iQ505
Sontec MEP-250A Style, 5-Band Fully Parametric
Sontec-Inspired Precision in a Compact Format
iQ505 is a fully parametric five-band equalizer modeled after the revered Sontec MEP-250A, condensed into a single 500-series module. Its overlapping bands provide seamless coverage across the entire audible spectrum and beyond, from deep sub-bass to extended high-frequency air.
Total Control with Fully Adjustable Bands
Each band offers up to ±12 dB of boost or cut and features a dedicated Q control, enabling engineers to move effortlessly between broad tonal shaping and extremely narrow, corrective adjustments.
Ultra-Transparent Analog Performance
Designed for clarity above coloration, iQ505 is one of the cleanest equalizers in the IGS lineup. Electronically balanced inputs and outputs using modern THAT chips ensure low noise, high headroom, and exceptional transparency.
Built for Surgical Work and Subtle Enhancement
iQ505 excels at notching problematic frequencies, carving space in dense mixes, and making precise mastering adjustments. While neutral in character, it remains musical and responsive, making it equally effective for fixing issues or delicately sculpting sound.
