Need help?Do you have a question about the SPL Passeq and is the answer not in the manual?
Activation of the Analog Code plug-in requires an account on Plugin Alliance. Setup can be done anytime via their website.
Information regarding system requirements and supported platforms or formats can be found by visiting the provided web page.
Instructions for installing the plug-in on MAC and Windows systems, including checking for the latest version and executing the installer.
Describes the Passeq as the most powerful passive EQ system, highlighting its 12 switchable frequencies per band for boost and cut stages.
Details how the Passeq Analog Code plug-in faithfully reproduces the unique sound quality of the original hardware, emphasizing complex filter interactions.
Explains the selection of fixed frequencies for the Passeq, driven by audio experts' preferences and designed for musically sensible choices and S-curve EQ-ing.
Details the low cut frequency range (30 Hz - 1.9 kHz) and low boost band (10 Hz - 550 Hz), explaining their shelving characteristics and frequency choices.
Describes the midrange bands' peak filter characteristics, the MF-MHF cut overlap, and the LMF-MHF boost band frequencies and range.
Explains the MHF-HF cut band's shelving characteristic and the HF boost band's variable Q peak filter characteristic in the high frequency range.
Details the proportional or variable Q principle for HF boost, explaining how settings affect boost levels and bandwidth for desired sonic results.
Describes the MHF-HF cut band as a shelving filter for reducing higher frequencies with a wide bandwidth, extending to 19.5 kHz.
Explains the output control as an output level regulator, allowing reduction of level up to -66dB with fine resolution for smooth adjustments.
Advises setting levels properly before using EQ, suggesting that if more than 6dB boost is needed, initial levels should be thoroughly investigated.
Details M/S encoding as a useful stereo technique for signal processing, explaining how signals are separated and converted between L/R and M/S formats losslessly.
