Ensemble Designs 6020 Four Channel 24-bit Audio DAC - Manual (Page 18)

In the Ch 3 Menu shown below, set the following parameters:
• Ch 3/4 Mode - set the operating modes for Channels 3 and 4.
Choose from 2-Channel (Ch 3 and 4 will be independent), Stereo (Ch 3/4 will be a
stereo pair) or Quad Tracking (Ch 1-4 will track together.) Note that if you have
set Ch 1/2 to Quad Tracking or the Quad On function is enabled on the Quad
Menu, this selection will default to Quad Tracking.
• Ch 3 Digital Ref - sets the Digital Audio Reference level for channel 3 (in
2-Channel mode). If Ch 3/4 Mode is set to Stereo, adjustment will affect the
stereo pair, or if set to Quad Tracking, adjustment will affect all channels.
• Ch 3 Analog Ref - sets the Analog Audio Reference level from -10dBu to +8dBu (in
0.5dBu steps) for channel 3 only (in 2-Channel mode). If Ch 3/4 Mode is set to
Stereo, adjustment will affect the stereo pair, or if set to Quad Tracking, adjust-
ment will affect all channels.
• Ch 3/4 Emph - sets the emphasis correction mode for these two channels. Off
disables the emphasis correction. On applies 50/15µS deemphasis to the two
channels when the sampling frequency is standard. (Note that deemphasis will not
be applied where frequencies are non-standard.) Auto applies 50/15µS deemphasis
as necessary depending on the AES input emphasis status and sampling frequency.
(Note that deemphasis will not be applied when the channel status indicates the
use of CCITT J.17 emphasis.)
Refer to the description of the Sampling Frequency, Deemphasis, Error and Emph
indicators in the previous Channel 1 section.
