Selecting the AES/EBU OUT Playback Clock

When recording, the AES/EBU OUT outputs digital audio at 44.1 kHz. For playback,
however, the AES/EBU OUT can be wordclock locked to an external wordclock source.
If the selected wordclock source is not running at 44.1 kHz, the CDR1000’s built-in
sampling-rate converter converts the 44.1 kHz audio from the CD up or down accord-
ingly. This is useful when CD material needs to be transferred to a digital audio system
in which all digital audio equipment is locked to a common wordclock.
The COAXIAL OUT always outputs digital audio at 44.1 kHz.
The Utility Playback Clock parameter is used to set the AES/EBU OUT playback clock.
1Use the [UTILITY] button to select CLK SEL.
The UTILITY indicator lights up and the Playback Clock setting appears on the display.
2Use the [PREV] and [NEXT] buttons to select the Playback Clock.
3Press and hold the [UTILITY] button, or press another button to cancel Utility.
In the following example, the CDR1000 is used in conjunction with a digital multitrack
recorder and digital mixing console, as the playback source for CD material. Digital
audio is transferred from the CDR1000 to the digital mixing console via an AES/EBU
digital connection. The digital multitrack recorder is the wordclock master, and the dig-
ital mixing console and CDR1000 are wordclock slaves. In order to record from a con-
ventional CD player, the wordclock setup would have to be reconfigured so that the CD
player was the wordclock master and the digital multitrack recorder and digital mixing
console were wordclock slaves. The CDR1000’s ability to lock the AES/EBU OUT to an
external wordclock source, however, eliminates the need to reconfigure the system.
Setting Description
INT AES/EBU OUT wordclock derived internally (xed at 44.1 kHz).
WORD AES/EBU OUT wordclock derived from the WORD CLOCK IN.
AES AES/EBU OUT wordclock derived from the AES/EBU IN. If the input
source is set to COAX, record monitoring is not possible via the AES/EBU
OUT.
COAX AES/EBU OUT wordclock derived from the COAXIAL IN. If the input
source is set to AES/EBU, record monitoring is not possible via the
AES/EBU OUT.
