These devices handle amplification and source switching, supporting various formats such as Dolby and DTS for surround sound. Most AV receivers now support Bluetooth and WiFi connectivity and offer compatibility with multiple devices like gaming consoles and streaming services. They typically include audio calibration systems that adjust sound settings based on room acoustics. Investing in a quality AV receiver can transform your home movie nights into a cinematic experience.
