## Description

desertcart.com: Avantree Audikast 3 – Bluetooth 5.3 Transmitter for TV Audio via Optical & AUX Outputs Only, aptX Adaptive, Dual Headphone Connection, 100ft Range – Not for HDMI–Only TVs : Electronics

## Features

- [CHECK TV PORTS BEFORE PURCHASE] Works only with TVs that have optical (TOSLINK) or 3.5mm audio OUT ports. Not compatible with HDMI / ARC / eARC ports, TVs that only have HDMI, or with audio–in / headphone–in jacks.
- [EASY SETUP – PLEASE FOLLOW TV SETTINGS] Connect the transmitter to your TV’s optical or 3.5mm audio OUT port and power it via USB, then put your Bluetooth headphones into pairing mode. Make sure your TV audio output is set to “External Speakers” / “Optical” / “Headphones” in the sound menu. If you don’t hear any sound, follow the troubleshooting steps in the included Quick Start guide or our online video.
- [SET TV AUDIO FORMAT TO PCM] For optical connections, please set your TV’s digital audio output to PCM / Stereo in the sound settings. Surround formats such as Dolby Digital / DTS are not supported and will result in no audio.
- [LOW LATENCY WITH COMPATIBLE HEADPHONES] When used with headphones that support aptX Adaptive or aptX Low Latency (e.g. Avantree Aria Me, Audition 3), you’ll enjoy TV audio that is virtually in sync with the picture. With standard Bluetooth headphones, a small delay may be noticeable – this is normal for regular Bluetooth.
