Sontec MEP-250A Style, 5-Band Fully Parametric

iQ505 is a five-band fully parametric equalizer inspired by the legendary Sontec MEP-250A, redesigned for the 500-series format. Featuring overlapping bands with ±12 dB boost or cut and an exceptionally wide frequency range extending from sub-bass to 24 kHz air, it delivers precise and transparent tonal control. Each band includes independent Q adjustment, allowing both broad shaping and surgical correction. With electronically balanced inputs and outputs powered by modern THAT circuitry, iQ505 offers ultra-clean performance, making it an ideal tool for corrective EQ, detailed sculpting, and high-precision studio work.

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.

We needed hardware that looks good in client-facing environments and performs consistently. Their products tick both boxes. The minimalist design is beautiful on camera, and the durability has been excellent.

The dynamics processor is ridiculously good. Smooth compression, no weird pumping, and the controls respond exactly as expected. It’s become my go-to for vocals and acoustic guitars.

We installed their signal distribution system across two rooms, and it’s been flawless. Zero hum, zero dropouts. The build quality is impressive — you can tell it’s made to last. Easily one of our best purchases this year.

Our studio upgraded to their 19″ rackmount units and the improvement was immediate. The layout is intuitive, connections are rock solid, and the unit hasn’t glitched once. Setup took minutes and everything just works.

Read moreI’ve been mixing on these studio monitors for the past three months, and the clarity is honestly next level. The stereo imaging is tight, the low end is controlled, and the build feels solid. It’s the first time I’ve used monitors in this price range that actually translate well outside the studio.
