TV (versions 9-12 and Google TV, If you've just purchased a Sony theater or are planning to upgrade, this guide will save you time and nerves.
1.Preparation: What will be needed to connect
Before you start connecting devices, check for all the necessary components, which depends on the way you can use the connection.
- π Cables: HDMI 2.0/2.1 (recommended ARC/eARC) Optical cable (TOSLINK) for digital audio audio audio cable 3.5 mm (AUX) for analogue Coaxial connection RCA (It is rarely used in older models)
- π± Remote: from Xiaomi TV and Sony cinema (may need synchronization).
- π Power supply: Make sure both devices are connected to the network and on.
- π Documentation: Instructions for the cinema model (subscribes supported sound formats).
If you use a wireless connection (Bluetooth or Wi-Fi), no additional cables are needed, but check if your Sony theater supports these technologies. HT-Z9F or HT-A5000 Bluetooth is available, and budget options are HT-S350 may require an adapter.
