I bought this for my son who uses his pc to game. He has one of the inexpensive Neweer condenser microphones that came with an arm and power supply from Amazon. The mic levels were always too low with just the power supply because it doesn't amplify. This supplies both the phantom power and perfectly amplified the microphone. And it's less expensive than the in-line amps while being good enough for gaming.

This works well for PC/Laptop microphone volume control.HOWEVER... You do need a lot of connectors because there is a dark little secret about most computer microphones most people do not know.If you ever looked at a computer microphone connector, you've probably realized that it has a 1/8th inch TRS connector. On headphones or speakers these 3 contacts are: Right-Channel / Left-Channel / Common-Ground.These 3 connectors are different on PC microphones and the microphones on headsets(headphones with a microphone attached). For these types of microphones the contacts are as follows: Microphone Signal / +5 volts / Common-Ground. You see, computer microphones need to be energized with around +5v to work properly. Otherwise the sound signal they produce is very VERY bad and weak.I bring this up because the Rolls MP13 amplifier here is designed for 1 channel microphones that DO NOT NEED TO BE ENERGIZED! This means if you just plug a computer micropone(or headset microphone) into the Rolls MP13 input and then connect the output directly to your sound card's Microphone Input: You will get a horrible array of loud random noises sent into your microphone line and it will seem like the Roll MP13 is broken.If you wish to use the Rolls MP13 as a computer microphone amplifier you need to split the Microphone signal and the +5 volt line.1) The +5 volt line must go directly from your soundcard to the +5 volt line on your microphone.2) The Microphone Signal line from your soundcard must be connected to the OUTPUT of the Rolls MP13 amplifier. The Microphone Signal connection from the MICROPHONE must be connected to the INPUT of the Rolls MP13 amplifier.If this is confusing to you, you should NOT try to use the Rolls MP13 on a computer microphone.

I’m using this between a dynamic mic and an inexpensive tripath amp and the sound is fine for voice use. Does exactly what I wanted it to and a lot cheaper and robust than a diy pre-amp project.

Bare minimum for a microphone preamp. The preamp is decent for use with electret or condenser microphones, however when it comes to dynamic microphones, the preamp has quite a bit of noise and you will want to use a noise gate or noise removal of some sort. The hiss will be faint but audible even in a very quiet room with a dynamic mic with average sensitivity.Rolls really needs to improve the design, with a little work it should be possible to produce a preamp with much lower noise, and I would easily pay twice the price for an inexpensive, American-made preamp that uses opamps and a servo-balanced output. I think an audio interface might be a better buy if you can find one, but due to the Honey Badger virus, it's hard to get your hands on one at an affordable price now days.

I use this to power a Neewer shotgun mic. It’s easy to use and boosts the signal precisely the way I want it to. I could not be happier. I’m also a big fan of stuff made in the US so this preamp fits that bill too. It’s truly great.

After using it for a short while the unit started to get intermittent. So I opened the box. What did I find? All of the leads on the PC board had not been cut and some were shorting to the case. I guess Rolls want their customers to do the QA. Well that is the last Rolls product I shall own. It looks like they do not really do any QA.

Returned. Gain switch did not work. Was either very low or very high gain; nothing in between. Supplier gets 5 stars; was very quick to address and issue a refund.

No issues at all. I feel bad for the people whose items came with electronics problems because I get a nice clear sound out of mine and it's exactly what I need for home recording.However, the jacks are not what I would call an ideal configuration. For output, you have an XLR and a 1/4 inch. For input, you have an XLR and an 1/8 inch. Why is the input not a 1/4 inch? I don't know. Since 1/8-/14 adapters are very common, I think it would be easier to have both jacks be 1/4 inch. But they're not. So just keep that in mind if you're buying with the intention of recording guitar tracks via direct input. Otherwise, great product.

Works well with no distortion or hum. Level control is smooth and quiet. Recommended.
