Thank you for purchasing an ARO-300 Wireless Audio Router. The ARO-300 is the fastest streaming
2.4GHz WiFi router module on the market. It can handle a data rate of up to 300Mbps and its DAC
supports 24 bit/192KHz. Building off of the AR-300’s success, the ARO-300 maintains the open
source app usage while offering superior range as well as 3.5mm line and optical inputs.
The 2.4GHz is one of the most common WiFi spectrums due to its long range. Additionally, the
2.4GHz can navigate through obstacles with less interference.
With the applied proprietary algorithm, the ARO-300 optimizes your bandwidth and produces high
quality audio processing.
