Weiss EQ1-DYN - 7 Band Equalizer

EQ1-DYN, the EQ1-MK2 with four dynamic bands

The EQ1 is available in four different configurations. All of them work at 24/96. The basic model is the EQ1-MK2 which is offered here, 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.


The EQ1-DYN

For the first time, Weiss Engineering brings an exciting new feature to its EQ palette: dynamic control in the frequency domain.
You adjust the EQ to a nominal setting. The input signal is then analyzed to determine exactly how much equalization need actually be applied. If the signal is already loud in a certain band, it is not boosted even more. Or, alternatively, if you want to attenuate certain frequencies, these are only attenuated when they exceed a certain level.

Multi-band dynamic? Or dynamic multi-band?

The EQ1-DYN features four freely adjustable dynamic bands, and additionally three linear bands per channel. Setting up the dynamic bands is as easy as setting a linear band. There is just one additional parameter to be adjusted by the user, the threshold control. This makes multi-band dynamic control as easy and as versatile as adjusting a parametric equalizer.

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. 
• Peak meter, over indicators.
• MIDI control for each parameter.
• Bypass, overall gain, CH1/2 independent or ganged.
