FOCUSRITE presentsISA 428/828 A / D card


Optional ADC card (-122DB a-Weighted) with 8 CH (up to 192khz). The formats are supported AES, (both singles and dual wire.) Spdif, Adat, with selectable sampling frequency between 44.1, 48, 88.2, 96, 176.4 and 192khz, (for adat over 48khz, of course, via 2 doors), internal or external word clock and 256x clock, S / N Ratio Best of 121dbfs Weighed-A.

Connections take place via 2 connectors Of-type at 25-Pin and standard LightPipe; For the word clock there are connectors BNC in and Out. According to the selected sampling frequency, you can use the following output combinations simultaneously:

• 48khz or lower:

8 AES + S / PDIF + 2 x 8 ADAT = max. 32 simultaneous outputs

• 96khz

8 AES * + S / PDIF + 8 ADAT = max. 24 simultaneous outputs

• 192khz

8 AES * + S / PDIF +4 ADAT ** = max. 20 simultaneous outputs


NB: Supports both configurations AES Single-wire and split-wire; the Split wire obviously, reduce the maximum number of simultaneous outputs.

** The protocol ADAT SMUXIV Supports sampling frequencies over 96kHz: at 176.4 and at 192kHz only channels are available from the 4. of course, the 8 line outputs can be used simultaneously to all ADAT AES and S outputs / pdif
