2.3 INPUT EQUALISATION
The input equalisers on the V1630 should be used whenever the source cable length is greater than 90-
100m. The two input channels (A and B) have independent equalisers, each of which is associated with
two jumpers as shown in the table and the figure below. Jumper combinations other than those shown
should not be used.
Channel A equaliser OFF
Channel A equaliser ON
Channel B equaliser OFF
Channel B equaliser ON
2.4 DA MODE
The V1630 DA has 4 modes op operation, controlled by DART or front panel switches. When the
/ switch is set to
REM LOCAL
modes and two 1:8 modes as follows:
· Aout switch sources the 4 Channel A outputs from either the Channel A input or the Channel B
input.
· Bout switch sources the 4 Channel B outputs from either the Channel A input or the Channel B
input.
The source channel for each of the Aout and Bout switches is indicated by an A or B LED above the
switch. The LEDs indicate the source channel selection in force, set either by DART (Rem/Local =
Rem) or by the Aout and Bout switches (Rem/Local = Local). If the Rem/Local switch is set to Rem,
the settings of the Aout and Bout switches are ignored.
