KA SERIES 19″ RACK MIXER-AMPLIFIER

Product Description

KA200 – 100 + 100 WATTS
KA500 – 250 + 250 WATTS

These compact, stereo 1U amplifiers have been designed for small bars that require up to three mics and three stereo line inputs with voice override options.  The main objective is to cover all audio-visual and karaoke requirements in a venue where space is an issue.  When connected to a DVD/CD/CDG/MP3 player the potential of this amplifier is impressive.  Background music can be played in standard CD or MP3 format.  Karaoke files, and DVD/Satellite  can be displayed on a plasma screen.  All this plus an inbuilt digital effects processor with an output power of 100 watts or 250 watts per channel, in only 1U of rack space.
