Overview

WaveDynamics™ quad-channel power amplifier 4 x 500W

The SMQ series are quad channel 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 provide an enormous flexibility for numerous applications.

The four-channel Class D power amplifier SMA500 offers an output power of 500 watts per channel. The WaveDynamics™ DSP processor in combination with the 2.5” LCD display gives an unmatched user experience with intuitive functions overview for easy configuration. Acoustics can be optimized using Butterworth, Bessel and Linkwitz-Riley filters with selectable rolloff 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 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 an USB flash drive. This ensures the best acoustical performance with a 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.

ANI44XT
The ANI44XT is a Dante audio network interface for installation into WaveDynamicsTM series amplifiers with four input and four output channels. The installation of this optional module allows these amplifiers to be integrated into any Dante enabled AV network and flawlessly transfer digital audio with any compatible product on the market, ranging from music sources to microphone systems, mixers, and many more. A true plug & play solution is created when linking multiple Dante enabled devices with each other on a standard IP network. It offers self-configuring solutions by using DHCP configuration, while the connection can be made to any existing 100 Mbit or 1 Gbit network infrastructure. Bidirectional signal transmissions with a sampling frequency of 48 kHz and a bit depth of 24 bit are simultaneously possible on all in and output channels while guaranteeing an incredibly low latency with a maximum up to 5 ms. (depending on the network occupation). The network connection is implemented using an Ethercon compatible connector, allowing connection using standard RJ45 or ruggedized Ethercon connections in professional applications. The ANI44XT comes delivered as an installation kit, including all required accessories for integration into the amplifier chassis. Installation shall be performed by qualified technicians. The updated ANI44XT will have new functionalities like an updated power supply with much better performance in terms of noise and interference sensitivity and compatibility with the AES67 protocol and TouchLink.

NCP105
The NCP105 is a universal network wall panel controller, which is operated through 4 capacitive touch buttons and a rotary encoder dial. Each button is provided with an RGB indicator LED, while the RGB LED ring gives the user feedback on the selected settings and audio VU information. The front panel is finished with high-grade materials such as hardened glass makes them blend into any environment. These wall panels are compatible with standard EU-style in-wall boxes, these wall panels are the ideal solution for solid and hollow walls. The IP-based communication makes it future-proof while also being backwards compatible with many existing products. In contrast, the limited PoE power consumption makes it compatible with any PoE network-based installation. Each button is provided with a transparent window that allows a custom name tag to be added behind the panel, offering a neat finishing while having a clear overview of the configured functions. The configuration of the button functions and the rotary dial is entirely flexible, with full compatibility and support for a wide variety of devices. The simultaneous multi-device support offers the largest flexibility for numerous specific applications. The NCP105’s design allows it to be used in many applications and with many different AUDAC or third-party AV equipment. From amplifiers to speakers, the choice is yours.
