Bogen HTA125A
Bogen HTA125A Mono-Channel Power Amplifiers
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.
The Bogen HTA Power Amplifier Series are highperformance units employing Power MOSFET technology. The unique characteristics of Power MOSFET circuitry make them ideally suited to power amplifier design, providing far superior performance and reliability compared to other types of transistors. They offer higher efficiency, reduced heat, simpler overall design, reduced size and weight.
The HTA125A Model supplies 125 watts and the HTA250A Model supplies 250 watts (RMS continuous output) at less than 0.5% total harmonic distortion from 20 to 20,000 Hz. An input signal of only 500mV is required for full rated output. The input
impedances are: high-impedance (50k ohms) unbalanced; low impedance (500/600 ohms, balanced or unbalanced) with optional accessory transformer Model TL600.
