Buzz. Beep and bloop. We’re high on the lo-fi sounds of “old-school”
games, toys and terminals and the Mainframe Bit Crusher takes us back in
time to when Pac Man and Donkey Kong ruled the arcades, to when the
Commodore 64 was high tech.



It provides sample rate reduction ranging from 48kHz to 110Hz. A little
background… the sample rate is the number of times per second that a
sample or snapshot of an analog signal is taken. For example, CDs
(remember them?) had a sample rate of 44.1kHz which means that the
original analog signal is sampled 44,100 times per second.



The sample rate defines the frequency range that can be reproduced while
maintaining good fidelity. When the sample rate is reduced the quality
of the audio is degraded and aliasing occurs. Aliasing means audible
artifacts created when higher frequencies are sampled at an inadequate
rate and the result is distortion. The Mainframe’s sample rate range is
wide enough to take you from sounds that are quite pristine to sounds
that are unrecognizable when compared to the input signal. 

It also provides bit crushing ranging from 24-bit to 1-bit. What does
that mean? Bit crushing is bit depth reduction. Back to our CD example…
CDs used a 16-bit bit depth meaning that each of its samples was
represented by 16-bits of information. Higher bit depths can accurately
represent a greater dynamic range while bit crushing increases the
number of sampling errors and creatively degrades the sound to bring us
back to those nasty “old school” sounds we love.



The Mainframe’s selectable High/Low/Band-Pass filter lets the user shape
the artifacts of the bit crushing and sample rate. Another very cool
feature is its Sample Rate Tuning Mode where the pedal analyzes your
input signal in real-time and sets the sample rate to match the pitch of
your signal, or a set interval above your signal. This allows you to
set the sample rate to match the key of a song, or it will continually
adjust the sample rate based on what you play!



QUICK SPECS:

• Sample Rate Reduction ranging from 48kHz to 110Hz

• Bit Depth Reduction ranging from 24-bit to 1-bit

• Selectable High/Low/Band-Pass filter to shape the artifacts of the bit crushing and sample rate reduction

• Sample Rate Tuning Mode allows you to set the sample rate to match the
key of a song, or continually adjust the sample rate based on what you
play on your instrument

• Programmable preset or expression pedal setting allows you to save
your sound or control any combination of the Mainframe’s knobs with an
external expression pedal

• Secondary knob parameters allow you to fine-tune the Mainframe’s effect.

• High quality buffered bypass and silent switching

• Comes equipped with an Electro-Harmonix 9.6DC-200mA PSU
