Audio interfaces
The ASP4816 has been designed and developed to provide highly robust system integration interfaces,
allowing worry-free system hook-up under the most demanding situations.
Inputs and outputs are implemented using advanced electronically balanced or ground sensing topolo-
gies and are fitted with extensive RFI rejection networks. All signal interfaces are also fully protected
against accidental misuse e.g. by the connection of phantom powered cables.
Pin conventions
Signal interfaces are provided on either metal shell locking XLR, TRS Jack or 25 pin D Sub connec-
tors. XLR Pin 1 is connected to the chassis safety ground. XLR Pin 2 is designated as signal positive
and Pin 3 as signal negative.
To unbalance the outputs of the ASP4816 Pin 3 should be connected to Pin 1 at the output of the con-
sole. Similarly, inputs from unbalanced sources should be connected via twin screened cables with the
Pin 3 connection tied to the screen at the unbalanced source.
Screen connections
In order to maintain optimum EMC performance it is important that screens are properly connected at
both ends of cable runs. In this way the electromagnetic shield provided by the equipment chassis and
the cable screens will be optimised to reject interference.
It is recommended that only high quality braided screen cables are used to avoid compromising EMC
performance.
