DESCRIPTION
The Altec Lansing
1590E
Power Amplifier is
designed for applications where uninterrupted operation
is a priority. The
1590E
provides 200 watts of power at
less than 1% total harmonic distortion (THD) from 50 Hz
to 12 kHz, and has a frequency response of -1 dB from
20 Hz to 20 kHz at one watt output. Output transformer
taps provide connections for 70.7, 100, 140 and 200
volt line distribution systems.
The
1590E
features silicon solid-state circuitry, a
switchable high-pass filter for use in speech systems,
input connections for high impedance devices and for
150/600 ohm or 15,000 ohm balanced inputs, fail-safe
protection for output transistors, and a hinged front
panel for rapid access to the chassis interior.
The
1590E
is capable of operation from a negative
grounded 24/28 V DC source. The
1590E
is UL listed
for use in commercial audio systems and fire protective
signaling systems.
Designed for rack-mounted use, the
1590E
occupies
six units of vertical space. 10.5 inches (26.7 cm).
