Relay A output: This isolated relay output may be used to indicate abnormal conditions to external monitoring
apparatus. The default operation is to indicate a Fault Incident. See
Power Inlet: The unit should be connected to a suitable mains electricity supply using an earthed Powercon connection
power lead. The device has a switch mode power supply that is capable of operating with a nominal mains voltage of
100V to 230V, 50/60Hz without re-configuration.
NOTE: The device must be earthed to a suitable power earth; failure to do so may affect performance and/or operation
and will invalidate warranty and could be potentially hazardous.
Auxiliary Port A: The default operation is X = Mute when connected to ⏚ (Ground / 0V) , Y = Sleep when connected to
Ground (0v).
Ethernet Communications Port: The device may be controlled entirely from another controller, typically a Personal
Computer, running an application that is compliant with the ObCom standard such as System Engineer. Connection will
normally be made to the controller via this Ethernet port connector. This port is also used for updating the firmware in
the unit.
Networked Audio Ports: The device has the option for Dante
plate will be fitted.
AES3 Audio Input Connector: For inputting Digital Audio signals. The Input is fully balanced. The Link connector allows
a buffered AES3 signal to be passed on to another device. The connection 'heals over' when the unit is not powered up.
Serial communications Connectors: The device may be controlled via this 'third party interface' using either RS232 or
RS485 protocol at a rate of 38.4k Baud. Only one of these may be used at a time. Please refer to the "Tipi Interface
Specification" document for details on how to use it.
Aux Port C Connector
Relay B output: This isolated relay output may be used to indicate abnormal conditions to external monitoring
apparatus. The default operation is to indicate a Check Incident. See
5V, ⏚ (Ground / 0V): This power output may be used for energising external indicators etc from either the Fault relay
or Check relay for example. This output is not capable of supplying more than 100mA of current.
Hb: The Heartbeat output. This outputs a 1Hz square wave all the time the unit is operating correctly.
Aux Port B Connector: Logic inputs. The default operation is to recall one of the Snapshots 1 thru 5 by applying a
Ground (0v) to one of these pins, either momentarily or permanently.
Analogue Audio Input Connectors: All audio connections are fully balanced.
Loudspeaker Connectors: The amplifier Speakon
and the second loudspeaker to the 2+ and 2- terminals. For Bridged mode, use terminals 1+ and 2+.
