www.audiomasterclass.com - This video shows extracts from a test we made at Abbey Road Studio 2, where we compared two microphone preamplifiers on female vocal. Tested are the Universal Audio Solo/610, which is a vacuum tube preamp, and the Focusrite ISA One, which uses transistors.
Both preamps feature gain and output controls. In theory, using a high gain and low output should give more warmth; low gain and high output should offer a cleaner sound. Listen to the results and decide for yourself...
Addendum: We repeated this test with three microphones - AEA A440, sE Electronics 4400a, and Violet Flamingo. When we get a moment we'll delve into the archives and find out which one was used for this test. In the meantime, any guesses?
UPDATE: We have checked this against our original video footage. The microphone is the sE Electronics 4400a set to cardioid pattern.
