Audac MFA216 Amplifier


Available on back-order

This revolutionary award-winning amplifier is designed as a two-channel amplifier using class D amplifier technology. It can be used for powering low impedance stereo systems with a maximum power of 2 x 80 Watt, while bridging to a constant voltage (100V and 70V) is possible with a maximum output power of 160 Watt. A switch-mode power supply allows a wide variation of main voltages for global compatibility.

The integrated SourceCon™ module* slot allows 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 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). This gain adjustment controls both the sensitivity of the line inputs on the rear as on the front. Thanks to the 2.8” TFT display and the push rotary dial on its front, an unmatched user experience is achieved.

Please pay attention the RCA input is combined with the line input at the back of the device, meaning the rear input is disabled when the front input is in use.

A line out connection at the back of the device is making the device even more versatile. This line out can be used as a preamp output, where the input and volume are the same as the internal amplifier or as a separate secondary stereo zone output, where both zones (inputs, volume control, and many more..) can be operated completely independently of each other.

A priority mute contact on the back of the device mutes the music at the presence of a contact closure between both terminals. Priority enabled on mic-in overrides the muting, allowing emergency announcements or voice messages.

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 MBS1xx 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.

When installed the (optional) ANI44XT Dante™ audio network interface, music from the installed SourceCon™ module or connected line input signal can be shared throughout your Dante™ audio network to other compatible devices or amplifiers. Using Dante™, you can even play priority messages with near-zero latency (100ms) to the audience.

*SourceCon™ modules are optionally available. MFA series does not come pre-installed with one of these modules.

*Automation tool: the MFA series does not have built-in relays, it will only be possible to send commands via AUDAC Touch™ to other TCP-IP products. 2-way communication between devices is not possible.

*NOTE: The powers shown for low impedance stereo mode may look strange to be equal for 4Ω, 8Ω and 16Ω loads, however, these figures are true and correct. The output voltage is increased at higher load impedances to guarantee the maximum output power is achieved. These figures are depending on a correct output setting configuration in the ‘Settings’ > ‘Amplifier’ > ‘Output’ and ‘Output type’ menu.

ANI44XT – Dante™ audio network interface



The operation and configuration of the device can be done in multiple ways. The most obvious way is by using the front panel controls, featuring a rotary selection dial and channel selection buttons with a clear and intuitive user interface on the 2.8” graphical LCD display.

Total system configurations for predefined set solutions can be loaded into the amplifier using the USB port.

Integration of the audio system into home and industrial automation systems is made easy through the RS232 connection & control port whereby functions such as input switching, volume adjustment, etc. can be controlled.

An MWX45 wall panel controller ensures that the installation can manually be operated.

Lastly, the MFA is fully controllable from any device at every time and place through our freely available AUDAC Touch™ 2 application. This out of your pocket application will enable you to control your sources, volume selection, third party equipment and many more from one single dashboard. Resulting in one package solution where you don’t need any automation system to have full controllability from one single dashboard.


Every system comes with different requirements and every customer has his own preferences. Because of this, the structure is made as flexible as possible. This is achieved by an input selection matrix.

Each of the input connections can be patched to any amplifier channel and contains software controllable gain. The different implementations of the in- and output connectors allow the easiest way of connection for every application, while allowing signal link through to other amplifiers.


In our eternal search for ways to increase installer convenience, we’ve introduced a new feature, where the MFA can be updated by the end user. When the MFA is connected to the internet, future updates are automatically pushed to the device. The end-user will be notified of this through the display of the MFA after which the update can easily be performed. This will save the installer the trip to the installation to perform crucial updates.


Optimal protection is not only required for the listeners’ satisfaction but can also be important for complying to the imposed regulations and guaranteeing the lifetime of the equipment. Because of this, protection precautions are implemented in different ways.

Firstly, user access is made possible on different levels. The device can be blocked or accessed in user or administrator level. Different levels allow different configuration and control functions, giving limited (Eg: only volume) control access to standard users and full configuration control to administrators. User restriction can be enabled and disabled and is given through password and/or USB-key.

Secondly, equipment protection is implemented by an output limiter which monitors the output power of every channel and will intervene when the output exceeds a certain level. The corresponding level can be software configured and is indicated in Watts. When the output limiter is configured at the maximum power of the loudspeaker, you can rest assured that the speakers won’t be blown during your absence.

Lastly, the maximum volume for every channel can be set independently. This prevents users (having volume access) going over the limit. This can help you to keep the system compliant with imposed regulations and maintain a good relationship with the neighbours.


The switching mode power supply and Class-D amplifier technology in combination with the auto-standby mode for each separate amplifier channel bring an end to the era of the power-hungry amplifiers. In addition, these features also result in a lightweight amplifier which benefits the customer when used in mobile applications.


The integrated SourceCon™ module allows the implementation of any available compatible module. With lots of different modules to choose from, there’s a wide variety of inputs for every application, creating a true all-in-one solution.

Installation is done by sliding the modules into guide rails, while connections are made using board edge connections. This allows simple and fast installation without requiring additional internal wiring or complex configuration. When inserted to a supporting slot, the module is instantly installed, discovered and ready for operation.


TouchLink™ is an ingenious system that can be used for creating virtual zones by linking multiple TouchLink™ compatible devices with each other. In AUDAC Touch™ 2 you can select multiple devices or amplifier channels that should react to the user as one zone.


To provide this retail setup with an ideal high and low frequency balance, a combination of the CELO8S high-end 8” ceiling subwoofer and 4 CELO2 high end ceiling speaker was opted for. Due to the complete yet comprehensive use of the MFA all in one audio solution, no additional devices are required to make this system a full running one zone solution. As such, the speakers are amplified using the 2 x 80 watt amplification of the MFA, while it receives its input via the SoureCon™ module that can easily been slide into the device. in addition to this, the complete solution can be easily configured through the AUDAC Touch™ application which allows the owners to control the setup from any smart device they want.


In this Corporate environment, we configured the complete solution into three different zones. As it is extremely important that the guests receive a warm welcome the installer in this application chose the ATEO wall loudspeakers which produce warm and detailed sounds. In this way, we find for each zone a different speaker setup that depends on the needs of this zone. By installing a ANI44XT Dante™ audio network interface in both the SMQ350 Wavedynamics™ quad-channel power amplifier and MFA all-in-one audio solution any signal can be shared throughout the Dante™ audio network or different zones in this application. This Dante™ compatibility ensures that the system is very easily expandable when offices are further split up or when departments are added to the current setup.


In order to create an unforgettable dining experience, a qualitative yet complete audio installation from AUDAC has been installed into this Restaurant. The ATEO wall loudspeakers that can be extremely easily installed both horizontally and vertically, provide and warm and detailed sound dispersion in the bar and restaurant area. By connecting the stereo line out of the MFA with the line in of the COM108 and by using the balanced microphone input of the MFA, as an extra line level input, we were able to create an independent 2-zone stereo system. As a result, both zones and inputs can be operated completely independently of each other.
