AeroLink - Easily integrate wireless Bluetooth streaming into a new or sound system. The included rack-mount kit makes installation quick and easy. Stream audio directly from your Bluetooth-enabled phone, tablet, or computer to your sound system. No messy cables, broken dock connections, or finding suitable input on a confusing sound system. It's one of the few models available where you can use up to 5 Bluetooth® Receivers at one location. Just pair and play - that simple. The AeroLink comes with a Rack Mount Kit to secure it into your audio rack and easily plugs into your sound system using the included red/white RCA cable. Once in place, never worry about faulty cables, docks, or confusing inputs again.

When you are finished, just walk away - distance will disengage the pairing. You can also press the blue link button again to reset the pairing. Bluetooth technology is built on a ‘handshake’, meaning that once a device is paired to the AeroLink, another device cannot cut in until the AeroLink (or the paired device) releases the link - meaning there won’t be any interruptions from other Bluetooth devices in the room.
