Episode 100 - In-line Mic Pre-amps - Chinese and Cheap!

If you have a Shure SM7B or similar dynamic, you'll know about the need for pre-amps, especially if you don't have the mic right in your face. I bought a couple of really cheap Chinese preamps, and discover all is not bad! This isn't a workshop accurate test - after all, if we wanted to measure the actual gain, then totally different methods would be needed. This is a real world test - and the noise being listened to is a mix of preamp noise from the recording device's preamp, plus the inline preamp, AND the room noise - which typically includes air-con, cooling fans in computers and even breathing. If we have a less than excellent preamp, in my case in a JVC camera, then any extra noise is a problem. All I have done is record each version, normalise it, and then see how far down from the maximum, the background noise - hiss, breathing, fans etc actually is. This is more a real world test - difficult on speakers unless you turn them up. much easier on headphones.
