Front Panel - the t.amp Proline 1300 Bedienungsanleitung

Front panel:

1.Power switch
When this switch is pushed down, the power on/off transient protection starts working. After 3 to 4
seconds, you can hear "click" once; the amplifier is soft started. After another 1-2 seconds, there will be
another "click", the amplifier is ready to work.
2. CHA input level control
Adjust it to get the volume desired. When you are far away from the speaker, please adjust it according to
the markings on the front panel indicating the amount of attenuation applied to the input signal. Use this
control only when running the amplifier in Bridge mode.
3. CHB input level control
Same as CHA.
4. CHA/CHB peak level indicating LEDs (red)
The LEDs will be on in the two situations:
A. When the output signal has reached its clipping level, the LED lights; possibly resulting in
distortion. Should this occur, adjust the input level control so that the Peak LED turns off.
B. As the signal has been input, the Peak LED lights continuously, but the speaker has no voice, it is
possibly that it is short circuited for loading. You should turn off the amplifier. Find out where the
trouble is and renew operation.
5. Stereo mode indicating LED (green)
This LED will be on when working under Stereo mode.
6. Bridge mode indicating LED (green)
This LED will be on when working under Bridge mode.
7. Parallel mode indicating LED (green)
This LED will be on when working under Parallel mode.
8. CHA/CHB output signal indicating LEDs (green)
This LED will be on when the amplifier is working normally.
9. CHA/CHB protection indicating LEDs (yellow)
The LEDs will be on in the following three conditions:
A. 3-5 seconds after turning on power, or after turning off power, the amplifier is under unstable
status. Indicating the power amplifier is still disconnected from speakers.
B. When the amplifier parts' temperature is over 85°C.
C. When something is wrong with the amplifier.
