Recording / Playback With a Digital Recorder
A digital recorder can be connected for recording and playback.
※Because there is only one playback signal path, monitoring during recording is not possible.
※The OUTPUT connectors of installed option boards carry the signal that is currently selected
with the INPUT SELECTOR (the source that is currently playing). This signal can be recorded.
However, the SACD playback signal or an SACD/CD signal input via HS-Link will not appear at the OUTPUT
connectors of installed option boards and can therefore not be recorded.

Playback
Perform the following steps.
Use the INPUT SELECTOR to select the program source you want to
record and verify that the source is being reproduced correctly.
This signal is being supplied to the OUTPUT connectors of installed
option boards.
Start the recorder. The source currently heard from the speakers is re-
corded.
The OUTPUT LEVEL setting of the DP-77 has no effect on the record-
ing.
Since the same signal is being supplied at all OUTPUT connectors, you
can record on several recorders simultaneously. (Verify that the sam-
pling frequency is suitable.)
Use the INPUT SELECTOR to select the source (input to which the
recorder is connected). Then set the recorder to the playback con-
dition to listen to the sound.

※The signal supplied to the IN connector of a board normally
does not appear at the OUT connector of the same board.
However, with the Digital Input/Output Board [DIO-OC1], the
signal supplied to the COAXIAL input appears at the
OPTICAL output, and the signal supplied to the OPTICAL
input appears at the COAXIAL output.
＊ In digital recording, the SCMS (Serial Copy Man-
agement System) prevents subsequent digital
recording (for example on a DAT or MD re-
corder) of a signal that has already been
recorded once from a digital source. When the
analog connection is used, signals can be re-
corded as often as desired.
＊ When recording a digital signal onto another
digital recorder, sampling frequency matching
is important. Some recorders check the
sampling frequency of the source. If sampling
frequencies are different, recording is normally
not possible.
●
Sources with a sampling frequency of 96 kHz
cannot be recorded on recorders that are not
compatible with this sampling frequency.
●
Digital recording on MD or CD-R uses a
sampling frequency of 44.1 kHz. Sources with
a sampling frequency of 32 kHz or 48 kHz will
automatically be converted at the recorder
(except for some models).
●
Some DAT recorders automatically check and
adapt to the sampling frequency of the source.
