The core problem it addresses is RF and WiFi interference entering the high-voltage path in conventional tube mic PSU designs and degrading tube and capsule performance. Wunder's solution is a high-voltage path that runs constant current, balanced against a shunt regulator — the result is a completely clean DC voltage delivered to the microphone with no RF or WiFi interference reaching the signal chain.\u003c\/p\u003e\n\n  \u003ch3\u003eProprietary High-Voltage Path and Voltage Regulation\u003c\/h3\u003e\n  \u003cp\u003eThe constant-current high-voltage architecture with shunt regulation eliminates AC ripple and RF interference at a level unavailable in standard transformer-based PSU designs. Internal voltage trimming is handled by 30-turn precision potentiometers — most PSU designs lack voltage adjustment entirely, and those that include it typically use single-turn pots prone to drift over time. The dual-pole neutral-fusing design accepts any mains voltage worldwide without requiring jumper changes or manual voltage selection. The pattern switch version uses a military-spec Grayhill switch for the most reliable directional pattern control — the same Grayhill specification Wunder Audio uses in its console switching. Available configurations include a standard version, a version with pattern switch, and an optional stereo version. On special order, the PSU can be configured to run with most tube condenser microphones regardless of manufacturer.\u003c\/p\u003e\n\n  \u003ch3\u003eCompatibility with Wunder Audio and Vintage Microphones\u003c\/h3\u003e\n  \u003cp\u003eThis PSU ships as standard with all Wunder Audio tube condenser microphones — CM7 Suprema, CM12 Suprema, CM49 Suprema, CM50 Suprema, CM67, and ELA M 251. Every microphone in that line relies on this generation of PSU for clean, stable DC delivery to the tube and capsule with full RF shielding. On special order, the unit can be configured to power most tube microphones from other manufacturers, making it a practical upgrade path for engineers running vintage or third-party tube mics where the original PSU is aging or inadequate for modern RF-dense studio environments.\u003c\/p\u003e\n\n  \u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eProprietary high-voltage path: constant current balanced against a shunt regulator — no AC ripple, full RF and WiFi interference elimination\u003c\/li\u003e\n    \u003cli\u003e30-turn precision potentiometers for fine voltage adjustment on all supply rails\u003c\/li\u003e\n    \u003cli\u003eDual-pole neutral-fusing design — worldwide mains voltage compatibility, no jumper required\u003c\/li\u003e\n    \u003cli\u003eAvailable versions: standard, with pattern switch, stereo (optional)\u003c\/li\u003e\n    \u003cli\u003ePattern switch: military-spec Grayhill (switchable version)\u003c\/li\u003e\n    \u003cli\u003eSpecial-order configuration for most tube condenser microphones from other manufacturers\u003c\/li\u003e\n    \u003cli\u003eStandard PSU for Wunder Audio tube mics: CM7 S, CM12 S, CM49 S, CM50 S, CM67, ELA M 251\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eType: power supply unit for tube condenser microphones\u003c\/li\u003e\n    \u003cli\u003eArchitecture: constant-current high-voltage path with shunt regulator\u003c\/li\u003e\n    \u003cli\u003eInterference rejection: full RF and WiFi elimination\u003c\/li\u003e\n    \u003cli\u003eVoltage adjustment: 30-turn precision potentiometers (all supply rails)\u003c\/li\u003e\n    \u003cli\u003eMains input: universal — dual-pole neutral-fusing, no jumper setting required\u003c\/li\u003e\n    \u003cli\u003eAvailable versions: standard \/ with pattern switch \/ stereo (optional)\u003c\/li\u003e\n    \u003cli\u003ePattern switch: military-spec Grayhill (switchable version)\u003c\/li\u003e\n    \u003cli\u003eCompatibility: Wunder Audio CM7 S, CM12 S, CM49 S, CM50 S, CM67, ELA M 251; special-order configuration for most third-party tube condenser microphones\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Wunder Audio","offers":[{"title":"Default Title","offer_id":53670069338449,"sku":"41725","price":477.66,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/WunderAudioTubeMicPowerSupply.jpg?v=1778416683","url":"https:\/\/wrdtunes.com\/en-fr\/products\/wunder-audio-tube-mic-power-supply","provider":"Wired Tunes","version":"1.0","type":"link"}
