Get more from your sound bar by using your TV as a switcher
Your sound bar may only have a couple of inputs, but you can easily expand its connectivity by using your TV to switch among devices.
Many sound bars offer only a small number of inputs, with often just a single digital and analog audio input on the back to handle your gear. That's hardly enough for a modern home theater packed with a DVR, game console, Blu-ray player, and streaming-media box.
Luckily, you can get around your sound bar's limited selection of inputs by using your TV as a switcher. You'll be able to connect as many devices as your TV supports, and it will even simplify the input selection process.
Here's how to do it:
1. Connect your home theater devices to your TV
First you'll want to connect all your home theater devices (DVR, game console, and so on) directly to your TV. In most cases, this means simply connecting an HDMI cable from your TV to one of your TV's HDMI inputs. If you have devices that only support analog video (looking at you,
2. Connect your TV's audio output to your sound bar
If you look look at the back of your TV, you'll likely see either a digital and analog audio output, although some TVs have both. (If you don't have an audio output on your TV, this method won't work for you.) You'll want to connect your TV's audio output to one of the inputs on your sound bar. The digital audio output is best if both your TV and sound bar support it, but the analog audio output will work too.
Once you've made this connection, the TV will output the audio from whichever input you've selected. So if you've connected your cable box to HDMI 1 and selected that input, the TV will output the cable box's audio from the TV's audio output. What's nice is there's never any need to change the input on the sound bar, since it's all coming in through a single connection. That means less fumbling for additional remotes.
3. Disable your TV's internal speakers
If you made all the connections properly, you should be hearing sound from your sound bar, but you may be getting sound from both your TV and sound bar. That generally doesn't sound good, so you'll want to disable your TV's internal speaker. The exact process will differ depending on the type of TV you have, so you may need to consult the manual. On our main home-theater testing TV, we needed to select Sound, then Speaker Select, then choose External Speaker.
One quick note of caution: if your sound bar didn't come with a remote, you may run into an annoying problem in which your TV will display an onscreen error message when you adjust the sound bar's volume. Read myfor more information.
What's the catch?While this method of connecting your home theater gear will work in most instances, there are some scenarios in which you might have issues. One problem is that TVs typically don't have audio-only inputs for devices like a that you might also want to connect to your sound bar. You can get around this by using the analog audio inputs from an analog AV input, but you're out of luck if you want to use a digital audio connection.
Another instance where you might run into trouble is if your TV doesn't have enough inputs to handle all your devices. You can get around this by connecting some of your device's audio outputs directly to the sound bar and running others directly to the TV, although this makes switching between your components considerably more confusing. (A good universal remote can make it easier, though.) Another option is purchasing an HDMI switcher to add more inputs. It's a cheap fix, but it will add more clutter to your setup and, again, make switching inputs a little more confusing.
Finally, there's the issue that most TVs downgrade incoming audio to stereo, rather than preserving a true surround-sound signal. It's not a big issue on most sound bars, which don't sound any better with a true surround-sound signal, but some sound bars, such as the such as theand , do benefit from a full 5.1 signal. We've and found that Sony, Toshiba and Vizio models pass 5.1 signals properly, but the rest of them don't. If you have a TV that "dumbs down" surround sound audio and a sound bar that benefits from a 5.1 signal, you'll have to choose between the simplicity of connecting devices to your TV vs. the superior performance of connecting devices directly.
