LG 9QK DMR3 User Manual
Model Name : R3
Product Description.
The Module is an OEM module (35x35mm) based on the SMSC DARR83. It is an uncompressed
wireless digital audio transceiver operating in the 2.4GHz, 5.2GHz and 5.8GHz bands. The wireless
audio link supports up to 4 stereo audio streams and comes together with additional features such as:
data encryption, pairing functionality, bi-directional control data messages, low power audio snooze
mode, WLAN detection and Automatic Frequency Allocation. The DARR83 chip itself provides the
basic functions of Audio Processing and buffering, Data Link Layer and Physical Layer. The module
integrates all functionality for a wireless digital audio connection, comprising:
