1. TRIM CONTROLS 1~9

These knobs provide continuous control of pre-amp gain from +14dB to +58dB.

2. SIGNAL INDICATORS 1~9

These LED indicator light when signal source come in.

3. PEAK INDICATORS 1~9

These LED indicators light when the input signal to the associated channel is 3dB below clipping. If the indicator is lit steadily, reduce the channel’s Trim level (1) to avoid distortion.

4. CHANNEL FADERS 1~9

These are the main output level controls for each channel. They provide continuous control of the signal level sent from the associated input channel to the master output buss. Faders of unused channels should be set to fully anticlockwise.

5. AUX INPUT LEVELS (AUX1, AUX2)

These knobs provide continuous control of the levels for signals connected to the rear-panel Aux 1 and Aux 2 inputs.

6. MASTER PEAK INDICATOR

These LED indicators light when the master output signal is 3dB below clipping. If the indicator is lit steadily, reduce the master output level (7), or the levels from the active input channels (4) to avoid distortion.

7. MASTER OUTPUT CONTROL

This is the controller that adjusts the level of the master output which is a mixture of each channel’s signal.

PP-6213

AUDIO PRE AMPLIFIER

8. CHANNEL EQ CONTROLS (3 BAND)

hese knobs provide continuous control of equalization up to 12dB boost and cut. Three bands of

T equalization are: Low : 100Hz, Mid : 1kHz, High : 10kHz

9. PRIORITY CONTROLS (PRIORITY 1, PRIORITY 2)

This is the volume controller for the priority input. When the terminal for the priority is connected to PE-6103(Chime & Siren), locating this controller at more than 12 o’clock direction is recommended.

- First place : Priority input 1, input 2

- Second place : When ducking is on, channel 1, channel 2

- Third place : other channels (channel 3 to 9)

10. MASTER EQ CONTROLS (4 BAND EQUALIZER)

These knobs provide continuous control of equalization up to 12dB boost and cut. Four bands of equalization are: Low : 80Hz, Low-Mid : 400Hz, Hi-Mid : 2kHz, High : 10kHz

11. SUB OUTPUT CONTROLS (SUB1, 2)

Level controller for Sub1 and 2 outputs.

12. POWER SWITCH

Press this switch to turn the unit on, as indicated by the Power LED in the switch. Pressing it again to turn the unit off.

1. MASTER OUTPUT

This is a balanced XLR output jack for connecting to the input of a power amp. (Output level : +4dBm/600Ω)

2. SUB OUTPUTS 1-2

These are unbalanced 1/4? phone jack outputs for connecting the input of a power amp or other audio input. (Output level : +4dBm/600Ω)

3. PRIORITY INPUTS 1-2

These are line level inputs on unbalanced 1/4? phone jacks. When the signal is present at these inputs, all other inputs are muted. The level for these inputs is controlled by the front-panel priority level control (9).

4. AUX INPUTS 1-2

PP-6213

These are line level inputs on unbalanced 1/4? phone jacks. Their level is controlled by the front panel AUX level controls (5). (Input level : -10dBm/20kΩ)

AUDIO PRE AMPLIFIER

5. MIC INPUTS 1-9

hese are mic-level inputs on balanced three-pin XLR connectors. (1:GND, 2:HOT, 3:COLD)

T Their level is controlled by the front panel Trim controls (1). Phantom power is supplied to these inputs with the rear-panel phantom power(+18V) switch (13).

6. AC CONNECTOR AND FUSE HOLDER

Connect the supplied standard AC input cable to this input. The fuse holder below the input contains the AC overload protection fuse. If the fuse has blown out, replace it with a fuse of the same type and rating. If the fuse continues to blow, refer servicing to a qualified service technician.

7. REC OUTPUT

This is the unbalanced output for recording mixed signals the output level is -10dBm/10kΩ.

8. INSERT

This is an unbalanced line-level input and output jack, provided for connecting external devices to the mixer’s outputs. ‘Tip(S)’ for signal output and ‘Ring(R)’ for input.

9. DC INPUT TERMINALS

These terminals are provided for the connection of 24V DC power source, such as the Inter-M PD-6359. Connect a 24V DC battery source to these terminals.

10. STEREO LINE INPUTS 7-9

These are provided as three sets of stereo inputs, for the connection of consumer level input sources.

11. MONO LINE INPUTS 1-6

These are line-level inputs on balanced connectors. These are provided as six mono inputs, for the connection of line-level input sources.

12. PRIORITY SWITCHES

When the priority switches are activated, signals of the associated Mic Inputs 1 and 2 will automatically lower the gain level of the other input channels.

13. PHANTOM POWER SWITCHES

Pressing these switches activates the +18VDC phantom power supply to associated Mic Inputs 1 and 2, for use with condenser mics requiring external power. Push this switch again to turn off the phantom power. ? NOTE : In case the switch is on without the lowest level of input channel and master output, high voltage

may occur by assigning DC +18V suddenly to the mic input which can harm the speakers.
