NAD Electronics has announced a new affordable DAC 1 Wireless Audio USB Digital-to-Analog Converter. This new product allows for wireless transmission of audio signals in a uncompressed 16/48 format.

The DAC 1 has been designed to be simple to install and easy to use and no wireless network is needed. The unit’s transmitter plugs directly into the computer’s USB port (PC or Mac) and it serves as a sound card to digitally transmit audio to the hifi system. Measuring a mere 5.3″ x 1.38″ x 2.75″ and weighing less than a pound, the DAC 1 has a range up to 120 feet and can be expected to reach 75 feet in a typical home.

The DAC 1 Transmitter bypasses all the analogue circuitry in the source PC / Mac and transmits directly to the DAC 1 Receiver using the native digital format that helps to ensure the best possible sound. The DAC 1 Receiver then converts the digital signal to an analogue signal before outputting to your stereo amplification system. There is also a coax digital output that allows downstream digital processing. Analogue conversion uses BurrBrown OPAmps and 24/192 DACs with selected passive components in a proprietary circuit.

Specifications:

•Input: USB 2.0
