Problem No Sound or Sound is too Low

6.0 TROUBLESHOOTING

6.3 Problem: No Sound

Indication: On LEDs not lit

Clip/Output Current Indicators not lit

Check AC plug.

Confirm that AC outlet works by plugging in another device.

Indication: On LEDs lit

Signal LEDs not lit

Make sure the signal source is operating and try another cable.

Check Position of Volume Pots.

Indication: On LEDs lit

Signal LEDs responding to signal level

Check the speaker wiring for breaks.

Try another speaker and cable.

Indication: On LED(s) sequence

The amplifier is in protective muting. Refer to On LED -

flashing sequences table to find out the cause for the mute.

Overheating will cause protective muting.

Check for proper ventilation. If the fan isn’t running the amplifier requires servicing.

6.4 Problem: No Sound or Sound is too Low

Indication: On LED not or sporadically lit

Signal LED off

Clip/Output Current indicator lit green or red

Under Impedance Limiter is active.The load impedance is abnormally low or shorted.

Unplug each speaker one-by-one. If the On LED indicates normally when

you disconnect a cable, that cable or speaker is shorted.

Take care not to use too many speakers in parallel, which would result in -

an impedance that is too low for normal operation!

Indication: On LED(s) Sequence

Please refer to the On LED sequence table to find out which protection is active.

High temperature will cause an attenuation of output level so that under

normal conditions the amp will never mute!

DC will cause the amp to mute or shut down.

Switch off the VORTEX and unplug the source from the amp’s input to prevent DC entering the amp via the signal source. Then switch on the VORTEX. If the On-indicator shows the same sequence, the amp will need to be serviced by a qualified technician.

All other LED sequences that shut down or mute the VORTEX indicate a serious internal fault. At this point, turn the VORTEX off, remove AC power and have the amplifier serviced by a qualified technician.

6.5 Problem: No Channel Separation

Check the mode indicators on the front panel.

Make sure the mode-switch 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.

On the E.U.I., check the Input Signal Parallel Switch is in the stereo-

position.
