Description
The MA501t is a low-voltage mono power amplier
engineered for use in distributed sound applications.
Designed for use with SoundTube and other high-
delity speakers, the MA501t provides 50 watts of
output power at 25V, 70V or 100 V. A 12 V 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.
