Onkyo TX-SR333 offers multi-zone playback which allows you to play different input sources in 2 different rooms.

Zone 2

• Audio Line Output: If you have a dedicated integrated amplifier for Zone 2 you can connect it to the a/v receiver via line outs by sending fixed signal and then control volume on the Zone 2 amplifier.

Audio

• Analog Line Inputs and Outputs: There are 7 line inputs and 1 line output for analog audio connection.
• Digital Inputs: 1 optical input and 2 coaxial inputs are available for digital audio connection.
• Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel.

Video

• HDMI:
Inputs: 6   Outputs: 1
8K Inputs: 0
• Composite Video: Connect you VCR, Laserdisc player and other old video equipment with composite video cables.
Inputs: 4   Outputs: 1
• Component Video: Component video connection gives you the higher quality video compared to the composite video connection. So in case your old DVD player and other equipment do not have an HDMI output but have Component video output use this connection over the composite one.
Inputs: 1   Outputs: 1

Front A/V Inputs

• Composite Video, RCA audio
