INSTALLATION
To ensure years of enjoyment from your NADY AUDIO PRM-400 powered mixer console, please read this manual thoroughly
before using the unit.
1. INSPECTION
Your NADY AUDIO PRM-400 was carefully packed at the factory in packaging designed to protect the units in shipment.
Before installing and using your unit, carefully examine the packaging and all contents for any signs of physical damage that
may have occurred in transit.
[Please note: Nady Systems is not responsible for shipping damage. If your unit is damaged, do not return to Nady, but
notify your dealer and the shipping company (if shipped to you) immediately to make a claim. Such claims must be made by
the consignee in a timely manner.]
2. RACK MOUNTING
Enclosed in the shipping box you will find a rackmount kit. If you want to make your PRM-400 a rack mixer, remove the
screws from the side panels and use them to attach the rack ears.
(Note: The rack ears are supplied as “left” and “right” and must be attached as such.)
3. SETUP AND OPERATION
Parts of the unit can become very warm during use. This is normal during operation. Care should be taken to ensure that
there is enough space around the unit for cooling (at least 12” or 30cm). Do not place the PRM-400 on high temperature
devices such as power amplifiers, etc., or the unit may overheat in operation. Also, do not place the unit on speakers as this
may cause them to move and/or fall due to speaker vibrations.
Although the unit’s chassis is shielded against radio frequency (RF) and electromagnetic interference (EMI), extremely high
fields of RF and EMI should be avoided.
The PRM-400 has an internal power supply and is designed to operate from an external AC source. Power requirements
for electrical equipment differ from area to area. Be sure to confirm that the voltage selected by the voltage selector switch
on the back panel is proper for your area (120VAC/60 Hz or 230VAC/50Hz) per the information below:
Europe (except UK): 230V, 50Hz
UK and Australia: 240V, 50Hz
USA and Canada: 120V, 60 Hz
For other areas, please check with local authorities.
When ready to operate, plug the AC cord into the power source. Make sure that the unit is turned off before connecting to
the AC power source to avoid possible loud transients which can damage your speakers or your ears, especially when mon-
itoring with headphones. Set the noted controls to the positions indicated below to further minimize the chance of undesired
noise when first powering up your PRM-400 :

CONTROLS AND CONNECTIONS
1. CHANNEL INPUT SECTION
which are usually added to the dry signal, dynamic process-
(1) MIC INPUT
ing is normally applied across an entire signal. Here an Aux
Send would be inappropriate. Instead, the signal is intercept-
ed somewhere along the channel, fed through the dynamics
processor and/or EQ, then returned to the console at the
same point where it left. The insert point is normalized, i.e.,
the signal is only interrupted when a plug is plugged into it.
The insert jack is located post EQ in the channel and is con-
figured as: Tip = send, Ring = return, Sleeve = ground. The
Insert can also be used as a channel direct output by sending
the signal from the ring. To use the Insert as a direct output,
insert a 1/4” phone plug halfway into the Insert jack so the tip
of the plug connects with the ring of the insert jack. The jack
will click into place when the connection to the ring is made.
The Mic input is an elec-
tronically balanced XLR
type designed to accept
signals from any bal-
anced low impedance
(Low Z) microphone. To
accommodate condenser
microphones, this input is
also equipped with
+48VDC phantom power

The trim control adjusts the input sensitivity (channel gain) of
the Mic and Line inputs on the input channels. This control
can be adjusted to accommodate input signals from a wide
variety of sources, from the high outputs from keyboards or
drum machines to the small signal outputs of microphones.
The trim control adjusts the input sensitivity from -20dB to
-60dB with the -20dB Pad

[Note: The Mic inputs are more sensitive than the Line inputs.
Also, do not connect mics with the phantom power switched
on, as indicated by the Phantom Power On LED (24) in the
Master Section of the front panel. Never use unbalanced mic
cables with the Phantom Power switched on. Never short the
+48VDC to ground, as that can cause serious damage to
your mixer. Also, turn down the Stereo Master faders (27A,
27B) to prevent possible sharp transient noise from damaging
the speakers when turning the phantom power on or off.]

