The high density connectors on the Audio rear panels (Section 7.2) are not standard and would require
custom cabling. Snell have created an Audio breakout board assembly (9128) which gives the user access to
the Analogue or AES data via screw fix headers. The 9128 Audio breakout assembly converts the 64 way
connectors on the rear of the Pyxis to 10 way screw fix headers for ease of wiring. Each 9128 assembly
breaks out up to 72 stereo analogue audio inputs and outputs or up to 144 balanced AES inputs and outputs.
The 9128 Breakout board assembly is supplied as a complete kit of parts as listed below (six digit part
numbers are only included for spares or repairs, contact Snell for prices):

The transition board connects directly onto the 64 Way sockets of the rear panel, the Breakout Panel is a 2U
module mounted in the 19” rack to the rear of the Pyxis frame and the Ribbon Cables connects the two
boards quickly and cleanly. The spacing of the screw fix headers means they are difficult to remove – a
