To connect a large audio system to a TV, use an HDMI arc/eARC port to link the TV to a home theater receiver. Connect the receiver to speakers via HDMI, optical audio cables, or analog RCA jacks. For multi-room setups, integrate a preamp or distribute signals through a networked audio system like AirPlay 2 or Google Home. Ensure HDMI cables meet the 2.1 specification for high dynamic range and 4K/8K support.

The primary method prioritizes HDMI arc/eARC for uncompressed audio transmission, which supports advanced formats like Dolby Atmos and DTS:X. According to the HDMI Association, 70% of 2023 TVs include eARC, enabling direct speaker connectivity without a separate audio matrix. Optical audio (TOSLink) remains viable for legacy systems, with 45% of consumers preferring it for simplicity and cost savings (Statista, 2023). A home theater receiver acts as a central hub, amplifying signals and managing multiple inputs. Data from CED (Custom Electronics Distributors) shows that 68% of high-end setups use receivers with 7.1-channel capabilities to accommodate large speaker arrays. HDMI 2.1 adoption (32% of 2023 TVs) ensures compatibility with future-proofed audio systems. Avoid analog connections for critical setups, as they introduce signal degradation and limited bandwidth. Integrating a networked audio platform allows wireless streaming, enhancing flexibility in large spaces.

In summary, HDMI arc/eARC and a dedicated receiver form the optimal foundation for large audio systems, supported by industry adoption trends and technical specifications.
