The cardioid-only TF11 is versatile and dependable for all pro audio environments, studio or stage.

The company’s first large-diaphragm, phantom-powered condenser microphone, the TF11 blends an Austrian-inspired voicing similar to the legendary C12 with modern FET performance, for an open and detailed 3D sonic image, with quick, accurate transient response, high SPL handling and low self-noise.

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 mic amplifier similar to the M60, coupled with a custom large format nickel-iron core transformer by OEP/Carnhill made in the UK. Premium through-hole components include UK-made polystyrene film capacitors, Nichicon Fine Gold electrolytic capacitors, and a high-performance, ultra-low-noise JFET amplifier.

Applications include vocals, strings, acoustic instruments, guitar cabinets, horns, piano, drum overheads, upright bass, woodwinds, percussion, etc. Available as single mics or matched stereo sets, the TF11 was developed to bring the Alchemy Series pristine audio quality into a more compact and convenient package, designed for the studio, built for the stage, and affordably priced. Created, hand-assembled and tested in the USA, all critical components are subject to the same high standards as the rest of TELEFUNKEN Elektroakustik’s product line. Retail is $895.
