Singular Audio filterdrve 500 Series Filter Module - Mono

The Singular Audio filterdrve is an adaptation of the famous Korg MS-20 analog filter for the 500 series format. This is the mono version. The filterdrve has everything you want in a 500 series filter, such as balanced I/O, low noise, great headroom, etc. The flilterdrve also includes overdrive, audio feedback into the cutoff control and a controllable gain structure.

The real killer is that this filter, coupled with the drive and resonance, really screams. Hence, the name: filterdrve.

Low noise NE5532 opamps are used for great noise performance, while retaining the squelching sounds of the original. Self-oscillation can be attained with the peak control at maximum. The filter can be switched from low to high-pass operation. The bypass switching is done with hardware relays, for full bypass transparency.

The filterdrve runs on a 16V bipolar power supply, which allows for a lot of headroom. The drive control reduces the headroom, for overdriven sounds. Noise is much lower than the original MS-20 filter.

The filterdrve has alpha metal pots (knobs), an anodized black aluminum faceplate which is laser engraved, and good quality switches.
