The Avantree RC500 is a wireless long range audio receiver incorporating the 

latest “aptX low-latency” technology for CD-like quality sound with virtually no 

audio delay. Full voice menu prompts and easy to read status indicators make the 

RC500 simple to set up and use. The RC500 supports True Wireless Stereo 

(TWS) - purchase two RC500’s to stream audio to 2 separate sets of speakers - 

one set will stream R channel audio and the other L channel.

Step 1. Connect the RC500 to a power source (or compatible USB charger with 

5V/500mA-2A output) via the supplied micro USB cable.

Step 2. Connect your speaker to the RC500 using one of the audio cables 

(optical or AUX/RCA).

Step 3. Slide power switch to “ON” position.

Step 1. Enter the RC 500 into pairing mode (on first use it will automatically 

enter pairing mode and the device “A” LED will flash WHITE quickly).

Step 2. Turn on the Bluetooth on your phone or other device and pair/connect
             with “Avantree RC500”

Step 1. Connect RC500-1 to Speaker 1, then connect RC500-2 to Speaker 2
Step 2. Turn on RC500-1, pair with your phone as above. By default Speaker 1 

      becomes the Left audio channel. Speaker 2 becomes the Right channel.

Step 1. Press and hold the TWS button for 2 seconds on both RC500-1 and 

      RC500-2 to enter TWS pairing mode (this establishes the relationship 
      between the two speakers). The TWS LED flashes WHITE quickly and 
      you will hear “True wireless stereo on”. 

Step 2. Once successfully connected, the TWS LED turns steady and you will 

      hear “Left, right channel connected”.

Step 3. You can now stream stereo music from the two speakers.

NOTE: 1) The two RC500 will not reconnect via TWS, you need to press and hold 

  TWS button for 2 seconds on both RC500’s to use this function again.

2) How to Turn TWS on /off? Press and hold TWS button for 2 seconds, you 

will hear “True wireless stereo on” or “Turn wireless stereo off”

Turn on the RC500, press and hold both “+” and “-” for 5 seconds until you hear a 
voice prompt “Pairing history cleared”. All LEDs turn off then the RC500 will turn on 
again.  This operation clears both the Bluetooth and the TWS pairing history.

To take full advantage of the aptX Low Latency codec (aptX-LL),the paired device 

must also support aptX-LL. If the paired device only supports standard aptX, or 

SBC (low-complexity subband codec), then the connection will default to those 

codecs.

When the RC500 is powered on, it will automatically reconnect with the last 
connected device. The device “A” LED will flash once every 2 seconds. If it fails 
to reconnect after 30 seconds, it will enter pairing mode.

(Note: To use TWS, you need two RC500 devices and two speakers)
9.1. What is TWS?
TWS enables you to use 2 sets of RC500 and speakers for streaming stereo 
music. This may be useful for a studio environment where you need to cover a 
large area and don’t want wires running between two RC500 units.
When using two RC500's as a pair of stereo speakers, the source device (e.g. 
your phone) connects to the first RC500 (RC500-1) which adopts the L channel 
audio. The RC500-1 then connects directly with the second RC500 (RC500-2) 
and streams the R channel audio to it.

Make sure the transmitting device supports aptX low latency (visit 
www.aptx.com for a list of supported devices). Alternatively you can choose
either the Avantree Oasis or our Priva III - both support aptX low latency.

• Please ensure there is a clear line-of-sight between the RC500 and your

audio source (phone) as Bluetooth cannot transmit through walls or other
obstacles.

• Wi-Fi routers, wireless speakers, cordless phones and other wireless 

devices can affect Bluetooth reception. Please relocate your RC500 so it is
not too close to such devices.

• To get the full 164FT/50M range, the transmitting device must also be a 

“class 1” rated Bluetooth device like the RC500.

-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the 

   receiver is connected.

-- Consult the dealer or an experienced radio/TV technician for help.
FCC ID: 2AITF-BTRC-500
To maintain compliance with FCC’s RF Exposure guidelines, This equipment
