What is the main difference between HDMI and Optical audio connections?
HDMI (High-Definition Multimedia Interface) and Optical audio connections are two popular methods for transmitting audio signals from a source device to a receiver or soundbar. The primary difference between the two lies in how they transmit audio signals. HDMI uses a digital signal transmitted over a physical cable, while Optical connections use light to transmit digital audio signals through a fiber-optic cable.
This fundamental difference affects the quality and reliability of the audio signal. HDMI can transmit higher-quality audio signals, including Dolby Atmos and DTS:X, which offer a more immersive listening experience. In contrast, Optical connections typically support up to 5.1 surround sound, which, although still a high-quality format, may not be as immersive as the audio signals transmitted via HDMI.
Is HDMI louder than Optical?
The perception that HDMI is louder than Optical is largely anecdotal and not necessarily supported by technical evidence. The volume of an audio signal is determined by the amplifier or receiver, not the type of connection used. Both HDMI and Optical connections can transmit audio signals at the same volume, assuming the same amplifier or receiver is used.
That being said, some users may perceive HDMI as louder due to the potential for higher-quality audio signals, which can create a more immersive listening experience. Additionally, some devices may have different audio settings or calibration options for HDMI and Optical connections, which can affect the perceived volume.
