SPL Passeq 2-Channel Preamp EQ

channel) the PassEQ outperforms any previous machine of its type. Each channel is divided into three cut and three boost bands, each of which offers 12 switchable frequencies. Cut and bosst frequencies are not identical.Compared to existing passive EQ concepts, the PassEQ represents several different EQs in one unit with its large number of bands and frequencies. A further special PassEQ feature is the unique individual sonic design of each inductive filter through a dedicated coil/condenser/resistor combination, and each inductor is separately adapted for its respective frequency. Next to the peak filters (Mid boost & cut, HF boost) the PassEQ also provides hi cut, low cut, and low boost as shelving-filters. The HF band offers variable Q adjustments For the output gain amplifiers (necessary as make up gain for inevitable passive filtering signal reductions), PassEQ offers SPL’s SUPRA-OPs, which operate on unique 120 Volt rails. The SUPRA-OPs show an extraordinary S/N ratio of 116 dB, +34 dB of headroom, in turn giving dynamic range of ca. 150 dB - figures which clearly distinguish the PassEQ's processing in either analog or digital work, placing it in a leading position far in front of any digital or analog competition.
