Positive Grid BIAS Gate EX – No Longer Available

Professional noise gate & downward expander plug-in (Mac/PC)
MFR# 667-100-012-878

Product Description

Bias GateEx is a pro-quality noise gate and downward expander with precision graphic displays and advanced parameter controls.

GateEx's noise gate removes signals below an assignable level, and is perfect for isolating one type of instrument from another, and for removing unwanted residual noise.

GateEx's downward expander allows expansion of dynamic levels by lowering gain level in quiet passages.


  • GateEx can be used as both a noise gate and a downward expander.
  • As a noise gate, it's perfect for isolating one type of musical instrument from another, as well as reducing unwanted residual background noise.
  • When used as a dowward expander, it can increase the apparent dynamic range of recordings.


This professional cross-platform noise gate and downward expander plug-in includes Audio Units, RTAS/AudioSuite, and VST formats, and can be used within most popular professional audio editing hosts on Mac & Windows systems — such as Peak, Digital Performer, GarageBand, Live, Logic, Premiere, Pro Tools, Sonar, Sound Forge, and many others.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
