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.
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.
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.
