TELEFUNKEN M60 FET Amplifier

Product overview

The TELEFUNKEN M60 FET Amplifier is the M60 FET microphone body on its own: the phantom-powered, true class-A discrete FET amplifier that accepts TELEFUNKEN's thread-on TK60, TK61 and TK62 capsules.

It is the part to buy when you already own TK6x capsules, want to add a second body to build a stereo pair, or need a spare amplifier for a busy studio or rental stock. Fit any TK6x capsule and it becomes an M60 (cardioid), M61 (omnidirectional) or M62 (hypercardioid). The amplifier is hand assembled in TELEFUNKEN's US facility using premium components and an ultra-clean circuit with an American-made transformer, and its circuit topology captures a wide frequency range for life-like reproduction of most sources.

Self‑noise (amplifier)	5 dBA
THD, amplifier, 1 kHz at 1 Pa	< 0.01%
Output impedance	120 ohms
Phantom power	+48V

Key features

• M60 FET amplifier body, supplied without a capsule
• Accepts all TK6x capsules: TK60 cardioid, TK61 omnidirectional, TK62 hypercardioid
• High-headroom, low-noise FET amplifier: true class-A discrete circuit
• TELEFUNKEN Elektroakustik T61CT American-made transformer
• Ultra-fast transient response and extended frequency range
• +48V phantom powered: no external power supply needed
• Designed and hand assembled in the USA

One body, three microphones

The M60 amplifier threads together with any TK6x capsule in seconds. Each capsule has an edge-terminated 15 mm diameter, 6-micron gold-sputtered membrane, is held to a strict ±1 dB sensitivity tolerance and is individually tested and matched by frequency response. With a TK60 the result is the M60 cardioid, ideal for drum overheads and acoustic guitar; with a TK61 the M61 omnidirectional; with a TK62 the M62 hypercardioid for cymbals, percussion and live stereo pairs.

Quiet and fast

With a capsule fitted, the complete microphone offers 20 Hz - 20 kHz ±3 dB, 10 mV/Pa sensitivity, more than 135 dB SPL handling and 89 dBA signal-to-noise ratio. The amplifier's own self-noise is 5 dBA and its distortion stays below 0.01% at 1 kHz and 1 Pa, so the body adds very little of its own to the capsule's sound.

Expand an existing system

Add the amplifier to a single M60 system to make a second microphone for stereo work, or keep one as a backup for touring and live sound. The slim 140 mm x 20 mm body is easy to place over a kit or close to an instrument. TELEFUNKEN's M 761 elastic shock mount, WS20 20 mm foam windscreen, ZC61 zipper case and SGMC-5R cable complete the microphone; they are not part of this amplifier-only product.

Setting up and care

TELEFUNKEN's quick start is simple: attach the M 761 shock mount to a stand, push the microphone through both sets of elastics, connect a 3-pin XLR cable such as TELEFUNKEN's SGMC-5R to the preamp input and apply +48V phantom power, allowing 15 seconds to power up. Mute the channel before engaging phantom power, as the microphone can produce a loud pop as it turns on. Phantom power is a standard feature of most mixers, consoles and preamplifiers, so no external power supply is needed on stage or in the studio. Between sessions, keep the microphones and capsules in the ZC61 zipper case (available separately).

Stereo configurations from the SDC manual

• XY (TK60 or TK62): two microphones angled 90 degrees apart with the centres of the capsules directly over each other, as close as possible without touching; direct-sounding and always phase coherent
• ORTF (TK60): two microphones angled 110 degrees apart with the capsules spaced 17 cm, designed to mimic the placement of the human ears
• Spaced pair (TK60 or TK61): two parallel microphones about 60 cm apart, or up to 3 m depending on the distance from the source, the environment and the desired stereo width
• Three-microphone tree (TK61 with SD40 spheres): left and right 2 m apart, centre 1.5 m in front, distances no less than 1.5 m

TELEFUNKEN M60 FET Amplifier: frequently asked questions

Does the amplifier include a capsule?

No. This is the M60 body only. Fit a TK60 cardioid, TK61 omnidirectional or TK62 hypercardioid capsule, or the TK6X three-capsule set, to use it.

Which capsules fit?

All TELEFUNKEN TK6x Series thread-on capsules: TK60, TK61 and TK62.

Can I build a stereo pair with it?

Yes. Add it to an existing M60 with a matching capsule; for factory-matched stereo, matched capsule pairs and complete stereo sets are also offered.

Does it need phantom power?

Yes, +48V phantom power. Allow 15 seconds for the microphone to power up.

Is a complete M60 FET available?

Yes, the TELEFUNKEN M60 FET (with TK60 cardioid capsule and accessories) is listed as a separate product at Shivansh Electronics.

Where can I buy the TELEFUNKEN M60 FET Amplifier in India?

The TELEFUNKEN M60 FET Amplifier is available from Shivansh Electronics, Kolkata, West Bengal, India, with delivery across India.

Workflow 1: Completing a microphone

Turning the amplifier into an M60, M61 or M62 with a TK6x capsule you own.

Connections

Connect	To
TK6x capsule	Threads onto the M60 amplifier
M60 (3‑pin XLR)	3‑pin XLR cable, such as the SGMC‑5R
Mic preamp	+48V phantom power switched on

Setup

1. Thread a TK60, TK61 or TK62 capsule onto the amplifier until it is seated.
2. Fit the microphone in an M 761 shock mount and connect a 3-pin XLR cable to the preamp.
3. Mute the channel, switch on +48V phantom power and allow 15 seconds for the microphone to power up.
4. Position the microphone for the source and set gain at full playing level.

Workflow 2: Building a stereo pair

Adding a second body to an existing M60 system for stereo recording.

Connections

Connect	To
2x M60 (3‑pin XLR)	Two 3‑pin XLR cables

Mic preamps	+48V phantom power on both channels

Setup

1. Thread the same capsule type onto the new amplifier and the existing M60.
2. Mount both microphones on a stereo bar and connect them to two preamp inputs.
3. Mute both channels, switch on +48V phantom power and allow 15 seconds for the microphones to power up.
4. Set XY (TK60 or TK62), ORTF (TK60) or a spaced pair (TK60 or TK61) and match gain.
