The HTA125A can drive a variety of load impedances: outputs include 4 ohms 8 ohms 25 VCT and 70.7 volts. It is capable of safely driving any recommended load continuously. The HTA125A is thermally protected to prevent damage due to excessively high temperatures;however the amplifier will deliver the full rated power output continuously even at +55 C (+131 F).Additional failure-preventive devices include electronic overload limiting short circuit protection and a slo-blo fuse. Electronic shutdown circuitry is automatically activated if an overload or short circuit occurs and a front panel overload shutdown LED illuminates. Once the cause has been rectified the unit automatically resets. The power on/off switch located on the front panel illuminates when the power is on.The rear panel contains an input level control input and output connections the ac line fuse and an auxiliary receptacle.A lowcut filter switch is located internally. Features: 125 Watts Designed for continuous operation at rated power up to 120 deg. F; convection-cooled Thermal protection and automatic electronic overload protection 4-ohm 8-ohm 25V & 70V outputs.
