Overview

Delivering unrivalled sonic purity at affordable prices, the GXA8 can operate in both PCM (up to 24 bit/192kHz) and DSD (Direct Stream Digital) formats. AES/EBU is available as standard but flexible connectivity is ensured by a comprehensive range of optional interfaces including ADAT, MADI and DSD.

The GXA8 employs a DSP free design, precision crystal based phase locked loops, and ultra-low noise and distortion analogue circuitry to deliver unrivalled sonic purity in critical audio recording and production applications.

In standard form, the GXA8 is equipped to convert 8 channels of analogue audio to 8 channels of 24 bit/96kHz digital audio, or to 4 channels of 24 bit/192kHz.

An optional AES expansion card adds 4 extra AES outputs to the 4 supplied as standard, enabling 8 channel 24 bit/192kHz conversion in dual wire mode. The AES expansion card can also act as a distribution amplifier at sample rates below 176.4kHz. At these rates the expansion card duplicates the standard AES outputs and can be used perhaps to feed a backup device.

The addition of an optional DSD output card equips the GXA8 for 8 channel conversion to DSD (Direct Stream Digital).

An optional MADI card enables up to 8 channels of digital data to be injected into a MADI stream.

The MADI card has both coaxial and optical connectors and switches to select the input source and MADI format. Two formats are available,
1. standard format interfaces with any third party device and supports up to 64 channels of 48.0kHz PCM, 32 channels of 96.0kHz PCM or 16 channels of 192kHz PCM.
2. Desono format supports transmission of up to 64 channels of DSD or 64 channels of 24 bit 96kHz over one cable. Desono MADI is supported by all Desono products. 

A miniature rotary switch enables a specific bank of 8 channels of the MADI stream to be selected to carry the data from the GXA8.
