Radial Q4 500-Series Parametric Equalizer

The Radial Q4 500-Series Parametric Equalizer 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. Featuring 100% discrete, hand inserted parts and a bypass switch for instant A/B comparison, the Q4 sounds exceptionally warm and natural with almost no negative feedback for pure tone.

The Radial Q4 500-Series Parametric Equalizer employes no integrated circuits 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.

Designed to fit in the Radial Workhorse and other 500 series racks, the Radial Q4 features four frequency bands with high and low shelving at 10kHz and 100Hz and two semi-parametric mid sections that let you sweep frequencies from 300Hz to 8kHz. The two mid-bands can be further optimized by selecting either a wide or narrow Q. All frequencies may be cut or boosted by up to 12dB - affording plenty of range. A handy 'bypass' switch lets you compare the dry tone with the EQ's effect and for those equipped with a Workhorse, the Omniport is designated as an unbalanced ¼" TRS input/output connection that can be inserted into a console channel strip using a single TRS cable.

This makes the Radial Q4 a wonderful choice for adding analog character to a voice or instrument and a natural for enhancing music program material.
