Auxiliary Receptacle (not switched):
The power amplifier shall be a Bogen HTA Series Model
or approved equivalent using power MOSFET circuitry.
The amplifier shall deliver an audio output of 125 watts
(HTA125A) or 250 watts (HTA250A) (rms continuous).
Total harmonic distortion shall be less than 0.5% at the
125-watt or 250-watt rating over the frequency range of
20 to 20,000 Hz. The rated output shall be obtained with
an input that is not greater than 500mV (rms). Hum and
noise shall be at least 90 dB below rated output. The fre-
quency response, when measured at full rated output,
shall be flat within ±1dB, 20 to 20,000 Hz.
The amplifiers shall provide either balanced or unbal-
anced constant-voltage outputs of 25V, 25 VCT, and 70
volts, plus 4- and 8-ohm balanced or unbalanced
outputs. Output regulation shall be within 2 dB from no
load to full load.
The amplifiers shall provide an input of 50,000 ohms
unbalanced high impedance, or 600 ohms balanced or
unbalanced low impedance, or line bridging with optional
accessory plug-in transformers. Overall gain shall be
adjustable by means of a single level control located on
the rear panel. An internal low-cut filter (-10dB @ 100Hz)
shall also be provided. The front of the amplifiers shall
contain an illuminated ON/OFF power switch. The ampli-

fiers shall incorporate electronic shutdown circuitry which
shall activate whenever an overload or short occurs on
the output of the amplifiers. A front panel overload shut-
down LED shall illuminate to indicate the discontinuance
of power output; the circuitry shall automatically restore
power output once the cause of the shutdown condition
has been removed.
The amplifiers shall operate from a 120 VAC, 60 Hz
source. The HTA125A shall consume 45 watts or less at
idle and 260 watts at full rated power. The HTA250A shall
consume 60 watts or less at idle and 520 watts at full
rated output. The amplifiers shall have thermostatic
control to prevent operation at excessive ambient
temperatures. The amplifier also shall include electronic
overload limiting, short-circuit protection and a 4-amp
Slo-Blo fuse on the HTA125A or a 7-amp Slo-Blo fuse on
the HTA250A.
The amplifiers shall have a standard EIA 19-inch front
panel suitable for rack mounting. The amplifiers shall be
19" wide, 5-1/4" high and 11" deep, finished in black and
shall weigh 36lb. (HTA125A) or 50 lb. (HTA250A).
