To ensure years of enjoyment from your NADY AUDIO PMX Series, please read and understand this manual thoroughly before using the unit.

INSPECTION

Your NADY AUDIO PMX Series 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 OPERATOIN

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 Series 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 (13), Group (22), and Master Stereo Volume Faders (24) to minimum to further reduce the chance of undesired noise when first powering up. Turn on your PMX Series powered mixer by pressing on the rear panel Power On/Off Switch (38).

For other areas, please check with local authorities.

to the individual input channels. Insert points are useful for adding dynamic

 

 

 

 

 

 

 

 

 

 

 

 

processing or equalization to a channel or the mix. Unlike reverbs, etc., which

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

are usually added to the dry signal, dynamic processing is normally applied

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(9)

across an entire signal. Here an Aux Send would be inappropriate. Instead, the

 

 

 

 

 

 

 

 

 

 

 

 

signal is intercepted somewhere along the channel, fed through the dynamics

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

processor and/or EQ, and 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

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(10)

plug is plugged into it. To use Inserts as a Send/Return, an insert cable is

 

 

 

 

 

 

 

 

required which will split the 1/4” TRS insert connection to two plugs, one for

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(11)

Send and one for Return. The insert jack is pre EQ in the channel and is

 

 

 

 

 

 

 

 

 

 

configured as: Tip = send, Ring = return, Sleeve = ground.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(12)

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

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

(5)

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

(4) TRIM CONTROL

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Trim control adjusts the input sensitivity (channel gain) of the Mic and Line

 

 

 

 

 

 

 

 

inputs on the 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 with 30dB of range. The best balance of S/N and dynamic range will be achieved if you adjust the TRIM control on each channel separately so that the Channel Peak LED (5) for that channel almost lights.

5

C O N T R O L S A N D C O N N E C T I O N S

(5) CHANNEL PEAK LED

The Peak LED illuminates when a channel input is overloading. It detects the peak level after the Equalizer Controls (7) 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 Trim Control (4).

(6) LOW CUT FILTER

Use this Low-Cut (high-pass) filter (18 dB/octave, -3 dB at 75Hz) for reducing floor rumble, popping, breathing noises, woolly bottom end, and to tighten up channels in a mix, etc. It is most effective when used carefully in conjunction with the Equalizer Controls (7).

(7) EQUALIZER CONTROLS

All channels are fitted with a three-band EQ — High, Mid and Low controls. The Mid control has a parametric Mid Freq control with a 250Hz-6KHz range. 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 80Hz respectively. The Mid control has a parametric Frequency Control. This control can be used to locate the frequency of the midrange tones that you want to accentuate or cut. 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, boosting the Low can fatten the sound, add bass to vocals, or extra punch to bass, drums and synths. The Mid control, with the Mid Freq set to higher frequencies, can be used to define percussive instruments or bring out the edge of vocals; when set to lower frequencies the Mid can boost low midrange frequencies to fatten up guitars, toms, 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 from 250Hz to 6Khz. Cutting the High and Low, then pushing up the Channel Fader (13) is equivalent to mid range boost!

[Note: Always reset a channel’s input Trim Control (4) (or external device’s output level) after altering the amount of equalization.]

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.

(8) AUX 1 CONTROL (PRE-FADER)

The channel Aux 1 control is mono, post-EQ, and pre-fader meaning the signal level sent to the Aux Send 1 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

monitor in recording applications, such as for a headphone cue system.

(9) AUX 2 / EFFECT CONTROL (POST-FADER)

This control adjusts the level of signal sent to the Aux Send 2 or the internal DSP Echo Effects.

The channel Aux 2 control is mono, post-EQ, and post-fader meaning the signal level sent to the Aux 2 bus will be affected by the channel fader setting. For almost all effects send purposes, you will want to use the post-fader Aux 2, so that when a fader level is adjusted, any reverb send from that channel follows the fader. Otherwise, when the fader is pulled down, the reverb from that channel would still be audible. You can also use this Aux 2 send to feed inputs of a multi-track recorder or any other unbalanced line level application. On the other hand, for cueing purposes and monitor amplifiers, use the pre-fader Aux 1 (i.e. independent of the channel fader).

