6.0 TROUBLESHOOTING

6.6 Problem: Distorted Sound

Indication: On LED lit

Signal LED responding to signal level

Clip/Output Current indicator lit only green

A faulty speaker or a loose connection could cause this. Try another

speaker and check the wiring.

The signal source might be clipping. Keep the VORTEX volume pots at

least halfway up so that the source does not have to be overdriven.

Try changing input sensitivity from 1,4 V to 32 dB or 26 dB at the

Gainswitch.

6.7 Problem: Music Sounds Frequency Filtered

If you have installed an optional filter module on E.U.I check the filter on/off-switch to be in off-position.

6.8 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.

6.9 Problem: Squeals and Feedback

Microphone feedback should be controlled 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.
