SoundTube Entertainment MA3501t Overview

The MA3501t Mono-Block 350W Audio Distribution Amplifier from SoundTube Entertainment is a high-output, low-voltage mono power amplifier engineered for use in distributed sound applications. Designed for use with SoundTube and other high-fidelity speakers, the amplifier provides 350W of output power into 4 Ohms and 225W into 8 Ohms. It offers taps for 25V, 70V, 100V, and bypass. A 12V trigger is provided along with automatic music sensing for remote on/off functions. The amplifier has dual RCA unbalanced inputs and a single Euroblock balanced input. It features a selectable limiter with a three-position subsonic filter.

Suitable for distribution of mono audio to speakers throughout a facility, the amplifier can be used in applications that include hospitality, corporate, retail, education, government, themed entertainment and more. The unit is powered via an internal 110 to 240 VAC power supply. The amplifier is housed in a powder-coated steel chassis that can be rack mounted in a 2U rack space. All controls located on rear panel-deterring unauthorized tampering with levels or other settings.
