The INM-8 and INDM-8 modules have an additional IFB option. This
option allows each input module to generate an individual mix-minus
output; thus each anchor, each announcer, each host, each guest can have
a dedicated mix-minus feed. An analog IFB out is always available, and
an AES IFB out can be enabled or disabled via VDip software. When the
MXM switch is pushed, the module’s signal will be sent to the mix-minus
bus. Each module with the IFB option will have a summed signal from
mix-minus bus except it own signal.
A momentary TB switch will sent the TB monitor signal to the IFB
output of the module.
On the IN-8, INM-8, and INDM-8 modules the SET switch links to the
SEND controls on the optional CPU-8S module (Chapter 8) to assign the
module’s audio to the SEND outputs. The INDM-8 module is also
equipped with DSP. On this module the SET key also initiates the attention
of the central control module (described in Chapter 14) in the meterbridge
for control of DSP functions. This allows the operator to adjust many audio
parameters for the module, including gain trim, EQ, ducking, and com-
pressor-limiter characteristics. An illuminated green “DSP” LED indi-
cates that some corrections were made for this input signal. .
INDM-8 modules with DSP have ten-segment level and gain-reduc-
tion metering.
Level is set by a Penny & Giles long-throw fader. When the D-8000 is
under external serial control from an automation system, the Fader Null
LEDs show which direction the fader must move for manual override.
Channel ON (red) and OFF (orange) switches are at the bottom of the
module. In addition to being controlled remotely, these can also be
programmed (via VDip program) to perform a variety of functions,
activating control room and studio mutes, external tallies, and timer
restart. The OFF switch’s LED can be controlled by an external source
machine to act as a “ready” indicator.
All audio and control input and output signals are made via two multi-
pin DB-25 connectors mounted in the bottom of the console’s mainframe,
directly underneath each individual module.
Internal Programming Options
There are no internal programming options on the IN-8, INM-8 and
INDM-8 modules.
VDip Programming Options
Mutes, timer restart, cue dropout, local/ready, tallies, talkback to
control room, superphone output assign, utility bus pre-fader, remote on/
off-constant vs. pulse, and remote start/stop-normal vs. EFS programming
are made via Virtual Dip Switch Software (see Chapter 9).
