Radial Engineering Q4 500 Series 4 Band Equalizer Module

The Radial Q4 is a unique equalizer that combines the warmth and detail of a pure class-A circuit with the character of true 100% discrete state-variable filters. In other words, no integrated circuits are employed whatsoever. Each full size through-hole part is carefully inserted by hand and then wave soldered to ensure optimal signal flow. This produces a level of sonic warmth and musicality that excels above the others.

Features:

• Four band semi-parametric equalizer
• 100% discrete class-A state-variable filters
• Sounds exceptionally warm and natural
• Fits all standard 500 series power racks
