RE: MD: Loudness feature on stereos
I consider the loudness switch on an amplifier as simply a "preset" tone modification which provides a bit of extra low-end and high-end response to the signal, in addition to what was obtained with the tone controls. Actually, I think this has been stated, but a properly designed loudness feature would be dependent on the volume. At low volumes, the loudness feature should be on at 100%, but at higher volumes, the loudness would slowly be turned off, until the volume reaches a certain point where the loudness feature would turn off completely. Most decent units that have loudness I have seen operate this way, but cheaper units leave it on all the time regardless of the volume. I believe Sony's megabass operated this way, whether or not it still operates this way I'm not clear. - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]
RE: MD: Loudness feature on stereos
Hi everyone I consider the loudness switch on an amplifier as simply a "preset" tone modification which provides a bit of extra low-end and high-end response to the signal, in addition to what was obtained with the tone controls. The reason some of us run the function all of the time is because we still want to hear the bass notes and the higher treble when we play music at a civilised level most of the time, but occasionally run the system at a loud volume. Then we forget to cut out the loudness control. Also we often find that this "preset" gives a sound system a "rich sound" at all times, which comes in handy even with speech -- a feeling of you're there is brought across when the speech is given a bit of timbre.

Loudness controls on stereos can compensate for this." Which is it? My thoughts are that low levels on a stereo simply put through a low level of all frequencies, and the amp - providing it has sufficient headroom - will help the speakers produce these frequencies as best they can. The softness at certain frequencies would then come in with the inadequacies of our ears, which is partially corrected with the "loudness" feature. Thoughts? You are pretty much completely right. The loudness setting is designed for low volume levels but most people (like me) just keep it on the whole time simply because it sounds better. However, perhaps some speakers are not as sensitive to low/high frequencies at low volume levels as well. So at low volumes the ear hears even less low and high frequencies. (This is just a wild guess in my part, I'm sure there are some people with some real knowledge on this list who can give some input.)
