LOGIC CONNECTORS
The RMX
digital
console has the following logic
connections:
• Assignable Logic I/O (three on the KSU
and eight on each 8-Input Expansion card).
• Control Room logic for warning light, ex-
ternal mute, dim, and talkback control.
• Studio logic for warning light, external
mute, dim, and talkback control.
• Cue/Talk/External logic from a remote cue
logic input; a remote timer reset output; an
external location mute, dim and talk com-
mands; and an external talk to CR logic
input.
Page 2-13 has block diagrams for the four types
of logic interfaces. All logic inputs and outputs
are opto-isolated through opto-couplers on their
inputs and solid state relays on their outputs. The
inputs handle logic from +5 to +40 volts. The out-
puts are solid-state “dry-contact relays” that can
switch up to 60 volts, AC or DC.
The CR, Studio and Cue/Talk/Ext. logic con-
nectors are dedicated to the functions that are
shown in the block diagrams. There are no soft
configurations required on these connections.
The Assignable Logic I/O connectors have de-
fault logic functions, as shown throughout this
manual, but the logic inputs have additional func-
tions that can be substituted for the default set-
tings during configuration using VMCC.
An Assignable Logic connector can be “bound”
or associated to an audio connector. On the KSU
Card, audio input A is typically connected to the
Board Operator’s mic preamp and hence does not
have a logic connector associated with it, thus the
three Assignable Logic I/O connectors are labeled:
B, C and D since they are associated with KSU
audio inputs B, C and D. Thus, if audio input B
connects to CD1, CD1’s logic would connect to
the B Logic I/O connector. Likewise, audio inputs
C and D are associated with the C and D Logic
(the RMX
digital
is then automatically synchro-
nized to the VistaMax system’s master clock).
An external AES-3 digital reference signal
(48 kHz, ±100 ppm) can connect to the master
Hub card in a VistaMax frame. Refer to the Vis-
taMax manual (75-52) for details.
AUDIO CONNECTIONS
There are eighteen dedicated analog and digi-
tal outputs on the KSU card (see pg 2-19) for the
bus outputs (PGM 1-PGM 4 and Send), monitor
outputs for the control room and a studio, three
Talkback audio-only outputs, a mono cue output,
and four analog and four digital routable outputs.
There are also four analog and four digital in-
puts on the KSU. The signals on these connectors
are routed to channel strips by session file com-
mands or by “dialing” them up using the Dual
Fader panel source selectors. During console con-
figuration, the inputs can also be made available
to any VistaMax device in the network.
The eight routable outputs can have dedicated
signals routed to them in the init.mac file; by
assigning a signal in a session file; or they can be
assigned as a destination controlled by a VistaMax
source selector.
Each routable connector defaults to stereo link-
ing, but any analog input or output connector can
be set to function as a two mono outputs. See Chap-
ter 4 for more information on stereo versus mono
signals.
Additional audio inputs are available on all
frame sizes, except the RMX
d
-4, by adding one
or more optional 8-Input Expansion Cards. One
8-Input Expansion card can be added to each DSP
Card. The cards have eight audio inputs and eight
logic I/O connections. Card DIP switches set each
audio input as an analog or a digital input. The
eight logic connectors are associated with one of
the audio connections, as detailed in the next sec-
tion.
