Using the Bitrman

What is Bit Reduction?

The BIT REDUCER is an extreme combination of limiting and

distortion that’s not for wimps. By intentionally reducing the

digital resolution (or word length) of the signal, distortion and

noise increase, and dynamic range decreases. At high settings of

the [BITRNESS] knob, as the input signal fades, the noise in the

signal will become more apparent, so watch out! This is the

ultimate low-rez effect.

The [BITRNESS] knob is quantized in Bit Reduction mode to

provide 24-bit (bypass), 10-, 8-, 6-, 4-, 2-, and 1-bit resolutions,

with according jumps in after-stage gain to compensate.

What is Frequency Modulation (FM)?

At low speeds, FM (Frequency Modulation) mode simply adds

vibrato (up and down pitch change) to any signal. The vibrato

speed is controlled by the [BITRNESS] knob, and the vibrato

depth is fixed.

When the speed of FM is increased, so that the “vibrato”

frequency is as high or higher than the input signal, the effect

becomes more extreme. At high settings of the [BITRNESS]

control, the output can sound like signals from a touch-tone

phone (because FM is how those tones are created) or outputs

from a video game.
