Supporting both VU standard mode and EQ spectrum mode, it provides accurate needle response across a wide frequency range while maintaining high input impedance to minimize impact on source audio. With adjustable brightness, remote control functionality, and power-off data storage, it offers flexible operation and reliable performance. Compatible with various audio sources including computers, mobile phones, decoders, CD and DVD players, this unit operates on 12V DC power and includes a charger, remote control, and user manual for complete setup.\u003c\/p\u003e\u003cp\u003eKey Features\u003c\/p\u003e\u003cp\u003eThe unit supports dual XLR stereo input ports and operates within a 100–240V input range, delivering stable 12VDC 1A output. It handles a maximum effective audio input voltage of 1.1Vrms, with 2.5Vrms as the upper limit to prevent damage. Monitoring frequency ranges include 20–20KHz in VU mode and 100–10KHz in EQ mode. A 50KΩ high input impedance ensures minimal interference with incoming audio signals. The meter features three adjustable gain levels at -3dB, 0dB, and +3dB to control needle swing without affecting source audio output. Users can select between LINE IN sources or a built-in microphone pickup, and adjust display brightness across four levels. The device supports remote operation using two AAA batteries and retains settings after power off. For optimal use, it should not be connected directly to speaker outputs, and only a 12VDC power supply with at least 1A current is recommended. Factory calibration is set to VU mode at 0dB corresponding to 0.775RMS 1KHz, with manual recalibration available if different voltage standards are required.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"n\/a","offer_id":43161451855956,"sku":"B0BD33KS3L","price":354.04,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0631\/9715\/1316\/files\/b20fc8074edaa63c17fd21489760.jpg?v=1772463625","url":"https:\/\/6at0be-md.myshopify.com\/products\/4-way-vu-meter-3-gain-dc-12v-1a-power-off-data-storage-analog-sound-level-meter-for-audio-equipment-us-plug","provider":"My Store","version":"1.0","type":"link"}
