CEQ Quick guide
Thank you for choosing CEQ for your Eurorack System. Powering up 1. Turn off the power of your modular synthesizer. 2. Double check the power cord polarity. If you plug the module backwards you might damage its electronic circuits. RED RED 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. 3. Once you have checked all the connections, you can turn on your modular system. 4.
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.
Layout This image will clarify the function of each of the elements of the module. CEQ Stereo Inputs Audio is normaled from L to R. L R Stereo Outputs Modular voltage levels [±10V] L R HIGH Cutoff frequency: 2567Hz HIGH MID Cutoff frequency: 256Hz to 2567Hz EQ Controls MID LOW Cutoff frequency: 256Hz Max boost: +6dB, Max attenuation -∞dB Sallen Key filter configuration, Resonance factor Q = 0.
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. HIGH • 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.
Inputs & Outputs • Stereo Inputs L · R CEQ 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. L R L R Fig.
