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).
