Audio Mode
Sets the audio bit in the output bitstream as either audio or non-audio (i.e., data).
Default is non-audio.
Timecode Input
Selects either the LTC or VITC inputs as the timecode input.
Mono Channel
Allows you to determine the mapping of a mono input source when in 1/0 mode.
Options are channel 1 of digital input 1/2, channel 2 of digital input 1/2 or the
current center channel.
Multiplex Mode
Allows a second encoded bitstream to be combined with the main output bitstream.
When enabled, an internally encoded Dolby Digital bitstream is multiplexed with
another pre-encoded bitstream supplied by the reference-input signal.
When Multiplex Mode is active, the DP569 overwrites the contents of the channel
selected by the Output Mode.
The following options should be selected in order to enable Multiplex Mode:
• The Reference Input must be selected as the Clock Source.
• Timecode Control must be disabled.
• The Output Mode must be set to either Pro 16-bit Ch 1 or Pro 16-bit Ch 2.
• The bitstream in the Reference Input must have been encoded in the Pro 16-
bit mode, and cannot be present in the same channel selected by the output
format.
Coding Delay
Select Internal to specify the amount of coding delay in milliseconds. If External
mode is selected the delay is determined from the signal applied to the TTL delay
input. This control only affects the coding latency through the DP569, it does not
affect the time stamp values if enabled. The minimum allowable coding delay at
each sample rate is shown in Table 4-2.

Sample Rate Minimum Coding Delay
32 kHz 280 ms
44.1 kHz 204 ms
48 kHz 187 ms
