USER MANUAL
TECTON POWER AMP SERIES P.22
6. Problem: No Sound
Indication:
Signal LEDs not lit
Clip LEDs not lit
Check AC plug.
Confirm that AC outlet works by plugging in another device.
Indication:
Output Current LEDs are lit
Signal LEDs not lit
Make sure the signal source is operating and try another cable.
Check position of volume pots.
Indication:
Output Current LEDs are lit
Signal LEDs responding to signal level
Check the speaker wiring for breaks.
Try another speaker and cable.
Indication:
Signal LEDs show red (Protect Mode)
Overheating will cause protective muting. Check for proper ventilation.
If the fan isn’t running the amplifier requires servicing.
6.2 Problem: No Channel Separation
Check the mode indicators on the front panel and make sure the mode
selector on the rear panel is in the stereo-position.
Make sure other equipment in the signal path such as mixers and preamps
are set for stereo, not mono.
6.3 Problem: Distorted Sound
Indication:
Output Current LEDs are lit
Signal LEDs responding to signal level
Clip LEDs not lit
A faulty speaker or a loose connection could cause this. Check the wiring
and try another speaker.
The signal source might be clipping. Keep the TECTON volume pots at
least halfway up so that the source does not have to be overdriven.
Keep the TECTON volume pots at least halfway up and try changing input
sensitivity from ,4 V to 32 dB or 26 dB with the gain selector on the rear.
6.4 Problem: Hiss
Unplug the amplifier input to confirm that the hiss is coming from the
source or from a device upstream. Erratic or popping noises indicate an
electronic fault in the offending unit.
To keep the noise floor low, operate the primary signal source at full level,
without clipping.
Avoid boosting the signal further between the source and the amplifier.
6.5 Problem: Squeals and Feedback
Microphone feedback should be eliminated with mixer controls. If noise
continues to build up with no microphone gain, there is a serious fault
in the signal processors or cables. Working in succession from the signal
source towards the amplifier and check each device in the signal path by
reducing its gain or by unplugging it.
