Proficient’s ZERO wireless multizone audio system is designed to transmit audio up to 90 feet throughout a home using 2.4 GHz RF technology. ZERO transmitters support up to 8 receivers and have connections for three analog audio channels plus an optical audio input – and can transmit all channels simultaneously. Proficient says that transmitting all inputs enables the use of one transmitter to send “left and right” audio for “Zone 2” or “rear surrounds” (without latency being an issue) as well as audio to a subwoofer for a home theater system.
Proficient ZERO wireless amplified receivers include a built-in 35-watt x 2 digital amp with stereo speaker outputs, a stereo 3.5mm line output, a mono 3.5mm output (for use with a third analog audio channel), an optical input, and a stereo 3.5mm input (for use with a local source, such as a TV). The analog, digital, or local source inputs can be selected with the included IR remote. Proficient ZERO wireless preamp receivers will also be available in the near future.
ZERO extenders will use 5.8 GHz RF to extend the range of the system to 190 ft.
