The Soundtube MA501T is a low-voltage mono power amplifier engineered for use in distributed sound applications. Designed for use with SoundTube and other high-fidelity speakers, the Soundtube MA501t provides 50 watts of output power at 25V, 70V or 100V. A 12V trigger is provided for auto-on/off functions. Recessed gain control is available via the front panel; this deters unauthorized tampering with levels or other settings.
