## Long description

The AUDAC SMQ500 audio amplifier 4.0 channels Black Class D is a quad-channel Class D power amplifier designed for professional fixed and mobile audio installations. It combines compact dimensions with a set of DSP-driven tuning tools and robust protection mechanisms to deliver reliable, low-distortion amplification. The amplifier offers four output channels, low total harmonic distortion (0.05%) and flexible input/output connectivity suitable for a wide range of sound reinforcement, commercial and installed-audio applications.
Advantages
The unit provides high audio fidelity with minimal harmonic distortion and configurable output power limiting per channel for loudspeaker protection. Integrated WaveDynamics™ DSP with a 2.5” LCD display enables on-unit configuration of crossover filters (Butterworth, Bessel, Linkwitz-Riley), selectable rolloff, a 7-band equalizer with adjustable Q, delay and dynamic bass boost. Multiple input types and a selection matrix increase source compatibility, while thermal, overload and short-circuit protection ensure operational safety in demanding environments.
Suitable for (tasks / use cases)
 Small to medium venue sound reinforcement
 Fixed commercial audio installations (retail, hospitality, corporate)
 Portable or mobile PA systems and rental setups
 Multi-zone or distributed audio systems requiring quad-channel amplification

How to use
Install the amplifier in a suitable rack or stable surface, ensuring adequate ventilation to avoid overheating. Connect source devices to the chosen inputs (XLR or terminal block) and route speaker outputs to the appropriate channels using speaker terminals or the terminal block. Use the front-panel WaveDynamics™ interface and 2.5” LCD to select input routing, apply crossover and equalization settings, set delay and dynamic bass boost, and configure per-channel power limits. For multi-unit setups or remote control integrate via the RS-232 port, or add the optional Dante™ interface for networked audio distribution. Always verify speaker impedance compatibility and start with conservative gain settings before increasing level.
Usage recommendations
Allow sufficient airflow around the amplifier, avoid stacking heat-generating equipment directly above it, and use the built-in protection and power limiter settings to protect loudspeakers. Save preferred loudspeaker presets and system configurations to a USB flash drive for quick deployment and reproducible setups.
