What is it? A range of new additions to Behringer's PMP Series of compact powered mixers designed for small to medium-size performance venues, houses of worship and other applications requiring lightweight, all-in-one, wireless-ready PA solutions. Details All four new models offer ULM 2.4 GHz wireless-ready operation, Klark Teknik digital multi-FX processors and Behringer's patented FBQ feedback detection system. The built-in 500W Class-D power amplifier is also common to the PMP500, PMP580S, PMP550M and PMP560M models which provide input configurations of 12, 10, 6 and 5 channels (respectively) whilst offering half the depth and weight of most conventional designs. 'Invisible' IMP mic preamps include switchable +48 V phantom power for condenser microphones, with the Klark Teknik effects processors offering 25 presets including reverb, chorus, flanger, delay, pitch shifter and various multi-effects. The design also incorporates "studio-grade" compressors with one-knob functionality and control LEDs (on all models except the PMP550M), and the FBQ feedback detection system instantly reveals critical frequencies for easy feedback removal. And another thing... Built-in, dual 7-band graphic EQ allows precise frequency correction of monitor/main outputs (PMP500: stereo graphic EQ; PMP550: single graphic EQ).
