The EQ1 is available in four different configurations. All of them work at 24/96. The basic model is the EQ1-MK2, the linear phase model is the EQ1-LP, the dynamic model the EQ1-DYN. The EQ1-DYN-LP incorporates both LP and DYN versions in one unit. The mode of operation (LP or DYN) can be chosen after power-up. All models are user-upgradeable to any other version.
Here are the main features common to all four models:
- Seven identical parametric bands. All seven bands cover the entire audio frequency range. Each band has Boost/Cut, Frequency and Q/Slope knobs. Each band operates in any of the following modes: High shelving, low shelving, peaking, high cut, low cut, bypass.
- One parameter per knob operation. Seven sets of controls for seven operating bands. Knobs are touch sensitive. LCD display shows detailed parameters of the touched band.
- Large, backlit Liquid Crystal Display which shows the overall frequency response (calculated in real time) and the detailed parameter values in dB, Hz and Q.
- A/B compare memory, 128 snapshot bank with two additional banks for back-up.
- Digital input / output in AES/EBU format on XLR connectors.
- Dithering to 16, 20 or 24 bits. POW-R dithering in the LP, DYN and DYN-LP models.
- 128 steps for boost/cut, frequency and Q parameters.
- Variable slope shelving filters.
- Very high Q (up to 650) for notching out offending frequencies.
- M/S mode for independent equalization of M and S channels. M/S encoder / decoder can be configured separately. Also see the article Stereo Shuffling: New Approach – Old Technique by Michael Gerzon
- Peak meter, over indicators.
- MIDI control for each parameter.
- Bypass, overall gain, CH1/2 independent or ganged.
