Introduction

SPL Passeq—the most powerful passive Equalizer ever made

Unique Features

•The most powerful passive EQ ever made—72 (!) passive filters per channel in one EQ.

•120 V makeup amplifiers based upon SPL SUPRA-OPs with 150 dB dynamic rage and 200 V/ms slew rate.

•Individual coils per filter.

•Single core coils, which means that every one is wound individually on its own dedicated core. This excludes sonic degradation from mutual influences while at the same time improving THD values.

Special Features

•Individual design and component specificity for each filter.

•Custom made coils for critical mid-frequency ranges.

•Boost and cut crossovers mesh perfectly so that with the high number of frequencies one can dependably command the most elaborate set of response curves that to date any passive EQ has offered.

•Transformers from Lundahl with perfectly matched sonic characteristics provide for balanced I/O stages.
