The IGS 576 Blue Stripe 500-Series Compressor is a new, compact recreation of the famed Blue Stripe 1176, adapted for the 500-series format! The 576 is a true peak limiter with all transistor circuitry and superior performance on all types of material.

The IGS 576 Blue Stripe 500-Series Compressor is a revised version of the classic FET compressor. The FET-type solution was first used for its application in the legendary UREI 1176 compressor from the 70s. The most important feature inspired by revision A is the input transformer used and pure class A output stage. The IGS 576 Blue Stripe 500-Series Compressor is equipped with a relay bypass, 2:1 Ratio and Slam Mode accessible on the front panel.

What it Does
The IGS 576 BS’s major selling point is its ultra-fast attack time — 20 µS. The IGS 576 BS Ratio buttons allow four different modes of operation: 2:1 Ratio (soft compression); 4:1 ratio (moderate compression); 8:1 ratio (severe compression); 12:1 ratio (mild limiting); 20:1 ratio (hard limiting); S – SLAM, All Buttons In trick mode. SLAM Mode can definitely give a male or female rock vocal track an in-your-face sound that you can’t get anywhere else.

Please note that due to supply issues the 576 may come with black or silver knobs. The standard silver knobs have been hard to source and the folks at IGS would rather ship with different color knobs rater than to make the unit unavailable. if you care about the knob color please touch base with us before you place the order so we can confirm which we have in stock. Thanks!
