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.

5. MIC INPUTS 1-9
These are mic-level inputs on balanced three-pin XLR connectors. (1:GND 2:HOT 3:COLD)
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.
