LPS SERIES
The LPS Series of power amplifiers from Crown® represents a new era in afford- able, 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,
Features include XLR inputs, Speakon® and binding post outputs, stereo/parallel/bridge- mono mode, power/fault/signal presence/clip indicators,
With over six decades of experience designing and building
