The HTA125A from Bogen is a 125W power amplifier that uses MOSFET technology for superior performance and reliability. This versatile amp drives a variety of loads such as 25/70V and 4/8 ohms. The HTA125A has thermal protection to deliver full output even at temperatures up to 131°F. Additional protection is provided by electronic overload limiting, short circuit protection, and a Slo-Blo fuse. Electronic shutdown circuitry is automatically activated if an overload or short occurs and the front-panel overload shutdown LED illuminates. Once the cause has been rectified, the unit automatically resets.
