Prism Sound 8C-AD 8-Channel A/D Module for ADA-8XR Interface
8-channel analog to digital module for the Prism Sound ADA8XR
The Prism Sound 8C-AD 8-Channel A/D Module provides eight electronically-balanced analogue input channels to the ADA 8XR, on eight female XLR connectors.
Input line-up level (sensitivity) is variable for each channel over the range 0 dBFS=+5.0 dBu to 0 dBFS= +24 dBu, in 0.5 dBu steps plus a fine trim.
Each channel has a Prism Sound Overkiller progressive limiter capability, which prevents the A/D converter from reaching full-scale, even when the input level significantly exceeds the selected input range. More information about the Prism Sound Overkiller can be found in the Technical Background section of the Operation Manual.
Control of the input line-up level and trim, and of the Overkillers, is via menus which are present in the ADA-8XR Menu System if the Module is fitted.
