SPL Passeq Equalizer

The Passeq uses a passive filter design with coils and capacitors, which creates a more natural, inertia-driven response compared to the clinical precision of active filters. This approach mimics the sonic character of vintage 1950s and 60s gear, offering a warmer, more musical sound that feels less processed.

Yes, it is specifically designed for mastering. The inclusion of stepped potentiometers and switches allows for precise, repeatable recall, while the expanded high-frequency range provides the clarity and openness required for final mix adjustments.

The high-voltage circuitry significantly increases the unit's headroom, which helps maintain transparency even when you are pushing the signal hard. This ensures the equalizer handles high-level signals without introducing unwanted distortion or clipping.

Yes, the unit features an integrated auto-bypass function. This allows you to perform quick A/B comparisons between the equalized and dry signals, helping you make informed decisions about your adjustments in real-time.

The unit operates within a frequency range of 10 Hz to 35 kHz, with a transmission bandwidth extending up to 200 kHz. This wide range ensures that you have full control over the entire audible spectrum and beyond, preserving the integrity of your audio.

Yes, the SPL Passeq is a two-channel device, making it ideal for stereo bus processing or mastering tasks where you need to apply identical or balanced EQ settings to both the left and right channels.
