M-Audio 1010LT, 121002

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 FORMATADVANCED 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 data. Different manufacturers’products may interpret these

codes differently and require you to set these bits by "trial-and-error" until proper

operation is achieved.

CONSUMER FORMATADVANCED SETTINGS (Emphasis): This status bit is used to

indicate if pre-emphasis has been applied to the outgoing digital audio signal. The default is

"None" and rarely will any user want to set the value to "50/15uSec" unless the transmitted

audio has been encoded with 50/15uSec pre-emphasis.

PROFESSIONALFORMATADVANCED SETTINGS (Data Type): The user may assign

the outgoing data as audio or non-audio data. Many devices ignore this setting. The

obvious default is "audio," however, choosing “non-audio” is appropriate if you wish to

send an AC3 signal (Dolby Digital 5.1 surround sound) out of the S/PDIF output. Some

software DVD players are capable of this, as well as AC3 or Dolby Digital encoding

software.

PROFESSIONALFORMATADVANCED SETTINGS (Emphasis): The user may choose to

indicate or not indicate if pre-emphasis has been applied to the outgoing digital audio signal.

The default is "None" and rarely will any user want to set the value to "CCITT" or "50/15uSec"

unless the transmitted audio has been encoded with one of those types of pre-emphasis.
