Warm Audio WA-MPX / WA-2MPX Tube Mic Preamplifier User Manual

The WA-MPX and WA-2MPX are single‑ and dual‑channel tube microphone preamplifiers that use premium 12AX7 and 12AU7 tubes, custom CineMag transformers, and a range of tone‑shaping switches to deliver classic tape‑era warmth. Warm Audio hand‑assembles each unit in Austin, Texas, and provides a 14‑day registration window for warranty support.

This manual explains how to register the product, describes each front‑ and rear‑panel control, provides wiring diagrams for single‑ and dual‑channel configurations, lists full technical specifications, and outlines safety and warranty information.
