Tested to a sensitivity tolerance of 1 dB, the Telefunken TK60-S is a matched pair of small-diaphragm capsules made to fit ELA M 260 or M60 FET microphones. These 15mm diameter condenser capsules feature gold-sputtered membranes and cardioid polar patterns. With a flat response from 150 Hz to 7 kHz and a smooth presence peak at 8 kHz, they are well suited for drum overheads, acoustic guitar, and other instruments.
