The new FX2 features twice the processing power of the original. FX2 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 four monitor mixes, while the two post-fader auxes are ideal for adding effects (built-in or outboard). These mixers also include dual DSP engines that allow multiple simultaneous effects assignable to any channel via aux 5/6. Onboard effects include reverb, reverb enhanced, delay, compression, expander, de-esser, chorus, flanger, tube emulator, vocal enhancer and gate. Chain two processors together on each of the two available effects windows.
