Customer Reviews for Microphone Preamplifier

Sort by:

Excellent device. Sole problem is if used with a single balanced mike and balanced-to-phono adaptor, the adaptor is a bit bulky and the nearest RCA output plug shoves it over a bit. It still works. Otherwise brilliant with no mains hum and a good line level. I use it for vocal pianobar boosting the signal to use the BOSE mini computer sound system as the output. The amplified voice filled Harrods computer section with ease!

The preamplifier works well but unfortunately the switch-mode power supply currently being supplied with it is very noisy. Substituting a liner power supply module cured the problem.

I have done a few discos for the community near where I live, and I use a laptop with my cd collection converted to mp3's with the sound output going through a pro-sound 1000 amp to two pro-sound speakers. I had a pro-sound microphone that I wanted to use for the discos but the line-in on the laptop wouldn't accept the microphone levels. I purchased the pre-amplifier to see if that would help, and it worked on it's own as input to the amplifier, but trying to use it through the laptop was still not working. Still, either way, the discos were a huge success and I will be continuing with them when I am next asked.

The product was bought to enable me to feed a top quality microphone into the line input of my computer. It is far too hissy - even with shorted jacks in the inputs.
