The uTX transmitter makes your PC a part of your NuForce Air DAC wireless audio system. It plugs into one of your computer's USB ports. The transmitter bypasses your PC's sound card and sends a digital audio signal wirelessly to the high-quality digital-to-analog converter inside the NuForce Air DAC receiver module that's connected to your hi-fi system. Each Air DAC transmitter can send audio to as many as four independent receivers (sold separately), so you can play your tunes through multiple audio components.

Product Research


Overview: The NuForce uTX USB transmitter for Air DAC allows you to stream music from your computer USB port to the NuForce Air DAC wireless DAC/receiver (773AIRDAC, sold separately) and your connected home entertainment system. The combination uses SKAA & HPX technology for a wireless audio system with Hi-Fi CD-quality sound.

Windows/Mac Compatibility: The NuForce uTX USB transmitter is compatible with both Windows and Mac computers with a USB (type-A) port, so there's no need to install drivers. The uTX transmitter features a male USB (type-A) connector which plugs into your computer's female USB (type-A) port.

Point-to-Point Wireless Connection: The NuForce uTX USB transmitter can be combined with the NuForce Air DAC wireless DAC/receiver to form a point-to-point wireless audio network; no WiFi "hotspot" needed for reception. Each transmitter can send audio to up to four receivers, and each receiver can connect to as many as four transmitters.

SKAA Wireless Technology: The NuForce uTX transmitter and Air DAC wireless DAC/receiver (sold separately) are based on a new wireless technology known as SKAA. SKAA technology provides seamless operation and a consistent user interface across different SKAA devices, via 2.4GHZ wireless point-to-point transmission. Unlike similar wireless devices, the uTX transmitter and Air DAC (sold separately) do not experience the typical loss in sound quality or interference capability of cell phones and other wireless devices. Rather, the system offers CD-quality sound, virtually no latency, a 49-98' range, and a spread-spectrum technology that detects and chooses from among available frequency spectrums in order to avoid interference. Visit for more detailed information.

HPX Audio Codec: SKAA wireless Technology uses the HPX audio codec from Eleven Engineering Incorporated. The HPX audio codec has several advantages resulting in uncompressed, full-audio bandwidth (20-20k), CD-quality (16bit/48kHz) sound. With HPX audio compression technology, you will be unable to tell the difference between an uncompressed, wired audio source and the NuForce uTX transmitter and Air DAC (sold separately) sending CD-quality sound across the SKAA (2.4GHZ) wireless link.
