This ad is for a single (1) Audio-Technica AT-4060 'vacuum tube capacitor studio microphone. Purchased new in the early 2000's, (so only 1 owner), used in non-smoking in-studio or on-set uses only. In really nice condition ...(some rack/scuff marks on the power supplies ...that's it.)

From the SoundOnSound review of the AT-4060 microphone
"...the 4060 utilises a brand‑new, externally polarised, large‑diameter capsule. As with all the Audio Technica mics I've tried in the past, they've clearly paid a lot of attention both to engineering detail and to sound quality. Though it offers only a fixed cardioid pattern, the capsule has a dual‑diaphragm construction, ostensibly to improve the high SPL capacity of the mic without compromising its high‑frequency performance...
...the AT4060 employs gold‑coated diaphragms fabricated by a vapour‑depositing technique. The capsule is then artificially aged using a five‑stage process to give maximum stability over its operating life...
..it can handle levels of up to 150dB without either the capsule or the preamp contributing significant levels of distortion...
...the AT4060 comes over as a very nicely engineered microphone with a more than respectable paper specification, but what really matters is the subjective sound. In comparison with the 4033, the 4060 is similar in character but a little richer‑sounding in the lower‑mid and bass regions. The top end is both smooth and detailed as well as being very open‑sounding. It doesn't scream 'valve mic' at you right away, but that's no bad thing, as too much artificially created warmth can often make the sound seem a little congested. The performance is more like that of a pedigree valve mic — it flatters the sound, but not in an over‑obvious way. Vocals sound solid, natural and airy, while plucked stringed instruments come over with plenty of dynamics and life...the AT4060 delivers a very classy sound...the 4060 is a nice‑sounding, beautifully made all‑rounder...
...I also appreciate the honest valve sound, rather having overblown distortion thrust upon me as a feature I can't turn off! The AT4060 is most definitely a worthwhile addition...
Summary - A tube mic that performs with class rather than flaunting an over‑emphasised tonality.

The mic comes with its matching serial number power supply, a removable IEC power cable for the power supply, a shock-proof mic clip and a 10 meter 6-pin 'mic cable' ...that connects each mic to its power supply ...(you then use a standard 3-pin XLR cable to to connect the power supply to your mixing desk, preamp or audio interface).

The little video shows two 4060's (because I originally had a pair of them - BUT ONE OF THEM SOLD ALREADY) ...the video shows both of the mics working. You can see the the mixer-channel input meters responding to each mic ...more importantly, you can see each mic's output signal on the larger 'selected channel' meter in the center controls of the mixer. The video starts with mic 1/ch 1 selected ...and a little later, I manually select mic 2/ch 2.

(This ad is for 'mic 1' of the original pair I had.)

The larger meter gives a better sense of how each mic and its channel are responding to 'quiet', then 'louder' sound-sources. There is a wee bit of air handling noise ...(and maybe our cat) way in the background.

Obviously ...this is not intended to pass as a 'sound-quality' test ...it's just to confirm that:
- all is well with the mic I'm selling
- it's working quietly
- it's ready for their next chapter of music making and audio creativity.

The current price of a new AT4060 tube mic is $2450 + tax (!)
