INSTALLATION
To ensure years of enjoyment from your NADY AUDIO MXE-812 mixing console, please read and understand this manual thoroughly before using the unit.
1. INSPECTION
Your NADY AUDIO MXE-812 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
The MXE-812 can be rackmounted with the optional RMK-812 rackmount kit which can be ordered from your dealer or through the
Nady Service Department (see back page).
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. Also, do not place the MXE-812 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.
The MXE-812 is designed to operate with the supplied external power supply unit (PSU). 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, especially when monitoring with headphones.
Set the noted controls to the positions indicated below to further minimize the chance of undesired noise when first powering up your

1. MONO INPUT SECTION
(1) MIC INPUT
The Mic input is an electronically balanced XLR type designed to accept signals from any balanced low impedance (Low Z) microphone. To accommodate condenser microphones, this input is also equipped with +48VDC phantom power globally switchable to all XLR input jacks with the Phantom Power switch (22) on the front panel. Dynamic or ribbon-type microphones do not require phantom powering. It will be necessary to adjust the channel gain with the input Trim control (3) to achieve a nominal operating level. The XLR jack is configured for: Pin1 = ground,
Pin2 = positive (+), Pin3 = negative (-).
[Note: The Mic inputs are more sensitive than the Line inputs.
Also, do not connect mics with the power switched on, as indicated by the Phantom Power On LED (25) 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, mute the Monitor/PA speakers when turning the phantom power on or off.]
(2) LINE INPUT
The Line input is designed to accept balanced or unbalanced linelevel 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 (3) 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.
(Note: Only either 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) TRIM CONTROL
The trim control adjusts the input sensitivity (channel gain) of the mic and line inputs on the mono 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. This wide range eliminates the need for Mic/Line switching. 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 Peak Indicator
LED (7) for that channel lights occasionally.
6
CONTROLS AND CONNECTIONS
(4) EQUALIZER CONTROLS
All mono input channels are fitted 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 frequencies fixed at 12 kHz and 80 Hz respectively. The midrange control has a peaking response at
2.5KHz (Q fixed at 1 octave). The channel EQ is a valuable feature of the mixer as it allows the user to control the tonal characteristics of each instrument separately. For example, boosting the LOW can fatten 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 technique is to use the EQ to subtract from the mix. Cutting the HIGH control can reduce unwanted hiss during multi-track recording, while attenuating the MID or LOW can eliminate feedback in a live performance or clear up a muddy sounding mix. Cutting away the top and bottom, then pushing up the Gain is equivalent to mid range boost!
(7) PEAK LED INDICATOR
The Peak LED illuminates when a channel is going into overload.
It detects the peak level after the EQ and will light at 3 dB before clipping to warn that the signal is approaching overload. You do not want the Peak LED to light except very intermittently during a take or a mix. If it does light persistently, reduce input gain with the TRIM control (3).
(8) CHANNEL GAIN CONTROL
The channel gain controls determine the output signal level to the
Master Mix bus. There is no PFL function on the MXE-812. In order to audition any single channel for proper gain, you can turn off the gain control of all the other channels (fully counterclockwise), and set both the auditioned channel and
Master Mix control (29) to unity gain (0 dB). The LED Output
Meter (21) should read around 0 dB.
[Note: Always reset a channel’s input Gain (or external devices’ output level) after altering the amount of mixer equalization cut or boost applied.]
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.
(5) AUX/EFF SEND CONTROL
The AUX/EFF controls are mono and post-EQ and post-fader and the signal level sent to the AUX/EFFECTS bus will be affacted by the channel fader setting. The AUX configurations is ideal for almost all monitoring purpose: 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. The
EFF controls the adjustment of level sent by each channel to the internal DSP (Digital Sound Processor). (See also Digital Echo
Effects Functions and Operations, page 10)
(6) PAN CONTROL
The Channel Pan positions the output of the channel in the stereo field of the Master Mix. Its constant-power design ensures there are no level discrepancies whether a signal is hard-panned, center-stage, or somewhere in-between.

