On the back of the ZP120 you’ll find more than just speaker jacks. There are several ports available that extend the functionality of your player. Here’s what they all do.
A. The ZP120 comes with 2 CAT5 Ethernet jacks enabling you to hard-wire the player to your home network if you don’t have wi-fi. Remember, too, that your first Sonos device (in the absence of the ZonePlayer Bridge) must be physically connected to your wireless router. The second port allows you to extend network connectivity to another device like a computer or NAS.
B. Use a standard RCA cable to connect a CD, DVD or MP3 player, TV or radio to the analog line-in. Note: The ZP120 does not support direct connection of an iPod or iPhone. For this you need a Sonos Dock or Apple AirPort Express.
C. You can attach a powered sub-woofer via the line-out with a regular RCA cable. The 120 will automatically detect the connection and adjust the crossover frequency.
D. The ZP120 has both left and right speaker terminals. Connect your speakers to the spring binding posts using high-quality speaker wire, or if you’re in North America, you can also use banana connectors.
E. You can switch the voltage to either 120 or 240 volts.
