S/Pdif Page - M-Audio Delta 410 Manual

Clicking the button labeled "-10dBV" will snap all eight faders to to a location
twelve increments below the maximum setting, effectively lowering the output
line level by 6dB. This represents a line level that will interface well with
equipment that will not accept the hotter signal. As a general rule of thumb, if
you have the outputs set to the Consumer level and you find that you have to turn
the record or input level on the receiving device down to a very low setting, try
decreasing the output line level to the -10dBV setting and turning up the record
or input level. Sometimes a little experimentation is in order to find the best setup
for your situation.
At any time, the individual faders may be set to vary the output level to a
particular port or ports. You can use the Consumer and -10dBV buttons as a
starting point, or operate independently of them. The faders can be set
incrementally in .5dB steps, of which there are 18. If working in surround sound,
these faders can be used to calibrate speakers for monitoring purposes. If using
the 410 outputs for different purposes, the faders allow you to address multiple
targets individually.

S/PDIF Page

The S/PDIF page of the Delta Control Panel configures the S/PDIF output format
and displays the status of the S/PDIF input. To display this page, click the
"S/PDIF" tab of the Delta Control Panel software.
DIGITAL INPUT: This group box displays the current S/PDIF input status. The
Delta 410's S/PDIF receiver is capable of recognizing a valid input signal versus
an invalid, corrupt or non-present one. When a valid signal is detected at S/PDIF
In, this group box displays "Valid Input Detected." When an invalid signal is
detected or no signal is present, the group box displays "Invalid or Not Present."
Below this message are two 'grayed-out' buttons: "Coax(RCA)" and "Optical."
These are functions of the Delta DiO 2496, another product in the M Audio Delta
line, one with both optical and coaxial S/PDIF inputs. These controls do not
apply to the Delta 410.
DIGITAL OUTPUT FORMAT: Within the "Digital Output Format" group, you choose
the digital audio format of the S/PDIF output. The default setting, "Consumer," is a true
S/PDIF format and is recognized by all consumer devices. The alternate "Professional"
setting is an AES/EBU type data stream, but electrically S/PDIF. This is a work-around
that is recognized by some but not all AES/EBU devices.
For both consumer and professional output formats, the "Advanced" checkbox
will allow you to force a few particular status bits in the outgoing S/PDIF signal.
The advanced option is for expert users only; however, if you decide to go
exploring, change a few bit settings and get lost, you can always select the
"Restore Defaults" button to restore the outgoing status bits to their factory
settings. When "Consumer" and "Advanced" are both selected, the group
"Consumer Format Advanced Settings" will appear. When "Professional" and
