8.1 A/D Reference
The analog input sensitivity of the AD-converters is referenced to digital
full scale level (0 dBFS). The choices are:
+4.2 dBu (-10 dBV compatible),
+13 dBu , +19 dBu and +24 dBu . As the adaptation is performed in the
analog domain, the ADI-8 DS achieves the highest possible values for
Signal to Noise ratio and distortion in any setting.
8.2 A/D State - Meters
The 8 level meters of the
D/A STATE show the digital value (dBFS) of the input level per chan-
nel. The red LED OVR is lit in half brightness 2 dB before full scale level (-2 dBFS), and full
brightness at 0 dBFS.
8.3 A/D Output
The converted analog input signal is available at the ADAT and AES outputs simultaneously.
When using Patch Mode, one or both of the digital outputs no longer carries the A/D signal, but
a digital input signal (AES or ADAT) instead. The corresponding LED will be off then.
8.4 Patch Mode
Patch Mode controls the direct digital connection
between all I/Os. 8 different modes are available.
Each mode is clearly visualized by 6 LEDs.
Pushing the button repeatedly steps through the
following modes:
Format conversion
1. AES input to ADAT output
2. AES input to AES output
3. ADAT input to ADAT output
4. ADAT input to AES output
Double format conversion, parallel output mode
5. AES input to ADAT and AES output
6. ADAT input to ADAT and AES output
Bi-directional format conversion
7. AES input to ADAT output and ADAT input to AES output
Pass-through mode
8. AES input to AES output and AES input to AES output
Notes:
In modes 1 to 4 AD-conversion is still available on the AES or ADAT output.
In modes 5 to 8 AD-conversion is not available.
In single speed mode, the ADAT output signal is mirrored to the ADAT AUX output, so two
ADAT devices can receive the same signal from the ADI-8 DS. This feature is available in any
mode as long as the unit does not use sample rates higher than 48 kHz.
