Amplifier Precautions  
Before using the power amplifier M-5000R, be sure to  
read the page above entitled Important Safety Instructions  
and this page of Amplifier Precautions.  
Installation location and space  
Speakers  
Make sure that the floor or cabinet or rack where it will be  
located is strong enough to support its weight.  
You will also need to leave enough space behind the  
M-5000R to allow room for the power cord and other  
cables for connecting system components. A minimum of  
10 cm (4") is required behind the M-5000R to allow room  
for the cables and cords without excessively bending  
them.  
Connected speakers should have an impedance of 4 ohms  
or greater.  
Ventilation  
If speakers with an impedance of less than 4 ohms are  
connected to RCA jacks, it may damage the M-5000R.  
If a speaker with an impedance of less than 6 ohms are  
connected to an XLR jack, it may damage the M-5000R.  
Read the instructions supplied with your speakers.  
Pay close attention to speaker wiring polarity. In other  
words, connect positive (+) terminals only to positive (+)  
terminals, and negative (–) terminals only to negative (–)  
terminals. If you get them the wrong way around, the  
sound will be out of phase and will sound unnatural.  
Unnecessarily long, or very thin speaker cables may affect  
the sound quality and should be avoided.  
Be careful not to short the positive and negative wires.  
Doing so may damage the amplifier.  
Make sure the metal core of the wire does not have contact  
with the power amplifier’s rear panel. Doing so may  
damage the power amplifier.  
While using the M-5000R, the internal temperature will  
fairly rise. Excessive temperature rise may affect the  
amplifier performance. To prevent damage from occurring  
due to high internal temperatures, it is vital to have proper  
ventilation and passage of air to carry out the heat and  
keep the internal temperature within acceptable ranges.  
Caution  
• Do not place the M-5000R inside cabinets or closets  
where there is poor passage of air and ventilation.  
• Do not place the M-5000R near external heat sources  
such as heaters or hot air ducts.  
• Do not place other components or object on top of or  
under the M-5000R.  
• The cover of the M-5000R contains ventilation holes to  
allow the passage of air. Do not cover or block these  
holes in any way.  
Do not place the M-5000R near TV or radio. This may  
cause noise or instable video on radio or TV respectively.  
Power cord  
Do not use a power cord other than the one supplied with  
the M-5000R. The power cord supplied is designed for use  
with the M-5000R and should not be used with any other  
device.  
Be sure to only use wall sockets that properly fit the plug  
of the power cord. If the socket does not match the plug of  
the power cord, you will need to prepare an adapter.  
Always use an adapter that is properly certified for this  
application.  
Don’t connect more than one cable to each speaker  
terminal. Doing so may damage the power amplifier.  
Don’t connect one speaker to several terminals.  
(North American models)  
If you are using banana plugs, tighten the speaker terminal  
before inserting the banana plug.  
If you are planning to place it within a cabinet, either open  
holes in the rear panel of the cabinet to improve  
ventilation or use a fan to force air circulation.  
As a general rule, if during idling the cover is too hot to  
touch, then ventilation needs to be improved.  
Do not insert the speaker code directly into the center hole  
of the speaker terminal.

Care  
Power  
From time to time you should wipe the front and rear  
panels and the cabinet with a soft cloth. For heavier dirt,  
dampen a soft cloth in a weak solution of mild detergent  
and water, wring it out dry, and wipe off the dirt.  
Following this, dry immediately with a clean cloth. Do not  
use rough material, thinners, alcohol or other Chemical  
solvents or cloths since these could damage the finish or  
remove the panel lettering.  
WARNING:  
BEFORE PLUGGING IN THE UNIT FOR THE FIRST  
TIME, READ THE FOLLOWING SECTION  
CAREFULLY.  
AC outlet voltages vary from country to country. Make  
sure that the voltage in your area meets the voltage  
requirements printed on the unit’s rear panel (e.g., AC  
230 V, 50 Hz or AC 120 V, 60 Hz).  
Whenever performing maintenance on the M-5000R, any  
of its supplied accessories, or any device connected to it,  
do not use solvents or cleaners of any kind that are  
inflammable or combustible.  
When you clean the input/output terminals on the rear  
panel, do not use contact restorer. Doing so may cause  
resin deterioration.  
By factory default, the meters are treated with antistatic  
coating. Do not strongly wipe the surface with a cloth to  
avoid static electricity from building up, as this may cause  
an oscillation of the needle.  
Other  
Below is a list of actions that you should never perform.  
Do not use the M-5000R as a broadcast system or  
musical instrument amplifier.  
Never use a generator, DC/AC converter, AC/AC  
converter, or transformer to supply power for the  
M-5000R.  
Never perform a “thumb test” (checking whether current  
is reaching the lead wire on the hot end of the input by  
touching it with your fingers) on the ends of the input  
jacks or input cables.  
Doing so may damage the speakers.  
Do not short across the output terminals or across the  
output terminals and rear panel.  
Never remove the cover of the M-5000R.  
Do not install the M-5000R in a location within the  
reach of small children.  
Lightning storms  
During lightning storm, never touch the power cord, plug  
or cover of the M-5000R, and any devices connected to  
the M-5000R.

