SPL PQ Mastering Equaliser
Available in Red, Black or All Black finish.
PQ from SPL is acclaimed as one of the most powerful EQs available in modern studio mastering. Fully parametric, loaded with 10 bands across 5 channels, the PQ is a true testament to SPL’s attention to technical detail and commitment to world-class technology.
Built For The Mastering House
Each PQ unit is housed inside a 4U 19” rack-mountable chassis and armed with high-quality detented potentiometers, buttons and switches. Each control glides with solid precision and 41-way stepped pots allow for ease of exact recall between sessions – an indispensable feature for professional mastering tools.
Wield Complete Control
Every frequency band can be independently switched in and out with the option to switch between Constant and Proportional Q on the fly, while left-channel bypass functionality constant Q can be controlled by the right side whilst PQ is in Link mode.
PQ’s ‘1/4 Gain’ switch reduces the boost or attenuation amplitude by a factor of 3/4, changing the pot gain from a ±20dB max limit to ±5dB. With this tool, surgically minute corrections may be made to filtering to achieve the ultimate master.
Proprietary 120V Technology
Synonymous among SPL’s highest end professional audio tools, 120V ‘anti-overdrive’ technology is built in to every rail of the PQ’s circuitry allowing a healthy amount of headroom and a superior optimised dynamic range for rendering high quality audio material.
Worry-Free Automatic Bypass
Manual comparative toggling is an undisputed foe for any mastering engineer. To eliminate this, the PQ features a built-in Auto Bypass feature which switches between wet and dry signals at user-adjustable intervals, so engineers can remain in the sweet spot and get their job done.
PQ is a bullet-proof filtering tool for any mastering studio, and allows music to breath naturally completely natural while simultaneously avoiding listening fatigue
