The XR1-E is an analog ring modulator with internal oscillator, preamp and LFO in a nice handmade casing. With a wide variety of control possibilties, the range of sound options reaches from the typical ring modulation and tremolo-like waveforms to glissando and random-like patterns or distortion.
An integrated low-noise preamp (with much headroom) allows to adapt any kind of input sources such as microphones, e-guitars or electronic instruments. A bicolor LED provides optical control of the oscillator and preamp's overdrive behaviour.
The frequency is manually adjustable by knobs for coarse and fine tuning and a switch for high or low (tremolo) range.  An envelope follower, a LFO and a Sample+Hold may be used for frequency modulation. The envelope CV can be optionally replaced by an external signal or a voltage from a foot pedal, appliable on a jack on the rear. Further, a minijack 1V/oct. input is available for controlling the XR1-E’s frequency by an external CV.
The XR1-E has a footswitch input to apply an external footswitch (not included) for switching between the effect and the original (true bypass). The output level of the processed signal can be aligned by a knob on the back.
Due to the ability of battery operation the device is independent from external power supply, but there is a socket for a DC adaptor too (DC adaptor not included).
The XR1-E is based on a function generator chip, which warm and smooth sound makes it excellently suitable for ring modulation and electronic music.Please note: Due to the handmade manufacturing process, there may be some little scratches/irregularities in the casing’s surface.
