Aperion launches the 2nd generation Zona Home Audio Link (HAL) system-- a cable-free transmitter and receiver combination.
It connects to virtually every audio source through either USB or 3.5mm jack, streaming uncompressed 16bit/48kHz audio to up to x3 simultaneous channels.
A single HAL transmitter can feed what Aperion says is an "endless number" of additional receivers, with a signal range of around 30m.
The package includes 1 transmitter and 1 receiver (with additional receivers available separately), as well as RCA stero and USB extention cables.
