SoundTube Low Voltage Amplifier in Black

The 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 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.

The unit occupies two rack units; it is fan-cooled and offers overload, short circuit and heat protection along with peak output protection. All controls for the MA501t are presented on the rear panel. The MA501t is for use with SoundTube and Rockustics products. When in use in conjunction with outdoor speakers, the amp should be placed inside or in a weatherproof concealment.
