Digital Output Format

This sets the format of the channel status block in the digital

output bitstream to be “professional” or “consumer”.

With the professional setting, the digital output bitstream

conforms to AES3-1992 (r1997) amendment 4-1999 (generally

referred to as AES/EBU). With the consumer setting, the

output bitstream conforms to IEC60958 (generally referred to

as S/PDIF). The factory default setting is Consumer.

It is important to appreciate that in the CDR-882 a bitstream

conforming to either AES/EBU and S/PDIF standards is

available simultaneously at all digital outputs, i.e., all three digital

outputs carry the same format at all times.

Setting the Digital Output Format menu option to Professional

or Consumer merely changes the channel status block format

between “professional” and “consumer”, as might be required by

other equipment. There is no difference in the audio part of the

bitstream at the outputs. However, note that only the S/PDIF

consumer format carries CD Text data and Track IDs.

SCMS

The SCMS (Serial Copy Management System) menu option

determines how the SCMS copyright flag is set on the disc being

recorded. There are three settings available for the SCMS flag,

Prohibit Copy, Copy Once or Permit Copies.

With the SCMS set to Prohibit Copy, it will not be possible for

any further digital copies of the disc to be made.

If the option is set to Copy Once, a digital copy of the disc can

be made, but it will not be possible to make any further digital

copies from that copy.

With Permit Copies set, there are no restrictions on making

digital copies of the disc.

Note that it is not possible to change the SCMS setting while

the CDR-882 is in RECORD mode. See page 48 for further

information on SCMS.

Copy Speed

The CDR-882’s DISC COPY function permits CDs to be copied at

high speed. Different media have different optimum write

speeds. This menu option lets the user set a copy speed to

optimise the performance for the disc type in use.

One of three copy speeds may be set, Low, Medium or High.

The factory default setting is Low.

Broadly, Low corresponds to up-to-8x normal speed; Medium

to 12x to 16x normal speed and High to 24x to 52x normal

speed. The precise copy speed will be determined by the speeds

supported by the media and the drives.

Note that if the destination disc is a CD-RW, the setting of this

menu is ignored since CD-RWs have very specific write speed

requirements, which are set automatically.

The Copy Speed setting only applies to DISC COPY mode, not

other recording modes.
