The needle deflects in proportion to the signal amplitude (up to 500 µA full scale), giving you a real-time visual readout of your audio level — ideal for monitoring recording inputs and amplifier outputs.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What voltage does the backlight require?\u003c\/h4\u003e\n\u003cp\u003eA: The warm filament backlight runs on either DC or AC voltage in the range of 6–12V. This broad compatibility makes it easy to integrate into most DIY audio panels and enclosures without additional power conditioning.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What size panel cutout do I need to install this VU meter?\u003c\/h4\u003e\n\u003cp\u003eA: The meter housing measures 35 × 35 mm, so you will need a corresponding panel cutout of approximately that size. Always verify exact mounting dimensions against your specific enclosure before cutting.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this meter suitable for vintage audio restoration projects?\u003c\/h4\u003e\n\u003cp\u003eA: Yes — the warm filament bulb backlight and classic analog needle design make this VU meter an excellent choice for restoring or building vintage-style amplifiers, receivers, and recording consoles. Its stainless steel construction ensures longevity in both new builds and restoration projects.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does this VU panel meter measure and how does it work?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This analog VU panel meter measures audio signal levels by detecting electrical current flow through its 630 Ohm internal resistance.
