    Rolls PM55P reviews

    PM55P Stereo Personal Monitor Amplifier with Optical Limiter is rated 4.8 out of 5 by 9.
    Rated 5 out of 5 by from Affordable In-Ear Monitor with Limiter! Suddenly there's a safe wired in-ear monitor system for a fraction of the cost of other solutions! I called Rolls and they verified that the PM55P is a PM55 with the addition of a limiter to protect your ears from loud sounds like feedback. This is critical for replacing your boomy floor wedges with ear-buds, if you want to keep you hearing intact. It's built like a tank, has smooth dials and switches, and uses battery or an included AC adaptor. We place the PM55P on the floor instead of using the belt clip which is sort of useless. There's is a loud click when using the power button, so make sure your ear buds are out when switching on/off. The limiter works better than other's I've tried because it doesn't keep lowering the volume at every tiny louder input. Instead, this is at full volume until something seriously loud hits the unit. I think there's only one other manufacturer doing this at this price point. I picked this becuase it seems like the best all-around choice. Good Luck!

    Rated 5 out of 5 by from Just what I needed and very flexible. I am using this device so that the singer can monitor her voice through an ear bud which means she doesn't have to have monitor close to her mic. Also, she can adjust the volume to her liking. The mic can be passed directly through or it can accept a feed from the board or both at the same time. Very cost effective for the quality and usefulness. It can use batteries or a small power adapter. My only complaint is that it uses 9 volt batteries instead of AA's which are cheaper and last longer. But, I high quality 9 volt alkaline gives us about 6 hours of use.

    Rated 5 out of 5 by from Great addition for production audio The Rolls monitor is a perfect addition to my audio kit. I connect it to the output XLR of my boom and connect headphones. The audio loops through to another cable to the recorder. It allows a boom op (me) to monitor the boom audio directly without additional cables getting in the way on a tight set. It's powered by a 9V battery that seems to last the entire day. It attaches to the boom op via a belt clip. The only con is that it's a bit bulkier than I thought it would be.

    Rated 5 out of 5 by from A Keyboard Player's Dream! I play keyboards in a classic rock band and, up until now, I pretty much got buried in the audio mix. I decided to run the keyboards through the PA system with a monitor feed back to this Rolls unit and plug in my earbuds. It's got an onboard 9-volt battery, an optical limiter to protect my ears, and it's built like a tank. Great product, reasonably priced.

    Rated 5 out of 5 by from Great box! use as a talk back system or boom operation etc. I'm using this as a talk back headphone feed to my talent in a voice booth. I have a complicated multi-channel headphone mixer/amp that can give a whole band a custom mix, but there's no mic input. So I used to have a complicated setup just to have someone do a bit of narration or whatever. With this little box, you have a simple, functional setup where the talent and I can hear each other simply and without affecting the recording. The intended use is more likely to use this for actual program audio feed and monitor for a sound tech or boom operator. I'm sure it will work well for that and I intend to use it that way too. Nice to get multiple uses out of this box as compared to my previous devices that were so cumbersome to use, even for their intended purpose.

    Rated 5 out of 5 by from In Ear monitors on the cheap We purchased this to use with a Presonus Studiolive mixer.It will give anyone who doesnt need to move around on the stage the ability to use in-ear monitors. And with the Presonus app, they can adjust their own mix with their iphone. It is wired, but the battery power will let us connect with only one cord.
