2-channel analog equalizer
The SPL PASSEQ is a 2-channel analog equalizer. The new dual-channel SPL PASSEQ (Model 1650/1654) is the resolute evolution of its predecessor, Model 2595. The SPL PASS EQ now features an Air band, a stepped output control ranging from -10dB to +10dB, and a mid-cut band that starts at 200Hz. These features were on the wish list of many mastering engineers. Additionally, we swapped capacitor arrays in the filters with individual custom capacitors and optimized the bandwidth for each frequency range. This evolution is a sonic revolution. The SPL PASSEQ offers adjustments for high, mid, and low frequencies with individual boosts and cuts, and with 12 selectable frequencies per band. The SPL PASSEQ was the most powerful passive EQ system ever made, with a total of 36 boost and 36 cut frequencies. An important part of the SPL PASSEQ's sound is produced by the loading and saturation characteristics of the coil and capacitor. The resulting inertia, in contrast to the fast reaction of active filters, is the reason for the pleasant sound we get from passive designs. Finally, each boost and cut frequency now has an optimized Q factor. Especially the mid bands (extended down to 200Hz) are more harmonious.
