[Pre-Sale] Douk Audio VU2-PRO：4‑Way Audio Selector with Accurate Analog VU Meter

Retro VU Appeal Meets Precision Metering: VU2-PRO keeps VU2's classic dual-meter appeal and flexible RCA audio switching/splitting, then steps up with calibrated level readings. See real analog levels, keep more gear connected, and spend less time rewiring when switching, comparing, or expanding your HiFi system. Read the Signal Behind the Swing: See accurate signal levels from front-end gear, making output differences and musical dynamics easier to understand without guessing by ear. Whether input levels are low or high, three meter-gain settings keep readings clear at a glance without changing the audio signal. Choose AVE for steadier average readings or PEAK to catch sudden signal peaks. Less Rewiring as Your System Grows: Keep more gear connected instead of swapping cables between setups. Connect up to four RCA sources like DACs or preamps and switch between them, or send one source to as many as four RCA outputs at once. Independent XLR pass-through adds VU metering to your balanced setup.
