ELECTRONICS MECHANIC - CITS

Home theater receivers include two types of digital audio-only connections: optical and coaxial. Use these to
connect audio from most DVD players, Blu-ray Disc players, and HD and 4K Ultra HD TVs. Some CD players also
provide one or both of these output options.
These connections access two-channel stereo and standard Dolby Digital and DTS surround sound signals.
These connections cannot pass enhanced surround formats, such as Dolby Digital Plus, TrueHD, Atmos, and
DTS-HD Master Audio or DTS:X. Those are only accessible from an HDMI connection.
Analog Audio Input Connections

Most audio is available digitally. Still, many devices either use analog exclusively (such as vinyl record turntables,
audio cassette decks, and VCRs) or provide it as an alternate audio connection option (using RCA style jacks and
cables) on devices such as TVs, cable and satellite boxes, and DVD and Blu-ray Disc players.
AM/FM Radio Antenna Connections

Another audio source included in home theater receivers is radio reception. Most home theater receivers
provide connections for AM and FM antennas. However, some home theater receivers only provide FM antenna
connections as these receivers may not include an AM tuner.
Speaker Connections
You can’t hear the sound from a home theater receiver unless you connect some speakers.

When connecting speakers, match the speaker terminals with the speaker placement. This means connecting the
center speaker to the center channel speaker terminals, the left front to the main left, the right front to the main
right, the surround left to the surround left, and the surround right to the surround right.
