Chapter 2:
Connections
Genlock Reference
These BNC connectors, labeled Genlock In and Genlock Loop, are used to loop a
genlock signal through the unit to establish the timing for its video output signal. The
signal for this input must always be stable, such as the output from a black-burst or
color-bar generator. Do not attempt to use a signal that has not been timebase-
corrected. When a valid signal is connected to the Genlock In input, the video output
of the DPS-475/575 will be genlocked to this signal, and the Genlock LED will be on.
When no external reference is supplied to the genlock input, the unit will operate
using its own internal sync generator. If the Genlock Loop is unused, terminate it with
a 75Ω terminator.
S-Video Output
(on breakout cable)
This 4-pin connector on the Multi-I/O breakout cable provides processed,
synchronized/timebase-corrected S-Video (Y/C) output.
RGB(S) Video Output
(on breakout cable)
These four BNC connectors on the Multi-I/O breakout cable, comprising auxiliary
Red, Green, Blue, and Sync, provide processed, synchronized/
timebase-corrected RGB(S) [RGB with auxiliary sync] video output. If RGB without
auxiliary sync is sufficient, the Aux. Sync connection can be reassigned as an auxiliary
Composite output. If RGB(S) output is not required, these outputs can be
reconfigured to provide a key channel output.
Auxiliary Composite Output (on breakout cable)
The Aux. Sync connection on the Multi-I/O breakout cable, normally used for sync in
RGB(S) [RGB with auxiliary sync] video output, can be reassigned to provide an
auxiliary Composite video output with the Aux Sync/Comp option in the Video Setup
menu.
Key Output (on breakout cable)
The Aux. Sync connection on the Multi-I/O breakout cable, normally used for sync in
RGB(S) [RGB with auxiliary sync] video output, can be reassigned to provide a key
channel output with the Aux Output option in the Video Setup menu.
Audio Connections
The DPS-475AV and DPS-575AV can process 2 stereo pairs of analog, AES/EBU,
Serial Digital (SDI) or DV audio (with the optional DV I/O Module). The audio
inputs can be selected from the front panel or Audio Setup menu, and the operator can
specify which of the stereo channels are to be processed. All of the outputs are active
simultaneously.
Analog Audio Inputs and Outputs
(Terminal Strips)
Two stereo pairs of analog audio input and output are supported, designated Channel
1 and Channel 2 on the rear of the unit. Each is comprised of a left and right
component. Each analog audio input channel can be configured as 600Ω or high-
impedance. Each channel can be configured as balanced or unbalanced.
Two terminal strips (one for channel 1, one for channel 2) provide analog audio
connections. Each terminal strip uses the following pinouts:
