Behringer BM-17 Frequency Box Analog Effects Generator
The Behringer BM-17 Frequency Box turns a pedal-format unit into a hands-on analog sound laboratory. Its voltage-controlled oscillator, envelope and frequency modulation controls shape. Everything from fuzz distortion to modular synth-style textures. Meanwhile, the mix control lets you balance the input signal with the oscillator output.
Shape Moving Analog Textures
Firstly, at the centre is a voltage-controlled oscillator, with Frequency and Waveform knobs for direct sound shaping. Envelope (ENV) Amount and FM Amount controls add expressive movement to the frequency modulation. Also, the Range switch selects the oscillator frequency range for a broader palette of tones.
Blend Input and Oscillator Sound
Moreover, drive sets the input gain, and the Mix control balances the incoming audio against the oscillator output. That makes it possible to reinforce an existing sound, move towards a more effected texture, or explore fuzz distortion and synth-style creation without losing the hands-on feel of a dedicated effects unit.
Connect It to Creative Setups
Expression pedal control is available for real-time adjustment, while the 6.3 mm audio and CV connections expose Audio In, Freq, Wave, Env Amt, FM Amt, Audio Out, Env Out, Osc Out and Mix. Use it with other BM series pedals or modular synth setups for expanded sound exploration.
Built for Hands-On Use
A compact, rugged design makes the unit practical to transport and use onstage. The effect bypass footswitch offers straightforward control, while the VCO Sync switch adds another way to work with the oscillator. Guitarists, synth players, producers and other instrumentalists can approach it as an effect, synth voice or standalone sound source.
