See real analog levels, keep more gear connected, and spend less time rewiring when switching, comparing, or expanding your HiFi system.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-family: 'times new roman', times; font-size: 14pt;\"\u003eRead 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.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-family: 'times new roman', times; font-size: 14pt;\"\u003eLess 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. \u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-family: 'times new roman', times; font-size: 14pt;\"\u003eBring Every Track to Life: Large analog VU meters make every rise and fall in music more vivid, easy to enjoy even from your listening seat.
