How we ranked these mic preamps
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.
- Max gain weight 2
- 48V phantom power weight 1
Buying advice: condenser microphone preamp
Decide what the preamp must do
Preamp jobs differ across this list. The EAJONC adds 3-band EQ and gain before a mixer, the Xvive supplies phantom power from a rechargeable battery, and the Shure and MXL microphones carry their own preamps. Match the job to your setup, since a phantom supply and an EQ preamp solve different problems.
Check phantom power before you buy
All five picks involve 48V phantom power. The EAJONC and the Xvive supply it, while the Shure microphones and the MXL microphone use it to run. Check if your mixer already supplies phantom power, since a supply in the chain changes what you need.
Check weight and warranty before buying
Weight and warranty differ across this list. The Xvive weighs 0.3 lb and is the Lightest Pick here, the SM35 weighs 0.4 lb, and the BETA weighs 2 lb. The EAJONC and the MXL carry a 1 year warranty, and the SM35 carries a 2-year limited warranty.
Frequently asked questions
Do condenser microphones need phantom power?
Yes, condenser microphones need phantom power to run. The Shure microphones and the MXL microphone in this list use 48V phantom power, and the EAJONC and the Xvive supply it.
What does a mic preamp do?
A mic preamp raises the microphone signal before it reaches a mixer or recorder. The EAJONC adds gain and 3-band EQ, while the inline and built-in preamps in the Shure and MXL microphones raise the signal inside the mic chain.
Can a phantom supply run on battery power?
Yes. The Xvive runs on an internal rechargeable battery for up to 40 hours and switches between 12V and 48V operation. It connects in line between a microphone and a mixer.
What is a half-cardioid polar pattern?
A half-cardioid pattern picks up sound mainly from one side of the microphone. The Shure BETA 91A uses a half-cardioid pattern for kick drum use, where rejection of sound from other directions matters.
