Frequently Asked Questions - CBC70 Aukey

How to use the BR-O8 in receiver mode (RX)?

Connect the audio output of the BR-O8 to your audio equipment (headphones, speaker) via a 3.5 mm, optical, or RCA cable. Slide the RX/TX switch to RX and the power switch to BT. Press the pairing button for 3 seconds, then select 'AUKEY BR-O8' from your audio source (smartphone). The 'A' or 'B' indicator lights up solid white.

How to switch to transmitter mode (TX)?

Connect the audio input of the BR-O8 to your source (TV, computer) via a 3.5 mm or optical cable. Set the RX/TX switch to TX and the power switch to BT. Press for 3 seconds to pair, then enable Bluetooth on your headphones or speaker. Automatic pairing. Solid green indicator signals connection.

How to use bypass mode?

Connect an audio source to the input (3.5 mm or optical) and audio equipment to the output. Set the power switch to BYPASS. Press the Ⓞ button to choose 'AUX' or 'OPT'. The sound is amplified without wireless transmission.

What cables are included?

The BR-O8 comes with: a micro-USB cable, a 3.5 mm audio cable, a 3.5 mm to RCA audio cable, and a Toslink optical cable.

What is the Bluetooth range?

The maximum range in open space is 50 meters. Beyond that, the BR-O8 disconnects and attempts to reconnect automatically if you return to the area within 5 minutes.

How to delete the paired devices list?

Press and hold the ⓧ button for 8 seconds in RX or TX mode. The list is cleared and the device returns to standby mode.

Can I connect two Bluetooth devices at the same time?

Yes, the BR-O8 supports dual connection. After pairing the first, repeat the procedure for a second. The display shows 'A' and 'B' solid white. Only one device can transmit audio at a time.

Which audio codecs are supported?

The BR-O8 supports SBC, aptX, and aptX Low Latency. The codec is automatically selected based on your Bluetooth device's capability. aptX Low Latency offers the best latency/quality compromise.

How to charge the BR-O8?

Use the included micro-USB cable and plug it into a standard USB power source (5 V). There is no internal battery: the device must be plugged in continuously.

What to do if the sound is out of sync with the video?

Ensure your source device and receiver support aptX Low Latency (LL). If the 'LL' indicator does not appear, select a faster codec or reduce distance. aptX-LL mode reduces latency to about 40 ms.

• When simultaneously connected with two devices, the BR-O8 can only accept audio input from one device at a time

Transmitter Mode (TX Mode)

1. Connect one end of the included 3.5mm audio cable or Toslink optical cable to the 3.5mm audio input or optical input of BR-O8. Connect the other end to your audio source device (TV, computer, DVD player, CD player, or MP3 player) that doesn't have wireless function
2. Connect the BR-O8 to a power source with the micro-USB cable
3. Slide the RX/TX switch to "TX" position. Then slide the Power/Mode switch to "BT" position
4. Tap and hold ^✝ for 3 seconds, and the BR-O8 will enter pairing mode with the square connection status indicator flashing green rapidly

5. Activate the pairing function of your wireless-compatible audio device (like wireless headphones or speaker). Keep your device close to the BR-O8 and they will pair automatically

6. Once paired, there will be a solid white "A" indicator on the display

7. If you want to pair with a second wireless-compatible audio device for dual device connection, repeat steps 4 & 5 with that device
8. Once paired, there will be solid white "A" and "B" indicators on the display

Note for Transmitter Mode

- If your TV, DVD player, or CD player has left & right channel RCA outputs (colored white and red respectively), you can use the included RCA cable to connect instead

Notes for Receiver & Transmitter Modes

• When you turn on the BR-O8, it will automatically reconnect to the last-paired device
  • The BR-O8 will exit pairing mode after 1 minute
• To clear the pairing list, tap and hold ⏻ for 8 seconds in RX or TX Mode
• The maximum wireless operating range is 50m (164ft). If you exceed this range, the BR-O8 will disconnect from your paired device. The connection will be re-established once you re-enter the wireless range within 5 minutes

Bypass Mode

1. Connect an audio source device (TV, computer, DVD player, CD player, or MP3 player) to the BR-O8 3.5mm audio input or optical input with the included 3.5mm audio cable or optical cable
2. Connect your wired audio equipment (wired headphones, speaker, or stereo system) to BR-O8 3.5mm audio output or optical output with a 3.5mm audio cable or optical cable
3. Connect the BR-O8 to a power source with the micro-USB cable
4. Slide the Power/Mode switch to "BYPASS" position
5. Tap Ⓞ to select the audio input mode "AUX" or "OPT"
6. Once connected, you can enjoy boosted sound from your wired audio equipment

Note

- Only one of each cable type is included, so you will need to use two different cable types to connect your two devices to BR-O8 (or supply a second cable if you want to use two the same). If your connected audio equipment has left & right channel RCA outputs (colored white and red respectively), you can also use the included RCA cable to connect

Bluetooth Audio Codecs (for Receiver and Transmitter Modes)

Bluetooth audio codecs encode digital audio data for transmission over Bluetooth connection and decode it at the other end. SBC is a standard codec for Bluetooth audio streaming. aptX offers lower latency (less audio delay when watching videos or playing games) and improved audio quality. aptX Low Latency has the best performance of the three with much lower latency. BR-O8 supports all three codecs, so the codec used will be the best one your connected Bluetooth device supports.
