Features
* 9 MIC/LINE IN, 1 MASTER OUT, 2 AUX OUT, and 1 REC OUTBuilt-in nine microphone, one master out, two sub out for convenient using of this unit and one recording out which isnot influenced by output volume controller.
* 2 AUX IN & 2 PRIORITY INPUTAuxiliary input is built-in so that users can use external sound sources conveniently and the sound source connectedto 2 channels of this priority input is played prior to the other input.
* INDIVIDUAL EQUALIZER PER CHANNEL3-band graphic equalizer controls on each input channel.
* 4-BAND MASTER EQUALIZER4-band graphic equalizer controls on master output.
* PHANTOM POWER FOR CONDENSOR MICROPHONEDesigned to use condenser MIC on channel 1 and 2 and supply voltage is DC +18V.
* DUCKINGDucking function available on channel 1 and 2 enable their sound sources to be broadcasted prior to the others.
Operation
1. Plug in or connect DC terminal to power distributor(IPD-8329) with proper polarity (AC INPUT, DC24V).2. Place all slide volume on the front panel and TRIM volume on minimized. 3. If turn on the power, this unit starts operation.4. When connect CD, deck, or MIC on input, adjust gain input with TRIM volume as signal level of desired channel.5. Adjust input channel volume control for favorable audio mixing and adjust output level with output channel volume
control.6. Adjust EQ volume of each channel with monitoring outputs.

1. TRIM CONTROLThis volume controls gain of incoming signaland its adjustable range is 44dB.
2. SIGNAL INDICATORThis LED indicates that signal has been inputproperly on related channel.
3. PEAK INDICATOR (INPUT CHANNEL)This LED indicates that incoming signal hasbeen overloaded, and it is illuminated before3dB to be clipping.
4. INPUT LEVEL CONTROL (CHANNELFADER)It controls level of input signal per channel.Faders of unused channels should be set totheir lowest points.
5. AUX INPUT CONTROL (AUX1, AUX2)It controls amount of signal which is incomingthrough auxiliary input jack.
6. PEAK INDICATOR (OUTPUT SECTION)If mixed level or master output level per channelis too high, this LED is illuminated before 3dB tobe clipping.
7. MASTER CONTROL (MASTER FADER)This is the master control to adjust mixed signalfrom each input channel.
8. 3-BAND EQUALIZER (INPUT CHANNEL)It has been designed as 3-band equalizer toadjust input signal to much richer sound.(HIGH: 10kHz, MID: 1kHz, LOW: 100Hz)
9. PRIORITY INPUT CONTROL (PRIORITY 1,PRIORITY 2)This controller releases prior input signal thanother input channels.Priority of this unit.- First : PRIORITY 1, or PRIORITY 2 INPUT- Second : CHANNEL 1/2 which ducking
switched on.- Third : inputs of other channels (CH 3~9), AUX
input.
10. 4-BAND EQUALIZER (MASTER SECTION)It has been designed as 4-band equalizer toadjust input signal to much richer sound.(HIGH : 10kHz, MID-HI : 2kHz, MID-LOW :400Hz, LOW : 80Hz)
11. SUB OUT 1, 2 CONTROLThis is sub output control to adjust mixed signalfrom each input channel.
12. POWER SWITCHIf press this switch, then power is supplied andLED is illuminated.
13. PHANTOM POWER INDICATORThis LED indicates phantom supply statue (DC+18V) for condenser MIC.

1. MASTER OUT JACKThis is a balanced XLR output jack for connecting to theinput of power amplifier, its output level is +4dBm/ 600Ω.
2. SUB OUT JACKThese are unbalanced 1/4" PL55 jack for connecting tothe input of power amplifier or other audio inputs, itsoutput level is +4dBm/ 600Ω.
3. PRIORITY INPUT JACKThis input jack is used to output the signal first than otherinputs. If signal is input through this jack, all channels areblocked automatically.
4. AUX INPUT JACKWith this jack, auxiliary equipment can be connected. Itsinput level is -10dBm/20kΩ.
5. MIC INPUT JACKIt connects XLR type of MIC (1:GND, 2:HOT, 3:COLD). Its impedance is 50~600Ω.MIC input connector of CH1 and CH2 is supplied +18Vpower through No.2 and No.3 pins by PHANTOM POWERswitch.
6. AC INPUT & FUSE HOLDERConnect the supplied standard AC input cable to thisunit.The fuse holder below the input contains the ACoverload protection fuse.If the fuse has blown out, replace it with a fuse of sametype and rating.If the fuse continues to blow, refer servicing to qualifiedservice technician.
7. REC OUT JACKAs UNBALANCE output to record mixed signal, its outputlevel is -10dBV/10kΩ.
8. INSERT JACKThis is an unbalanced line-level input.Inserting a connector into the insert jack will disconnectthe output of mixer’s master output buss.
9. DC INPUT & OUTPUT TERMINALThese connectors can be used when battery should usecause of AC power failure, and its DC power is 24V. Youcan use it by connecting with IPD-8329.
10. STEREO LINE INPUT JACKThese jack connect stereo equipment of line level such asCD, tuner, and cassette deck.
11. MONO LINE INPUT JACKThese jack connect mono equipment of line level such asCD, tuner, and cassette deck.
12. DUCKING SWITCHWhen the ducking switches are activated,signal to theassociated MIC inputs 1 and 2 will automatically lower thegain level of the input channels.
13. PHANTOM POWER SWITCHWhen you want to use condenser MIC, if turn on thisswitch, +18V condenser MIC power is supplied on No.2and 3 of XLR jack. Because this power is supplied tomicrophones in parallel, you can connect it to otherdynamic microphones. However, if connect it to othertypes of MIC, be sure about plug wiring to do notunbalanced.
* Note: If turn on this switch when volume controller of inputchannel and mater volume controller is not placedat minimized, impact voltage can be incurredsuddenly to MIC circuit, and it may cause defeats ofspeaker.