The Aux 2 Effect Send controls also adjust the level sent by each channel to the internal DSP (Digital Sound Processor) Echo Effects. Either the Aux Send 2 or internal Echo Effects can be selected with the Aux 2 / Eff Enable Button (15).

(10) PAN

The channel Pan positions the output of the channel in the left/right stereo field of the Master mix and also pans between 1 and 2 in the Group mix. Its constant-power design ensures there are no level discrepancies whether a signal is hard-panned, center-stage, or somewhere in-between.

(11) L-R SELECT SWITCH

When the L-R switch is selected (button depressed), the post fader channel signal is fed to the Master Stereo Volume Faders (24).

(12) GROUP SELECT SWITCH

When the G1-2 switch is selected (button depressed), the channel signal is fed to the G1-2 bus, controlled by the Group 1- 2 Volume Faders (22). This signal is post channel fader and the stereo placement is adjusted by the Pan control. The Group bus offers you a second stereo submix with its own stereo G1-2 submaster faders. This submix can be sent to the Master Stereo Volume Faders (24) by enabling the Group To Main Switch (23). The Group Mix can be used as a convenient mixing aid both live and in the studio; for example, to combine the outputs of all drum channels onto just 1 or 2 submaster faders, or to mix together a vocal quartet and then control their combined level in the Master Mix, or to route separately to multi-track recorders. The Group Select Switch can also be used to monitor the channel signal in the headphones, without sending the signal to the main outputs, with the L-R Select Switch (11) off.

(13) CHANNEL FADER

The channel faders determine the output signal level to the Master Mix or Group 1-2 buses. They offer a smooth logarithmic taper more often associated with much more expensive consoles for optimum control of the signal.

2. AUX EFFECTS SECTION

(14) AUX SEND 1 & 2 LEVEL CONTROLS

These controls adjust the final mixed level of the channel Aux 1 and Aux 2 auxiliary signals separately. These signals are then sent to the Aux Send 1 & 2 Outputs (30) respectively. These signals 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. If the signal is going to be used for an external reverb/delay device, preferred instead of the internal Echo Effects, Aux Send 2 should be used and the Aux 2 / Effects Enable Switch (15) should be set to Aux 2 (button out). This will disable the internal Echo Effects. When the switch is depressed, the Aux 2 level control and output are disabled.

(15)

(14)

(29)

(28)

(27)

(26)

(15) AUX 2 / EFFECTS ENABLE SWITCH

(21)

This push button switch determines if the Channel Aux 2

 

Eff Send signals are sent to Aux Send 2 (button out) or to

 

the internal Echo Effects section (button depressed). The

 

Aux 2 Level Control (16) and output are disabled when

 

this button is set to enable the internal Echo Effects. Note

 

the Aux Return 2 is operational regardless of this switch

 

setting.

(23)

(16) AUX RETURN 1 & 2 LEVEL CONTROLS

 

These controls adjust the signal level from the Aux Return

 

1 & 2 Inputs, which are then mixed into the Left and Right

 

Master bus. These can be used to return effected signals

 

into the PMX Series powered mixer or they can be used

 

as auxiliary inputs from line level devices such as

 

keyboards or Tape Returns of multi-track recorders. The

 

internal Echo Effects cannot be applied to these auxiliary

(22)

returns. Note, Aux Return 2 is operational regardless of

the Aux 2 / Effects Enable Switch (15) setting.

 

(17) ECHO EFFECTS TIME DELAY

This control sets the time interval, in milliseconds, of the built-in Echo Effects DSP (Digital Sound Processor). Lower settings select the shortest echo time to emulate plate

effects whereas higher settings enable the longest echo time for stadium reverbs and delay sounds with up to 200mS delays. Settings around 100mS emulate medium room and hall reverbs by adjusting the channel Effect Control (9) and Echo Depth (19) to nine o’clock, Echo Input Level (18) to 12 o’clock, and

Effect Volume Fader (20) to approximately -10dB.

(18) ECHO EFFECTS INPUT LEVEL

This adjusts the level of signal input into the Echo Effects DSP.

