MIDI I/O Ports
These MIDI In and Out Ports provide 16 channels of MIDI in-
put and 16 channels of MIDI output to D-Show. The MIDI I/O
ports are used in sending and receiving Snapshot MIDI mes-
sages, and in receiving MIDI Time Code from external devices.
Com Mic, Gain Control, and Phantom Power
This Com Mic connector and controls allow connection and
control of an intercom system. The Gain control operates in
steps of 3 dB. Phantom power may be applied to the Com mic
with the Mic Power switch.
Monitor Outputs
These 2 Monitor Outputs are used for output to the near-field
monitoring system. These are 1/4-inch balanced TRS connec-
tors.
2-Track Analog Inputs and Outputs
These 2-Track analog connections are used for input and out-
put of analog audio material, which can be routed to the Main
bus. These are balanced 1/4-inch TRS connectors.
2-Track Digital Inputs and Outputs
These 2-Track digital connections are used for input and out-
put of digital audio material, which can be routed to the Main
bus. Stereo AES/EBU or S/PDIF I/O connectors are selectable
with the AES–SPDIF switch. These connectors support 24-bit,
48 kHz digital signals. Input signals with other sample rates
are sample-rate converted to 48 kHz.
Analog Inputs and Outputs (1–8)
These 8 pairs of analog inputs and outputs are used for hard-
ware inserts, or for input and output of program material from
the front of house position. These are balanced, 1/4-inch TRS
connectors.
