Introduction
WaveDynamics™ Class D power amplifiers
The SMA & SMQ series are Class D Power Amplifiers featuring WaveDynamics™ audio processing technology.
They come in different output configurations with two or four channels and are available in output powers of 350
Watt, 500 Watt and 750 Watt. Their great flexibility and different configurations make it the solution for nearly every
system, no matter if it's a fixed installation or a mobile application.

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
a bulletproof protection 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 allow you to create custom
configurations, tweak your setup to the finest detail and adapt to your rooms acoustics. A
delay function allows time alignment of different speakers in your installation.
Configurations also allow you too bridge the outputs, doubling the output power of stereo
channels to one mono channel or make a single three-channel amplifier driving a complete
setup composed of stereo mid/high frequency speakers and a bass cabinet.
Controllability
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 inferface on the 2.5" graphical LCD Display.
Total system configurations for pre-defined set solutions can be loaded into the amplifier
using the USB port.
Dynamic
Integration of the audio system into home and industrial automation systems is made easy
through the RS-232 connection & control port whereby functions such as input switching,
volume adjustment, ... can be controlled.

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.
Input Matrix
Speaker
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.
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 & 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.

Efciency
Lastly, the maximum volume for every channel can be set indepentently. This prevents users
(having volume access) going over the limit. This can help you to keep the system compliant
with imposed regulations and maintain the good relationship with the neighbors.
Efficiency
The switching mode power supply and Class D Amplifier technology in combination with the
auto-standby mode for each separate amplifier channel brings an end to the era of the powerhungry amplifiers. In addition, these features also result in a lightweight amplifier which benefits
the customer when used in mobile applications.
