To ensure years of enjoyment from your NADY AUDIO PMX-420, please read and understand this manual thoroughly before  
using the unit.  
INSPECTION  
Your NADY AUDIO PMX-420 powered mixer 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.]  
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. Also, do not place the PMX-420 powered mixer on high temperature  
devices such as power amplifiers, etc., or the unit may overheat in operation.  
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.  
Please make sure that the power unit supplied is marked for the correct voltage in your area (120VAC/60 Hz or  
230VAC/50 Hz). Power requirements for electrical equipment differ from area to area. In new installations and portable  
sound systems, or any situation in which the AC power is in question, it is wise to confirm the voltage and use the  
appropriate power supply unit before connecting it to power sources.  
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. Set the Channel  
(11), Submix (16), and Master Stereo Volume Faders (19) to minimum to further reduce the chance of undesired noise  
when first powering up. Turn on your PMX-420 powered mixer by pressing on the rear panel Power On/Off Switch (35).

(5) CHANNEL PEAK LED  
(2)  
The Peak LED illuminates when  
a channel input is overloading.  
(5)  
(4)  
It detects the peak level after  
the Equalizer Controls (6) and  
will light just before clipping to  
warn that the signal is  
approaching overload. You do  
not want the Peak LED to light  
except very intermittently. If it  
lights persistently, reduce the  
Gain Control (4). If the Gain  
control is set to minimum, the  
output level of the preceding  
equipment should be lowered.  
(1)  
(3)  
(6)  
(6) EQUALIZER CONTROLS  
All channels are fitted with a  
three-band EQ - High, Mid and  
Low controls. 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 High and Low  
shelving controls have their  
frequencies fixed at 12 KHz and  
100Hz respectively and the Mid  
control is fixed for peak  
response at 1KHz. The  
channel EQ is a valuable  
feature of the mixer as it allows  
the user to control the tonal  
characteristics of each channel  
separately. For example,  
(1) CHANNEL 1 & 2 INPUTS  
These electronically balanced XLR inputs are designed to  
accept signals from any balanced or unbalanced low  
impedance (Low Z) microphone. They can also be used to  
accept line level signals when the Gain is turned close to  
minimum. The XLR jack is configured: Pin1 = ground, Pin 2 =  
positive (+), Pin 3 = negative (-).  
(7)  
The 1/4” unbalanced inputs are designed to accept unbalanced  
Mic or Line level signals such as those from keyboards, drum  
machines, or samplers. It will be necessary to adjust the input  
Gain Control (4) to achieve a nominal operating level with no  
clipping. The Gain Control should be set closer to minimum  
when using Line level input signals. All four inputs can be used  
simultaneously to accommodate the use of four audio sources.  
(8)  
(9)  
(11)  
(10)  
(2) CHANNEL 3/4 & 5/6 STEREO INPUTS  
These 1/4” and RCA unbalanced inputs are designed to accept  
line level signals (max 1V / 2.3dBm) such as those common to  
CD/tape players, keyboards, direct outputs and home stereo or  
DJ equipment.  
boosting the Low can fatten the  
sound, add bass to vocals, or  
extra punch to bass, drums and synths.  
Channel 3/4 1/4” inputs can also be used as standard mono  
line inputs by plugging into the L input only. This signal will be  
routed equally to the Pan control and the left and right outputs  
in the same way as the standard line input channels.  
The Mid control can be used to increase midrange, fatten  
guitars, or bring warmth to vocals. Adjusting the High control  
can provide a crisp sounding high end. Another very important,  
yet often overlooked technique is to use the EQ to subtract  
from the mix. Cutting the High control can reduce unwanted  
sibilance, hiss, cymbals, or high frequency feedback, while  
attenuating the Mid or Low can also eliminate feedback or clear  
up a muddy sounding mix. The Mid Freq control can also be  
used to reduce any feedback. Cutting the High and Low, then  
pushing up the Channel Volume Control (11) is equivalent to  
mid range boost!  
For each channel there are separate A and B stereo inputs.  
Either A or B inputs can be selected using the Input Selector  
Switch. This allows the user to switch to a different input  
source instantaneously. This is very helpful for DJ when  
switching to different source material or for musicians who  
change instruments.  
(3) INPUT SELECTOR BUTTONS  
These select either A or B input sources for channels 3/4 and  
5/6.  
[Note: Always reset a channel’s input Gain Control (4) after  
altering the amount of equalization to avoid input overload.]  
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.  
(4) GAIN CONTROL  
The Gain control adjusts the input sensitivity (channel gain) of  
the inputs. This control can be adjusted to accommodate input  
signals from a wide variety of sources, from the high outputs of  
keyboards and drum machines to the small signal outputs of  
microphones. The best balance of S/N and dynamic range will  
be achieved if you adjust the Gain control on each channel  
separately so that the Channel Peak LED (5) almost lights.  
(7) EFFECTS SEND CONTROL  
This control adjusts the level of signal sent to the Effects Send

