Description

Advanced Audio CM47

The Advanced Audio CM47 is a large dual-diaphragm, multi-pattern, tube condenser microphone inspired by the famous U47. The CM47 is a great choice for vocals, saxophones, acoustic instruments, and excels in front of bass and guitar amps.

Maria Bobone featured using the AA CM47 on her beautiful vocal. You can also hear the CM54 being used on Portuguese guitar.

Capsule

The Advanced Audio CM47 features our very accurate and smooth AK67 capsule, a 35mm capsule with 6-micron-thick German mylar diaphragms. Its frequency response falls between those of the U47 and U67 vintage tube microphones.  The AK67 capsule goes down another ½ octave before rolling out, compared to the K47 capsule.  The CM47 also has more “air” or “sizzle” above 10kHz, allowing it to cut more easily through busy mixes without adding EQ.

Circuit

The circuit is based on the very hifi 6072 tube optimized with a two-stage Class A design.

This circuit provides a much lower output impedance with more headroom than the circuit used in the original U47. The lower output impedance provides a faster damping factor when driving the BV8 type transformer, delivering a better transient response than the original design.

Selected 6072a tubes are some of the quietest tubes made, and are much less susceptible to microphonics than the metal-clad vf14 tubes used in the original U47 tube microphone.

The dual-bobbin output transformer with its hum bucking configuration and our optimized circuit will deliver +20dBu with less than 1% distortion.

The output transformer is driven with a 2.2 ufd metal-film capacitor to take advantage of the transformer’s response down to 10Hz.

    Used on vocals and acoustic guitars, Amazing Mic!! I’m going to buy another one very soon

    I own this mic for two years now… i was looking for some Tube Mic with fair price at all for recording male voice and some acoustic instruments like acoustic guitar. Thank you Advanced Audio, I was definitely fascinated… yes it is true – well built and delivers great performance for the price…but the price is not my judge… This mic simply works for me, for my ears! …And it is worth mentioning that i had no issues at all!… definitely I am going to add some more AA mics to my arsenal, soon 🙂

    A real surprise was the comparison of my Neumann microphones versus CM 47. The quality for this fair price agrees is phenomenal.This will not be the last microphone what we buy from you. Michael Jarosch – Germany/ Yellowroomstudio / Saarbrücken

    Just thought I would let you know how pleased I am with my new CM87 and CM47. They both are wonderful sounding microphones and I have used them on numerous sessions for many different purposes. The CM47 sounded particularly great on male vocals and had such a full sound which I think is unparalleled in this price range. I recently used both of the microphones on this track below for tracked trumpet and trombone for a Eurovision Song Contest entry. The trumpet was on the CM87 and bone was on the CM47. https://youtu.be/Fv9j01veg7Q Also here is a link to a few of my projects if they interest you at all: https://youtu.be/2uJ_0eIq5zY https://youtu.be/tCdRZws8kyw https://youtu.be/2gta7p41ap4 Thanks once again for the brilliant mics – I’ve been telling everybody over here about them!!
