Cinema 400 - Adding a Wired/Second Subwoofer

The Cinema 400 features a "Sub Out" jack on the back of the sound bar that will allow you to wire an additional powered subwoofer of your choosing. You can use this wired subwoofer in replacement of, or in addition to, the wireless subwoofer that the system comes packaged with.

TO CONNECT AN ADDITIONAL POWERED SUBWOOFER:

1. Use a single RCA cable (or standard subwoofer cable) to connect the additional subwoofer to the sound bar
2. Plug in one end of the cable into the "SUB OUT" jack on the back of the sound bar
3. Plug the other end into the RCA Line In or LFE jack on the back of the powered subwoofer that you have chosen
   • Note: If your subwoofer has two RCA inputs, you will only need to plug into one (either red or white), not both. For more information, please see our article - Is a "Y" Splitter Needed to Hook Up My Subwoofer?

CAN I BUY ANOTHER CINEMA 400 SUBWOOFER AND USE THEM BOTH AT THE SAME TIME?

No, you cannot pair more than one wireless subwoofer directly to the Cinema 400. The wireless subwoofer that comes with the system is the only one that will natively pair with the sound bar over the built-in 2.4GHz connection. However, you can use a powered subwoofer that comes with a wireless transmitter that you can plug into the Sub Out on the back of the sound bar.

So, for instance, you could potentially achieve using two wireless subwoofers by using the sub that comes with the Cinema 400 system, and then using an additional subwoofer that comes with a wireless transmitter. Subwoofers like the R-10SWi, or the R-12SWi would be examples of a subwoofer that comes with a wireless transmitter. Plug the transmitter into the "SUB OUT" on the back of the sound bar and then pair the subwoofer to the transmitter using the instructions included with the subwoofer.
