BTOER ET30 2-in-2 Out Speaker Switcher — Dual Analog VU Meters (85mm & 45mm), USB 5V Remote

The BTOER ET30 lets you switch between two amplifiers and two pairs of speakers without repeatedly plugging and unplugging cables, reducing wear on contacts and enabling smooth audio transitions. Ideal for setups that need quick source/output changes without interruption. Visual audio monitoring comes from dual analog VU meters — one 85mm and one 45mm — that add a vintage feel while providing clear level indication. Warm yellow backlighting and a retro-style metal shell create a nostalgic, eye-catching appearance in any listening environment. Internally each channel is fully isolated with independent grounds to minimize interference and crosstalk. The ET30 is compatible with a wide range of amplifiers including BTL, Class A, Class B, Class D digital amplifiers, and tube amplifiers. Powered via USB 5V and supplied with a remote control, the unit allows convenient operation from a distance. All configured settings are retained after power-off, so your preferred setup is restored automatically on next use.
