Digital audio out Optical cable to RCA

A/V Receiver is a typical component within Home Theatre System. The basic functionality is to receive and amplify an audio signal and allow it to pass through the video signal from other A/V devices to the TV.
HDMI cable
- Antenna cable
- HDMI cable with ARC (Audio Return Channel)
If your Home Theatre System, TV, and the HDMI cable support ARC, it means the TV can transmit sound to Home Theatre System. When you connect the TV to the Antenna/Cable directly (without Set Top Box, it will allow you to hear the TV sound through speakers connected to Home Theatre System.
If you are using Set Top Box, you will need to output the sound from Set Top Box to Home Theatre System.
When connecting a BRAVIA Sync-compatible digital audio system with Audio Return Channel (ARC) technology, find the HDMI jack (socket) that carries the "ARC" mark (HDMI IN 1 or HDMI IN 2, depending on your model/ region/ country) and connect to it with an HDMI cable. However, if connecting a system that is not BRAVIA Sync-compatible or ARC capable, an additional audio connection via DIGITAL AUDIO OUT (OPTICAL) is necessary.
If connecting a system that is not compatible with Control for HDMI or ARC, an additional audio connection is necessary:
HDMI + Optical Audio cable
- Audio cable (optional) - Optical Audio cable
- HDMI cable
HDMI + Mini-plug audio to RCA cable
- Audio cable (optional) - Mini-plug to RCA/Composite Audio cable
