Input Options
MIDI In/Thru/Out
Standard MIDI In, Thru, and Out connectors are provided at the console’s rear panel
for support of any standard MIDI input device.
The associated MIDI LEDs will light when MIDI data is traveling through the port,
however, the LED merely indicates the presence of MIDI traffic, not that the traffic is
necessarily valid MIDI traffic.
Note: MIDI Out will not output MIDI timecode.
SMPTE Input
A standard female XLR connector is provided at the console’s rear panel for input of
SMPTE timecode. The input is balanced differential with a 10k ohm input impedance.
The XLR connector is wired as follows:
Note: When connecting a single-ended SMPTE source (such as RCA or 1/4" phone
jack), the "hot" lead is connected to XLR Pin 2 and the "ground" is connected to pins 1
and 3. Pins 1 and 3 must be connected together.
The associated SMPTE green LED will be lit when valid SMPTE data is being
received. The LED will flash when either the SMPTE data is not valid or the console
cannot lock in on the signal.
Switch Closure Trigger Input (Virtuoso Console)
The switch closure trigger port is wired to the Board Control [Go] button. Closing the
switch by any compatible device is the equivalent of pressing this button. The
triggering device can be any device that will supply the “short”, such as a hand-held
switch, a relay, a footswitch, etc.
The Virtuoso switch closure trigger
port will accept a Molex® terminal
block which is available from Vari-Lite
(VL Part Number: 52.6567.0001).
