The Pearlman TM-47 cardioid tube condenser mic captures the sound, look and spirit of the classic U 47s from the 1950s. Built around a US-made capsule, BV8-style output transformer, paper-in-oil coupling capacitor and 6SJ7 or 6AC7 tube, the Pearlman TM-47 captures vocals and instruments with a nearly bottomless bass response, beautiful presence and an authoritative midrange that will raise the hairs on the back of your neck...in the good way.
