## Long description

Audac SMQ750 is a 4.0-channel Class D audio amplifier designed for professional AV installations. Delivering up to 3000 W peak per channel, it supports multi-zone and distributed audio systems while maintaining compact rack-friendly dimensions (482 × 420 × 88 mm) and a weight of 8.4 kg. The unit operates on 230–240 V (50–60 Hz) and offers versatile connectivity with XLR inputs and speaker outputs via XLR and terminal block connections. Integrated WaveDynamics™ DSP with a 2.5” LCD enables on-device configuration of filters, equalization and delay, while password or USB-key protection provides two-level access control for user and administrator settings.
Advantages
The SMQ750 provides flexible channel routing and high peak power in a compact package suitable for fixed and mobile installations. Built-in DSP processing includes Butterworth, Bessel and Linkwitz-Riley filter types with selectable rolloff, a 7-band equalizer with adjustable Q-factor, delay and dynamic bass boost for precise acoustic tuning. Loudspeaker protection through configurable output power limiters and a library of loudspeaker presets simplifies commissioning. Input selection matrix and multiple physical connections ensure compatibility with a wide range of audio sources; optional Dante™ network audio expands integration possibilities.

How to use
Install the SMQ750 in a standard 19-inch rack using the specified rack ears and secure appropriate ventilation around the chassis. Connect input sources to the XLR or terminal block inputs and route speaker outputs to the required speakers using XLR or terminal block outputs. Power the unit from a 230–240 V supply and use the front-panel 2.5" LCD and controls to select input routing, adjust filters, equalization, delay and output limits. For system-level control, connect the RS-232 port or install the optional Dante™ interface for networked audio distribution. Use the two-level access control (User and Administrator) to prevent accidental changes during normal operation.
Usage recommendations
Before finalizing settings, upload or select an appropriate loudspeaker preset from the library and verify speaker protection limits match the loudspeaker power ratings. Allow for proper cooling clearance in the rack, and when using long cable runs prefer balanced XLR connections to reduce interference. Use the DSP filters and 7-band EQ to adapt the system to room acoustics and apply delay to align multiple zones or speaker arrays.