2. STEREO INPUT SECTION
(13A) L (MONO) LINE INPUT
On stereo input channels 5-8, the 1/4" line inputs are designed for stereo or mono line-level signals such as those from keyboards, drum machines, CD players, tape decks, or samplers. However, these inputs can also be used as standard mono line inputs by connecting the signal to the L (MONO) line in. This signal will be routed equally to the BAL control and the left and right outputs in the same way as the standard line input channels. For the stereo inputs, the mono channel PAN (6) control is replaced by the BAL
(Balance) control. See also BAL CONTROL (14) below.
(13B) R LINE INPUT
When using channels 5-6, 7-8 as stereo input channels, the left signal should be connected to the L input and the right signal to the R input. These signals will be routed to the AUX, EQ and
Channel Gain controls equally and will retain their stereo separation. The AUX, EQ, BAL, and Channel Gain controls all function the same as those on the mono input channels.
When a stereo signal is input to a stereo input channel, these controls will affect the left and right signals equally. The Stereo
Line Inputs jacks are 1/4" TRS balanced phone jacks, Tip = positive (+), Ring = negative (-), Sleeve = ground. The input signals to these jacks can be either balanced or unbalanced.
(4) EQUALIZERS
The stereo channel EQ’s operate in the same manner as those in the mono channels. The left and right signals will be affected equally. A stereo equalizer is generally preferable anyhow to using two mono equalizers when equalizing a stereo signal as it avoids possible discrepancies between the left and right settings.
(5) AUX/EFF SEND
These are the same as for the mono channels. Note that a mono sum is taken from the stereo input.
(14) BAL CONTROL
For a mono input to the L (MONO) input the function of the control is the same as the PAN controls (6) of the mono channels.
However, when a channel is run in stereo, this control functions as a Balance control, determining the relative Balance of the left and right channel signals being sent to the left and right Master Mix buses. For example, with the Balance control turned fully clockwise, only the right portion of the channel’s stereo signal will be routed to the Master Mix.

(18) AUX RETURN CONTROL
The Aux Return jacks are the mono or stereo returns for Aux
Send. If you connect a signal to the Left/Mono Return jack only, the Aux Return will operate in mono and the signal will be routed to the Aux Return Control (18) and then mixed into the left and right Master Mix Stereo Outputs (11). The separate left and right return jacks are provided for use with stereo signals such as those from the output of a stereo effects processor. The left and right return signals will be routed to the Aux Return level control (18) and mixed into the left and right Stereo Out (11), while maintaining stereo separation.
(16) (17) (12)
monitors. Get a pair of headphones and listen in stereo and in reverse stereo, just in case you have any significant hearing discrepancies. Sometimes you might want to narrow the stereo width of a reverb field. To do this you will have to come back on two mono channels to get independent pan for the left and right signals.
(10) AUX SEND
The Aux Send jack is the output for the signal sent from the channel AUX/EFF controls (5). They are 1/4" unbalanced phone jacks wired: Tip = positive (+), Sleeve = ground. Aux Send is post-fader. These signals can be sent to the input of an effects processor, multi-track recorder, or used for any other line-level auxiliary purpose
The Aux Returns are multi-functional. They may be used for returning the outputs of effect units, as Tape Returns from a multitrack recorder, or as extra instrument inputs, especially if your
MIDI keyboard or rack supplies a pre-mixed stereo signal.
Certain stereo effects produce a perceived imbalance between the left and right channel levels. To correct for this you will have to bring your stereo effect back on a stereo channel, which has a
Balance control (14). When applying short left and right delays, the shortest one will always seem loudest. When pitch shifting up and down in wide stereo to thicken a sound, the signal shifted upwards will seem louder than one that goes down. In both cases use the Balance control to compensate. When performing any stereo imaging exercise, don’t just rely on the control room

The output level routed to the Stereo Outputs and REC Outputs is determined ultimately by the setting of the Master Mix Gain
Control (29). The Master Mix (signal on the master bus) is the sum of the signals routed from all the channels and also the inputs from the AUX return bus and the TAPE Input (15). Use the
Tape/Rec to Master switch (24) to route signals from the Tape
Input (15) to the Master Mix Gain Control (29). The level of signal routed to the Master Mix Gain Control (29) from DAT, tape decks, CD players, etc., input to the Tape Input (15) is determined by the setting of the output volume control of the audio device being connected, so care must be taken in adjusting this level so as to achieve proper balance in the final mix and to prevent overload distortion. The 10-stage LED Output Meter (21) displays the Master Mix output level.
