Audio professionals looking for that classic Neve sound will appreciate the Kahayan 12K72, a dual-channel microphone preamplifier that's inspired by the Neve 1272 mic preamp.

The unit provides two mic/line preamps working in pure Class-A topology. Discrete components (no IC) are used throughout including Carnhill Transformers. The 12K72 offers a clear and transparent sound with deep bass and natural treble.

• Mic/line independent preamps working in pure Class A
• Using discrete technology (without IC's) with Carnhill Transformers
• Gain control in steps of 5 dB
• Output level control in steps of 1 dB
• Phantom power 48V with pilot light
• Phase reverse switch
• Microphone/line switch (also useful in line mode for mastering or mixbus processor)
• Inputs and outputs: balanced and unbalanced (XLR and jack)
• External high-quality power supply
• Front input jack for connecting high impedance electric instruments (guitar, bass, synth, etc.)

• The 12K72 is formed by two stages. The first gain stage is set with a Gain control, while the second stage remains fixed.
• The Output control regulates the amount of signal passing from the first stage to the second stage (as a typical fader function).

Related Questions and Answers

Q: 1. Does this mic give the left ear to one mic and the right ear to the other or does it do a mixdown into one mono channel?

A: Based on the description, this unit will output both sources to a mono input. This would suggest that both sources will be mixed together going into any device.

Q: 2. Will the Sony ECM-44B - Omnidirectional Lavalier Microphone work with the FetHead Phantom?

A: Sorry, I just don't know.

Q: 3. Does it work with iPad?

A: Iphones and Android input mono via their TRRS (headphone) jacks. Both mikes will record onto 1 channel. The Rode SC6-L will input a true stereo input into an IOS device through it's lightning connector. This Polsen OLM-20 will input into an Ipad 1 channel mixing both microphones.

Q: 4. Hello,According to Sure all of their dynamic microphones are unaffected and will not cause damage or cause poor performance if phantom power is used. Also other sources state if a dynamic mic is newer and or balanced it can be used with phantom power. I have both dynamic (Sure) and condenser mics. Will a dynamic mic damage the Fethead Phantom or will it cause poor audio performance while used with dynamic mics? Thank you and have a great day,McCoy

A: As you know the Fethead Phantom passes phantom power through to the microphone after it uses a portion of it for its own operation. I oubt that a dynamic microphone will damage the Fethead Phantom. However, the impedance of the Fethead Phantom I believe is different than the standard Fethead as it was designed for low impedance condenser mics. The regular Fethead has an impedance of 22K ohm whereas the Phantom version is lower (I believe around 1K). So if you are using a high impedance dynamic mic with the Fethead Phantom the audio performance may be affected. However, a competitor of the Fethead, the Cloudlifter is around 3K, considerably lower than the regular Fethead. I purchased the Phantom version for use with condenser mic and have a different product for my dynamic mics. But I would not be concerned to try Fethead Phantom with my dynamic mics. One issue I had with the Phantom (a few others have reported it as well) is that with one of my condenser mics (none of the others) it was picking up signals from a local radio station. I spent a considerable amount of time trying to discover why this was happening as normally that was not an issue with that mic. I ended up adding a Sescom inline RF filter (SES-Inline-EMCM) at the end of the XLR cable before it goes into the mixer. This worked very well and eliminated all the RF signal. And in fact I found I could attach the Fethead Phantom to the Sescom adapter without any issues. Normally Triton recommends that the Fethead is attached directly to the mic connector. I hope the above helps.

Q: 5. The rode NTG-2 has can power itself with a AA battery. Will that battery power transfer also the this Fethead or must the Fethead power come from the recorder? I would like to plug NTG-2/Fethead combo directly into mirrorless camera.

A: No, the battery power for the NTG-2 will not also power the TRITON AUDIO FetHead Phantom In-Line Microphone Preamp.

Q: 6. Can I plug in a thumb drive to this unit and record vinyl directly on to the thumb drive? I ask so that I can use the the drive drive in my auto to listen to vinyl lps.

A: No

Q: 7. can this unit only be powered by the internal battery?

A: The Saramonic SR-PAX1 Two-Channel Audio Mixer, Preamp, Microphone Adapter is powered by a 9V battery. It does not have an internal rechargeable battery.

Q: 8. Is this the correct Fethead for the Deity S-Mic 2S? Or should I be getting the regular Fethead? (The S-Mic 2S is a phantom powered mic, but even still this isn't clear).

A: This is the correct model.

Q: 9. I'd like to connect these to a xlr snake that goes to an audio mixer. What adapter would i need?

A: All you will need in order to connect it to your snake is a 3.5mm female to XLR male see one option in the link bellow https://www.bhphotovideo.com/c/product/387850-REG/Rode_VXLR_VXLR_Mono_Mini_Jack.html?sts=pi&pim=Y

Q: 10. How long does one battery last?

A: The battery life is not specified. However, users say they get about 40 hours. I've had this mic set for over a year with a spare battery. It is still running on the original cell. It goes on, and on and on. Keep a couple of spares and don't worry about it. It's not a problem,
