CDR-882 User Manual Version 1.0www.hhb.co.uk
Input Dither
The CDR-882 adds dither to some input signals to produce 16-
bit samples suitable for recording onto a CD.
Analogue inputs always have dither added to the 24-bit output
from the A-D converters.
If an AES/EBU or S/PDIF input signal has its channel status bits
set to indicate a true 16-bit signal, dither will not be applied, and
the Input Dither option will not be selectable. However, dither
may be applied to 20-bit or 24-bit digital input signals at the
user’s discretion.
The two settings for the Input Dither option are Auto and Off.
The default setting is Auto, thus dither will be automatically
applied to digital input signals with more than 16 bits.
Note that the Input Dither setting cannot be changed while the
CDR-882 is in RECORD mode.
Note also that no dither should be added to encoded bitstreams
such as DTS, Dolby E, Dolby Digital or HDCD as it would destroy
their data formats. Detection of such bitstreams will, in most
cases, be automatic and will ensure that Input Dither is selected
Off. However, there may be situations where the formats are
not automatically detected; in these cases, the user should set
Input Dither to Off manually.
Phones Mix
The Phones Mix menu option allows the user to define how the
headphone monitoring operates when the front panel PHONES
SELECT button is set to “Drive 1 + Drive 2” (see page 14).
Priority can be assigned to one or other of the drives. The signal
from a drive will be the playback audio if the drive is in PLAY
mode, or the currently-selected input signal if the drive is in
RECORD mode, or if the front panel MONITOR button [18] is
pressed.
Four options are available:
Option Phones operation
Priority CD1 If both drives have an active signal, only that from Drive 1
is heard
Priority CD2 If both drives have an active signal, only that from Drive 2
is heard
1+2 The signals from both drives are mixed together
1+2 (-6dB) The signals from the two drives are mixed together, but
reduced in level by 6dB
The factory default setting is 1+2.
Output Mix
The Output Mix menu option allows the user to set the output
mix routed to the rear panel audio outputs. Priority can be
assigned to one or other of the drives. The signal from a drive
will be the playback audio if the drive is in PLAY mode, or the
currently-selected input signal if the drive is in RECORD mode, or
if the front panel MONITOR button [18] is pressed.
Five options are available:
Option Phones operation
Priority CD1 If both drives have an active signal, only that from Drive 1
is heard
Priority CD2
If both drives have an active signal, only that from Drive 2
is heard
1+2 The signals from both drives are mixed together
1+2 (-6dB) The signals from the two drives are mixed together, but
reduced in level by 6dB
As Phones The output sockets will carry the same signal as that at
the front panel headphones socket, as determined by the
PHONES SELECT button and Phones Mix menu setting
The factory default setting is As Phones.
