Analog 3 Band Equalizer and Compressor Module
User Guide
Thank you for choosing CEQ for your Eurorack System.
Powering up
- Turn off the power of your modular synthesizer.
- Double check the power cord polarity. If you plug the module backwards you might damage its electronic circuits.
If you flip over your CEQ, you will find the “RED” mark at the PCB power connector, which must match the colored line on the ribbon cable. - Once you have checked all the connections, you can turn on your modular system.
- If you notice any anomalies, turn your system off right away and check again your connections.
Description
CEQ is an analog 3-band Equalizer and Compressor module in 4HP.
What is a 3 Band Equalizer?
CEQ has 3 equalization controls, which allow the user to adjust the tonal
balance of the input audio signal: high, mid, and low.
Each control adjusts the level of a specific frequency range in the audio
signal and can be used to boost or cut the level of the corresponding
frequency range, which allows the user to adjust the tonal balance of the
audio signal to their liking.

And a Compressor?
One-knob compressors are a type of audio processing tool that simplify the
process of applying dynamic range compression to an audio signal.
The basic principle behind a one-knob compressor is to automatically reduce
the level of the audio signal when it exceeds a certain threshold, and then
gradually increase the level as the signal decreases. This helps to even out
the dynamic range of the audio, making quieter sounds louder and louder sounds
quieter.
One-knob compressors can be especially useful for beginners or less
experienced audio engineers who may not be as familiar with the intricacies of
more complex compression.

Controls
• HIGH
The high EQ control is a high-pass filter that reduces the level of
frequencies above 2567 Hz. This control is used to adjust the treble or “top
end” of the audio signal.
• MID
The mid EQ control is a bandpass filter that allows the user to adjust the
level of a specific frequency range, from 256 Hz to 2567 Hz. This control is
used to adjust the midrange of the audio signal, which can be important for
making vocals or other instruments stand out in the mix.
• LOW
Fig.2 Detail of EQ Controls
The low EQ control is a low-pass filter that reduces the level of frequencies
below 256 Hz. This control is used to adjust the bass or “bottom end” of the
audio signal.
• COMP
Adjusts the ratio of the compression, which determines how much the audio
signal is reduced when it exceeds the threshold. Higher ratios result in more
aggressive compression, while lower ratios result in more subtle compression.
This One-knob compressor also includes automatic makeup gain, which
automatically adjusts the output level of the audio signal after compression
so that the overall level remains consistent.
Inputs & Outputs
• Stereo Inputs L · R
Stereo inputs allow you to process external stereo sources through the modular
synthesizer. Audio is normalled from L to R.

• Stereo Outputs L · R
Stereo outputs allow you to send separate signals to each side of a stereo
sound system.
