Expert Answer

Put more soft, plush objects in your room to help absorb the sound and make it less echoey.

Question

What if my sound system sound track is slightly off from the TV?

Justin Shaffer

Community Answer

If you're using an A/V receiver as your source, go into the setup menu and check if there is a A/V -sync setting. If so, adjust the ms level up or down to match the sound of the screen. It's best to watch a person talking on the TV, and then set the A/V-sync level to the proper level to where the audio lines up to their talking.

Question

Why does the audio stay on when the TV is off?

Community Answer

If you're using a receiver and the source of the sound is coming from something other than the TV (for example, a cable box, DVD/BlueRay player, etc.) and they are connected directly to the receiver, then the audio will continue to play even if the TV is off. This will continue until you shut off the source or until you shut off the receiver.

Question

Where do the ceiling speakers connect on the back of the receiver?

Justin Shaffer

Community Answer

On a 9 channel receiver, they should connect to the only speaker connections left after the Front L+R - Surround L+R - Center - Surround Back L+R.

Question

How do I connect if the sound system has a SCART socket and no HDMI, but the TV has no SCART socket, only HDMI?

You would need to purchase a SCART to HDMI adapter in order to connect it. You can purchase them online.

Question

Is a home theater sound bar as good as a receiver and multiple speakers?

Justin Shaffer

Community Answer

The theater sound bars sound great. But it can also depend on the size of the room and your own personal tastes.

Question

Where does the audio plug from subwoofer go into the TV?

Justin Shaffer

Community Answer

You can't unless you have a set of speakers to go with it. You would need a sub with a built in amp. Also the sub would need to have a speaker output that can run to a set of speakers or a sound bar with a built in amp that have an input the same as the output as the sub. From there you would need to use the L+R analog out put from the TV. Take an analog L+R cable and run it to a Y- 2 to 1-adapter and then to the sub. If the sub doesn't run to an additional set of speakers, the second you connect it to the TV, it cuts out the audio and all you'll hear is the base.

Question

Can my center speaker connect to digital audio out of the TV, while the others (7.1) connect to the A/V receiver?

Justin Shaffer

Community Answer

No. Whichever audio output is operating at the time will cut the audio output on the other. You can't have two audio outputs running at the same time.

Question

How do I hook 7.1 analog cables from a Blu ray player to my receiver/amp?

Justin Shaffer

Community Answer

If you want the full 7.1 sound performing on the receiver, the receiver would need to have a device selection with a 7.1 analog input.