TRIM control on each
channel separately so that

occasionally.
(2) LINE INPUT
(4A) PEAK LED INDICA-
TOR
The Line input is designed to accept balanced or unbalanced
line-level signals such as those from keyboards, drum
machines, or samplers. There is enough gain available on the
line input to accept even lower level signals, such as those
from an unbalanced microphone or guitar output. Use the
Trim control (4) and/or Pad switch (5) to adjust for the
desired level. If a balanced signal is to be connected to the
line input, then a 1/4” TRS (stereo) phone plug should be
wired for: Tip = positive (+), Ring = negative (-), Sleeve =
ground.
The Peak LED illuminates
when a channel is going
into overload. It detects
the peak level after the EQ
and will light at approxi-
(6)
mately 5dB before clipping
to warn that the signal is
approaching overload. You
do not want the Peak LED
to light except very inter-
mittently during a take or a
mix. If it does light persist-
ently, reduce input gain
with the TRIM control (4)
or PAD (5).
(Note: Only the Mic or the Line input of a given channel can
be connected at one time. Never connect both simultaneously
to the same channel.)
(3) INSERT
All 6 channels are equipped with insert jacks to connect
external signal processors such as compressors, noise reduc-
tion systems, or effects devices to the individual input chan-
nels. Insert points are useful for adding dynamic processing
or equalization to a channel or the mix. Unlike reverbs, etc.,

CONTROLS AND CONNECTIONS
(5) PAD
The key to successful equalization is to avoid excess. Too
much equalization on the input channels will result in a mix
that is smeared together with nothing specifically defined.
During rehearsals, experiment with the equalizer controls on
various instruments, vocals and combinations of these mixed
together to become familiar with various equalizer settings.
This control attenuates the
input signal -20dB when
set to the IN (button
depressed) position.

(8)
(6) EQUALIZER CON-
TROLS
(7) AUX (POST) SEND CONTROLS
All input channels are fit-
ted with a three-band EQ.
All three bands have up to
15 dB of cut and boost,
with a center detent for
“off”. The frequency
response is flat when all
three EQ knobs are in the
center detent position. The
upper and lower shelving
controls have their fre-
quencies fixed at 12 kHz
and 80 Hz respectively.
The midrange control has
a peaking response at
2.5KHz (Q fixed at 1
The Aux send controls are mono and post-EQ and pre-fader
and the signal level sent to the AUX bus will be unaffected by
the channel fader setting. This configuration is ideal for
almost all monitoring purposes, for example, for a separate
stage monitor mix in live performances or a studio room mon-
itor in recording applications, such as for a headphone cue
system.
(9)
(8) EFF (EFFECTS) CONTROLS
The EFF control are mono, post-EQ and pre-fader and the
signal level sent to the EFFECTS bus will be unaffected by
the channel fader setting. These controls adjust the level sent
by each channel to the internal DSP (Digital Sound
Processor). (See also Digtal Echo Effects Function and
Operation)

octave). The channel EQ
is a valuable feature of the
mixer as it allows the user
to control the tonal charac-
teristics of each instrument
separately. For example,
boosting the LOW can fat-
ten the sound and add
punch to the bass or
drums; the MID control
can be used to define the
midrange or bring out the
vocals; and adjusting the
HIGH control can provide
a crisp sounding high end.
Another very important,
yet often overlooked tech-
nique is to use the EQ to
subtract from the mix.
(9) PAN
The Channel Pan positions the output of the channel in the
stereo field of the main mix. Its constant-power design
ensures there are no level discrepancies whether a signal is
hard-panned, center-stage, or somewhere in between.
(10) PFL SELECT SWITCH
The PFL (pre-fader listen) switch enables monitoring the sig-
nal of any channel(s) selected (button depressed) at nominal
levels through the headphone output. The signal is post EQ
and independent of channel fader position. Selecting the PFL
never interrupts the main stereo out or the AUX sends.
(11)
(11) CHANNEL FADER
The channel faders determine the output signal level to the
Master Mix Left, Right busses. They offer a smooth logarith-
mic taper for optimum control of the signal, more often asso-
ciated with much more expensive consoles.
Cutting the HIGH control
can reduce unwanted hiss
during multi-track record-
ing, while attenuating the
MID or LOW can eliminate
feedback in a live perform-
ance or clear up a muddy sounding mix. Cutting away the top
and bottom, then pushing up the Gain is equivalent to mid
range boost!
[Note: Always reset a channel’s input Gain (or external
device’s output level) after altering the amount of mixer equal-
ization cut or boost applied.]

