XR1-E
Ring Modulation Oscillator
The XR1-E is an analog ring modulator desktop device with internal oscillator, preamp and LFO
in a nice hand-made casing.
It offers a wide variety of sounds, from the typical ringmodulation- 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 offers optical control of the oscillator's and preamp's overdrive behaviour.
The oscillator frequency is manually adjustable with two knobs for coarse and fine tuning and a switch for high and low
(tremolo) range. An envelope follower, a LFO and a Sample+Hold is provided for frequency modulation; further, there is a
minijack 1V/oct. input for control by e.g. an external synthesizer and another frequency control input for e.g. a pedal.
The XR1-E also offers a footswitch input socket to apply an external footswitch (not included) for switching between the
effect and the original. The XR1-E works with true bypass routing. Further, 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 also a socket
for external DC (6-15V).
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.
