Analogue Line Input (A/D converter) module
The 8C-AD Analogue Line Input Module type PREV039/4/2 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 0dBFS=+5.0dBu to 0dBFS=+24.0dBu, in 0.5dBu 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.
8-channel Analogue Line Output
( D/A converter) module
The 8C-DA Analogue Line Output Module type PREV039/5/1 provides eight electronically-balanced analogue output channels from the ADA 8XR, on eight male XLR connectors.
Output line-up level (gain) is variable for each channel over the range 0dBFS=+5.0dBu to 0dBFS=+24.0dBu, in 0.5dBu steps plus a fine trim.
Control of the output line-up level and trim is via menus which are present in the ADA-8XR Menu System if the Module is fitted.
Pro Tools|HDX compatible interface module
The 8C-PTHDX Pro Tools HDX Compatible interface module provides eight channels of digital audio input and output for the ADA-8XR in a form compatible with Avid Pro Tools|HDX workstations.
The Pro Tools HD interface Module enables the ADA-8XR to replace Avid HD I/O interfaces, providing superior audio performance and additional features.
To the Pro Tools|HDX software, an ADA-8XR fitted with a Pro Tools HDX compatible interface module looks similar to an Avid HD I/O and operates in a similar way, supporting sample rates up to 192kHz.
Pro Tools|HD compatible interface module
The 8C-PTHD Pro Tools HD compatible interface Module provides eight channels of digital audio input and output for the ADA-8XR in a form compatible with Digidesign Pro Tools|HD workstations.
The Pro Tools HD I/O Module enables the ADA-8XR to replace a Digidesign 96 I/O or 192 I/O interface, providing superior audio performance and extra features.
To the Pro Tools|HD software, an ADA-8XR fitted with a Pro Tools HD I/O Module looks similar to a 192 I/O and operates in a similar way, supporting sample rates up to 192kHz.
Pro Tools Mix compatible interface module
The 8C-PT Pro Tools I/O interface module provides eight channels of digital audio input and output for the ADA-8XR in a form compatible with Digidesign Pro Tools 24|MIX workstations.
The Pro Tools I/O Module enables the ADA-8XR to replace Digidesign 888|24 or 882 interfaces, providing superior audio performance and extra features.
To Pro Tools, an ADA-8XR fitted with a Pro Tools I/O Module looks the same as an 888|24 and it can be remote-controlled in the same way.
AES3 Digital I/O 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.
DSD I/O module
The 8C-DSD DSD I/O Module type PREV039/9/1 provides eight channels of ‘Direct Stream Digital’ input and output for the ADA-8XR. The DSD interface format carries an over-sampled one-bit representation of the audio signal as delivered on Super Audio CDs (SACDs).
The DSD I/O Module can transact the DSD data in either SDIF 2 (sometimes known as DSD RAW) or SDIF 3 formats, using coaxial cables via a breakout squid, and optionally in the MAC DSD / SuperMAC format using a CAT5E cable.
When combined with the ADA-8XR’s Analogue Line Input and Output modules, the DSD I/O Module provides eight channels of analogue-to-DSD and DSD-to-analogue conversion. The Module also allows for PCM to DSD and DSD to PCM conversion where a PCM-type I/O Module is fitted, such as an AES3 I/O Module. In this case, PCM synchronous sample rate conversion can also be performed between the PCM input and output for all eight channels.
When used in conjunction with a dedicated workstation I/O Module, such as a Pro Tools HD I/O Module, the DSD I/O Module allows DSD audio sources and destinations to be connected to the workstation directly.
Whilst the DSD format uses a fixed sample rate of 2.8224MHz the ADA-8XR’s DSD I/O Module allows the user to run DSD-connected Paths with any of the ADA-8XR's sample rate and sync options
FireWire I/O 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.
Up to four ADA-8s may be connected on the same FireWire bus allowing up to 32 channels of simultaneous recording and playback.
Each FireWire card caters for 8 simultaneous input and output channels at up to 96kHz sampling rate, or for 4 simultaneous input and outputs channels at 176.4 and 192kHz sampling rates. 8 channel simultaneous input and output applications at sampling rates over 96kHz require two FireWire cards. 16 channel input or 16 channel output applications are also supported at up to 96kHz with two FireWire cards.
For Windows PC (Vista and higher, 32 and 64 bit) applications a driver is supplied with the module, which makes the ADA-8(s) appear as Windows Driver Model and ASIO compliant audio device(s).
For Macintosh OS X applications, the Operating System will automatically recognise the connected ADA-8s and make it available to applications as an OS X Core Audio device.
