CardioidADK Cremona 251-Au

Cardioid Condenser Microphone

The Cremona 251 Au is a Cardioid FET condenser with a large-diaphragm capsule and transformer-coupled output, designed to sound like a ElaM 251, albeit in a solid-state edition.

It was introduced around 2009 as part of ADK’s “AU” series of Custom Shop microphones; it was replaced in 2013 with the release of the T-Fet series of multipattern mics.

GK251 CapsuleThe 251 Au uses the GK251 capsule from ADK’s 3-Zigma product line; this is a capsule voiced to sound like an AKG CK-12 capsule from the early 1950’s.

As is true of all the AU series FET mics, the 251 version used high-quality components including film capacitors from Wima and an Oxford/OEP output transformer.

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

  • On the rear of the mic, the first of two 3-position switch 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.

The body is engraved with the “ADK Custom Shop” logo and the model name of the mic.

The Cremona 251 sounds amazing on female vocals… In addition, I found that the mic sounds great on electric guitar, percussion, and cello.