C O N T R O L S A N D C O N N E C T I O N S  
bus or the internal DSP Echo Effects. The channel Effects Send  
2. MASTER AND EFFECTS SECTION  
control is mono, post-EQ, and post-Ch Volume meaning the  
signal level sent to the Effects Send bus will be affected by the  
Channel Volume Control (11) setting. For almost all effects  
send purposes, post-volume is desirable  
(23)  
(13)  
(24)  
so that when a Ch Volume level is  
adjusted, any reverb send from that  
channel follows the volume. Otherwise,  
when the volume is turned down, the  
reverb from that channel would still be  
(14)  
audible. You can also use this effect  
send to feed inputs of a multi-track  
recorder or any other unbalanced line  
level application.  
(21)  
(20)  
(8) PAN  
The channel Pan positions the output of  
the channel in the left/right stereo field of  
the Master mix and also pans between (12)  
S1 and S2 in the Submix. Its constant-  
power design ensures there are no level  
discrepancies whether a signal is hard-  
(22)  
(18)  
(17)  
(16)  
panned, center-stage, or somewhere in-  
between.  
(15)  
(9) SUBMIX 1 & 2 SELECT BUTTON  
When the Channel S1/S2 button is  
selected (button depressed), the  
channel signal is fed to the Submix 1 &  
(8)  
(19)  
2 bus, controlled by the Submix 1 & 2  
Volume Faders (16), as well as the  
(9)  
Main Left and Right bus. This signal is  
post channel Volume and the placement  
(11)  
(10)  
between Sub 1 and Sub 2 is adjusted by  
the Pan control. The Submix bus offers  
you a second stereo submix with its own  
stereo Sub 1 and Sub 2 master faders  
and Sub outputs. The Submix can be  
used as a mixing aid both live and in the  
studio; for example, to combine certain  
signals to send to a monitor feed, external power amp, or to an  
external effects processor. It can also be used as a stereo  
headphone mix if faders are desired for controlling headphone  
volume. Using the Submix 1 & 2 Send/Return Inserts (29), the  
Sub signal can be sent out to an external effects processor and  
then returned into the mixer and mixed onto the Main Left and  
Right bus allowing these more sensitive faders to adjust the  
returned signal level.  
(12) EFFECTS SEND LEVEL CONTROL  
This control adjusts the final mixed level of the channel Effects  
Send signals. This signal is then sent to either the internal Echo  
Effects DSP or the Effects Send Output (27). Plugging into  
either the Effects Send Output (27) or Effects Return Input  
(28) jack will automatically disable the internal Echo Effects. The  
Effects Send signal can be output to an effects processor, multi-  
track recorder, or used for any other line-level auxiliary purpose,  
such as monitor feeds.  
(10) CHANNEL PFL BUTTON  
This button sends the pre-volume channel signal to the PFL bus  
for monitoring the input signal with headphones before increasing  
the channel volume into the mix.  
(13) ECHO EFFECTS DELAY TIME  
This rotary wheel can be used to select one of 16 preset time  
intervals of the built-in Echo Effects DSP between settings 0 - F  
as shown on the Echo Effects Display (14). Setting 0 - 2 selects  
the shortest echo time to emulate plate and doubling effects  
whereas settings 7 - F enables the longest echo time for stadium  
reverbs and delay sounds. Settings around 3 - 6 emulate room  
and hall reverbs by adjusting the Repeat Control (15) to approx  
ten o’clock.  
(11) CHANNEL VOLUME CONTROL  
This adjusts the volume level of each channel signal sent to the  
Effects, Submix, and Main Left & Right.

