Setup Guide

1. Initial Setup and Charging

The Avantree Duet headphones and transmitter are pre-paired from the factory, ensuring a simple plug-and-play experience. Before first use, ensure both headphones are fully charged by placing them on the charging pins of the transmitter dock. The charging indicator on the headphones will show their status.

2. Connecting the Transmitter to Your TV

The transmitter supports multiple audio input options to connect to your television:

• Optical (TOSLINK): For digital audio output. Connect one end of the optical cable to your TV's 'Optical Out' port and the other end to the 'OPT' input on the transmitter.
• AUX (3.5mm): For analog audio output. Connect one end of the 3.5mm audio cable to your TV's 'Audio Out' (headphone jack) and the other end to the 'AUX' input on the transmitter.
• RCA (via 3.5mm to RCA adapter, not included): If your TV only has RCA audio output, use a 3.5mm to RCA adapter with the provided 3.5mm cable.

After connecting the audio cable, connect one of the provided power cables to the transmitter's USB-C port and the other end to a 5V/1-2A USB power adapter (not included) or a TV USB port.

Operating Instructions

1. Powering On and Off

Once the transmitter is connected and powered, simply turn on the headphones. They will automatically connect to the transmitter. To power off, use the power button on each headphone.

2. Volume Control

Each headphone has independent volume controls, allowing users to adjust their listening level without affecting the other listener or the TV's main volume. The system offers a volume boost feature, making audio up to 20% louder than standard headphones, ideal for those with hearing challenges.

3. Clear Dialogue Mode

Activate the 'Clear Dialogue' mode on the headphones to enhance speech frequencies and reduce background noise. This feature is particularly useful for watching content with extensive dialogue, ensuring conversations are crisp and easy to follow.

The Avantree Duet system supports two headphones playing simultaneously from a single transmitter, making it perfect for shared TV viewing experiences.

5. Soundbar Passthrough

The transmitter features an audio passthrough function, allowing you to send audio to both the headphones and an external soundbar or speaker system simultaneously. This means you can enjoy private listening while others can still hear the TV through the soundbar.

Maintenance

Cleaning

To maintain the longevity and hygiene of your headphones and transmitter, gently wipe surfaces with a soft, dry cloth. For ear pads, a slightly damp cloth can be used, but ensure they are completely dry before use. Avoid using harsh chemicals or abrasive materials.

Battery Care

The headphones are equipped with rechargeable lithium batteries. To maximize battery life, avoid fully discharging the headphones frequently. Store the headphones on the charging dock when not in use to keep them charged and ready. If storing for an extended period, charge them to about 50% every few months.

Troubleshooting

No Sound / Intermittent Audio

• Ensure the transmitter is properly connected to your TV's audio output and powered on.
• Verify the input source on the transmitter matches your TV's output (Optical, AUX).
• Check the volume levels on both the headphones and your TV.
• Confirm the headphones are charged and powered on.
• If using Optical, ensure your TV's audio output format is set to 'PCM' or 'Stereo' (not Dolby Digital or DTS).

Audio Delay (Latency)

The Avantree Duet uses 2.4GHz RF technology designed for minimal audio delay (~30ms). If you experience noticeable delay, ensure no other wireless devices are causing interference. Some TVs may have audio processing settings that can introduce delay; check your TV's audio settings for options like 'Game Mode' or 'Bypass' to reduce processing.

Headphones Not Connecting

While pre-paired, if connection issues arise, try re-pairing the headphones to the transmitter. Refer to the full user manual (link below) for specific re-pairing instructions if needed.
