AUDAC SMQ350 - WaveDynamics™ 4 x 350W Quad-Channel Power Amplifier 4-8Ω
DETAILS
The Audac SMQ350 delivers 4 x 350W Class-D amplification with WaveDynamics™ DSP for flexible professional audio installations.
The Audac SMQ350 is a lightweight quad-channel (4-channel) Class-D power amplifier designed for both fixed and mobile audio installations. Its WaveDynamics™ DSP processor and intuitive 2.5” LCD display provide a user-friendly interface for fast and accurate system configuration.
Ideal for schools, conference rooms, houses of worship, retail spaces, and entertainment venues, the SMQ350 offers flexible output power and advanced DSP features. Acoustic optimization is achieved through Butterworth, Bessel, and Linkwitz-Riley filters with selectable roll-off, a 7-band equalizer with adjustable frequencies and Q-factor, delay, and dynamic bass boost. Settings can be configured via the front panel with two access levels (User & Administrator) using password or USB-key protection.
Loudspeaker protection is ensured via configurable output power limiters per channel and USB-loadable presets for optimal system performance. Input selection is highly flexible, combining XLR and terminal block connections with link-through capabilities, while outputs include SpeakON-compatible and terminal block connectors. RS232 integration allows simple control system connectivity, and optional Dante™/AES67 expansion provides low-latency, high-quality audio over Ethernet networks.
Compatible with TouchLink™ and AUDAC Touch™, the SMQ350 allows full WaveDynamics™ control from mobile devices, tablets, or computers. Scroll-Push™ control provides intuitive operation of volume, EQ, and source selection while maintaining a clean front panel design.
