of the cir-
cuitry is minimal (8 watts).
• Flip the switch to the ON position and the power ampli-
fiers are live and operate normally. (The front panel
power [9] switch must also be IN.)
• When it’s in the AUTO ON position, the amplifiers turn
on and off depending on the presence or absence of an
input signal. An input signal level of –45 dBu (mini-
mum) activates the auto-on function. A silent period
greater than eight minutes activates the auto-off func-
tion. The power ring [10] on the front panel reflects the
state of the amplifiers.
It’s a real rush to mix really loud. But remember that
the resulting mix only sounds good when you play it at
least that loud. However strange it may sound, mixes
made at lower levels sound even better when played
loud; perhaps even a bit bigger than life.
Get that sound level meter out. Decide what level
you’re going to mix at and use the meter to help keep
your mixing at that level. Your ears will thank you, and
your mixes will be better for it.

• When the POWER MODE [6] switch is in the ON
position (and the front panel power switch [9] is in the
IN position), applying AC power activates the muting
circuit for about four seconds while the power supply
and internal circuitry stabilize, then the HR824 MK2
unmutes and is ready to go.
• Simple ports or ducts must have sufficient surface
area to prevent the velocity of the air within them from
exceeding 5% of the speed of sound, which keeps the
vent from becoming audible (breathing and wheezing
sounds) at high signal levels.
• This requirement for sufficient surface area creates a
design problem when using ports — finding enough
space in the enclosure for them to fit.
8. Passive Radiator
The passive radiator replaces the port found on most
speaker systems. It offers several advantages to simple
porting:
When you mount a loudspeaker in a box, there are two
things that you can do with the radiation from the rear of
the cone: use it to enhance the low-frequency performance
of the speaker system (bass reflex system) or soak it up
(acoustic suspension system).
• One primary advantage of a passive radiator is that it
can reproduce low frequencies with lower distortion
and at a higher sound pressure level (SPL) than a
simple port or duct.
• Our unique passive radiator design uses a flat dia-
phragm providing exceptional stiffness to the radiating
surface.
• The elliptical shape of the passive radiator takes up
nearly the entire surface area available on the rear of
the enclosure, allowing the passive radiator to move
more air than a port.
• A bass reflex system uses the rear radiation to extend
the low-frequency response. Most systems provide holes
(ports) in the front or back of the cabinet to release the
rear wave. Sometimes the holes have tubes (ducts) in
them. The dimensions of the holes and the volume of
the cabinet work with the characteristics of the woofer
to produce low-frequency extension. These systems are
characterized by good low-frequency performance down
to the –3 dB frequency set by the design. Below this
frequency, the frequency response falls at 24 dB/octave
or more.
The HR824 MK2 is a bass reflex 6th-order system.
Rather than use ports, the vent takes the form of a pas-
sive radiator, a mass-loaded flat piston coupled to the air
trapped within the enclosure. You can’t see the passive
radiator because it is located at the rear of the cabinet,
behind the power amplifier assembly.

FRONT PANEL DESCRIPTION
9. Power Switch
Use this switch to turn on or off the HR824 MK2 from
the front. It works with the POWER MODE [6] switch
on the rear panel in the following way:
• If the POWER MODE switch on the rear panel is set
STANDBY
ON
AUTO
ON
to STANDBY, the front panel power [9] switch has no
effect. The power [10] ring remains off.
POWER MODE
• If the POWER MODE switch is ON, the front panel
power switch turns the HR824 MK2 on or returns it to
STANDBY mode, as indicated by the power ring.
• If the POWER MODE switch is in the AUTO ON posi-
tion, the front panel power switch turns the HR824 MK2
on, even when there is no signal present. If there is no
signal after about two minutes, the auto-off function
is activated and the amplifiers go into Standby mode,
indicated when the power ring goes off.
10. Power Ring and Overload Indicator
The power ring around the power switch illuminates
when the power amplifiers are on, and turns off when
the amplifiers are in Standby mode or off.
