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.
