INSTALLATION
To ensure years of enjoyment from your NADY AUDIO SPM-6300 powered mixer, please read and understand this manual thoroughly before using the unit.
1. INSPECTION
Your NADY AUDIO SPM-6300 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-6300 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.

CHANNEL SECTION
(1) MIC INPUT
This electronically balanced XLR input is 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) LINE INPUT
This 1/4" input is designed to accept balanced or unbalanced linelevel signals such as those from keyboards, drum machines, or samplers. 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 the Mic or the Line input of a given channel should be connected at one time. Do not connect both at the same time.)
(3) TREBLE EQ
Turn to the right to boost high frequencies, adding crispness too percussion from drum machines, cymbals, and synths. Turn to the left to cut these frequencies, reducing sibilance or hiss. The control has a shelving response providing 15dB of boost or cut at
10kHz.
(4) BASS EQ
This control provides 15dB of boost or cut at 90Hz. Boosting the
Bass control, by turning to the right, can fatten the sound, adding warmth to vocals or extra punch to bass, drums and synths. Turn to the left to reduce stage rumble, hum, or to improve a mushy sound. Cutting the Treble and Bass controls, then pushing up the subsequent volume control is equivalent to a mid range boost.
(5) EFFECT CONTROL
The Effect control adjusts the signal level sent by each channel to the internal Echo Effects DSP (Digital Sound Processor). The
Effect controls are post Channel EQ and the signal level sent to the EFF bus will not be affected by the channel volume settings.
This control also adjusts the level of the un-effected signal sent to the Effect Send (13) output.
(6) MONITOR VOLUME
The Monitor Volume control adjusts the channel signal level sent to the Monitor Master Volume (16) when the Power Amp
Selector Switch (18) is set to Monitor-Main. This control can be adjusted to set the desired monitor mix. The Monitor Volume control is not active when the selector switch is set to Left-Right.
(7) LEFT-RIGHT / MAIN VOLUME
The Left-Right Volume control adjusts the channel signal level sent to the master L-R/Main Volume control (15). This control can be adjusted to set the desired level for the channel in the mix.

FRONT CONTROLS AND CONNECTIONS
MASTER SECTION
(8) POWER ON/OFF SWITCH & LED
This switch turns the unit on and off and the LED indicator will light when the unit is on.
(9) ECHO EFFECT
This control adjusts the feedback/decay time of the internal Echo Effects DSP. Set this control slightly above minimum to emulate room reverbs and adjust towards maximum for hall and stadium decay reverbs.
(10) AUX INPUT
The 1/4" Aux input jack can be used to add line level audio signals to the master mix. This signal level is affected by the Aux/Tape
control (12), L-R/Main Volume (15), Monitor Volume (16) and 5-Band EQ’s (18).
(11) TAPE INPUT
The Left and Right Tape Input RCA jacks allow cassette recorders, CD players, or MP3 players to be added to the master mix output.
These signal levels are affected by the Aux/Tape control (12), L-R/Main Volume (15), Monitor Volume (16) and 5-Band EQ’s (17).
(12) AUX/TAPE VOLUME
This volume control adjusts the signal level in the master mix of the Aux and Tape inputs. It is pre L-R/Main Volume (15), Monitor
Volume (16) and 5-Band EQ’s (17).
(13) EFFECTS SEND & RETURN
The Effect Send 1/4" jack provides a mono mixed signal output from each input channel to an external effects unit, external amplifier, or recording device. The audio mix is adjusted by the EFF control of each channel. The signal output is not effected by the internal reverb. The Effects Return input jack can be used to return the signal into the SPM-6300 or it can be used as another auxiliary input for line level devices. The input signal can be adjusted using the Effects Return Volume (14) and also the output volume of the external device.
(14) EFFECTS RETURN VOLUME
The Effects Return input signal can be adjusted using this control.
(15) LEFT-RIGHT / MAIN MASTER VOLUME
This control sets the level of the stereo left and right signal sent to the left and right Speaker Outputs (19) when the Power Amp
Selector Switch (18) is set to Left-Right. When the selector switch is set to Monitor-Main, this control adjusts the level of the Main
Speaker Output (19).
(16) MONITOR MASTER VOLUME
This control sets the level of the Monitor mix sent to the Monitor Speaker Output (19) when the Power Amp Selector Switch (18) is set to Monitor-Main. This control is not active when the selector switch is set to Left-Right.
(17) STEREO 5-BAND GRAPHIC EQ
The dual 5-band graphic equalizers allow you to adjust the frequency response of the Left-Right outputs, or the Monitor-Main outputs, allowing final tonal adjustments. These provide a maximum of 12dB cut or boost from the flat position for each frequency band; 60Hz/
250Hz/800Hz/2KHz/8KHz. The faders can be adjusted to easily eliminate feedback at the corresponding frequency or audibly color the final mix.
(18) POWER AMP SELECTOR SWITCH
This switch selects which signals are sent to the internal power amps. When Left-Right is selected, the stereo signal from the L-R
Master Volume (15) is sent to separate Left and Right 5-Band EQ’s (17) and then continues to the Left and Right Speaker Outputs
(19). When Monitor-Main is selected, the signal from the Main Master Volume (15) is sent to the Main 5-Band EQ, then to the Main
Speaker Output, and the signal from the Monitor Master Volume (16) is sent to the Monitor 5-Band EQ, then to the Monitor Speaker
Output.

(19) SPEAKER OUTPUT JACKS
The R/Main and L/Monitor outputs are for the Right and Left, or Main and Monitor outputs respectively depending on the Power Amp
Selector Switch (18) setting. The 1/4" speaker outputs can deliver up to 150W RMS per side to 4
Ω loads. Speaker loads less than
4
Ω are not recommended and could result in overheating and damage to the internal amplifiers. If the output audio is noticeably distorted, or sounds like it is turn down the master volume controls immediately to avoid clipping which can damage you speakers and the SPM-6300 power amp with excessive neglect.
If the mixer has been running constantly for several hours, make sure the rear panel is not getting too hot to avoid over-heating the unit and causing thermal runaway. If it is getting very hot, either turn the audio down some or let the SPM-6300 idle with no output signal and the fan on. CAUTION — REAR PANEL CAN GET VERY HOT!! Keep panel away from flammable objects. For maximum cooling, ventilation, and efficiency, keep mixer away from walls or other objects.
(20) POWER CONNECTOR & FUSE COMPARTMENT
The IEC socket is used to connect the power cord to an AC power source. Replace with only the same type fuse as listed in the
SPECIFICATIONS. If it blows continuously, do not use the unit and have it serviced by qualified personnel.
(Caution: Do not remove the center grounding pin.)
(21) AC VOLTAGE SELECTOR SWITCH
Before plugging in the power cord, check to see that the unit is set for the proper voltage for your area: ~115V (60Hz) or ~230V
(50Hz).
