Trouble Shooting

It is essential to study the signal flow chart carefully.

Only in this way can you isolate problems. By following the

signal through input and output jacks, it is possible to

locate the problem. If you are unable to isolate the

problem, contact the D&R Technical Support Department for

advice. If the technical staff is unable to correct the

problem over the phone, D&R will send out a replacement

module the same day. Many problems can be found by logical

thinking and simply replacing socketed integrated circuits.

Removing a Module

Turn off the power supply. Remove the 2 module retaining

screws, which will allow you to carefully withdraw the

module from the console. First lift the fader side of the

module and remove the front flatcable connector (near

fader) and then lift further upwards. Then remove the

second flatcable connector and unplug the 3 pin connector

(from the XLR input). Now extender cables can be connected

(if ordered). The master section can be lifted in the

same way, but we advise that the master section only be

serviced by qualified personal. The patch panel has no

flatcable wiring underneath.
