ADK Microphones Z-251 Multi-Pattern Tube Condenser Microphone


The ADK Z-251 is a class-A 9-polar pattern large diaphragm valve studio microphone. It is a recreation of the infamous Ela M 251. The current ADK Z-251, is meticulously handcrafted in the USA, and is arguably the closest thing possible to the beautiful silky sound of the classic - just minus the noise! At around 1/3 of the price of the current Telefunken 251, the Z-251 is a steal! Have a listen to some comparisons here.


    • ADK Microphones Z-251 Features:

      The ADK Z-Mod Tube Microphones are Class A (Discrete) 9 Polar-Pattern Tube (Valve) Condenser Microphones hand-built as “One-Offs” using a custom Belgium-Designed PC Board built with Hi-Fi methods and materials, using a “No-Corners-Cut” approach. Features Hand-Selected Valve, Top-of-the-Line Components (like a Swedish Lundahl Transformer) with ADK Designed Capsules from the Custom Shop “Capsule-Bank”.

      The Z-Mod-251 has a silky, ambient ‘air-band’ boost, similar to a famous Vintage Austrian Tube Microphone. The golden-ears can’t tell it’s not vintage, except for the low-noise and great range!

      It took our design-team five years to put the “DNA” of each Classic Valve Mic into the capsule tonality. We took an additional two years beta-testing Transformer Combinations for each of the five Capsules. We enlisted the help of the most respected ‘bat-ears’ in the recording industry, including the late, great Mike Shipley, Chuck Ainlay, and Ronny Brookshire, etc. We ended up selecting an American, a Swedish, an English and a German Transformer builder.
