P 64 Digital Audio Matrix
Owner’s manual
The two left connections of the RELAY OUTPUTS are the READY/FAULT output of the P 64.
This floating output is closed when the P 64 is ready for operation and no error has occurred. It is
possible in IRIS-Net to configure which kind of error causes the contact to be opened. Due to this
feature, this contact is especially suitable for the integration of the P 64 in life safety systems
(closed current principle). An example application for the circuit of a control output is shown in the
following figure. An operating state of the P 64 (e.g. the overstepping of a temperature limit) is
indicated via a pilot light.
Audio Interfaces
Analog audio connecting cable
It is advisable to choose balanced cables (2 signal conductors + shield) with XLR connectors as
analog audio connections. Although all P 64 analog audio inputs and outputs can be used
unbalanced, balanced audio cable is the better choice. A balanced differential audio circuit can
prevent the injection of external noise into the audio path and is strongly recommended,
particularly for long cable runs.