The power ring turns red when the overload protec-
tion circuit has been triggered.
• Occasional blinking of the overload indicator means
that the loudest transients are reaching the maximum
drive capability of the amplifiers. This is okay, although
distortion may be audible.
Overload Protect
• If you see the overload indicator [10] blinking more
than just occasionally, it’s an indication that you should
reduce the signal level coming from your mixer or other
signal source.
• The blinking overload indicator means the driver
thermal overload protection has activated a compressor.
This reduces the input level to the amplifiers.
• Frequent or continuous blinking of the overload indica-
tor means that you have exceeded the maximum drive
allowed for the speakers. The amplifiers are clipping,
and the overload protection circuit has taken over, re-
ducing the input level. You should reduce the level from
your signal source until the overload indicator blinks
occasionally or not at all.
• The compressor was designed to protect the speakers
and its action is highly audible.
PROTECTION CIRCUITS
If a client insists on listening to the
monitors at a very high volume, you
may find that the overload indicator
lights frequently. Since the majority of
the power requirement in any monitor
There are a number of protection mechanisms de-
signed into the HR824 MK2 to safeguard the loudspeak-
ers from inadvertent damage.
CAUTION: The protection circuits are designed to
prevent damage to the loudspeakers under reasonable
and sensible conditions. Should you choose to ignore
the warning signs (i.e., frequent overload indications,
excessive distortion), you can still damage the speakers
in the HR824 MK2 by overdriving them. Such damage is
beyond the scope of the warranty.
are the low frequencies, selectively reducing the low
end can provide a little more headroom and volume
for the monitors. Change the LOW FREQ FILTER [4]
switch to 80Hz if necessary, to reduce the bass response.
This may allow the HR824 MK2s to play just enough
louder to satisfy the client and to eliminate most of the
amplifier clipping.

Thermal Protect
CARE AND CLEANING
All amplifiers produce heat. The HR824 MK2 is de-
signed to be efficient both electrically and thermally.
Remove the protective plastic film that encases the
cabinet.
• If for some reason the heatsinks get too hot, a thermal
switch activates, placing the HR824 MK2 into Standby
mode (indicated when the power ring [10] turns off).
• Should this happen, make sure that airflow to the rear
of the cabinet is not restricted.
Note: You may leave the protective
plastic film on the cabinet if you
wish, or you can remove all but the
side that will be in contact with the
surface it is sitting on to protect the
• When the heatsinks cool down to a safe temperature,
the switch resets and normal operation resumes.
finish. Also, you should save the protective plastic film
to reapply to the cabinet in case you need to move it to
another location (or return for servicing).
Integrated Magnetic Shielding
The piano-black finish on the HR824 MK2 cabinets is
exceedingly beautiful, yet extremely delicate. Clean the
outside of the cabinet with an optical grade non-scratch
cloth, such as you would use to clean eyeglasses, CDs, or
DVDs.
The HR824 MK2 Studio Monitor contains drivers
with large magnet structures. The drivers’ magnets are
shielded to help prevent the magnetic field from radiat-
ing out into the environment and playing havoc with
computer monitors or TV screens. Unshielded speakers
can cause distortion in both the shape and color of the
picture if placed too close to a CRT (cathode ray tube).
If you have a particularly sensitive computer monitor or
TV screen, it may be necessary to move the speakers a
few inches away.
Input Signal Wiring
You should use high-quality, shielded cable to connect
the signal source to the SIGNAL INPUT jack [1] on the
HR824 MK2.
• Foil shielded cables, such as Belden 8451, 8761, or 9501
are commonly used for studio wiring.
• Microphone cables work well.
• The better the shield, the better the immunity from
externally induced noise (like EMI and RFI). Route the
cable away from AC power cords and outlets. These are
common sources for hum in an audio signal. Wall warts
and line lumps are especially insidious hum inducers!
You can purchase quality cables from your Mackie
dealer.
