Ao Line Level Menu; Ao Line Trim Menu; Module Dependent Factory Default Stores; Specifications - Prism Sound ADA-8XR Module Reference

Prism Sound ADA-8XR Multi-channel A/D D/A Converter
The upper left-hand corner of these menus identifies the Module Slot (e.g. 'AO1'), followed by
an abbreviated indicator of the module type, in this case 'Lin' to indicate Line Output.
For more information about the location of these menus within the overall Menu System,
descriptions of the different menu types, key definitions etc. see the Firmware Reference.

4.4.1 AO Line Level menu

AO1 Lin:+18.0dBu
[Set dBu=0dBFS]
The AO Line Level menu is a Per-Channel Selection menu. The output line-up adjustment is
specified in terms of the analogue output amplitude which corresponds to the peak handling
level of the D/A converter (i.e. 0dBFS). The user may adjust the line-up level for each of the
eight channels, over the range 0dBFS=+5.0dBu to 0dBFS=+24.0dBu, in 0.5dBu steps.
NOTE for Pro Tools users: the ADA-8XR nomenclature for analogue line-up varies from that
used by Pro Tools. Refer to section 6 for more details.

4.4.2 AO Line Trim menu

AO1 Lin:+0.00dB
[Set dBu=0dBFS]
The AO Line Trim menu is a Per-Channel Selection menu. The user may finely trim the line-
up level for each of the eight channels by ±0.5dBu in 0.05dBu steps. This control is
supplementary to the AO Line Level menu.

4.5 Module Dependent Factory Default Stores

Several of the Factory Default Stores (which include D/A Paths) depend on the fitment of an
analogue output module of some kind for correct operation (as described in the Firmware
Reference). If no analogue output module is available, loading these Stores results in any
available output module being assigned to the 'analogue output' Path, or no output module
being assigned if there is none available.
