POWER Switch
Push the top part of the knob (marked l)to switch the
amplifier ON. Push the bottom part of the knob
(marked 0) to switch the amplifier OFF.
2.
Volume Control for Channel A
It is used in Stereo/Mono mode, for adjusting the
volume level of channel A.
3.
CLIP Level Indicator LEDs for Channel A & B
One separate red LED provided for each channel.
Continuous glow of LEDs indicates that there is
excessive signal being fed to the input of the
amplifier resulting in clipped and distorted output
levels. In such cases, it is advisable to reduce the
input signal or reduce the volume setting.
Otherwise, the amplifier may go into protect mode
and signal will mute.
4.
Power LED ON/FAULT
This LED glows green when the amplifier is
switched ON. This LED will glow orange if amplifier
is in fault conditioning against over voltage cut off
and DC fuse blown OFF.
5.
Signal Indicator LEDs for Channel A & B
Indicate the presence of signal in channel A and B
respectively.
6.
Volume Control for Channel B
It is used in Stereo/Mono mode for adjusting the
volume level of channel B.

Temperature Indicator LEDs for Channel A & B
Separate yellow LEDs provided for each of the two
channels A & B. Glowing of these LEDs indicates
excessive temperature of the output devices or
transformer. The special circuitry then mutes the
input signals. The amplifier will remain at mute
status, till the devices cool down to normal
temperature. Switch OFF the amplifier to cool down
and then switch ON to continue.
8.
Protect Indicator LEDs for Channel A & B
Separate orange LED provided for each of the two
channels A & B. These LED's glow when the output
is shorted or the output is overloaded or the input is
too high or DC voltage is present on the speaker
output. In any of these conditions the amplifier goes
to protect mode. To reset the amplifier, switch OFF
the amplifier, turn volume control to zero, correct
the fault, and switch ON the amplifier after 5-10
seconds. Increase the volume control slowly to the
desired output below Clip level.
