Bogen HTA250A 250-Watt Rack-Mounting Power Amplifier
250-Watt Rack-Mounting Power Amplifier
The Bogen HTA250A Power Amplifier is a high performance
unit employing Power MOSFET
technology. The unique 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 offer higher efficiency, reduced
heat, simpler overall design, reduced size and
weight.
The Model HTA250A 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
(50,000 ohms) unbalanced; low impedance
(500/600 ohms, balanced 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.
The HTA250A can drive a variety of load impedances.
Outputs include 4 ohms, 8 ohms, 25VCT
and 70 volts.The amplifier is capable of safely driving
any recommended load continuously. The
HTA250A is thermally protected to prevent damage
due to excessively high temperatures; however,
the amplifier will deliver the full rated output
continuously, even at +49ÃÃÃÃðC (+120ÃÃÃÃðF). Additional
failure-preventive devices include overload limiting,
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 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 output connections, the AC line fuse,
and an auxiliary receptacle.A low-cut filter switch
is located internally
