5 Band Stereo EQ with 3 fully parametric Bands, Hi-Low-EQ and 24 dB boost/cut Range.
The W789 is a top class 5-band stereo equalizer with best tonal qualities and huge control ranges. These equalizers are used with the stereo channels of the large format, music production consoles of the 5MT series. The equalizers are designed based on adt-audio's vianna bridge principles and remain musical, even with extreme settings. Clear but soft highs and voluminous but transparent bass sounds mark out this outstanding stereo equalizer.
The three fully parametric bands cover the entire audio band from 20 Hz to 25 kHz. In combination with the huge bosst/cut ranges of +/- 24 dB the stereo EQ makes possible tonal treatment beyond your expectations.
A mastering version of the 5-band stereo EQ, the W789m, with adapted control ranges, is also available. Inputs and outputs of the module are balanced and can be implemented transformer balanced or electronically balanced. The maximum internal and external operation level is + 30 dBu. The stereo EQ is precisely adjusted to best possible tracking accuracy of both channels
Three of the five EQ bands are fully parametric bell filters with adjustable center frequency and q-factor. The sweep range of each band is 1 to 100. The MID1 band, which can also be considered as additional low band covers the range from 20 Hz to 2 kHz, MID2 ranges from 60 Hz to 7 kHz, and the MID3, which actually is a second high band, starts down at 250 Hz and reaches up to 25 kHz. Due to the overlapping ranges, extensive treatment of bass signals with small q-factor settings is possible as well as combining wide and small q-factor settings in the same frequency range. Using small q-factor settings in the bass range results in voluminous but clean bass sounds and clear separation of kick drum and bass. The range of the q-factor controls is identical for all bands and allows variation from 3 octaves down a third.
The adt-audio 'Vienna Bridge' equalizers operate similar to passive LC EQ's and are free from intermodulation and TIM. Even extrem settings remain clean and musical.
HI- and LOW-EQ are pre-adjusted to the most important characterics and allow to accomplish standard eqing very fast and easy.
The HI-EQ can be switched to 3 different characteristics. In the 20 kHz position it operates a as soft baxandall eq with a corner frequency far above 20 kHz. Boosting results in silky, clean highs. The 12 kHz and the 8 kHz switches over to a very soft bell with the particular center frequency. This setting results in high frequency 'pressure'.
The LOW-EQ has always soft bell characteritcs. A shelving EQ in the low range would cause boosting the subsonic range, which would make necessary to limit the boost by an additional high-pass filter. The characteristics of the low EQ avoids the need for the high-pass which results in a better phase response that maintains bass transparency. The center frequency of the soft bell can be switched to 100 Hz, 60 Hz or 40 Hz. Die Güte des LOW-EQ liegt bei ca. 1. Seine
The tonal characteristics of all bands are adapted to the frequency ranges of the particular bands. The high equalizer is optimized for soft operation and silky sounds, while the upper mid range is optimized for brilliance. Lower mid range and the low EQ are focussed on transparency and tightness. We can adapt all bands to your wishes, from 'hart' to 'soft'.
The hard bypass connects inputs and outputs and separates also the internal inputs from the connectors when the module is switched off.
A mono version of the W788 stereo equalizer, the W788, is also available. The device is a single slot V700 standard module that fits into standard V700 frames.
