PMQ240 WaveDynamics™ quad-channel 100V power amplifier


The PMQ series are professional 100V quad channel power amplifiers, providing a new standard for premium sound 100V amplification in public address applications. Their advanced features and availability in different output powers provide an enormous flexibility for numerous applications. 

The PMQ240 is a four channel Class-D 100V power amplifier with an output power of 240 Watt for each channel. The WaveDynamics™ DSP processor combination with the 2.5” LCD display gives an unmatched user experience with intuitive functions overview for easy configuration. 

Acoustics can be optimized using the filters selectable between Low / High & Band Pass and the 7-Band equalizer both with 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 password or USB-key protection. 

Configuration is made simple by the 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 a ‘bullet-proof’ loudspeaker protection. 

A great input flexibility and source compatibility is offered by the input selection matrix and the XLR and terminal block signal connections. System integration is made easy using the RS-232 control port. 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.

Total control of your audio system

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 & play! Besides the optimal acoustic configurations, this library also includes the loudspeaker performance parameters providing a 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 link through to other amplifiers.


Optimal protection is not only required for the listener’s 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 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 brings 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.

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.
