ADK Microphones HA-FX Head Amp

Controls: 3-way pad, 3-way high-pass filter

I/O: XLR output; accepts interchangeable 3 Zigma capsule modules (C-LOL large-diaphragm or SD small-diaphragm)

Notes: FLAG - this is a standalone microphone head-amp BODY for the 3 Zigma modular capsule system (not a general-purpose channel preamp for line/mic sources). Sold separately from capsules for owners building/expanding a 3 Zigma kit. adkmic.com product page content did not reliably resolve (site is JS-rendered and returned templated boilerplate); price and detailed specs not confirmed from a reliable source, so left blank rather than guessed. Marketed as 'ultra-high-SPL, transformer-coupled' with 3-way pad/HPF per ADK product copy and Front End Audio kit descriptions.
