i wanted something easy to use when making mix cds for the car, using my old sony 5 disc carousel changer to my teac cd recorder to keep from going into the "red" . i also use an stereo eq also in this process. the unit does come with a 12 volt power supply (not mentioned in the product specs, but no rca cords). in my case i set the gain at straight up 12 o'clock & the threshold full tilt clock wise and get great results. also works great for making cassettes. by the way it also has 1/8" stereo in/out too. this unit replaced my old broke down humming alesis nanopressor . me thinx this unit could also be used in a home entertainment system such as if you have dish/directv to smooth out the volume in movies, sonic tap audio channels etc. pardon my spelling
but i'm just just trying to help.

p.s this should be found in electronics, not just musical instuments

This is one of the best purchases I have made in a while. I listen to a lot of music and movies in my room and it's easy to disturb other members of the household at night. I could be listening to music and one track might be almost twice as loud as the previous or I'd be watching a movie and everything would be perfect until the action scene with all the gunshots and blazing explosions booming. Also great for limiting the loudness of those annoying commercials that come on in between your show. With this, no need to constantly have my hand monitoring the volume knob of the device for which I am using. The rolls limiter keeps everything just right.

I am surprised there are not more companies out there making simple consumer level units like this. At the same, time I am sure that the majority of people out there would have a hard time grasping the concept of this device and how it works.

Settings: I turn the makeup gain to about 1-2 o'clock and the threshold to about 9 position. Turn volume up all the way on the device (iPad, projector, laptop). Set volume on external speakers to comfortable level and done.

Unit is about 3.5" x 1.5". Very small so you can tuck it away just about anywhere.

Works perfectly once I figured it out.
I work in a busy dental clinic with a moderate constant background noise of instruments and chatter. Radio stations are usually well modulated for volume control but CDs and downloaded music are not, especially classical and movie music. But I want to play MY music at the clinic, not a radio station.
So I made a playlist of music I like that should be un-offensive to most people 18-80 years old--not an easy task without resorting to elevator music. I loaded the playlist onto an old iPod and play it through an Altec Lansing $80 speaker system (no longer available but my Bose Companion 3 is equivalent in quality but costs a lot more). At first it was impossible to keep the volume at a level that was usable: it was always too loud or too soft with unpleasant way-too-loud occasional outbursts. But turning the volume low enough to prevent the volume outbursts meant missing most of the lower volume parts.
This item was the great solution. It brings up the lower volume parts and lowers the high volume parts to a pleasant smooth more constant volume level.
But there are some tricks I had to learn:
1. I must plug the iPod into the input jacks of the Rolls unit and set the volume control on the iPod to maximum level. If the iPod is set to less than its maximum volume then the Rolls does not do its magic.
2. I must set the THRESHOLD control at its lowest level (-13dB).
3. I use the MAKEUP GAIN control as my master volume control. Works perfectly just like a volume control on any device.
4. Set the speaker system volume control at a level that is the maximum you would want it to be and still be comfortable. The MAKEUP GAIN control will be adjusting the volume when you want it softer or louder.

Very good compressor that I imagine can be used for line in recording on your computer or with a USB audio interface. I tested it with an audio signal as low as 60 milli Volts; Compression starts at makeup gain = 1/2 giving an output of 130 milli Volts with threshold at 1/2 or maximum. With imput of 130 milli Volts, you can't set makeup gain to maximum otherwise there will be noise (anyhow the output will be too high to use). Compression starts with makeup gain = 1/2 output is 250 milli Volts with threshold at maximum. I tried 500 milli Volts input with makeup gain = 1/2 and threshold at maximum and the output was good. You normally don't have to have an input this high, it would overload recording input. I think normal recording input is 120 milli Volts for Wavosaur or Audacity or a cassette recorder. I would highly recommend this product the Rolls SL 33B.

Nice little unit, dedicated to one purpose only: to keep the audio signal from being too loud. Seems to work as promised.

I used it for my guitar on the 2nd night of a 2-night restaurant gig, because on the 1st night I was told the sound was too loud sometimes. Running through the limiter, I got no complaints.

The 3 major downsides to the unit are:
1) connectors are 1/8 inch jacks and RCA. Would've been great if the 1/8 inch jacks were 1/4 inch instead - but the unit is supposed to be used mainly for consumer stereo.
2) No LED decibel meter. It's really handy to have a visual reference. Of course, the unit is designed to prevent overloading...
3) the output gain control was dirty sounding when turning the dial, but didn't affect the signal when not being turned

I'd give it a 5/5 if these issues did not exist. Overall, a useful little unit when you need it.
