D-75 FAQ |
| Question |
Answer |
|
| I
installed an
SP-75 and all the lights are flashing. Why?
|
The module must be installed in its
dedicated slot, which is just
to the left of the OM-75 module. If the module is installed in any
other normal input slot, all its lights will flash to indicate it is
improperly installed.
|
|
| I
installed an
SP-75 and all the lights are always on no matter what buttons I push.
Why?
|
The module must be installed in its
dedicated slot, which is just
to the left of the OM-75 module. If the module is installed in one of
the utility slots to the right of the SC-75, all its lights will stay
on and it will be unable to respond to any of its buttons.
|
|
| I
added an IN-75
and all the lights are always on no matter what buttons I push. Why?
|
Input modules can be installed in any
of the slots to the left of
the OM-75 module. If the module is installed in one of the utility
slots to the right of the SC-75, all its lights will stay on and it
will be unable to respond to any of its buttons.
|
|
| I
moved my
OM-75/CR-75/SC-75 and all the lights are flashing. Why?
|
These modules must be installed in
their respective dedicated
slots. Because of their unique edge connector configuration there are
only three console slots the modules will fit in. They must be
installed in the proper order in these slots. Starting from the left of
the three slots, the proper module order is OM-75, CR-75, and SC-75. If
any of these modules is installed in the wrong slot its lights will
flash to indicate it is improperly installed.
|
|
| I
have one SP-75
module. Can I have more phone (caller) inputs?
|
The D-75 will only support one SP-75
module, which can handle two
callers. If you need to handle additional callers, please see our white
paper Making
The Connection (pdf).
|
|
| I
can hear my mics
in UTIL even when they’re supposed to be off. Can I change
this?
|
The console comes from the factory
with the UTIL bus configured to
be fed pre-fade and pre-on by all inputs, except the caller inputs.
This feature can be defeated by switching position 4 of the four
position dipswitch on the PR-75 board, found in the console’s
meterbridge area.
|
|
| How
do I increase
the number of mic channels?
|
The D-75 console has an internal four
channel QMP-4 mic preamp
card. Mics are connected by wiring the mic to one of the QMP-4 inputs
and wiring the corresponding QMP-4 output to an IN-75. A second QMP-4
can be added to allow the use of up to eight mics. If additional mics
are needed beyond eight, external mic preamps must be used.

|
| How
do I set up
talkback from the control room to the studio?
|
Any D-75 input can be set up to feed
the internal talkback bus by
turning the channel’s TB TO STU dipswitch on (dipswitches are
located
at the top of the module, underneath the hinged meterbridge). The audio
on this bus interrupts the studio output when the studio TB button on
the console is pressed. A TB level control allows you to adjust the
volume of the talkback signal.
|
|
| How
do I set up
talkback from the studio to the control room?
|
Any D-75 input is put into CUE when
an external user-supplied
switch, connected to pins 17 and 19 of that channel’s DB-25
connector,
is pressed. The operator can then hear that channel’s audio over
the
console CUE system.
|
|
| How
do I talk with
the caller off line?
|
Any D-75 input can be set up to feed
the internal talkback bus by
turning the channel’s TB TO STU dipswitch on (dipswitches are
located
at the top of the module, underneath the hinged meterbridge). The audio
on this bus interrupts the caller 1 feed when the CUE CALLERS 1 button
on the console is pressed and it interrupts the caller 2 feed when the
caller CUE CALLERS 2 button is pressed.
