Power Amplifiers
Features
Models HTA125A
• Power MOSFET circuitry
• Capable of continuous operation at rated output power
• Frequency response ±1dB, 20 - 20,000 Hz at full rated output
• Distortion less than 0.5% THD, 20 - 20,000 Hz
• Multiple output voltages/impedances available
• Automatic overload protection
• UL and C-UL listed
The Bogen HTA Power Amplifier Series are high-
performance units employing Power MOSFET tech-
nology. The unique characteristics of Power MOS-
FET circuitry make them ideally suited to power
amplifier design, providing far superior performance
and reliability compared to other types of transis-
tors. They offer higher efficiency, reduced heat, sim-
pler overall design, reduced size and weight.
The HTA125A Model supplies 125 watts and the
HTA250A Model supplies 250 watts (rms continu-
ous output) at less than 0.5% total harmonic distor-
tion from 20 to 20,000 Hz. An input signal of only
500mV is required for full rated output. The input
impedances are: high-impedance (50,000 ohms)
unbalanced; low impedance (500/600 ohms, bal-
anced or unbalanced) with optional accessory
transformer Model TL600. Line bridging can be
achieved with optional transformer Model TL100.
Residual hum and noise is at least 90 dB below
rated output and the output regulation is better than
2 dB from no load to full load.
and HTA250A
The amps can drive a variety of load impedances.
Outputs include 4 ohms, 8 ohms, 25VCT and 70
volts. The amplifiers are capable of safely driving any
recommended load continuously. The HTA Series
amps are thermally protected to prevent damage due
to excessively high temperatures. Additional failure-
preventive devices include overload limiting, short
circuit protection, and a Slo-Blo fuse.
Electronic shutdown circuitry is automatically acti-
vated 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 power ON/OFF switch, located on the
front panel, illuminates when power is on. The rear
panel contains an input level control, input and out-
put connections, the AC line fuse, and an auxiliary
receptacle. A low-cut filter switch is located internally.
Specifications subject to change without notice.
