The Bogen HTA Professional Series Power

Amplifiers are high-performance units employing

state-of-the-art Power MOSFET technology. The

characteristics of Power MOSFETS make them

ideally suited to power amplifier design, providing

far superior performance and reliability compared

to other types of transistors. They afford higher

efficiency, reduced heat, simpler overall design,

reduced size and weight.

The Model HTA125A supplies 125 watts (RMS

continuous output) at less than 0.5% total har-

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

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

put. The input impedances are: high-impedance

(50,000

(500/600 ohms, balanced or unbalanced) with

optional accessory transformer Model TL600. Line

bridging can be achieved with an optional trans-

former Model TL100. 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 HTA125A can drive a variety of load imped-

unbalanced;

low-impedance

ances: outputs include 4 ohms, 8 ohms, 25 VCT and

70 volts. It is capable of safely driving any recom-

mended load continuously. The HTA125A is ther-

mally protected to prevent damage due to exces-

sively high temperatures; however, the amplifier

will deliver the full rated power output continu-

ously, even at +131ºF (+55ºC). Additional failure

protection devices include electronic overload lim-

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

Electronic shutdown circuitry is automatically acti-

vated if an overload or short circuit 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 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 low-cut filter switch is

located internally.

Specifications subject to change without notice.
