XR1-E

The XR1-E is an analog ring modulator with internal oscillator, preamp and LFO in a nice hand-made casing. It offers a wide variety of sounds, from the typical ring modulation and tremolo-like sounds to glissando and random-like patterns or distortion. An integrated low-noise preamp (with much headroom) allows to adapt any kind of input sources like microphones, e-guitars or electronic instruments. A bicolor LED provides optical control of the oscillator and preamp’s overdrive behaviour. The oscillator frequency is manually adjustable with two knobs for coarse and fine tuning and a has a switch for high and low (tremolo or bass) range. An envelope follower, a LFO and a Sample+Hold is provided for frequency modulation; further, there is a minijack 1V/oct. input for controlling the XR1-E’s frequency by an external CV. The envelope CV also can be optionally replaced by an external signal or a voltage from a foot pedal. 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 rear. 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.
