Electro-Harmonix Mainframe Bit Crusher Effects Pedal
Electro-Harmonix Mainframe Bit Crusher Effects Pedal
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.
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!
Specifications:
- 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
