Weiss EQ1 - DYN / LP

Weiss EQ1 MK2 LP/DYN 96 kHz Stereo 7- band Digital Mastering EQ

Trade-in possible!
I would also accept the following devices for trade-in (feel free - make a realistic offer):

- Sequentix Cirklon V2 Sequencer CVIO
- Alembic F1-X tube preamp
- Roland VP-330 MKII (in perfect technical serviced condition, only)
- Korg MS 20 Original Vintage  (in perfect technical serviced condition, only)
- Black Corp. Xerxes MK2

This unit was running after revision / checkup by Weiss CH max. 2hrs. This was one of my spare outboards. Still one of the best Mastering EQ's. I own another set i will never sell but i don't need spare units anymore. This unit is in a perfect technical and very good optical condition but i cannot find the manuals. If you like i can add a German power cord. It is a 220V version! No original box. I will send "bullet proofed" packed via DHL or. UPS insured only.

I hope i can find a great new home for this important part of Mastering, called the reference mastering EQualizer.

(The following text came from Weiss website)

The EQ1 is a two channel digital equalizer with seven parametric bands. It has digital inputs/outputs exclusively. The EQ1 is available in four different configurations. All of them work at up to 24 Bit/96 kHz. 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.

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 ft he unit, the user can chose between Dynamic (DYN) and Linear Phase (LP) modes. The workspace storage, the snapshots and the snapshot backups are fully independent between the DYN and LP parts ft he unit. This means that all setup data are retained in any case.

 LP Mode:

LP has the same parameter set and features as the EQ1-MK2. In addition it can be switched between minimum and linear phase behavior. Linear phase means that the delay introduced by processing is constant across the whole spectrum, unconstrained by the EQ settings. The sound, or character, of an equalizer has been said to be influenced by phase response as for example John Watkinson mentioned in Studio Sound magazine 9/97: “… much of the audible difference between EQs comes down to the phase response.” The EQ1-LP is therefore the ideal tool for corrective amplitude adjustment, without the unwanted phase distortion added by standard equalizers.

DYN Mode:

 Weiss EQ1 – the reference when it comes to digital mastering EQs. Available in four different models, including linear phase and dynamic versions.

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. The dynamic EQ can be used as a de-esser or to give the bass an extra punch etc..

Bands 1, 2, 5 and 6 are the dynamic bands (each individually switchable to linear) and bands 3, 4 and 7 are ordinary linear bands. A dynamic band operates similar to a compressor, with two additional features:

1) The band is sensitive to signal level in its frequency range only. So when applying dynamic bass EQ, only the bass-band of the program affects the dynamic behavior. There is no cross-modulation from other bands.

2) The gain is only applied to certain frequencies, and not across the whole audio band.

3) Other modes (low-cut, high-cut, low-shelving, high-shelving) are linear (no automatic boost/cut adjustment), and behave exactly the same as in the EQ1-MK2.

The reason for choosing exactly bands 1, 2, 5 and 6 is the following: As the name implies, a dynamic band is sensitive to the level of the input signal. Sometimes it is desirable to first add some EQ, and afterwards dynamically add some more. Or vice versa, first do some dynamic corrections and afterwards add overall EQ, including in the corrected band. Because the EQ bands are connected in series, this is only possible if there are linear bands before and after the dynamic bands.
