ADK Hamburg 67-T

Multi-Pattern Condenser Microphone

The Hamburg 67-T is a multipattern FET condenser with a large-diaphragm capsule and a transformer-coupled output. It was introduced in 2013 as part of ADK’s “T-Fet” series of “tripolar” multipattern mics, as a revision to the fixed Cardioid Hamburg 67-Au (introduced in 2010), itself a rebranding of the Hamburg II Au (introduced in 2007).

The 67-T uses the GK67 capsule from ADK’s 3-Zigma product line. The GK67 is a dual-backplate capsule designed to sound like a “mint” Neumann U67.

The mic’s circuit is made with high-quality parts, including Wima capacitors, a premium JFET from Phillips/Norelco, and an Oxford/OEP output transformer. The same components can be found in all five T-Fet models.

Three switches located below the headbasket allow for multiple configuration options:

A 3-way switch on the front of the microphone allows selection of Cardioid, Omni, or Figure-8 polar patterns.

On the rear of the mic, the first of two 3-position switches allows selection of two high-pass filters: -6dB/octave at either 100Hz or 160Hz.

A second 3-way switch controls the input pad: 0dB, -8dB, or -16dB.
