Introduction
Multi-functional SourceCon™ Amplifiers
The MFA series are multi-functional SourceCon™ amplifiers, offering true all-in-one solutions for countless
applications, ranging from small bars & restaurants to medium sized retail stores, corporate installations, sports
facilities and many more. The integrated two-channel amplifier can be used in low impedance stereo systems while
bridging merges the output power to be used in constant voltage 70V/100V distributed audio systems.
This combined with the integrated SourceCon™ module offers the most compact and versatile audio system
including audio source, processing, matrix system and amplification in a single and compact housing.
The amplifier is designed as a two-channel amplifier using class D amplifier technology. It can be used for powering
low impedance stereo systems while bridging to a constant voltage (100V and 70V) public address system is also
possible. A switch mode power supply allows a wide variation of mains voltages for global compatibility.
The integrated SourceCon™ module slot enables the implementation of any available compatible module, offering
a true all-in-one solution. Typical applications are the implementation of an audio streaming module or internet
radio module.
Additionally, a stereo line input allows connection for any kind of external audio sources. A balanced mic/line input
allows connection for an announcement microphone or balanced line level signal with compatibility for condenser
microphones using the integrated phantom power supply (15V). A priority switch overrides the background music
when enabled and compatibility with line-level sources (e.g. voice file players) is guaranteed by wide gain adjustment
(0 dB ~ +50 dB).
Thanks to the 2.8” LCD display and the push rotary dial on its front, an unmatched user experience is achieved.
The MFA series are both RS232, RS485 and TCP/IP controllable allowing implementation with home & industrial
automation systems and peripheral devices. Using the freely available AUDAC Touch™ 2 application, control and
configuration can be done from any portable or non-portable device on any location and at any time.
Desktop installation or mounting in an equipment rack using the MBS3xx series mounting adapters is possible. The
half 19” rackspace enclosure allows single installation in a 10.5” equipment rack, or side-by-side (two devices)
in a 19” equipment rack
