Install the Transmitter
- Make sure your amplifier is off. Connect the transmitter to your amplifier’s speaker output terminals with the provided 6-foot speaker wire, matching polarities. Or connect your transmitter to the amplifier’s RCA output ports with RCA cables (not included).
- Connect the supplied AC adapter (9V, 1.3A) to the DC IN 9V jack, then plug it into a standard household outlet.
Install the Receiver
- Connect the rear speakers to the receiver with speaker wires, matching polarities.
- Connect the supplied AC adapter (15V, 4A) to the DC IN 15V jack, and then plug it into a standard household outlet.
Note:
-
Make sure the exposed tips of the speaker wires do not touch each other, and make sure they are fully inserted into the terminals.
-
This speaker kit is designed for connecting to your amplifier surround speaker terminals only.
-
For speaker wires that have proprietary connectors, you may need to strip the end of the wires to allow connection to the receiver.
However, check with the speaker manufacturer before doing this, as it may void the warranty. -
When the RCA cables are connected, audio input from the speaker terminal will be mixed.
-
Unplug the AC adapters from the AC outlet before unplugging it from the transmitter or receiver.
-
Use the supplied AC adapters only. Using an AC adapter not designed for this product may cause damage.
Place the Transmitter and Receiver
The transmitter and receiver must be placed within 100 feet for proper
operation. They can be placed horizontally on a flat surface, vertically in
the provided stands, or mounted on a wall using the mounting holes on the
bottom. 
Note : If you need to mount the receiver on a wall, install it against
the wall in such a way that the ventilation slots are not blocked.
To optimize the reception performance, place the transmitter and receiver in
the same orientation.
Use Your Speaker Kit
- Once the AC adapters are connected, the receiver LEDs light green. The speaker kit enters standby mode.
- Tum on your amplifier and then play the audio or video source through your amplifier.
- When an audio signal is detected by the transmitter and the transmitter signal is detected by the receiver, the speaker kit will automatically go into active mode. The transmitter and receiver LEDs will both turn blue.
Note: After powering on, if there is no signal input within 17 minutes,
the speaker kit enters standby mode.
Change the Channel
If you experience any interference, press and hold the M button on both units.
The units will then automatically pair. Adjust the Volume Balance
- Power on the transmitter and receiver, and then turn on the amplifier and adjust it to your normal listening level.
- Adjust the receiver’s VOL +/ control to balance the front and rear speaker sound level. This step is only necessary during the first-time installation of the speaker kit with your system.
- After balance setup, simply use the volume control on your amplifier to adjust speaker volume during playback.
Optimize Your Surround Sound
Many surround-sound systems let you adjust the delay between the front and
rear speakers. To optimize your setup, adjust the rear speaker delay response
by about 20 milliseconds.
