Kush Audio UBK Main Gain – No Longer Available

World class, ultra transparent two in/two out active monitor controller

Product Description

The Kush Audio Main Gain is atotally transparent, Class A expandable monitor controller with a small footprint and a revolutionary price point. The Main Gain is a two in/two out standalone monitor controller featuring independent L/R output-muting, a mono switch and tri-color peak/RMS metering.

Features:

  • Standalone, stereo-in/stereo-out monitor controller
  • True mono at the flick of a switch
  • Independent L/R muting
  • Dual-channel tri-Color LED level metering
  • Expansion port on the side for Function Junction and any future modules
  • Ruler flat frequency response, +/- .1db from 2hz-20k, only 3db down at 200K
  • High performance audiophile grade op amp chips with near zero DC offset
  • Extremely low phase shift, only 7.5 degrees at 20k - this spec is not often published, and is related to whether sound is perceived as'sloppy' or 'veiled' vs. 'tight' and 'clear'
  • DC coupled signal path - no electrolytic capacitors

Optional, and not included is also the Function Junction. It is the GainTrain's first expansion module, and attaches to the Main Gain either directly or using a cable for maximum placement flexibility. It expands the system's functionality by adding two additional stereo inputs and outputs (all outputs available simultaneously), talkback with level control and auto program-mute, as well as dual headphone amps with independent level controls and top flight signal path. All Function Junction I/O is via a rear-panel d-sub, allowing the system to be configured for any application.

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.
