FX Series mixers feature new, Peavey-exclusive 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 four pre-fader auxes per channel provide 4 monitor mixes while the two post-fader auxes are ideal for adding effects (those built-in or outboard). These mixers also include dual DSP engines that allow multiple simultaneous effects assignable to any channel via aux 5/6 on DSP engine 2. Onboard effects include reverb,reverb enhanced, delay, compression,expander, de-esser, chorus, flanger, tube emulator, vocal enhancer and gate. Up to 3 processors can be chained together on each of the two available Effects windows.
