AUDAC- MFA208 ALL-IN-ONE AUDIO SOLUTION - 2 X 40W @ 4 OHM - 80W @ 70/100V
This revolutionary award-winning amplifier is designed asa 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 40 Watt, while bridging to a constant voltage (100V and 70V) is possible with a maximum output power of 80 Watt.
A switch-mode power supply allows a wide variation of mainvoltages 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 (0dB ~ 50 dB).
This gain adjustment controls both the sensitivity of theline 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 inputis disabled when the front input is in use.
A line out connection at the back of the device is makingthe 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, allowingemergency 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 MBS310 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) ANI44 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 optionally available. MFA series does not come pre-installed with one of these modules.
*MFA series is expected to be compatible with TouchLink™ from January 2021.
*NOTE: The powers shown for low impedance stereo modemay 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 toguarantee 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.

Functionality
WAVEDYNAMICS™
A complete library of AUDAC loudspeaker and set solution presets is available for your projects, making it easy as picking the right file, loading it & play! Besides the optimal acoustic configurations, this library also includes the loudspeaker performance parameters providing bulletproofprotection for them.
The 7-Band fully parametric equalizer with adjustable frequency and Q-factor and Butterworth, Bessel and Linkwitz-Riley filters with selectable roll-off allows you to create custom configurations, tweak your setup to the finest detail and adapt to your room’s acoustics.
A delay function allows time-alignment of different speakers in your installation.
Configurations also allow you to bridge the outputs, double the output power of stereo channels to one mono channel or make a single two-channel amplifier driving a complete setup composed of stereo Mid/High-frequency speakers and a bass cabinet.
Thanks to the powerful DSP processor that is built in it can deliver effortless control over the most advanced acoustic configurations.
CONTROLLABILITY
The operation and configuration of the device can be donein 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 fromone single dashboard.
FLEXIBILITY
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.
UPDATE FLEXIBILITY
In our eternal search for ways to increase installer convenience, we’ve introduced a new feature, where theMFA can be updated by the end user.
When the MFA is connected to the internet, future updatesare automatically pushed to the device.
The end-user will be notified of this through the displayof the MFA after which the update can easily be performed.
This will save the installer the trip to the installationto perform crucial updates.
PROTECTION
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 giventhrough 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 certainlevel.
The corresponding level can be software configured and isindicated 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.
EFFICIENCY
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 lightweightamplifier which benefits the customer when used in mobile applications.
SOURCECON™
The integrated SourceCon™ module allows the implementation of any available compatible module.
With lots ofdifferent modules to choose from, there'sa 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™ COMPATIBLE
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.
