The Peavey 24FX 24-Channel Mixer with effects combines exclusive Silencer mic preamps, dual DSP engines, dual USB ports, and built-in MP3 compression for exporting audio directly to a computer.The Peavey mixing console employs their state-of-the-art technology to enhance live sound reproduction and project studio recording, including Silencer mic preamps, which allow very high gain with low noise and distortion for crystal-clear signal reproduction. The audio mixer’s dual USB ports allow streaming of digital audio directly to a computer or memory stick and also feature exclusive, built-in MP3 compression. The mixing console’s 4 pre-fader auxes per channel—used with 4 master aux controls—facilitate use as a live sound monitor mixer, while the 2 post-fader auxes are ideal for adding effects (those built-in or outboard). Dual DSP engines enable you to use multiple effects simultaneously assignable to any channel via aux 5/6 or DSP engine 2. Onboard effects include reverb, delay, compression, de-esser, chorus, and gate/expander.
