Prism ADA8XR-FW-AES - Audio Processor 8 ch A/D & D/A with FW/AES

The Prism ADA-8XR is a multi-channel AD/DA converter that has modular design enabling it to be configured to suit a wide range of applications. The ADA 8XR can be configured as a 16 channel AD converter, a 16 Channel DA converter or an 8 channel AD/DA converter. It can also be a multi-channel FireWire interface, or an AES/EBU / AES3 / SPDIF Digital to Analogue or Analogue to Digital converter.

This unit is configured as a 8 Channel AD/DA convertor, with the addition of the FireWire and AES I/O module.

FireWire Module

The 8C-FW FireWire I/O Module type PREV039/10/1 provides up to eight channels of digital audio input and output for the ADA-8 or ADA-8XR over a FireWire (also known as IEEE-1394) bus connection.

The FireWire I/O Module enables the ADA-8 to be used as a high quality ‘soundcard’, or I/O interface, for native PC and Macintosh workstation applications. Up to four ADA-8s may be connected on the same FireWire bus allowing up to 32 channels of simultaneous recording and playback.

AES Module

The 8C-AES AES3 I/O Module type PREV039/6/1 provides eight channels of digital audio input and output for the ADA-8XR on four AES3 carriers in each direction. The input and output sections of the module are completely independent – that is, they can be assigned to different Paths with different sample rates, Sync Sources and other options. The AES3 I/O module can be thought of as two modules in one – one input module and one output module.

The module can accommodate extended sample rates (up to 192kHz) in Split96 (two-wire) or high-speed (one-wire) modes, and can output consumer or professional Channel Status. Inputs and outputs may be jumpered to comply with either AES3 or S/PDIF carrier voltage levels and impedances.



The ADA-8XR is the audio industries converter of choice in the most exacting applications in music and sound recording, mastering, broadcast and post-production. Offering the cleanest and most transparent conversion available, the ADA-8XR has found a home in some of the most iconic recording facilities worldwide. Ideal for producers, engineers and songwriters wanting to produce the very best results when recording, tracking & overdubbing, mixing to stereo or surround, mastering and monitoring.

The ADA-8XR is perfect for recording vocal, single instruments, drums or orchestra and is just as much at home providing multiple outputs for external analogue summing. It is in use in the top studios around the world as well as being used in numerous film soundtracks.

Design Philosophy

The ADA-8XR takes the philosophy of the widely-acclaimed Prism Sound converter range a stage further: Now, the goals of ultimate sound quality, unbeatable performance and un-matched versatility have been realised in a modular multi-channel, 24-bit 192kHz-capable format. The ADA-8XR provides A/D and D/A conversion and the essential digital interfaces with a stereo monitor mix output in digital and analogue formats.

Clocking & synchronisation

Unlike most other converter systems, the ADA-8XR is ideal as a master clock for your entire system, whether running from its precision internal reference or from an external source. No external clock source can improve the performance or influence the sound of the ADA-8XR. In addition, the ADA-8XR can run in Pro Tools Loop Sync mode, or lock to AES3, AES11 or Wordclock. The ADA-8XR delivers your recordings with perfect transparency, whatever the setup.
