How to connect a TV to a stereo amplifier
Match a documented TV audio output to a compatible amplifier input, then check the audio format and volume controls. HDMI ARC or eARC, optical and analog outputs offer different routes. A working cable is only part of the setup: the selected TV output, amplifier source and app settings must agree too.
What is a DAC, and do you need an external one?
A DAC converts digital audio into an analog electrical signal. That function may already be inside your computer, amplifier or another playback device. An external DAC is useful when it supplies a connection or capability your system lacks. Identify the missing function or actual problem first; a digital source alone does not require another box.
Hi-fi connections explained: what plugs into what?
Match the signal and direction at both ends before choosing a cable. An output must feed an input designed for that signal: analog line, phono, speaker-level or a compatible digital format. RCA, XLR and USB describe connectors, not a complete compatibility promise. When the signal itself must change, you need the appropriate conversion function, not just plugs that fit.
