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.

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

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.
