Known for its rich analog character and musical saturation, the WA-MPX delivers the same vintage-inspired warmth and depth that defined classic recordings from artists such as Elvis Presley, Les Paul, and Bing Crosby, while remaining equally relevant in modern studio production.\u003c\/p\u003e\u003cvideo controls width=\"100%\"\u003e\n  \u003csource src=\"https:\/\/cdn.shopify.com\/videos\/c\/o\/v\/909bc4b1e2994b37a7b79547d69fcb87.mp4\"\u003e\u003c\/video\u003e\n\u003cp\u003eBuilt for exceptional power and tonal flexibility, the WA-MPX delivers up to 300V of operating power and 90dB of tube gain, allowing it to produce both pristine clean amplification and rich harmonic saturation when driven. This wide gain range makes it ideal for shaping everything from subtle vocal presence to heavily saturated analog textures, giving engineers full control over dynamic tone shaping in professional recording environments.\u003c\/p\u003e\n\u003cp\u003eEngineered with premium handwired construction, the WA-MPX features three high-quality tubes per channel paired with custom-wound CineMag USA transformers for authentic vintage response and depth. Its selectable all-analog tape saturation circuitry recreates classic reel-to-reel character at 15 IPS, while onboard hi-pass (80Hz) and low-pass (2kHz) filters allow precise tonal refinement. Carefully hand-tested in Austin, Texas, the WA-MPX delivers true vintage tone with modern reliability for professional studios and serious creators.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesign: \u003c\/strong\u003eFully Discrete, Hand-Built\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChannels: \u003c\/strong\u003e2 (Stereo\/Mono Operation)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTube Configuration: \u003c\/strong\u003e3 Tubes per Channel (2×12AX7, 1×12AU7)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGain: \u003c\/strong\u003e90 dB Analog Tube Gain per Channel\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Gain Mode: \u003c\/strong\u003e+20 dB (70 dB to 90 dB)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTape Saturation: \u003c\/strong\u003eSelectable Harmonic Distortion \u0026amp; Compression\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTransformers: \u003c\/strong\u003eCustom-Wound Large-Core CineMag USA\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMic Input Impedance: \u003c\/strong\u003e600Ω Transformer (6000Ω Rated)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMic Input (Tone Engaged): \u003c\/strong\u003e150Ω Transformer (1500Ω Rated)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Attenuator: \u003c\/strong\u003e600Ω\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhantom Power: \u003c\/strong\u003e48V\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePolarity Switch: \u003c\/strong\u003eYes\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTone Control: \u003c\/strong\u003eVariable Input Transformer Impedance\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh-Pass Filter: \u003c\/strong\u003e80 Hz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLow-Pass Filter: \u003c\/strong\u003e2 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInputs: \u003c\/strong\u003eXLR Mic, TS Instrument, TRS Line\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutputs: \u003c\/strong\u003eXLR \/ TRS Line Level\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVU Meter: \u003c\/strong\u003eLevel Indication\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response: \u003c\/strong\u003e20 Hz – 20 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChassis: \u003c\/strong\u003eAluminum Faceplate, Steel Body\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKnobs: \u003c\/strong\u003eVintage Bakelite-Style\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Supply: \u003c\/strong\u003eInternal IEC 115V\/230V\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Weight: \u003c\/strong\u003e9 lbs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Dimensions (L x W x H): \u003c\/strong\u003e19 x 8.75 x 3.5 in\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Weight: \u003c\/strong\u003e11 lbs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Dimensions (L x W x H): \u003c\/strong\u003e24.5 x 11.25 x 5.87 in\u003c\/p\u003e","brand":"Warm Audio","offers":[{"title":"Default Title","offer_id":47366949372157,"sku":"H-WARM-MPX","price":799.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/2308\/3005\/files\/2106624.jpg?v=1775840460","url":"https:\/\/hollywooddj.com\/products\/warm-audio-wa-mpx-single-channel-tube-mic-preamp","provider":"Hollywood DJ","version":"1.0","type":"link"}
