The first unit received had a bad audio channel that failed when the volume went above 30. After contacting the vendor, a replacement arrived within 2 to 3 days and it works as expected. A responsive vendor is rare in these days of 'greed is more important than life itself' (think climate change). I would have given 5 stars but the original unit arrived DOA.This does a resonable job of suppressing the loud advertisements and boosted audience applause found on most TV shows and movies.Good job from this vendor.

A bit touchy when dialing in but nice.

Am using it with a bluetooth transmitter headset to listen to television w/o bothering others. Properly set, the program material is at a comfortable level and the commercials (albeit clipped and distorted but, who cares?) don't 'loosen my teeth'.

I was looking for a way to turn up Ps5s volume in Modern warfare 2 to hear footsteps better, however if you do that the act of shooting your gun is so loud and grenades and flashbangs are so insanely loud it's physically painful, and obviously bad for your ears. With this little guy I can turn the volume way up, and filter down all the excessive noise from gunshots and explosions.Honestly, this is kind of cheating if I'm to be honest. I can hear way more than other people bc footstep audio isn't loud enough to trigger the limiter, so I can get the volume up really really high to where normally footsteps would be nearly inaudible for everyone else, but crazy loud for me. Not to mention before the limiter, the audio is being pushed through a bellari EQ so I can adjust frequencies as well(ie turn down that ear piercing head shot tinnitus sound).I'd give it a full 5 if it weren't for me having to turn on my phones flash light to see where the threshold is at when I'm adjusting it so I can note it's position for later. Also the threshold knob arrow thing is full black, I'll have to put whiteout or pain in the little indicator thing to see it easier. Also you have to guesstimate where exactly the knob is positions since there are no hash marks around the knobs.But for what $80-90 bucks, it's the only thing I could find that didn't jump into the 150-1000 range, and those turn into compressor/limiters. I just wanted something to quiet down the explosions and gun shots.... This works perfectly.Also... I now have bought 3 rolls products back to back to back, the mixer, belarri eq and now this limiter.Can I tell you how awesome it is/was to not have had to go with different manufacturers. One stop shop.

Look Mom can't explain things well, but she hasn't complained about this one like the last one. nuff said.

Really glad I found this. For years I've been tired of the sound on movies and commercials just suddenly blasting. I'm sure my neighbors below me feel the same way. This device essentially reduces or limits how extreme those loud moments get. It goes between the RCA or 1/8 stereo output of the TV and and the RCA or 1/8 audio input of your external home stereo amplifier. (Cables not included.)Unfortunately, the instructions don't give a lot of detail about how to get a good setting. If you set it too high, the loud moments will distort and if set too low it won't affect the audio very much. I recommend setting your TV at about 80 maximum output and set your amplifier low at first. Play a part of a program that is particularly loud. Set the threshold really low. (This controls at what volume the limiting effect is triggered. The lower the threshold, the more it limits.) Use the make up gain control to bring the normal sound level back up. You should see the red light flashing when the effect is working on louder moments of sound. When the threshold is low and the make up gain is high, the light will flash a lot or stay lit which probably means the sound is distorting. Experiment and adjust. When it sounds right to your ears, then set the level on your home theater amplifier to your liking.

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!

as described. limits by attack threshold with gain, 2 channels (RL), 3.5mmRCA jack in/out. 15v 500mahI love it

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.

Nothing!

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.

Nicely made. Auto levels my stereo for streaming background audio while I work.

I have always preferred to use an equalizer with my home system. Modern receivers, however, are not equipped to use one. I am streaming hi res audio from My Roku using an external HDMI to analog converter, then to my equalizer and then to the receiver's AUX input.Without the limiter, the input volume was very high, peaking at 6db according to my EQ's spectrum analyzer.The limiter allowed me to turn the input volume (voltage) down to where only a few frequencies peak above 0db infrequently. This has taken care of an annoying boom in bass at around 60hz that I had before this.I have noticed that the audio compression portion has to be set somewhere near the same as the limiter or there is a good chance for distortion. But, it works very well being set similarly.For the price, I am very pleased.

Here's a tip: Keep the two knobs as mirror images of each other. For example, if the left knob is at the 2:00 position, put the right knob at the 10:00 position.This device works exactly as intended. When the TV's background music would otherwise get too loud, this device limits it.There's one thing that's a bit surprising at first, but you get used to it: The volume levelling works in both directions. So, the soft click sound you hear when you (e.g.) make channel selections on your TV are now amplified. Again, not a big deal, just something to get used to.

After a little tweaking the loud stuff wasn't so loud and the soft stuff wasn't so softAwesome
