LPS SERIES
he LPS Series of power amplifiers from
Crown® represents a new era in afford-
Table, quality power amplification. All three
models in the series are powerful, rugged and
reliable. They are suited for applications such as
churches, concert tours, stages, disco, pubs, or
any place that requires amplifier installation.
The three models in the series are the LPS-
800, LPS-1500 and LPS-2500. They are identi-
cal except for output power.
Features include XLR inputs, Speakon® and
binding post outputs, stereo/parallel/bridge-
mono mode, power/fault/signal presence/clip
indicators, forced-air cooling; and protection
against shorts, no-load, on/off thumps and
radio-frequency interference. Every LPS Series
amplifier is backed by a one-year limited war-
ranty.
With over six decades of experience designing
and building rock-solid products, Crown is the
standard in amplifier technology. So check out
the affordable Crown LPS Series. They are a
powerful argument for quality and value!
Features
•
Stereo/parallel/bridge-mono mode
•
•
Two level controls, power switch, power
LED, and six LEDs which indicate signal
presence, clip and fault for each channel
•
Efficient forced-air cooling prevents exces-
sive thermal buildup
