1. INSPECTION
Your NADY AUDIO SPM 6600/8600 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. 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 SPM 6600/8600 on high temperature devices such as power amplifiers, etc., or the unit may overheat in operation.
Although the units 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 noted controls to the positions indicated below to further minimize the chance of undesired noise when first powering up your SPM 6600/8600 :

CONTROLS AND CONNECTIONS
1. MONO INPUT SECTION
(1) P AN CONTROL
(1)
(2)
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 L or R, center-stage, or somewhere in-between.
(2) LEVEL
This adjusts the output level for each channel.
(3)
(4)
(5)
(6)
(7)
(8)
(3) AUX/DSP CONTROL
The AUX/DSP controls are mono and post-EQ and post-fader and the signal level sent to the AUX/DSP bus will be affected 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 AUX/DSP controls the level sent by each channel to the internal DSP (Digital Sound Processor).
(4) MON (MONITOR)
The MON controls the amount of signal to the MONITOR bus and MONITOR OUTPUT (24) control.
(Note: The signal is sent to the MONITOR bus from a location before the LEVEL (2) control of each channel. This means that it will not be affected by the setting of the LEVEL (2) control.)
(5) EQUALIZER CONTROLS
All 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 channel 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!

CONTROLS AND CONNECTIONS
[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.
(6) PAD
This switch attenuates the input signal by -20dB. When connecting a line level device to channels, or if the mic input is distorted, set this switch to the position of -20dB.

(13) (11)
(12)
(7) LINE INPUT
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. 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 should be connected at one time.)
(8) MIC INPUT
The Mic input is an electronically balanced XLR type designed to accept signals from any balanced or unbalanced low impedance (Low Z) microphone. The XLR jack is configured for: Pin1 = ground, Pin2 = positive (+), Pin3 = negative (-).
2. 7-BAND STEREO GRAPHIC EQUALIZER SECTION
(9) L AND R CHANNEL GRAPHIC EQUALIZER
The 7-band channel graphic equalizer allows you to adjust the frequency response of the L and R Channel bus signal, providing a maximum of ±12dB of cut and boost for each frequency band from the flat position. When in BRIDGE MODE, the L-Channel EQ controls the output.
(10) L AND R AMP PROTECT LED
These LEDs will indicate the operation of the protection circuits in the POWER AMP (L and R) section. Shut off unit if this lights during use, and check output connections. Do not operate the unit until this LED is off. If the condition persists, have the unit serviced by qualified personnel.
(Note: This LED will flash when the unit is powered on. This is normal.)