(14) ECHO EFFECTS DISPLAY  
This numeric LED display will indicate which of the 16 echo  
presets has been selected (0 - F).  
Right, the top red Peak LED will light when the powered output  
signal is just below clipping. It is acceptable if the red LED lights  
occasionally. If the red LED lights more than occasionally, you  
should turn down the Main Left & Right Volume Faders (19) to  
avoid audible distortion and clipping, which can cause damage to  
your speakers and even the internal amplifier.  
(15) ECHO EFFECTS REPEAT CONTROL  
This control adjusts the number of repeats and feedback/depth of  
the echo effect. Turning the control clockwise sets the repeats to  
maximum for lengthy stadium echoes or plate effects. Turning the  
control counter-clockwise sets less repeats for doubling effects.  
[Caution: Prolonged use at levels above clipping can cause  
damage to your speakers and even the internal amplifier.  
Carefully monitor the bargraph meter to avoid prolonged  
clipping.]  
The Effects Channel Pan Control (8), Submix 1 & 2 Select  
Button (9), PFL Button (10), and Channel Volume Control (11)  
all operate same as the other channels on the internal Echo  
Effects signal or the Effects Return signal.  
(22) HEADPHONE SELECT SWITCH  
This switch is used to set which signal will be sent to the  
Headphones Output (26). Main Stereo Left & Right signals are  
sent when set to L - R. When set to S1 - S2, Submix 1 is heard  
on the left and Submix 2 on the right. The signal of any channel  
with its PFL Button depressed is heard when the switch is set to  
PFL.  
(16) SUBMIX 1 & 2 VOLUME FADERS  
These faders adjust the level of the Submix 1 & 2 signals that are  
sent to the Submix 1 & 2 Outputs (30). These faders are post  
Submix 1 & 2 Send/Return Inserts (29) and will control any  
signal returning to the PMX-420 via those jacks. The Submix  
signal can also be selected for the Headphone Output (26) for  
easy monitoring. The Submix can be a very useful feature if  
used effectively The Submix can be used as a mixing aid both  
live and in the studio; for example, to combine certain signals to  
send to a monitor feed, external power amp, or to an external  
effects processor. This submix can also be added to the  
Main/Master mix by depressing the Submix to L-R

These 1/4” jacks output the Submix 1 & 2 unbalanced line level  
signals.  
[Caution: Make sure that the speaker, connectors and wiring  
can handle the rated output power to avoid damage. Note that  
prolonged use at levels above clipping can drive the amplifier  
into thermal runaway and damage the internal amplifier and  
speaker, so care must be taken to not overload the amplifier.  
Never use less than 4 ohms total impedance for either channel  
as this can also cause the amplifier to overheat and create  
thermal runaway.]  
(31) MAIN LEFT & RIGHT SEND/RETURN INSERTS  
These 1/4” TRS insert jacks can be used to send out the Main  
Left & Right signals to an external device and return the signals  
via the same jack. They are pre-Main Left & Right Volume fader  
and allow for routing the signal through external devices such as

cause a serious safety hazard and will immediately void your  
warranty.]  
(33) LOW-PASS LEFT & RIGHT OUTPUTS  
(38) FUSE COMPARTMENT  
These 1/4” jacks output unbalanced line level signals that have  
been filtered through a Low Pass filter. This output is perfect for  
feeding directly to an amplifier that powers a subwoofer speaker  
or to a powered subwoofer with no crossover necessary. The  
frequency response is 30Hz - 150Hz (-6dB) with a -12dB roll-off  
point at 250Hz. These signals are post Main Left & Right faders.  
Replace with only the same type fuse. If the fuse blows  
continuously, have the unit serviced by qualified personnel. The  
PMX-420 powered mixer uses 20mm glass tube Fast Blow  
fuses: 5A 250V for 115VAC, 2.5A 250V for 230VAC.
