Doesn’t work/not recommended for:
• Bypass / pass through function NOT supported. You may consider Oasis Plus for this feature.
• Volume Control only works in AUX mode NOT in SPDIF (optical) mode.
• If you need to leave it on continuously, Avantree Audikast Plus without built-in battery is recommended.
• When works with Beats headset, the headset volume control does not work.
• Works as EITHER a transmitter or receiver - NOT both simultaneously.
• For TV optical output - set audio format to PCM, as Dolby DTS is not supported.
• Not compatible with ANY RCA output on the back of the AV Receiver / Amplifier.
• aptX Low Latency cannot be achieved in dual link.
• If one of your headphones is Plantronics Backbeat pro II or Beast solo 3, then dual link is not recommended.
• When using the transmitter, the TV internal speakers might not work or may become muted. This is TV dependent.
• For non-aptX-LL supported headphones / speakers, TC417 will work using SBC or aptX codec with 70-200ms latency, though Lip-sync delay may be noticed by sensitive users. To achieve low latency effect, your device also has to support aptX Low Latency, we recommend using Avantree Torus / AS9P / AS90P / AS90T / AS90TA.
