Sanctum

The VTR Effects Sanctum is a stereo dual-engine reverb pedal capable of running two independent reverb algorithms simultaneously. Each engine provides access to 13 algorithms—Cathedral, Spring, Ephemeral, Plate, Cloud, Room, Infinity, Hall, Spiral, Expand, Mod, Divided and Bloom—with independent decay, wet tone filtering, octave settings and algorithm-specific X/Y parameters. The two engines can operate in parallel for separate layered reverbs or in series, where Reverb A feeds Reverb B. Presets store both engines and their routing, while independent bypass and spillover allow reverb tails to continue during bypass or preset changes. Sanctum processes true stereo audio at 48 kHz and provides stereo inputs and outputs, MIDI In and Out/Thru, and USB-C for firmware, preset management and editing. It operates from 9V DC center-negative power.
