Product Highlights

Product Description

The R-F-T AR-51 is a high quality tube condenser that draws inspiration from the classic C12 and ELA M 251E microphones. It provides a smooth mid-range, open top end, and solid, well-balanced low frequency translation.

Featuring edge terminated TK51D capsule, a European NOS (New Old Stock) ECC81 / 12AT7 vacuum tube and newly manufactured Haufe T14/1 output transformer, the AR-51 captures the same clarity as its predecessors and provides similar sonic characteristics, with its own unique distinctions.

The AR-51 features the same amplifier electronics of the Austrian designed C12 and ELA M 251E microphones and pairs them with a dual sided, 26.5 mm large diaphragm TK51D capsule. At the core of the R-F-T AR-51 amplifier is a NOS ECC81 / 12AT7 vacuum tube, which is coupled with the same German built Haufe T14/1 output transformer found in the C12 and ELA M 251E.

The AR-51’s steel headgrille mesh and brass base ring are finished in black nickel plating, giving the microphone a unique look and vibe. The aluminum body tube is finished in a grey protective hard coat and is engraved with the microphone model name and serial number. An antique nickel plated TELEFUNKEN diamond logo badge is featured on the front of the microphone. The power supply is also finished in a black protective coating.

Each AR-51 microphone comes complete with M 901 power supply, M 801 25’ dual-shielded TX-7 tube microphone cable, M701 elastic shock mount, wooden microphone box and a Flight Case: HC01 - Hard Shell Protective Case.

Product Review

American musical supply is great to deal with!! and the AR 51 Telefunken is amazing!! I've worked as a recording engineer for years with access many of the vintage like telefunken U47's and new high end mic's and this holds it's own. I bought this for my personal writing studio and really could be happier. I'm using this mostly for acoustic guitar and male vocals it's very open and smooth with full tight low ends. I'm truly getting the true sound of my Taylor when I listen back like I'm playing it and it's in my lap, with very little string noise etc. So natural sounding, no hyped mids etc.
