Passive Mastering Equalizer
The new dual-channel PASSEQ (Model 1650/1654) is the resolute evolution of the highly acclaimed predecessor Model 2595.
The new PASSEQ now features Air band, a stepped output control ranging from -10dB to +10dB and a mid cut band now starting at 200Hz. These features were on the wish list of many mastering engineers.
Furthermore we have exchanged capacitor arrays in the filters by custom-made single capacitors and optimized the bandwidth per frequency range. This evolution is a sonic revolution.
The first generation Passeq was the first passive equalizer that offered high, mid and low band with individual boost and cut and with 12 selectable frequencies per band. Passeq was the most powerful passive EQ system ever made with a total of 36 boost and 36 cut frequencies. The sheer amount of possible frequency curves or shapes is close to 3 million.
Now, here is the 2nd generation: the new PASSEQ Mastering Equalizer. It features the same amount of boost and cut frequencies, though the choice of frequencies is altered and the Q-factor is more musically adjusted for each selectable frequency.
