## Long description

The AUDAC SMQ350 is a compact Class D audio amplifier designed for professional installations where clean power and flexible signal routing are required. Delivering low distortion (0.05% THD) and a high signal-to-noise ratio (95 dB), this quad-channel amplifier balances efficiency and audio fidelity. It offers both XLR and terminal block inputs, speaker and terminal block outputs, an intuitive WaveDynamics™ DSP with a 2.5" LCD for on-device configuration, and robust protection features for reliable operation in fixed and mobile setups.
Advantages
The amplifier combines Class D efficiency with high audio quality, providing low distortion and a wide dynamic range suitable for stage and performance environments. Its WaveDynamics™ DSP includes selectable Butterworth, Bessel and Linkwitz-Riley crossover filters, a 7-band parametric equalizer with adjustable Q, delay, and dynamic bass boost for precise acoustic tuning. User and administrator access levels, password or USB-key protection, and configurable output power limiting enhance loudspeaker protection and system security. Multiple input/output connection options and RS-232 control facilitate integration into existing AV systems.
Suitable for
Live sound reinforcement for small to medium venues
Installed audio in houses of worship, auditoriums, and conference rooms
Portable PA systems and touring rigs requiring compact, multi-channel amplification
AV systems that require DSP-based tuning and remote control

How to use
Install the SMQ350 in a suitable rack or location with adequate ventilation and secure speaker connections to the speaker outputs or terminal block. Connect source devices using XLR or terminal block inputs and configure input routing with the input selection matrix. Use the front-panel 2.5" LCD and WaveDynamics™ DSP to select crossovers, adjust the 7-band EQ, set delay per channel, and enable dynamic bass boost as required. Protect speakers by setting the output power limiter values for each channel and store speaker presets or full system configurations to a USB flash drive for easy recall. Use RS-232 or the optional Dante interface for remote control and networked audio distribution when available.
Usage recommendations
For consistent performance, verify speaker impedance and sensitivity before configuring output limits, start with conservative limiter settings, and use the built-in DSP presets as a baseline. Allow adequate rack ventilation for Class D operation and keep signal cables separate from power cabling to minimize interference. When integrating with networked audio, use a dedicated VLAN for Dante traffic and follow manufacturer guidelines for latency and clocking.
