WaveDynamics™ dual-channel power amplifier 2 x 350W
The SMA Series are dual-channel (stereo) power amplifiers providing a new standard for affordable audio amplification in both fixed and mobile audio installations. Their advanced features and availability in different output powers for 350 Watt, 500 Watt, and 750 Watt provide enormous flexibility for numerous applications. The WaveDynamics™ DSP processor in combination with the 2.5” LCD display gives an unmatched user experience with an intuitive functions overview for easy configuration. Acoustics can be optimized using Butterworth, Bessel, and Linkwitz-Riley filters with selectable roll-off which can be configured as Low / High & Band Pass, and the 7-Band equalizer which has adjustable frequencies and Q-factor. Other provided functions are delay and dynamic bass boost. These settings can be custom configured using the front panel of the amplifier, whereby access can be given on two different levels (User & Administrator) using a password or USB-key protection. Loudspeaker protection is provided by an output power limiter whereby the maximum output power for every channel (in Watt) can be configured. Configuration is made simple with loudspeaker presets and full system configurations which can be selected from a library and uploaded with a USB flash drive. This ensures the best acoustical performance with bullet-proof loudspeaker protection. A great input flexibility and source compatibility is provided by the input selection matrix in combination with the XLR and terminal block signal connections. The outputs are made using Speaker and Terminal block connections. System integration is made easy using the RS-232 control port. An optional Dante™ interface is available for the WaveDynamics™ amplifiers. The installation of this network interface allows receiving and sending of low latency, high-quality audio over a standard Ethernet network.

WaveDynamics™ is an audio control and processing technology implemented in AUDAC amplifiers. Thanks to the powerful DSP processor that is built in the amplifiers it can deliver effortless control over the most advanced acoustic configurations.
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 & playing! Besides the optimal acoustic configurations, this library also includes the loudspeaker performance parameters providing bulletproof protection for them.
The operation and configuration of WaveDynamics™ can be done in multiple ways. The most obvious way is by using the front panel controls, featuring a Scroll-Push control™ and channel selection buttons with a clear and intuitive user interface on the 2.5” graphical LCD display.
The 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.
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 links through to other amplifiers.
Optimal protection is not only required for the listener’s satisfaction but can also be important for complying with 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 at the 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 a 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 loudspeakers won’t be blown during your absence.
Lastly, the maximum volume for every channel can be set independently. This prevents users (having volume access) from going over the limit. This can help you to keep the system compliant with imposed regulations and maintain a good relationship with the neighbors.
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 that benefits the customer when used in mobile applications.
|Download all WaveDynamics™ speaker presets|
A complete library of AUDAC Wavedynamics™ loudspeaker (*.SPF) and set solution (*.SOL) presets are available for your projects, making it as easy as picking the right file, loading it & play! Besides the optimal acoustic configurations, this library also includes the loudspeaker performance parameters providing a bulletproof protection for them.
With the set solution presets this even goes further. These files contain parameters for a complete configuration consisting of multiple loudspeakers, such as a combination of loudspeaker cabinets with a bass cabinet. These configuration files contain besides the protection and performance parameters also information about connected channels, bridging, filtering, etc. Additional comments about system configurations are shown on the right side of the browse window. When a *.SOL file is selected, it will be immediately loaded without requiring selection of the channels where it should apply to like with the loudspeaker presets.

All individual files can be found on AUDAC's loudspeakers page under ‘Downloads'.
Any product that is updatable by the AUDAC system manager is automatically discovered and downloaded to your personal computer.
All other software versions can be found via audac.eu/software
No, this is not always needed. When downloading the latest software, it will also include a text file containing the patch notes. If you are not having issues with your current software or do not need the added functions, then you do not need to update the product.
When the user password is lost, it can be changed by logging in with the administrator password. When the administrator password is lost, please contact your local distributor.
This extremely efficient way of controlling your user interface is incorporated in AUDAC wall panels, WaveDynamics™ amplifiers, audio players, and MTX matrixes. It allows an easy and logical way of controlling volume and more advanced settings such as EQ and source selection. The Scroll-Push™ button also provides a design advantage to the front of the device by replacing a large selection of buttons.
