OPERATING INSTRUCTIONS – CA 4588 Digital / Analogue Interface
The CA 4588 Digital / Analogue Interface extends the MCS-D conference system with audio inputs and
outputs. The CA 4588 is provided with 3 interface units each with 2 audio inputs (analogue) and 2 audio
outputs (analogue and digital).
You can connect external devices such as wireless microphones or reproducers to the inputs, and to the
outputs you can connect external devices such as recorders, mixing consoles or amplifiers.
The CA 4588 Digital / Analogue Interface is powered via the NetRateBus conference sockets and auto-
matically recognised by the system when connected to the control unit.
The interface units and audio channels are configured via the MCS-D 200 control unit or the iCNS
conference software.

Connectors and Indicators
Front view
Voltage Monitor LED
LED illuminates green to indicate the normal operation status
LED is flashing red to indicate that the supply voltage at the NetRateBus sockets is too low
Identification LED
LED illuminates green to indicate which of the interface units (1-3) of the CA 4588 is currently
configured

AES/EBU Out
The AES/EBU connection provides two digital channels according to the AES3 or EBU Tech-3250E
Standard. The configurable audio channels (CH1 and CH2) are transmitted via these XLR sockets
with a fixed level and a sample rate of 48 kHz.
Analogue inputs and outputs
Two balanced analogue inputs for line level (6 dBu nominal) and two analogue outputs with line
level (6dBu maximal). The signals are transmitted via a 12-pin Phoenix connector.
NetRateBus sockets for conference bus to connect to the control unit e.g. MCS-D 200
