X/Y StereoTelefunken Elektroakustik R-F-T M216 X-Y

X/Y Stereo Tube Condenser Stereo Microphone

The “M216 X-Y” is the third, and simplest microphone in the M216 series. Like its siblings, it is a dual-capsule tube microphone; it differs in that both capsules have fixed Cardioid pickup patterns.

The mic has twin large-diaphragm capsules stacked one atop the other. Both are the company’s model TK67, a 32mm center-terminated design modeled after Neumann’s K67 (which was a 34mm capsule). These are believed to be sourced from an overseas supplier.

The top capsule and headbasket can be rotated up to 90° with respect to the lower capsule, allowing the mic to capture X-Y stereo images with up to 90° of spread.

Note that the M216 Stereo and M216 Matrix offer additional stereo options, due to their use of one or two multipattern capsules (respectively).

The mic body contains two separate amplifier circuits (one for each capsule), two AMI BV314 output transformers, and a single twin-triode tube that is described simultaneously as a “6072a General Electric JAN” (12AY7) and “New Old Stock ECC81” (12AT7).

Telefunken USA M216 kitEach M216 microphone is supplied with a padded wooden storage case, M916 power supply, and a 10-meter Gotham Audio power cable. The mic carries a 4-year limited warranty.

The Telefunken Elektroakustik R-F-T M216 X-Y is also known as: M216 Stereo X-Y.
