Operation

l
1. Connect the microphones or line input sources like a CD player or Keyboard to the input jacks. Do not connect
both Mic and Line to any one channel simultaneously. Connect the output jacks to the desired equipment. Refer
APPLICATIONS Section, page # 12, 13.
2. Keep all the rotary control settings of the mixer at '0' position.
3. Keep all the Channel Faders at '0' position and the Left/Right Master Faders at minimum position.
4. Keep all the channel ON/OFF switches and Tape Play Switch at OFF positions.
5. Connect the AC Lead of the mixer to the nearest mains socket and connect the battery lead to car battery for
interruption free operation. Refer Power Supply Section, page # 10.
6. Now switch 'On' the Mixer and the Input Sources.
7. Switch 'On' Channel-1 only, through its Channel On/Off Switch.
8. Connect the Headphones and position the Headphone Gain Control for a comfortable audible level.
9. Increase the Gain Control of Channel-1 only till the Clip LED lights up. Now decrease the gain control so
that the Clip LED just flickers. This is the ideal setting of the gain control.
10. Set the Bass & Treble Controls to the desired levels. Changing the settings of the Bass & Treble Controls may
effect the overall gain. Therefore the Gain Control should be subsequently adjusted to bring the Clip LED to
the correct level.
11. Now move the Slider Fader control of Channel-1 only to position '7'.
12. In case Echo Effect is desired on Channel-1 move the Echo Control of Channel-1 to position '7'.
13. Switch 'On' the Echo Section and set the Echo Section (Delay, Repeat, & Level Controls) for the desired effects.
Refer to the Echo Section for the settings of the Delay, Repeat, & Level Controls, page # 8.
14. Adjust the Pan Control to set the level of the signal in the Left & Right Outputs. Turning the control fully anti-
clockwise will send the signal only to the Left Output of the mixer, and turning it clockwise will send it to the
Right Output.
15. Once Channel-1 is set, do not disturb the control settings of this channel. Then switch 'Off' this channel through
the Channel On/Off Switch.
16. Repeat the above procedure for setting the remaining 8 channels.
17. After all the input channels have been set and switched 'On', the Peak LED of the Echo Section may start
glowing continuously. Reduce the Echo Control level of individual channels and Echo Section simultaneously
so that the Peak LED of the Echo Section goes below the flickering level.
18. After all the channels are set adjust the individual Channel Faders to obtain the desired MIX at the outputs.
19. Now adjust the Master Faders for desired output levels. However take care that the red LEDs of the LED
Bargraph Array do not glow continuously. Refer Output Section, page # 7.
20. For Recording and Playback refer to the Tape Section, page # 9.
