WR385 RX Receiver:
Input interface: 5.8G RF wireless lossless transmission
Output interface: fiber + coaxial +AUX
Button operation: pairing transmitter and mute operation through the button
Indicator: Indicates the 5.8G wireless connection status and power amplifier working status
Power input: DC 5V~1A adapter power supply

WR385 RX Amplifier:
Input interface: 5.8G RF wireless lossless transmission
Output interface: AUX stereo active output +2 channel 40 watt digital power amplifier output
Button operation: pairing transmitter and mute operation through the button
Indicator: Indicates the 5.8G wireless connection status and power amplifier working status
Power input: DC 12V~20V/2A adapter power supply
Automatic power amplifier function: when the transmitter has no audio input or shutdown for more than 10 seconds, the receiver will automatically turn off the power amplifier to reduce heat and consumption; When the transmitter resumes the signal input, the receiver will automatically turn on the power amplifier and work normally.

Transmitter operation instructions:
INPUT button: short time for cyclic switching input source: OPT->COX->AUX->USB;
(Automatically detect U disk insert and play automatically, if no U disk is inserted, switch automatically skip USB mode)
Long time for soft shutdown (then short press to start)
VOL- button: short time for the “previous song” function when the U disk is playing (short press in other modes is invalid)
Volume reduction function when held for at least 3 seconds (Long press in any mode)
VOL+ button: Short time is the “next song” function when the U disk is playing (short press in other modes is invalid)
Volume increase function when holding for at least 3 seconds (this works in any mode)

LED indicator description:
5.8G: Steady red indicates that the connection is normal, and blinking indicates that the pair is waiting
OPT: If the indicator is steady blue, the optical fiber input mode is displayed. If the indicator is blinking, the signal input is displayed
COX: When the indicator is blue, the indicator is in coaxial input mode and the indicator is in signal input mode
AUX: Blue, if the steady on is in AUX input mode, and if the blinking is in signal input mode
USB: When the indicator is blue, it is in USB Play mode, and when the indicator is blinking, it indicates that there is signal input

Interface:

High turn bottom input line connection: NC empty foot, GND ground (black line) is not required to be connected, some power amplifiers may be connected to the black line to jointly eliminate noise. Red and white wire pairs should be connected to the output of the left and right channels (red positive, white negative)

Receiver operation guide
ON/OFF button: hardware power switch, press to start, eject to shut down;
LINK button: Short press to mute the power amplifier and enter the low power mode, then short press to restore the working state and long press for at least 3 seconds to pair with the transmitter. During the pairing process, the “5.8G” indicator will flash several times, and after successful pairing, the indicator will turn to steady on and emit a “beep” sound (Any time long press is pairing operation, only the first time you need to pair. Or it may have been paired at the factory)

LED indicator description:

5.8G: Steady blue: 5.8G wireless connection is normal, blinking: waiting for pairing

ERROR: Steady blue: The power amplifier enters the protection mode, and the power amplifier works normally

• Common problems and solutions
• Can not boot
  • Select a qualified adapter to power on according to the specifications. It is recommended to select a 5V 1A adapter with output voltage, and select a 2A adapter with output voltage of 12V to 24V at the receiving end of the power amplifier (do not overvoltage mixed connection).
  • Turn on the switch.
  • Check whether the power cable is normal.
• Unpairing
  • Ensure that the antenna of this product is installed and tightened.
  • Long press the LINK button to repair
  • Ensure that the product is in pairing mode and that no more than 3 devices are connected.
  • Ensure that the product is within 30 meters of the pairing device (close to the connection first).
  • Delete all connected Bluetooth device records from the phone or tablet device, restart the phone or tablet to restore the device’s Bluetooth driver, and reconnect the device.
  • When the distance is too short or the connection is not successful, please check whether there is too much wireless device interference around the environment (such as WiFi signal, wireless mouse, other 5.8 devices, etc.).

About current noise

• 1. Please check whether the audio cable is improperly connected and re-plug the rotary audio cable connector;
  2. If the power cable and audio cable are connected to the same device, please connect the power cable to the main charge or replace the power supply to avoid interference from the common ground power supply.
  3, due to the weak anti-interference ability of some audio source equipment, other wireless signals are imported into the audio source along the audio line, causing interference. Please change the audio cable with shielding or use another device to test.
  4, some audio sources informal standard transfer, please replace the audio source test.
  NO sound
  • Ensure that the device is properly connected to the product and that the output/input mode is set correctly.
  • Check the volume of each connected device.