(19) ECHO EFFECTS DEPTH

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 echoes or plate effects. Turning the control counter-clockwise sets less repeats.

(20) EFFECT VOLUME FADERS

These faders adjust the final level of the effected tone applied to the Master bus.

(25)

(24)

3. MASTER CONTROL AND EQ SECTION

(21) DUAL CHANNEL GRAPHIC EQUALIZER

The 7-band graphic equalizers allow you to adjust the frequency response of the Master L and R mix providing a maximum of +/- 12dB of cut and boost for each frequency band from the center détente flat position. The top EQ is for the Left channel and the bottom EQ is for the Right channel. This EQ can be used to shape and mold the tone of your audio and easily eliminate feedback at notch frequencies without overly affecting your sound.

(22) GROUP 1 & 2 VOLUME FADERS

These faders adjust the level of the Group 1 & 2 submix signals that are sent to the Group Outputs (35) and can also be selected for the Headphone (33) and Control Room (34)

outputs for easy monitoring. The Group can be a very useful feature if used effectively. For stage applications the Group mix can be sent to a monitor amplifier so the performers will only hear the audio that is not already loud enough on stage. Subgroups are commonly used as a mixing aid both live and in the studio. For example, you can combine the outputs from all drum channels onto just the two Group faders. This submix can also be added to the Main/Master mix by depressing the Group to Main Switch (23).

(23) GROUP TO MAIN SWITCH

When this push-button switch is depressed, the Group submix is added to the Main/Master bus. This allows controlling the combined volume of multiple channels with only two faders, which can be useful when mixing a vocal quartet or multiple mics for grouped instruments like percussion or drum kits.

(24) MASTER STEREO VOLUME FADERS

This adjusts the final level of the Master Left & Right signals, that are sent to the Main (36), Headphone (33), and Control Room (34) Outputs and also to the Speaker Stereo Outputs (37).

(25) DUAL CHANNEL LED VU METER

These 10-stage stereo output LED meter displays will display the relative output level of the Left and Right Main (36) and Speaker Outputs (37). They can be used to maintain proper levels in the master mix. 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 Master Stereo Volume Faders (24) to avoid audible distortion and clipping, which can cause damage to your speakers and even the internal amplifier.

(26) POWER LED

This LED will illuminate when the unit is switched on.

(27) PHANTOM POWER

When this switch is depressed, +48V of phantom power will be supplied to the mic channels. The yellow LED will illuminate when the switch is depressed to ON.

[Note: When turning on the Phantom Power switch, turn the Master Volumes to minimum.]

(28) HEADPHONE / CONTROL ROOM

The volume control adjusts the level of the Headphone and Control Room Outputs. The push-button selector switch will determine which signal is sent to these outputs - depressed for Group 1 & 2, out for Master Stereo.

(29) TAPE LEVEL CONTROL

This control adjusts the level of the Tape Input signal applied to Master/Main bus.

(30) AUX SEND 1 & 2 OUTPUTS

These mono unbalanced 1/4” jacks output the auxiliary signals which can be adjusted by the Aux Send 1 & 2 Level Controls (14).

(31) AUX RETURN 1 & 2 INPUTS

These mono unbalanced 1/4” jacks enable convenient inputs to the Master/Main busses. If you connect a signal to the return jacks, the signal will be routed to the Aux Return 1 or 2 Level Controls (16) and then mixed into the left and right Master/Main bus.

(32) TAPE INPUT / RECORD OUTPUT

The Left and Right Tape Input RCA jacks allow cassette recorders, CD players, or MP3 players to be added to the Master/Main mix outputs. The input signals can be adjusted by the Tape Level Control (29). The Record Output RCA jacks provide a stereo signal output to recording devices, home audio equipment, or external amplifiers. These outputs are post Master Stereo Volume Faders (24).

(33) HEADPHONE OUTPUT

The Headphone 1/4” stereo output can be used to monitor either the Master or Group mix. It will power headphones with impedances of 8Ω or greater.

(34) CONTROL ROOM L-R OUTPUTS

These separate Left and Right 1/4” jacks output the line level signals from the Headphone/Control Room (28).

(35) GROUP 1 & 2 OUTPUTS
