While TELEFUNKEN Elektroakustik is well known for our historic recreation microphones, but as we all know those recreations are intended for the 'upper crust' of the recording industry who can afford the best of the best.

With this in mind we created the R-F-T Series of microphones as an affordable solution that delivers amazing tone, ultimate application flexibility at a price anyone who is serious about recording can afford.

The AR-51 is the culmination of this ideal. For the AR-51 we took the amplifier electronics of a C-12 and ELA M 251E and married them to an offshore capsule and power supply so we can bring the best of both worlds together for what are destined to become the classics of tomorrow.

While the capsule is built off shore, it is tested to very high tolerances for consistency in our Connecticut based US laboratory. The capsule is then coupled to a slightly tweezed classic amplifier. The core of this amplifier is NOS [New Old Stock] ECC81 vacuum tube which is coupled the same German built output transformer you will find in our far more expensive C-12 and ELA M 251E.

In use, the R-F-T AR-51 is a fantastic utility mic!! Its smooth mid-range, open top end, and solid well-balanced low frequency translation make it a great choice on anything from vocals to drums and percussion to acoustic guitar to saxophone. There are 1000 more uses, but we think you get the idea that this is indeed a remarkably versatile microphone.

The remote pattern selector (located on the power supply) provides 9 different polar patterns, giving the user a myriad of choices for how to record the source sound in a manner that will best compliment their production.

You can start your path to sonic euphoria by contacting your favorite TELEFUNKEN Elektroakustik reseller and requesting a demo of the R-F-T AR-51. It is sure to put a smile on your face without putting too much of a dent in your wallet.
