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. The digital output processing section includes Feedback Ferret, dual 5-band Parametric EQ or dual 28-band Graphic EQs, digital delay lines, and dynamics/limiters. The output section can be configured for Stereo, Dual Mono or Subwoofer mode with a built-in electronic crossover. The mixer features dual USB 2.0 ports, and the "A" USB connector allows streaming of digital audio directly to a computer or memory stick as well as exclusive, built-in MP3 compression. You can record your rehearsals, songwriting sessions or live performances directly to an inexpensive USB stick ... no other hardware needed and then transfer them to your computer to burn CDs or to transmit electronically. Or insert a memory stick to playback audio files for use between sets.