Technology  
A WRAT (Advanced Wide Range Amplifier  
Technology)  
The M-5000R employs a host of proprietary  
Onkyo technologies to ensure optimal audio  
performance.  
2. Low Negative-Feedback Design  
handle speaker impedance, fluctuations, which  
can force an amplifier to provide four to six  
times its usual current load. The M-5000R’s  
instantaneous current capability ensures that  
audio output is not affected by power  
limitations.  
Conventional amplifiers make extensive use of  
negative feedback (NFB), whereby part of the  
output signal is re-input in order to improve the  
S/N ratio across a wide frequency range.  
However, too much NFB makes a system  
susceptible to counter-electromotive force from  
the speakers, resulting in a drop in perceived  
sound quality. To avoid this, Onkyo focuses on  
improving the frequency response and reducing  
distortion, without relying so much on NFB.  
We use a low negative-feedback design  
incorporating audiophile-grade, close-tolerance  
components, to achieve a frequency response,  
out to 100 kHz.  
1. DIDRC (Dynamic Intermodulation  
Distortion Reduction Circuitry)  
Since the advent of digital audio, the values of  
S/N (signal-to-noise) ratio have risen  
significantly. However, it is also recognized that  
in terms of perceived S/N, analog audio sources  
are not inferior to digital sources.  
Quad Push-Pull Amplification Design with  
Three-Stage Inverted Darlington Circuitry  
Three-Stage Inverted Darlington Circuitry  
brings greater efficiency to the M-5000R power  
amp by employing a low-NFB design to  
maintain voltage stability and enhance transient  
response. Extremely sensitive to oscillations,  
this circuitry requires very advanced control  
technology in order to be incorporated into the  
amplifier. Breaking further new ground, the  
M-5000R employs two extra transistors for  
each channel in a “quad push-pull” design that  
significantly enhances amplification power.  
Generally, S/N measures the ratio when sound  
is and not produced, but takes no account of the  
noise generated during sound reproduction.  
For a long time, Onkyo has focused and made  
extensive research on the S/N when sound is  
produced (dynamic S/N). Using a mechanism  
that captures the noise beyond audible range, it  
has been possible to determine that both  
dynamic S/N and perceived S/N aggravate  
during music reproduction.  
Although frequencies above 20 kHz are beyond  
human hearing, it is well known that a beat can  
be perceived if different signals are overlapped  
at such frequencies.  
During the analog audio era, no significant  
signals were entering beyond the audible range.  
However, the digital era has made recording  
beyond the audible range possible and the  
generated beat is now perceivable.  
3. Closed Ground-Loop Circuits  
If an amplifier’s ground potential (voltage)  
fluctuates during playback, noise is likely to  
result. In an open-loop circuit design, where all  
circuits (ire connected to the power supply via a  
single loop (as on many amplifiers), the noise is  
compounded. To avoid this, the M-5000R  
employs a sophisticated closed-circuit design in  
which each circuit has a separate link to the  
power supply. This helps to cancel individual  
circuit noise and keep the ground potential free  
of distortion.  
Symmetrical Twin-Monaural Construction  
Power devices for the left and right channels of  
the M-5000R are aligned symmetrically. Each  
channel has the same electrical and structural  
design, and signal pathways are uniform in  
length. This helps to minimize errors in  
stereophonic playback.  
4. HICC (High Instantaneous-Current  
Capability)  
Side-mounted Circuit Board Construction  
Rather than being directly connected to the  
chassis base, the circuit boards inside the  
M-5000R are cushioned by internal struts and  
affixed to the front, side, and rear panels. This  
method of construction prevents vibrations  
from the chassis from adversely affecting the  
circuit boards.  
When an amplifier outputs an audio signal, the  
connected speakers accumulate energy, reflex,  
and send energy back to the amplifier. The  
amplifier must then immediately cancel the  
speakers’ reflex energy and instantaneously  
send out the next signal. The same high current  
required to achieve this is also necessary to  
With Onkyo's DIDRC technology, a new  
approach is introduced which prevents such  
beat from penetrating the audible range.

