Helix Board 12 Unversal is part of the new generation of Phonic's popular Helix Board mixers. It features 96 KHz USB 2.0 and FireWire interfaces that let you stream up to 10 independent channels of audio to the computer and return two channels to the mixer for monitoring - all with near-zero latency. Users are also able to utilize the main mix, ALT 3/4 and AUX 1 & AUX 2 signal for recording on the final two channels.Four extremely low noise Mic/Line preamps, each with 75 Hz low cut filters, inserts and phantom power, and two stereo Line channels offer a variety of input options. Pre/Post switches on each input channel allow users to adjust the outgoing USB 2.0 / FireWire signal between a pre-EQ, pre-fader, pre-low cut, to a post-EQ, post-fader signal. Each channel has a 3-band EQ and a mute button that sends the signal to the ALT 3-4 stereo bus, where several inputs can be grouped and controlled in tandem. Tracking individual inputs is easy with the stereo AUX cue. An onboard 32/40-bit digital multi-effect processor provides 100 popular programs, tap delay and test tones, and can be controlled through the use of a footswitch. Stereo RCA inputs and outputs make the addition of digital and analog playback and recording devices effortless. Additional features include two AUX sends, two stereo AUX returns, balanced stereo main outs, master AUX section with EFX to monitor, control room/phones source matrix and Steinberg's Cubase LE 5 digital audio workstation software.
