True peak limiter with all transistor circuitry. Rev A, FET Compressor – 500 series format

SLAM Mode can definitely give a male or female rock vocal track an in-your-face sound that you can’t get anywhere else.

IGS Audio 576 Blue Stripe is a revised version of classic FET compressor, in a compact 500 series form factor.

What it is

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 compressor is equipped with a relay bypass, 2:1 Ratio and Slam Mode accessible on the front panel.

What it does

The 576 Blue Stripe’s major headline point is its ultra-fast attack time –  20 µS.

The Ratio selector allows for 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.

Quick service and reasonable price. Angus was helpful and transparent.20/07/23 Update. I had an issue with some equipment that I purchased from these guys, and true to form, they were supportive and gave me consistent feedback on the progress of my concern. Elliot and Darren were incredibly committed to getting me a satisfactory result. I have recommended Factory Sound to my mates because I actually believe that they will be taken care of.

The only place to buy pro audio gear from. Been coming here for over 20 years, and a lot of the same staff still look after me. Says a lot about their business. The best service, advice and gear every single time. If they don’t have it, they’ll get it for you. No need to worry about pricing, theirs is ALWAYS the best. All the staff go out of their way to help you, and will always get back to you. Cant’ recommend this place enough, 5 stars doesn’t seem like enough.
