Weiss EQ1-Linear Phase Equalizer Download + Review

What is the use of Weiss EQ1-Linear Phase?

The Weiss Linear Phase Equalizer EQ1 is packed with four different configurations. All of them work at 24/96. The basic model is the EQ1MK2, 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

Some Key Features common to all four models:

• Seven similar types of parametric bands. All seven bands control the entire audio frequency range. Each band has Q/Slope knobs Boost/Cut, and Frequency. Each band operates in any of the following modes: High shelving, low shelving, peaking, high cut, low cut, bypass.
• 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.
• It will provide you A/B compare memory, 128 snapshot bank + 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.
• 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.
• Bypass, overall gain, CH1/2 independent or ganged.

How to configure EQ1?

EQ1-MK2
The EQ1-MK2 is the base model and offers all of the above features.

EQ1-LP, the EQ1-MK2 with linear phase response
The EQ1-LP has the same parameter set as the EQ1-MK2 and is therefore fully snapshot and MIDI control compatible. Sampling frequencies supported are 44.1, 48, 88.2 and 96kHz.

The outstanding list of features of the EQ1-MK2 is in the EQ1-LP further we add a linear phase response. This means that the delay introduced by processing is now constant across the whole spectrum, unconstrained by eq settings – this is not the case with standard equalizers, where signal delay varies with frequency, with the length of the delay depending on the amplitude response.

The sound, or character, of an equalizer has been said to be influenced by phase response (for example John Watkinson: ..much of the audible difference between EQs comes down to the phase response., Studio Sound 9.97). The EQ1-LP is therefore the ideal tool for corrective amplitude adjustment, without the unwanted phase distortion added by standard equalizers.

The linear phase feature can be turned off, resulting in the exact same sound as the EQ1-MK2. So for creative sound designing, there is the benefit of two different equalizers in one machine.

EQ1-DYN, the EQ1-MK2 with four dynamic bands
Very first time, Weiss Engineering design an exciting new feature to its EQ palette: dynamic control in the frequency domain.
WHen you need to adjust the EQ to a nominal setting. The input signal is then analyzed to determine exactly how much equalization require to be applied. If the signal is already loud in a certain band, Weiss 1 EQ will not boost it even more. Or, alternatively, if you want to attain certain frequencies, these are only attenuated when they will be up from 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.

EQ1-DYN-LP, Dynamic and Linear Phase EQ in a single unit
The EQ1-DYN-LP contains both the Dynamic and the Linear Phase EQ programs. After power-up of the unit, the user can chose between Dynamic (DYN) and Linear Phase (LP) modes. This allows to use a single unit for a wealth of different equalizing tasks.

The workspace storage, the snapshots and the snapshot backups are fully independent between the DYN and LP parts of the unit. This means that all setup data are retained in any case. Users of EQ1-LP and EQ1-DYN units can upload their current snapshot data into the EQ1-DYN-LP via MIDI.
