88 Series Outboard / 8801 Issue 7.3
input sampling rate.
In this situation AES out carries the odd and even samples of the audio
double rate signal on its left and right digital channels respectively.
DSD
Selecting DSD will default to 44.1kHz reference. If no sync is available it will
use its own internal clock.
The DSD output is switchable between SDIF 2 and SDIF 3 with a rear panel
switch.
SDIF2 DSD data requires an external sync clock which is passed to the Digital
to Analogue converter of the receiver.
Preferably use the 8801 Wordclock O/P clock which is available on the back of
the 8801 ADC option.
SDIF3 DSD data have embedded clocks and don't require any external sync
clock.
NB: Please refer to your DSD recording device for compatibility information.
Headroom
The unit can be set to one of three headroom settings; +14dB, +18dB or
+22dB, relative to +4dBu.
The headroom is the number of dBs above +4dBu before the ADC clips.
The Digital O/P button will illuminate red if the selected input level is
exceeded for more than 1 sample.
The headroom can be changed by accessing the switches on the back of the
ADC optional board.
75 Ohm WCLK
Selects a 75 Ohms input impedance for WCLK in.
Installation procedure
The Neve 8801 ADC board must only be installed by an authorised Neve
