The HRT AirStreamer is a high performance, two piece wireless audio solution that is ideal for situations where the user and the audio system are separated and a USB cable run is impractical or undesirable.
The Wireless Master is a small, USB powered and connected ‘transmitter’ that links seamlessly with the AirStreamer receiver.
When connected to any USB host (computer, tablet, smartphone, or similar) the Wireless Master will present itself as a USB Audio Class 1.0 device and the enumeration process is virtually automatic for any modern operating system. Utilizing native, UAC1 drivers, no software is needed and setup is simply informing the host that the AirStreamer is your intended audio destination.
Equipped with a removable SMA connected antenna, the range can be extended beyond the normal 20 meter limit by simply replacing the included antenna with an optional, higher gain, version.
Designed with extremely low power as an important goal, the Wireless Master can be used with a large range of hosts including many smartphones and tablets. As a fully compliant USB device, an ultra-low power sleep state is automatically used when the host instructs the Wireless Master to enter sleep. With its optimized RF design, the Wireless Master will run for extended periods of time without consuming excessive power from portable hosts.
With an included USB A to mini B cable which is detachable, the Wireless Master can be placed conveniently and with its flexible connection, even handheld hosts such as smartphones make for practical parings.
The AirStreamer receiver contains a high performance RF (radio frequency) front end, a 24 bit differential mode DAC, along with a sophisticated analog reconstruction filter and output amplifier. Capable of moving high resolution audio (24 bit depth) at sample rates which include 32 kHz, 44.1 kHz, and 48 kHz, the AirStreamer is ideal for music, audio-video, gaming, professional audio, and commercial applications.
Housed within a robust extruded aluminum enclosure, and equipped with RCA style analog audio outputs, the AirStreamer is easy to setup and use with a single step pairing process. A front panel LED allows for a quick determination of the mode of operation (locked and streaming, locked and not streaming, pairing ready, and not paired).
Power for the AirStreamer is via an included AC mains power supply and a 2 meter USB A to mini B cable. Simply connect the AirStreamer’s line level output to the analog input of any audio system, and you are ready to enjoy high performance audio, without the need for either a wireless network or any complex WiFi setup steps.
The AirStreamer uses a look ahead frequency hopping approach that will automatically accommodate changes based upon other RF devices that might compete for spectrum. Latency is managed and low so that the AirStreamer can be used in audio-video applications without any concern for ‘lip sync’ issues.
With a level of performance that far exceeds Bluetooth and other low quality wireless interfaces, and without the complexity of network based wireless solutions, the AirStreamer is the ideal solution for any audio application.