Tip  
Note  
• See “Setting Auto Standby (ASb)” for the auto standby function  
(21).  
• After a certain period of warming up, the temperature of the  
power amplifier’s components and internal temperature are  
stabilized, and the sound will soften.  
Note  
• The power amplifier remembers the state when power was  
previously turned off, and returns to the state.

You can switch the power output of speaker terminals  
between ×1 (default) and ×10 (10 times).  
When AUTO STANDBY is turned ON side, the power  
amplifier will automatically enter Standby mode if the  
power amplifier receives no signal for 3 hours.  
Press METER RANGE repeatedly to switch

`ON:  
ASb enabled.  
`OFF:  
ASb disabled.  
The number of watts indicated on the meters corresponds  
to the actual output level when driving speakers rated at 8  
ohms. When driving speakers rated at 4 ohms, the output  
is actually twice that shown on the power meters.  
Default setting: ON (European models), OFF (North  
American models)  
Once the ASb function has been activated, the power  
amplifier will not automatically turn on even if it receives  
the signal. To turn on the power amplifier, press  
ON/STANDBY manually. You can also disable the  
function by setting this switch to OFF side.  
Note  
• Before entering standby mode with the Asb function, the Off  
LED flashes 30 seconds before the ASb function starts running.

Can’t turn on the Power Amplifier.  
There’s no sound.  
The 12V trigger does not work.  
• Make sure that the power cord is properly plugged into  
the wall outlet (16).  
• Unplug the power cord from the wall outlet, wait 5  
seconds or more, then plug it in again.  
• Make sure the speakers are connected correctly (15).  
• Check all connections and correct as necessary (15).  
• When making XLR IN input, make sure that the INPUT  
SELECT switch is switched to the XLR side.  
• Make sure the correct input source is selected.  
• Make sure the analog audio cable is connected correctly.  
• Make sure that all audio connecting plugs are pushed in  
all the way.  
• Make sure the cables are connected to the jacks firmly.  
The power amplifier contains a microcomputer for  
signal processing and control functions. In very rare  
situations, severe interference, noise from an external  
source, or static electricity may cause it to lockup. In  
the unlikely event that this should happen, unplug the  
power cord, wait at least 5 seconds, and then plug it  
again.  
The Power Amplifier turns off  
unexpectedly.  
• When the set ASb starts running, the power amplifier  
will automatically go standby (21).  
The sound quality is not good.  
• If the power amplifier cannot start with the Standby LED  
blinking, then it may be problem with the power  
amplifier. If speaker cables touch the chassis, this may  
cause the power amplifier to short out and make sure the  
plus terminals of speaker cables do not touch the chassis  
or the minus terminals.  
Before disconnecting the power cord from the wall  
outlet, set the main power switch to OFF.  
• Make sure the speaker cables are connected with the  
correct polarity (15).  
• Make sure all audio connecting plugs are pushed in all  
the way (15).  
• The sound quality can be affected by strong magnetic  
fields, such as that from a TV. Try moving any such  
devices away from the power amplifier.  
• If you have any devices that emit high-intensity radio  
waves near the power amplifier, such as a cellular phone  
that’s being used to make a call, the power amplifier  
may output noise.  
If during idling the cover is too hot to touch, then  
ventilation needs to be improved.  
Please try the method below:  
Set the POWER switch to OFF and disconnect all  
speaker cables. Check that the top of the set (cooling  
vent) is not blocked. When the power amplifier has  
cooled down, reconnect all speaker cables and set the  
POWER switch to ON. Then Press ON/STANDBY.  
• When making RCA IN input, make sure that the INPUT  
SELECT switch is switched to the RCA side.  
• Check the connection in case of bi-amping connection.  
Audio performance  
• Audio performance will be at its best about 10 to 30  
minutes after the power amplifier has been turned on and  
had time to warm up.  
• Using cable ties to bundle audio cables with speaker or  
power cables may degrade the sound quality. So don’t  
do it.
