4.2 Digital outputs
If you are using digital outputs, check whether the devices connected to terminals A1 to A4
are receiving the volume corrector signals.
If this is not the case, then check:
•
the output settings of the volume corrector according to its operating manual and the
details in Chapter 0.
•
by how far the technical data for the outputs (Chapter B) match the connected device.
•
whether all specifications regarding cables and cable lengths in Chapter 0 have bee
fulfilled.
•
whether the signal inversion of the outputs may possibly be incorrectly set (see
above).
•
The transfer of an HF signal via output "DA2" functions with an EK260 with a date of
manufacture from July 2004 onwards.
Signal inversion
With the aid of the jumper "ST4" (
→
Fig. 3, page 8) you can set whether the output signals
are inverted with respect to those supplied by the volume corrector.
•
Position "non-inv." The signals are not inverted (standard setting).
•
Position "inv."
The signals are inverted.
"Inverted" signifies that the FE260 output is switched through (conducts) when the volume
corrector output blocks and vice versa.
