BRITISH HANDBUILT STUDIO EFFECTS The RoXdon VR-202 Spring Reverberation Unit is a dual input classic analogue spring reverberation unit designed for use with a studio sound mixer or line level source. The circuit used in the VR-202 is similar to a classic vintage 1970's design with characteristics heard on countless recordings over the years, only achievable with a mechanical / analogue design. The RoXdon VR-202 is completely hand assembled in small batches, in London, England. The VR-202 signal path uses only discrete components like transistors, resistors and capacitors, with no integrated circuits. The subjective sound quality delivered by these classic vintage designs is often preferred over the sound of modern digital units and software created reverb delays. Particularly useful on vocals, the smooth, dark sounding, natural effect needs little manipulation other than adjustment of the intensity to create a lush mix ready vocal performance. The heart of the VR-202 is the mono 3-spring vintage replica reverb tank. The spring transducers are wired direct to the audio circuit board using screened cable. This makes the 'tank' less receptive to interference. Also close attention has been paid to the spacing and size of the transducer laminations resulting in a more vintage like tone. The double sided audio printed circuit board is hand soldered and features WIMA capacitors, carbon resistors and low noise transistors. All connections to the internal Audio Board are via soldered terminal posts, the way it used to be. The supplied external International 24volt DC regulated power adapter provides clean power to the VR-202 ensuring transformer magnetic fields are not present inside the chassis which can induce noise onto the sensitive spring tank. The power is 'cleaned' further by the inclusion of a ripple filter on the audio circuit board. The RoXdon VR-202 features a steel 2U 19" rack mounted enclosure manufactured with vintage black hammered finish front panel, retro style reverb intensity knob, dial, on/off switch and power-on lamp. The front panel also includes a convenient illuminated VU meter which provides a visual guide to the input signal level. The rear panel has a 24 volt DC socket for connection of the external power adapter (supplied) and 1/4" line input and output jack sockets for connection to a sound mixer or line level source. OPERATION When using the RoXdon VR-202 as a stereo reverb unit a left and right summed mono line level signal is fed to the side-chain drive amp circuit which drives the reverb spring. The delayed reverberation signals are then mixed with the left and right clean input signals equally. This circuit design emulates a 'real life' reverberation where the reflected sound waves come from all directions. When a mono reverb delayed signal only is required, eg. using mixer channel AUX, this can be accessed by using INPUT L together with OUTPUT R.
