I was a little skeptical about this product based on some of the reviews I've read online (e.g., thumpy sounds, negatively affected sound quality, etc.), I did not experience anything like this, although I do agree with some of the reviews that instructions on how to best set up the limiter were lacking. But fortunately, some of the previous reviewers provided their own tips, which I employed and that helped me with my setup. So I'd like to share my own tips based on my use case in hopes that they may help someone else.I am in a band that runs its own sound, and I use my iPod to play break music. While the songs on my iPod have the same general ballpark output level, some songs would still play louder than others, and I'd have to run back to the stage to adjust the fader on the sound board. This limiter solved that problem.I started by setting the playback channel fader on the sound board to unity (nominal position for playback).On the Rolls SL33b Limiter: (1) Initially set the Gain dial to the 12 o'clock position and the Threshold dial to the 9 o'clock position; (2) Adjusted the Gain dial on the limiter to set the volume desired in the house; (3) Adjusted the Threshold dial until the red Gain Reduction light would slightly flicker. Using this setup, when louder songs played, the red light flickered less and stayed solid red slightly longer, which meant the limited was engaging. Note however, that this setup did NOT peg the Gain Reduction light at a solid red when a loud song came on, which would have meant extreme limiting. I did not experience any thumping noises or altered sound quality because the limiting in my case was not severe. This was probably due, in part, to the fact that the output levels of the various songs on my iPod were not drastically different from one another.Bottom line: This worked well for my use case, and I am very happy with the purchase.

I'm craving this unit (for our TV), but I hesitate due to its lack of a bypass switch, to bypass the limiter for movies and shows with gentle soundtracks. Rolls -- Please perfect it by adding a bypass switch!

I use this for my TV. The sound travels from my TV headphone jack to this compressor/limiter then to an equalizer and then to a set of powered speakers. When watching programs, I would continually have my hand on the remote adjusting the volume to decrease the loud sections and boost the quiet sections. It just seemed like a lot of work. After plugging this in it is amazing how well it evens out the sound volume. Sometimes I will still make minor adjustments when commercials come on, but it is hardly necessary. I will always be using a limiter/compressor like this in the future. I don't like the wide swings in volume that occurs with a usual broadcast, so I set the threshold dial all the way to the left and then increased the makeup gain dial to a comfortable volume setting that works well as a baseline for my remote volume control. That's it! There is a green LED power button that is brighter than I would prefer, and a red LED indicator that never comes on. The unit is really set and forget. I do not hear any introduced distortion or noise. Perhaps I would if I was using a high output volume from the TV, I don't know, but it never degrades the audio signal for me. Obviously, this device only works when you are hooking up external speakers since it must be inline.

I have some cranky next-door neighbors. This thing gives me peace of mind when I'm watching an action movie or something where the audio levels jump all over the place. Makes dialogue easier to hear too.

The volume on social media videos is all over the place. One is soft and the next is super loud. This controls the maximum volume very well. You still need to turn softer vids up but then the next loud one doesn't blast out your speakers. Very happy with it.

I'm using this to level out the audio levels of different CD's in a jukebox. Most newer CD's tend to have higher audio levels than older released ones. This compresses the audio of the louder tracks. The drawback is loss of fidelity. But for a jukebox I can live with it.

I wanted it to limit the volume levels for streaming video. Does what it should do. Well-built as usual for this company.

If you use speakers for your tv sound (not the built in tv speakers) this device allows you to limit the volume that comes out of your speakers. This eliminates the problem of loud sounds, commercials or scenes when you are trying to watch a movie without disturbing your neighbors. The sound is a bit distorted when it hits the limit but this is to be expected. One note, the first one I got had a defective dial, but I easily returned/replaced it with a working unit. The instructions aren't great, the best way to use it in my opinion is to turn the volume of your speakers to very low, set the threshold to the minimum and the gain to the minimum as well, then slowly bring up the threshold till the red light flickers dimly when you are listening to a normal volume on your tv. If it's too quiet at that setting, and you don't want to/can't adjust your speakers more, bring the threshold up and slowly bring the gain up until the red light flickers dimly. Basically this gets the normal sound to be close to the threshold, and loud sounds will be dampened. Obviously you may need to play around with it yourself. One awesome feature is that it's a simple printed circuit board with easy access to the components, so if it ever breaks I imagine a repair would be easy enough.
