Rear panel description
1) AC Power inlet:
The mains power supply (100-240V AC - 50/60 Hz) has to be applied to this AC power inlet. The connection is
made by an IEC C14 power connector.
2) RS232 / RS485 connector:
The RS232 and RS485 connectors allow integration of the MFA in an automation system. This interface can also
be used for connection of optional wall panels (MWX45).
3) Priority mute contact:
A priority mute contact mutes the amplified output at the presence of a contact closure between both terminals.
Priority enabled on MIC IN overrides the muting, allowing emergency announcements or voice messages. This is a
Normal Open (NO) contact, which means priority muting is enabled when the contact is closed.
4) Loudspeaker output connections:
Output connections for both stereo low impedance and mono constant voltage distributed audio systems are
implemented using a 4-pin terminal block connection. More information about loudspeaker output connections is
described in the ‘connecting the system’ chapter.
5) Ethernet RJ45 Connector:
The MFA is connected to an Ethernet network through this connection. It allows control of the system and its installed
modules from any Ethernet supported device. Various possibilities of Ethernet control are available, including sending
commands over TCP/IP and full system control using the AUDAC Touch™ 2 application.
6) Dante® module connection (optional):
The MFA amplifier can be expanded with an optional ANI44 DANTE module. Using this module, bi-directional
network based audio transfer using the Dante® protocol is made possible. The direct inputs (microphone and line
or SourceCon™ module input) are also transmitted over Dante®, allowing to receive these inputs on other Dante®
compatible devices in your network as well. The line / SourceCon™ module inputs are linked with Dante channels
3&4 (stereo) while microphone in is linked with Dante channels 1+2 (mono). (See block diagram)
7) Line out:
An unbalanced line-level output is available. This output is configurable as a pre-amp output (following the same
source and volume as the internal amplifier) or as a secondary zone output (with individual input selection and volume
regulation). When configured as a secondary zone output, a two zone system can be achieved. When configured as
a secondary zone output, only the same selection between line and SourceCon™ module can be made as on the
primary (amplified) output (see block diagram for clarification). Other inputs (e.g. Dante®) are free to be chosen.
