Warm Audio WA-87jr SE Black
Configurer
The Warm Audio WA-87jr SE Black is a transformerless large-diaphragm condenser microphone that distills the iconic '87 studio sound into a streamlined, highly efficient format. Designed for modern tracking applications, the SE model sacrifices switchable polar patterns in favor of a strictly optimized fixed cardioid response, while retaining a fully discrete signal path built entirely from premium, through-hole electronic components.
Authentic K87 Capsule Engineering
Capturing the signature forward midrange and smooth top-end characteristic of classic '87-style circuits requires a meticulous approach to the transducer. The WA-87jr SE utilizes a custom single-backplate iteration of the K87-style capsule, featuring a gold-sputtered Mylar diaphragm. This precise engineering allows the microphone to translate nuanced vocal articulation and the rapid transients of acoustic instruments flawlessly, producing tracks that sit effortlessly in a dense mix without the need for heavy equalization during post-production.
Discrete FET Circuitry and Ultra-Low Noise
When tracking intimate vocal performances, voice-overs, or quiet acoustic sources, self-noise becomes a critical bottleneck. The internal architecture of the WA-87jr SE relies on genuine Toshiba FETs and WIMA film capacitors, achieving an exceptionally low self-noise floor of just 9 dBA. The transformerless output stage further guarantees rapid transient response and surgical signal clarity, keeping the low frequencies tight and strictly free from nonlinear saturation.
KEY FEATURES
- Custom K87-style single-backplate capsule delivering classic vintage warmth and midrange detail.
- Fully discrete, transformerless electronics featuring genuine Toshiba FETs and WIMA film capacitors.
