Altec Lansing 1590E User Manual

1590E
Power Amplifier
KEY FEATURES
* DC Voltage Backup Ensures
Uninterrupted Operation
* Switchable High-Pass Filter
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).
