Using a Peak Limiter as protection against bursts

I am a novice and would love some insight from an expert (or experts).
I am just sick of having to turn my volume up to hear what is being
said in a movie and then blasted out of my seat seconds later by a car
crash or a tidal wave or whatever.

My system: VCR, DVD, and TV audio ouput goes to a consumer amp and
then on to two pretty good speakers.

I bought a Peak Limiter on ebay. It is an Alesis 3630 compressor
(dual channel compressor limiter with gate). I'm pretty sure I can
make a cable than connects the RCA plugs from my DVD system to the 1/4
inch plugs of my Peak Limiter, and then another one to connect back to
the amp. But, that leaves me with VCR movies still being a problem.

Certainly, I can insert another component (a reciever) into this and
have the DVD, VCR and TV go into that reciever, and then have that go
into the Peak Limiter, and on to the amp and finally to the speakers -
which I would like to call plan B.

My question is, would it work - without damaging the amp or the
speakers in any way - to just insert the Peak Limiter between the amp
and the speakers? I have never heard of anyone doing this.

Lastly, there is a port on each channel in this Compressor called
"Side Chain, Tip = return, Ring =send". For my intented purposes, it
is okay for me to never know or care what this is for? Otherwise,
could someone help me understand what I need to do about this?

My guess is you do not need a limiter at all, but rather to tame the
acoustics in your listening room. Lack of intelligibility is a huge problem
in most rooms - once you fix that you'll be able to hear the dialog and
understand the words at normal (lower) volume levels.

Okay well thanks, but now that I have one and my interest is piqued,
any ideas on the electronic approach?

The Alesis 3630 is a well known POS, among compressors.

That's because its a horrifically bad idea as stated. The output of the
limiter is no way capable of being hooked directly to speakers. You'd need
another power amp for that. Then you'd need something that would convert the
speaker outputs of your existing receiver to line level for the input of the
compressor. You can find those among car audio accessories.

Right now, it's a "don't care". It's a refinement that you don't need to
worry about until you are experienced with the basic implementation.

Start out with plan B and see whether compression meets your basic needs.

Rob,

The best I can offer is my brief compressor tutorial, 8th in the list on my

Thanks for helping me out! Plan B is now plan A. I wish I could see
a diagram with a short sample waveform starting at the first
component, and seeing how it is changed after each component. That
would be really helpful for me to understand this stuff better. Just
curious, would the putting the peak limiter between the DVD and the
amp work? (obviously not for the VCR and TV!)

Need more info on system. If its possible to get at a stereo signal, then many devices could
be hooked up to it. If its a multichannel decoder, then it might be very difficult.
