Trouble Shooting Your System

If you experience difficulties when using your dCS 904, the following suggestions may help to resolve the problem.

The unit fails to power up

Ensure there is power available on the mains cable and the unit’s mains switch is On.

Check the rated supply voltage shown on the rear of the unit matches the local supply voltage.

Check that the fuse has not blown - if so, correct any obvious cause then replace the fuse as described in the section “User Changeable Parts”.

Check that the mains cable is pushed fully home into the mains inlet in the rear of the unit.

The audio output is low or absent

Check that all cables are connected correctly and not damaged. Damaged cables are a VERY common source of malfunctions!

Check that the source and destination equipments are switched on and correctly set up.

Check that an audio signal is present on one or both of the inputs.

Ensure “Mute” is not enabled - LED off.

The level trimmers on the rear panel do not change the input level

Ensure the trim tool or screwdriver you are using is narrow enough to reach the adjuster (about 2.5mm or 0.1” diameter) and long enough (at least 12mm or 0.5”).

The trimmer may be at the end of its travel - try turning it several times the other way. It is a 20-turn device.

The Left and Right channels are swapped

Check that the audio input cables are not reversed.

Check that the channels are not swapped elsewhere in the system.

In Dual AES mode, ensure that the AES 1 (or AES 3) output is connected to the input on the destination equipment for the Left channel data (probably labelled AES 1, AES A or Left) and AES 2 (or AES 4) output is connected to the input on the destination equipment for the Right channel data (probably labelled AES 2, AES B or Right). See the manual of the destination equipment for information.
