Telefunken AR-51 Overview

The AR-51 Multi-Pattern Tube Condenser Microphone from Telefunken provides a smooth mid-range, open top end, and a well-balanced low-frequency translation that make it a great choice on anything from vocals to drums to acoustic guitar and even saxophone.

The AR-51 features the TK51D capsule, a 34mm dual-membrane, edge-terminated design. This larger surface area provides an extended low end and a smoother, more open high end. This capsule brings the AR-51 sonically closer to the revered sound of the edge-terminated CK12 capsule. Additionally, the AR-51 takes the amplifier electronics of the C12 and ELA M 251E microphones. The core of this amplifier is a NOS ECC81 vacuum tube, which is coupled with the same German-built output transformer as the C12 and the ELA M 251E.

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 complement their production.

Quality Beyond Its Price Point
The AR-51 incorporates a similar capsule design and the same amplifier as the more expensive C12 and ELA M 251E microphones.
