Warm Audio WA-47jr FET Condenser Microphone


The WA-47jr FET offers one of the most coveted classic microphone capsule designs in an affordable microphone circuit. The WA-47jr FET uses a high quality discrete transformerless circuit with Toshiba FET’s, Wima film capacitors and Panasonic electrolytic capacitors. The WA-47jr FET brings the tone and character of the classic '47 style microphone to you through the most critical component (its capsule) and is able to maintain an aggressive price-point by simplifying the rest of the circuit topology. The WA-47jr FET’s simplified circuit is in no way a low-quality circuit but is simpler to build and uses fewer components than a vintage tube microphone, which allows Warm Audio to offer it at such a bargain price. The WA-47jr FET uses the same capsule as Warm Audio's flag-ship WA-47 tube microphone and sounds wildly similar to the WA-47.

 

Key Features:

  • Pattern Select Switch: This switch selects the polar pattern for the WA-47jr FET’s capsule. The three polar pattern options are: Omnidirectional, Cardioid, and Figure-Of-Eight.
  • XLR Output: The WA-47jr FET’s output is a balanced, gold-contact 3-pin XLR that accepts a standard XLR to XLR shielded microphone cable.
  • High Pass Filter Switch: This switch engages a 70hz high pass filter for reducing rumble and other subsonic information.
  • -10dB Pad Switch: This switch engages a -10dB pad within the active circuitry.
