Setup
Follow these steps to set up your Avantree TC419:
- Power Connection: Connect the TC419 to a power source using the provided USB cable. You can use a USB wall adapter (5V/500mA-2A, not included) or a USB port on your TV/PC. Ensure a stable power supply for optimal performance.
- Select Mode: Use the TX/RX switch on the unit to select the desired mode (Transmitter or Receiver).
- Audio Connection: Connect the TC419 to your audio source (in TX mode) or audio output device (in RX mode) using one of the following cables:
- Optical Cable: For digital audio output from TVs, soundbars, etc.
- 3.5mm AUX Cable: For devices with a standard headphone jack or AUX output/input.
- RCA Cable: Use the provided 3.5mm to RCA adapter cable for devices with red/white RCA audio ports.
- Power On: Press the power button on the front of the TC419 to turn it on.
Operating Modes
The Avantree TC419 supports three primary operating modes:
1. Transmitter (TX) Mode
In TX mode, the TC419 sends audio wirelessly from a non-Bluetooth device (e.g., TV, PC, CD player) to Bluetooth headphones or speakers. This is ideal for private listening or adding Bluetooth capability to older audio equipment.
- Set the TX/RX switch to TX.
- Connect the TC419's input to your audio source (e.g., TV's optical out, headphone jack).
- The TC419 will automatically enter pairing mode (LED flashes blue/red).
- Pair with your Bluetooth headphones/speakers.
2. Receiver (RX) Mode
In RX mode, the TC419 receives Bluetooth audio from a smartphone, tablet, or other Bluetooth-enabled device and outputs it to a non-Bluetooth audio system (e.g., home stereo, wired speakers, car stereo).
- Set the TX/RX switch to RX.
- Connect the TC419's output to your audio system's input (e.g., AUX-in on a stereo).
- The TC419 will automatically enter pairing mode (LED flashes blue/red).
- Pair your smartphone/tablet with the TC419.
3. Pass-through (Bypass) Mode
This mode allows you to simultaneously output audio to both a wired speaker system and Bluetooth headphones. Audio from your source (e.g., TV) passes through the TC419 to your wired speakers while also being transmitted wirelessly to your Bluetooth headphones.
- Ensure the TC419 is in TX mode.
- Connect your audio source to the TC419's input.
- Connect the TC419's RX Output to your wired speaker system's input.
- Pair your Bluetooth headphones with the TC419.
Pairing Instructions
To connect your Avantree TC419 with a Bluetooth device:
- Enter Pairing Mode:
- If the TC419 is new or has been reset, it will automatically enter pairing mode (LED flashes blue and red alternately).
- If already connected, press and hold the Bluetooth button (&B) on the TC419 for 3 seconds until the LED flashes blue and red.
- Activate Pairing on Your Device: Put your Bluetooth headphones, speaker, or smartphone into its pairing mode. Refer to your device's user manual for specific instructions.
- Connect: Place the TC419 and your device close to each other. They should connect automatically within a few seconds. Once connected, the LED on the TC419 will turn solid blue.
- For Second Device (TX Mode): To connect a second pair of headphones in TX mode, press the Bluetooth button on the TC419 again to enter pairing mode, then put the second headphones into pairing mode.
Maintenance
To ensure the longevity and optimal performance of your Avantree TC419:
- Keep the device dry. Avoid exposure to moisture or liquids.
- Clean the device with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Store the device in a cool, dry place when not in use.
- Avoid extreme temperatures.
- Do not attempt to disassemble or modify the unit, as this will void the warranty.
Troubleshooting
If you encounter issues with your Avantree TC419, please refer to the following common problems and solutions:
- No Sound or Intermittent Audio:
- Ensure all cables are securely connected to the correct input/output ports.
- Verify the TC419 is in the correct TX or RX mode.
- Check the volume levels on both the TC419 and your connected audio device.
- Ensure the power supply is stable. If powered by a TV USB port, try connecting to a dedicated USB wall adapter for consistent power.
- Move the TC419 closer to the connected Bluetooth device to improve signal strength and reduce interference.
- Clear the pairing history on both the TC419 and your Bluetooth device, then re-pair.
- Cannot Pair Devices:
- Ensure both the TC419 and your target device are in pairing mode (LED flashing blue/red on TC419).
- Disable Bluetooth on any other nearby devices that might be trying to connect.
- Power cycle both the TC419 and your Bluetooth device.
- Ensure your device is not already connected to another Bluetooth transmitter/receiver.
- Lip Sync Delay (Audio Lag):
- Ensure both the TC419 and your headphones/speakers support aptX Low Latency (aptX LL) or FastStream (FS) codecs. If only one device supports it, the connection will default to a lower latency codec like SBC, which may introduce noticeable delay.
- Some TVs may have internal audio processing that introduces delay. Check your TV's audio settings for options like "PCM" or "Bypass" for optical output.
