The interface unit shall be designed for digital audio mixing applications and be optimised for use in live performance. It shall feature 8 integrated microphone preamplifier inputs with 2.5 dB analogue gain steps, 8 servo-balanced electronic outputs and a digital audio interface with 8 input channels and 8 output channels, each configured as four digital data streams, which shall be compliant with the Audio Engineering Society AES3-2009 standard. All connections shall be on industry-standard XLR connectors and the interface unit shall be capable of operating at 48 kHz and 96 kHz sampling rates.
The interface unit digital audio interface shall incorporate sample rate conversion for the both inputs and outputs and shall be capable of interfacing to equipment operating at 48 kHz and 96 kHz. The interface unit digital audio interface shall feature external clock synchronisation for input channels and word length and clock source options (internal 48 kHz, internal 96 kHz or external synchronisation) for output channels.
