The TELEFUNKEN TK60 is a small diaphragm cardioid capsule used with the ELA M 260 tube microphone and the M60 FET microphone. Featuring a 6-micron gold-sputtered membrane measuring 15mm in diameter, the TK60 has a surprisingly full low end for a small diaphragm capsule, and offers a quick and accurate transient response. These small diaphragm capsules are tested to a strict ±1dB sensitivity tolerance. The frequency response is flat from 150 Hz to 7 kHz, with a smooth, airy presence peak at 8 kHz making it ideal for drum overheads, acoustic guitar, and other acoustic instruments.
