American manufacturer Kush Audio are showing the Gain Train, a totally transparent, Class A expandable monitor controller with a small footprint and a revolutionary price point.

The Main Gain, the system’s base module, is a two in/two out standalone monitor controller featuring independent L/R output muting (at last!), a mono switch and tri-color Peak/RMS metering.

The Function Junction is the Gain Train’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.

Each module will carry a $499 MAP, bringing the complete system to the street for under $1,000. Shipping is scheduled for April 2011.
