Allen & Heath’s Xone VF-1 universal analog stereo filter made its U.S. debut at San Francisco-based dance music venue 1015 Folsom for an October show that featured well-known German DJ/producer Paul van Dyk, who was wrapping up the Rock the Vote Tour 2004.
Scot Peterson, 1015's sound designer and engineer, said, "There are two features I really appreciate about [the Xone VF-1]. First, the valve added a level of warmth and richness to our P.A. system that was astounding. Secondly, the balanced inputs and outputs and the lack of gain controls really make this unit somewhat foolproof. Virtually every other DJ effects unit on the market is a disaster in the hands of all but the most responsible and educated DJs. This unit isn't!”
The VF-1's circuitry is an enhanced version of the filters built into Allen & Heath's Xone mixers, and offers three basic 24dB/octave valve filter types: highpass, bandpass and lowpass. The basic filter types can be combined to create further filter types such as notch. The VF-1 also offers MIDI capability and incorporates an envelope follower and an LFO with triangle and square wave outputs.
