The 500-Watt 10-channel powered mixer with KLARK TEKNIK multi-FX processor, compressors, FBQ feedback detection system and wireless option. The amazing PMP580S powered mixer packs tremendous power (2 x 250 Watts stereo), while maintaining an incredible power-to- weight ratio. These mixers employ high-efficiency Class-D technology and a state-of-the-art switch-mode power supply, which significantly reduces weight and heat. The 10-channel PMP580S features 8 high-quality “Invisible” IMP mic preamps (2 of which also accept our ULM Digital Wireless Microphones, available separately), our “one-knob” compressors, 2 stereo channels and a 1⁄8" Aux Input for playing music from your smart devices. For that extra professional touch, we added a KLARK TEKNIK 24-bit Multi-FX processor with 25 presets including studio-class reverbs, delays, pitch shifter and various multi-effects, plus a 7-band stereo graphic EQ with our proprietary FBQ Feedback Detection System – for the ultimate in feedback-free performance.
