1. MIC INPUT
For connecting low impedance dynamic & condenser (self -powered)
microphone through 1/4” plug, either in balanced or unbalanced mode.
Refer to “Plugs Wiring Details” 1a & 1b on page 7 of this manual.
2. LINE INPUT
For connecting signal sources like CD players, Keyboards, etc. through a
6.3mm stereo phone jack, either in balanced or unbalanced mode.
Refers to “Plugs Wiring Details” 2a, 2b, and 3 on page 7 of this manual.
3. CLIP LED
This RED LED lights up to indicate that either the input signal is
overloading the input circuit or the GAIN control setting is high e nough to
distort the signal. Both conditions can be overcome by appropriate
adjustment of GAIN control. Please ensure tha t this LED is NOT
continuously ON.
4. GAIN CONTROL
The input level of both the Mic & Line signals can be adjusted by this
control. It provides a gain range of more than 45dB.
5. BASS CONTROL
It is used to obtain 12dB cut or boost (shelving type) at 100Hz as center
frequency.
6. MID CONTROL
It is used to obtain a 12dB cut or boost (shelving type) at 2kHz as center
frequency.
7. TREBLE CONTROL
It is used to obtain 12dB cut or boost (shelving type) at 10kHz as center
frequency.
8. PAN CONTROL
The signal of mono input channels is distributed into LEFT & RIGHT line
outputs. The PANORAMA (PAN) control is used to adjust the relative
levels of the L & R outputs of this distributed signal.
9. EFFECT CONTROL
For routing the signal to the built-in digital effect processor in desired
proportion.
10. CHANNEL FADER
This slide volume control adjust the level of pre -amplifier mono signal to
panning action.

1. LINE OUPUT
Balanced Line outputs have been provided for the LEFT & RIGHT
channels through individual 6.3mm phone jack sockets. For
making balanced and unbalanced output connections, refer to
‘Plugs Wiring Details” 1c and 1d on page 7 of this manual.
2. SEND OUTPUT
It provides the combined pre-fader output of all the input channels
through a 6.3mm mono phone jack. The pre-fader output is mainly
used for stage monitoring application.
3. RETURN INPUT
It is designed for accepting balanced stereo signal through 6.3mm
stereo phone jack sockets. The Return input signals are directly
mixed with the & R main mix signals so that it is available at LINE
OUTPUT & HEADPHONE OUTPUT.
4. LEFT & RIGHT OUTPUT LEVEL INDICATOR
The output signal level from Left & Right channels is indicated by
an individual 10 segment LED array. Each LED array is calibrated
to display out signal levels varying from -20dB to +15dB. 0dB LED
glows to indicate the rated output level of +4dBu.
5. LEFT MASTER CONTROL
It controls the signal level of the LEFT channel LINE output which
is available through 6.3mm Stereo Phone Jack.
6. RIGHT MASTER CONTROL
It controls the signal level of the RIGHT channel LINE output
which is available through 6.3mm Stereo Phone Jack.
7. EFFECT MASTER CONTROL LEFT CHANNEL
For setting the level of delay signal in the LEFT channel LINE
output signal.
8. EFFECT MASTER CONTROL RIGHT CHANNEL
For setting the level of delay signal in the RIGHT channel LINE
output signal.
9. FEEDBACK CONTROL
For setting the number of repetitions within the selected delay
time.
10. DELAY CONTROL
For setting the delay time within the selected delay time.
11. HEADPHONE OUTPUT
For connecting a stereo headphone through a 6.3mm stereo
phone jack. The headphone output is used for personal monitoring
& its level is not affected by the setting of master control.
12. HEADPHONE CONTROL
It is used for controlling the level of stereo signal which is available
as headphone output.

The Output, Effect & Headphone Section
1. Please ensure that AC mains supply to all the equipments is switched off.
2. Connect the desired number of input sources microphones, CD Player, DVD Player,
keyboard etc. to the appropriate input sockets of the mixer.
3. Connect the power amplifier, external processors, headphone etc. to the appropriate
output sockets of the mixer.
4. All the rotary & slide volume controls of the mixer as well as that of the peripheral
equipments should be set to minimum position.
5. All the tone control (HF, MF & LF), PAN control & BAL controls should be center (FLAT)
position.
6. Keep all the push switch of the mixer in OFF position.
7. Connect all the equipments to their respective AC mains supply sockets.
8. Always switch ON the mixer first and the entire power amplifier in the last. In between,
other equipments can be switched ON.
9. Now, GAIN control setting should be carried out for channels which have microphone
as an input source. The microphone input is designed to accept dynamic & condenser
(self-powered) microphones in both balanced as well unbalanced mode of connection.
10. Press the microphone channel switch to ON.
11. Switch the microphone ON and speak a few words through it while turning up the GAIN
control to a position where the PEAK LED just starts to flicker.
12. Now speak loudly into the microphone and then readjust the GAIN control to a position
where the PEAK LED just flickers.
13. For desired tonal balance, adjust HF, MF & LF controls and then carry out the final
setting of GAIN control as explained in point #12. The setting of tone controls can be
different for each microphone input channel.
14. Similarly, the setting of GAIN control for LINE input channels should be done with
reference to the setting of tone controls & flickering of the PEAK LED.
15. After completing the GAIN setting of all the channels, adjust the slide control of each
channel to obtain the desired mix at the output.
16. For using the built-in digital effect processor, put ON the Effect switch and select the
desired range of delay settings. Obtain the desired echo or reverb effect from delay
control and number of repetitions from feedback control. The leve lof this processed
signal should be adjusted through EFFECT Level control in each channel.
17. The overall level of LEFT & RIGHT LINE output signals should be adjusted through
respective MASTER control.
18. Use PAN control to adjust the level of mono input signal which is contributed to LEFT &
RIGHT channels.
19. The level of pre-fader output of each input channel, that is contributed to the main Send
output.
20. The fader signal, after external processing, are fed back to to the mixer through
RETURN inputs and mixed with the main L & R outputs.
21. Always use interconnecting cables with appropriate connectors which are suitably wired
for proper functioning of the mixer & its peripheral equipments.
