QWHDW20RWireless Systems

Getting Started 1. Connect the DW 20T inputs to an original audio source such as a mixer or media player, then connect the outputs of the DW 20R to a destination such as a mixer, amplifier, or active speaker. Leave the amp or speakers turned off for now. 2.Connect the power adapters to each unit. They will power on automatically and their PAIR buttons will blink slowly to indicate standby mode. 3.Press and hold the PAIR button on the DW 20T for 4 seconds. The LED ring will flash rapidly to indicate that it is trying to pair, and will continue trying for up to 30 seconds. 4.Within 30 seconds of initiating the DW 20T for pairing, press and hold the PAIR button on the DW 20R for 4 seconds as well. Its LED ring will flash rapidly. 5. When successfully paired, the LED rings on both the 20T and 20R will light solid (not flashing). If either unit’s LED ring flashes slowly, this indicates that pairing was unsuccessful. Make sure both units are free of obstructions and are within 100 feet / 30 meters of each other. 6.After all audio and power connections have been made, power on the amplifier or active speakers. Pairing multiple DW 20R units with a DW 20T 1. Connect the DW 20T and the first DW 20R as described in ‘Getting Started’ (hold each PAIR button for 4 seconds). 2.On the second DW 20R unit, hold the PAIR button for 4 seconds to activate pairing, then let it search for 30 seconds. The pairing function will time out after 30 seconds and the LED will blink slowly. 3.Press the DW 20T PAIR button for 4 seconds, and then press the second DW 20R unit’s PAIR button for 4 seconds. Both DW 20R units will now be connected to the same DW 20T. 4.Note - holding the PAIR button for 10 seconds on the DW 20T will clear the memory of connected DW 20R units. (1) PAIR button enables the unit to become available for pairing by pressing and holding for 4 seconds. The LED ring will indicate the current status. See the Getting Started section for details. (2) LEVEL knob adjusts the volume of the signal sent to the output jacks. (3) SIGNAL LEDs light when the DW 20R receives an audio signal from the DW 20T. (4) DC INPUT socket accepts the included power adapter. (5) STEREO/MONO switch determines whether the outgoing wireless audio signal is stereo or mono. (6) LEVEL knob adjusts the sensitivity of the inputs. (7) SIGNAL LEDs light green when signal is present at the inputs. The LEDs light red when the incoming audio signal clips the inputs. If this happens, lower the output level of the source audio. (8) OUTPUT jacks send a line-level audio signal to another audio device (mixer, amplifier, etc.) via balanced XLR or unbalanced ¼" TS cables. (9) INPUT jacks accept audio signals via balanced XLR or unbalanced ¼" TS cables.
