Sony Home Theatre system - speakers shut off?

BluEyedGrl

I have a sony home theatre. . when the volume hits a certian point (about 36) the speakers shut off and the display reads "protect" . . this is very annoying as it happens when the music is not particularly loud. . anyone know how to make it stop?

Answer
The system is protecting itself because your speakers are
presenting too much of a load on the amplifier. Either get
some 8 Ohm speakers or a better receiver than can han-
dle a tougher speaker load.

Logictech z623 2.1 speaker system high volume.?

Tyler

When I turn up my logictech z623 2.1 speaker system to %100 the subwoofer sounds different than when at %50. And it doesn't sound different in a good way. It seems a little sketchy and that it shouldn't be making that sound. Is it normal that its making a different kind of sound? Thanks in advance.

Answer
You can only turn up the volume so high before the amplifiers for the sub and speakers run out of clean power and start to clip (distort). Turning up the volume past the point where you start to hear distortion causes the amps and your speaker coils to heat rapidly and will eventually damage your speakers or amps.

The volume control is made so you can still get good output, even if the input from your source is a bit low. With a strong source, you should not expect to be able to turn the volume all the way up on any audio equipment without causing clipping. That's almost never the case.

Connecting and External Powered Speaker to TV with Optical Output Cable?

system speaker volume image

Mark

I have a brand new Samsung 32" HDTV and it has an optical audio output that I would like to connect to a external speaker system. It is a tower speaker, self amplified sold at Brookstone (Big Blue Media Tower) and it has a optical input. I know it will work as that is how Brookstone advertises it for a TV, kind of like a sound bar. My question is that Samsung says I have to control the speaker volume with the speaker remote and others online say if I set my TV menu to external speaker, the external speaker volume can be controlled via the TV remote, please clarify if you know the answer before I buy this system, thank you for your help.

Answer
To control the speaker volume you have to use the speaker remote.

What does -10 mean for home system speakers?

Anna

When I watched an action movie, there was an explosion in the movie and the sounds from the speakers had big boom. It was really loud, and it shocked me. If I turned the speakers volume to -10, will that make the sound softer?

Answer
Then calibrating each individual speaker on a surround sound system, each speaker has an adjustable range from -10 to +10. The default setting for all of the speakers is at 0. This adjustment is used to fine tune the SPL (sound pressure level = volume) of each individual speaker in representation to the viewing location. Idealy, you would want all speakers to be the same distance from the viewing location, but since they is rarely possible, this adjustment is there to compensate.

As for the issue you are having. This has nothing to do with speaker calibration, but compression. When a theatrical movie is broadcast over our TVs, the sound is compressed. This means that the range between the loudest sounds and the most quiet sounds is reduced. The higher the compression, the more flat the volume response is. Networks do this in order to prevent people from blowing out their TV speakers.

As for DVDs and Bly-Rays, the compression is set very low, so that the viewer can get that theater feel. Low compression means that there will be a bigger difference between quiet sounds and the explosions. This is how the movie is intended to be watched. Pay attention the next time you're in a movie theater watching an action movie with explosions.

The loud explosions doesn't mean that your surround sound isn't set up correctly, but that it IS working properly. That's why it's called a home theater. It is supposed to mimic the sound of a real theater, and that means loud explosions.

If these loud explosions are a problem for you, then perhaps your surround sound receiver has compressions. Many of them do these days. Sometimes it is known as a "late night" feature. This will tone down the explosions and amplify the whispers allowing you to listen to your movies as a lower volume.

Adjusting each individual speaker volume isn't the answer. This will only give you unbalanced audio.
