If you're planning a system that uses two or more JL Audio VXi amplifiers, you may want their VXi-HUB network interface as well. The VXi-HUB lets you control all the channels of sound from one application on your computer, phone, or tablet. The VXi-HUB provides digital network connectivity for one master VXi amplifier and up to five slave VXi amps, so you can use the JL Audio TüN™ software to synchronize all digital sound processing controls and presets. Up to two VXi-HUBs can be daisy-chained to network up to ten VXi amplifiers in a mega-size sound system.
