Troubleshooting

Situation	Indication	Action
No Sound	Signal LED not lit	Check AC plug. Confirm that AC outlet works by plugging
	Clip LEDs not lit	in another device.
	Output Current LEDs are lit	Make sure the signal source is operating and try another
	Signal LED not lit	cable. Check position of Volume Pots.
	Output Current LEDs are lit	Check the speaker wiring for breaks.
	Signal LEDs responding to signal level	Try another speaker and cable.
	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.
No Channel	No Channel Separation	Check the mode indicators on the front panel and make
Separation		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
Distorted Sound	Power LED is lit	A faulty speaker or a loose connection could cause this.
		Check the wiring and try another speaker.
	Signal LEDs responding to signal level	The signal source might be clipping. Keep the volume
		pots at least halfway up so that the source does not have
		to be overdriven.
	Clip LEDs not lit	Keep the volume pots at least halfway up and try
		changing input sensitivity from 1,4 V to 32 dB or 26 dB
		with the gain selector on the rear.
Hiss	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.
Squeals and	Squeals and Feedback	Microphone feedback should be eliminated with mixer
Feedback		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.
Protea	Comm LED lit	Check connection between computer and any routers or
Communications		switched in the network. Reboot computer. If issue is not
Failure		resolved, consider replacing CAT-5 Cables
	Comm LED not lit	Check connection between amplifier and network. Reboot
		computer. If issue is not resolved, consider replacing
		CAT-5 Cables