• In certain home theater applications, it may be nec-
essary to connect the speaker outputs from a stereo
receiver to the inputs of the HR824 MK2s, if the receiver
doesn’t have preamp outputs or other line-level output
connections.
CAUTION: Do not attempt to con-
nect a speaker output directly to the
input of the HR824 MK2! Speaker
levels are much higher than line lev-
els and can damage the input circuitry
in the HR824 MK2.
You can, however, insert a speaker-level to line-level
signal attenuator between the receiver’s speaker output
and the HR824 MK2’s input. Your Mackie dealer may be
able to help you find one, or you can build your own.

Bad Sound
SERVICE INFO
• Is the input connector plugged completely into the
jack? If using a 1⁄4" TS or TRS plug, make sure it is
plugged all the way in.
• Is it loud and distorted? Reduce the signal level at the
mixer.
• If possible, listen to the signal source with headphones
plugged into the preamp stage. If it sounds bad there,
it’s not the monitor.
• Too much bass or not enough bass? Move around the
room and see if the bass response changes. It’s possible
your listening position coincides with a room mode
where the low frequencies either become exaggerated
or nulled. If so, try moving the monitors to a different
position, or moving your listening position.
Details concerning Warranty Service are spelled out in
the Warranty section on page 19.
If you think your monitor has a problem, please check
out the following troubleshooting tips and do your best
to confirm the problem. Visit the Support section of our
website (www.mackie.com/support) where you will find
lots of useful information such as FAQs, documentation,
and user forums. You may find the answer to the prob-
lem without having to send your monitor away.
Troubleshooting
Noise/Hum/Buzz
• Check the signal cable between the mixer and the
monitor. Make sure all connections are secure. These
problems usually produce crackling noises, hum, or
buzz.
• If connecting an unbalanced output to the HR824 MK2
balanced input, make sure the shield is connected to the
unbalanced ground of the source and to pins 1 and 3 of
the XLR (or the sleeve and ring of the TRS jack).
No Power
• Our favorite question: Is it plugged in?
• Make sure the power cord is securely seated in the IEC
socket [7] and plugged all the way into the AC outlet.
• Make sure the AC outlet is live (check with a tester or
lamp).
• Is the power [9] switch on the front panel pushed in
and the POWER MODE [6] switch on the rear panel in
the ON position?
• If a CATV cable is connected to the system, try discon-
necting it. If the hum goes away, call your cable carrier
to check for proper grounding of the cable.
• Is the power ring [10] on the front panel illuminated?
If not, make sure the AC outlet is live. If so, refer to “No
Sound” below.
• If the power ring is not illuminated, and you are certain
that the AC outlet is live, it will be necessary to have
the HR824 MK2 serviced. There are no user-serviceable
parts inside. Refer to “Repair” at the end of this section
to find out how to proceed.
• Make sure the signal cable is not routed near AC cables,
power transformers, or other EMI sources (including
wall warts and line lumps!). These sources usually
produce hum.
• Is there a light dimmer or other triac-based device on
the same AC circuit as the monitor? Dimmers cause
buzzing noises. Use an AC line filter or plug the monitor
into a different AC circuit.
• Excessive hiss is an indication of an incorrect gain set-
ting somewhere before the speaker.
No Sound
• Is the power ring [10] on the front panel illuminated? If • If possible, listen to the signal source with headphones
not, refer to “No Power” above.
plugged in. If it sounds noisy there, it’s not the monitor.
• Is the INPUT SENSITIVITY [2] control turned up?
I hear sound from the monitors after I switch
the AC power off!
• Use the front panel switch to turn the monitors on and
off, or turn off the signal going to the monitors when the
AC power is turned off.
• Is the signal source turned up? Make sure the signal level
from the mixing console (or whatever device immedi-
ately precedes the studio monitor) is high enough to
produce sound.
• If it’s a stereo pair, try switching them around. For
example, if a left output is presumed dead, switch the
left and right cords at the monitor end. If the problem
switches sides, it’s not the monitor. It could be a bad
cable, or no signal from the mixer.
