The Bogen HTA-250A Power Amplifier is a high-

performance unit employing state-of-the-art

Power MOSFET technology. The unique charac-

teristics of Power MOSFETS make them ideally

suited to power amplifier design, providing far

superior performance and reliability compared to

other types of transistors. They offer higher effi-

ciency, reduced heat, simpler overall design,

reduced size and weight.

The Model HTA-250A supplies 250 watts (rms

continuous output) at less than 0.5% total har-

monic distortion from 20 to 20,000Hz. An input

signal of only 500mV is required for full rated out-

put. The input impedances are: high-impedance

(50,000 ohms) unbalanced; low impedance

(500/600 ohms, balanced or unbalanced) with

optional accessory transformer Model TL-600.

Line bridging can be achieved with optional trans-

former Model TL-100. Residual hum and noise is at

least 90dB below rated output and the output reg-

ulation is better than 2dB from no load to full

load.

The HTA-250A can drive a variety of load imped-

ances. Outputs include 4 ohms, 8 ohms, 25VCT

and 70.7 volts. The amplifier is capable of safely

driving any recommended load continuously. The

HTA-250A is thermally protected to prevent dam-

age due to excessively high temperatures; howev-

er, the amplifier will deliver the full rated output

continuously, even at +49°C (+120°F). Additional

failure-preventive devices include overload limit-

ing, short circuit protection, and a Slo-Blo fuse.

Electronic shutdown circuitry is automatically

activated if an overload or short occurs and a

front panel overload shutdown LED illuminates.

Once the cause has been rectified, the unit auto-

matically resets. The power on/off switch, located

on the front panel, illuminates when power is on.

The rear panel contains an input level control,

input and output connections, the ac line fuse, and

an auxiliary receptacle. A low-cut filter switch is

located internally.
