Telefunken TF11 – FET condenser mic
Blending an Austrian-inspired voicing similar to the legendary C12 with modern FET high performance, the phantom-powered TF11 exhibits a beautifully open and detailed frequency response with exceptionally fast transient response, high SPL handling, and low self-noise. The compact, cardioid only TF11 is versatile, portable, and dependable for all recording environments from home to studio to stage.
Circuit Design
The TF11 features a unique combination of circuit elements shared with other TELEFUNKEN Elektroakustik designs. The CK12-style edge terminated capsule is a single membrane version of the capsule featured in the TF51. The amplifier is a unique proprietary take on the classic FET microphone amplifier similar to the M60, coupled with a custom large format nickel-iron core transformer made in the UK by OEP/Carnhill. Premium through-hole components include UK-made polystyrene film capacitors, Nichicon Fine Gold electrolytic capacitors, and a high-performance, ultra-low-noise JFET amplifier.