Return jack, the Aux Return will operate in mono and the sig-
nal will be routed to the Aux Return Control (31) and then
mixed into the left and right Master Mix bus. The Aux Return
is multi-functional. It may be used for returning the outputs of
effect units such as Tape Returns from a multi-track recorder,
or as extra instrument inputs such as from a MIDI keyboard.
(15) STEREO MASTER INSERTS-POST EQ
The final Master Mix is output directly to the Main Speaker
outputs (42). These L/R outputs provide 200W at 4 ohms for
powering P.A. speakers rated for this power or more. Channel
A and B parallel outputs allow multiple speaker setups. You
can also access this Master Mix by utilizing the send function
of the Stereo Master Inserts (see below). The Record Out
(17) jacks output the Master Mix post-Stereo Master faders
(27A, 27B) and are pre-Master EQ (22) and pre-Stereo
Master Inserts (14,15). These outputs are RCA jacks, and
designed primarily for inputs to tape recorders, etc.
(12) AUX SEND
(30) MASTER AUX SEND CONTROL
The Aux Send jack is the unbalanced output for the signals
from the Aux bus. It is pre-fader. This signal can be sent to
the input of an effects processor, multi-track recorder, or used
for any other line-level auxiliary purpose, such as monitor
feeds. The Aux Send level is adjusted by the channel Aux
Send controls (7) and the Master Aux Send control (30).
When the Aux/Mon switch (26) is in the depressed IN posi-
tion, the Aux send also functions as the mono output of the
Master Right Channel bus. (See also Master Mix Function
and Operation below)
The output level routed to the Speaker outputs and REC out-
puts is determined ultimately by the setting of the Stereo
Master faders (27A, 27B). The Master Mix (signal on the
L/R main busses) is the sum of the signals routed from all the
channels and also the inputs from the EFFECTS and AUX
busses and the TAPE Input (16). The level input from the
Tape In (16) is adjusted with the Tape In Level control (29).
The level of signal routed to the Stereo Master faders
(27A,27B) from DAT, tape decks, CD players, etc., input to
the Tape Input (16) is determined by the setting of the output
volume control of the audio device being connected and the
Tape In Level Control (29), so care must be taken in adjust-
ing these levels so as to achieve proper balance in the final
mix and to prevent overload distortion. The 10-stage LED
Output Meter (19) can be used to maintain proper levels in
the master mix.

The PRM-400 is equipped with a 7-
(20)
(21)
band Stereo Graphic Equalizer
(22), allowing final tonal adjustments
on the Master Mix. This master EQ
is post-Stereo Master faders
(27A,27B) so you must exercise
care in the proper use of these EQs
for best overall sound [see also
INPUT SECTION, (6) EQ above].
The EQ Bypass switch (25) can be
used to add or eliminate the Stereo
EQ from the Master Mix (button
depressed=EQ bypassed).
(19)
(19A)
(24)
Further processing of the Master
Mix can be done by utilizing the
stereo Master Inserts (14,15). The
PRE EQ insert (14) inserts a signal
from an outboard processor, as
desired, between the Stereo Master
faders (27A,27B) and the Stereo
Graphic Equalizer (22), while the
POST EQ insert(15) inserts it POST
EQ and before the PRM-400 internal
power amp. The insert points are
normalized, i.e., the signal is only
interrupted when a jack is plugged
into it. The insert jacks are config-
ured as: Tip = send, Ring = return,
Sleeve = ground.
(23)
(25)
(26)
(22)
The Inserts can also be used as
Master Mix pre or post-EQ direct
outputs by sending the signal from
the ring. To use an insert as a direct
output, insert a 1/4” phone plug
halfway into the insert jack so the tip
of the plug connects with the ring of
the insert jack. The jack will click
into place when the connection to
the ring is made. Such outputs can
thus serve as feeds for external
amplifiers or recording devices, for
example.

The Aux/Mon Select switch (26)
can be used to switch between nor-
mal stereo L/R to dual mono opera-
tion, such as for powering separate
mains and monitor speakers with
the PRM-400. The UP position is for
stereo operation as described
(28)
above, and the DOWN (depressed)
position enables dual mono opera-
tion as follows: The Left speaker
output is a mono mix of both the

signal controlled by the Channel AUX controls (7).
Therefore the Main speakers, for example, can be controlled
by the individual Channel faders (11) and the Left Master
fader (27A), and the Monitor speakers by the Channel AUX
controls (7) and the Right Master fader (27B). In this
mode, any Master EQ (22) or Effects (8,28,32) selected on
the EFECTS bus will be output on both the Left and Right
Speaker outputs. The Left and Right Master inserts (14,15)
operate individually on either channel as in normal stereo
