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.

The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

Thank you so much! Vintage King has been so fair and easy to work with. I can't thank you enough. It feels good to trust such a hefty purchase to folks who are so helpful and knowledgeable. Vintage King is a sound designers dream store.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
