Model DP569 User’s Manual Front-Panel Menus
4-6
• Pressing any of the preset buttons, immediately invoking a preset, cancels any
pending preset.
• If the unit is in Timecode Control mode, it cannot also recall a preset based
on timecode.
4.2.5 I/O Control
In the I/O Control menu you can set the configuration of the DP569’s inputs and
outputs.
The submenus are:
• Input Channels
• Clock Source
• Input Format
• Output Format
• Timecode Input
• Mono Channel
• Multiplex Mode
• Coding Delay
• Bypass Mode
Input Channels
Allows you to determine the mapping of input sources to audio channels. Channel
assignment is represented in the form A/B C/D E/F, where channels A through F are
mapped to input sources 1 through 6, respectively.
For example, when the Input Channels parameter is set to L/R C/LFE Ls/Rs, the 1/2
input is the source for the Left and Right channels, the 3/4 input is the source for the
Center and Low Frequency Effects channels, and the 5/6 input is the source for the
Left Surround and Right Surround channels.
Clock Source
Specifies the reference clock source for the encoding process as well as the reference
for the output signal. The encoder will not produce a valid output signal if a clock
source is not present. There are three types of clock sources:
• Digital Input: a valid AES3 signal must be present at the Dig In 1/2 input.
• Ref In: a valid AES3 signal must be present at the Ref In input.
• Internal (48, 44.1 or 32 kHz): always valid when selected.
The clock source setting also controls the state of the internal sample rate conversion
(SRC). SRC is disabled for the Digital Input and Ref In – SRC Off settings. SRC is
enabled for the Ref In – SRC On and Internal clock source settings. SRC is required
