Audio Inputs and Outputs

The connections of the audio signals to the equipment are made using 50 way multi-way connectors.
One connector is used for 16 inputs and another for 16 outputs. The same type or polarity of
connector is used for inputs and outputs. A larger drawing is included at the end of this section.
Standard D50 pin-out
D50 pin-out for 16x4 dual audio
D50 pin- out for 16x8 dual audio
The mating halves of these connectors are PLUG types and available as options (AK-0006). They are
not supplied as standard because many customers prefer to buy their connectors in bulk and prepare
the cables in advance of the equipment being shipped.
Each connector has three pins for each signal: signal hot (+), signal cold (-) and screen. The same
pattern of wiring is used on all connectors (except Q16-AA-1604 and 1608, see above), i.e. Input 1 is
wired the same as Output 1. All the connectors on the rear of the frames are sockets. It is sound
analogue audio practice not to earth the cable screens at both ends, as sometimes hum can be
introduced owing to earth potential differences. However, with digital audio is better to ground at both
ends.
For unbalanced AES audio, standard video cable and frames with BNC connectors are used.
The 1U and 2U audio frames are used for many different router types and sizes. As such, the rear
panel connectors have different functions and it is important to refer to the following list before
installation.
