It is ideal for adding multiroom capability to an existing audio system; adding surround speakers to a home theater system without running speaker wires; distributing music to anywhere in the home from a computer; and for many other applications.

The WEM-1 has an operating range of up to 70 feet. It provides a variety of connection options, including line- and speaker-level outputs, to accommodate a wide range of audio source components and A/V receivers.

The receiver/amplifier unit features a 50-watt-per-channel amplifier and includes a subwoofer output. It provides five equalization curves that are tailored for use with select JBL loudspeakers; it also provides an unequalized bypass setting.

The receiver/amplifier also has a local input, allowing the user to directly connect a portable device or other audio source to it at a remote location.

The JBL On Air WEM-1 Wireless Expansion Module will be available in September 2008 at a suggested retail price of $359.
