You will notice that the “Input” radio button is selected here, giving us a set of eight faders
that control input levels. Click the “Output” radio button to access the output faders. Also,
you can click the “Mono” button to control each fader individually, or the “Stereo” button
to control faders in stereo pairs.
At any time, the individual faders may be set to vary the input and output levels of a
particular port or ports. You can use the +4dBu, Consumer, and -10dBVbuttons 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 1010LTinputs or outputs for
other purposes, the faders allow you to address multiple sources and 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 1010LT’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 1010LT.
DIGITALOUTPUTFORMAT: 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 "Advanced" are
both selected, the group "Professional Format Advanced Settings" will appear. These groups
are described below:
CONSUMER FORMAT ADVANCED SETTINGS (Copy Mode): Copy protection, also
known as Serial Copy Management System (SCMS), is written into the S/PDIF subcode, a
reserved part of the S/PDIF digital stream that is independent of the actual audio data being
transmitted. It can be used to inhibit the amount of copies that can be made, or allow for
unlimited copying. Three SCMS modes are available. "Original (Copy Permitted)" indicates
that the source material may be copied by a receiving device. "1st Generation" indicates that
the source material is a first generation copy. Most devices that are capable of recording will
reject material with this SCMS mode set. The final option is "No SCMS" which may be used
to override the other two modes and allow a recording device to successfully record the audio
