Douk Audio VU102 2-Zone Amplifier / Speaker Selector Box with VU Meter and IR Remote Review

The Douk Audio VU102 is a speaker and amplifier selector box priced at $99.99. It sits in the switching-accessory category of hi-fi gear and finally solves the cable-chasing problem for listeners who own two amplifiers or two pairs of speakers: instead of re-plugging banana cables every time you want to compare, you press the A/B button.

The VU102 works in two directions. In 2-IN-1-OUT mode it takes two amplifiers and feeds one pair of speakers, so you can A/B two power amps through the same speakers. In 1-IN-2-OUT mode it takes one amplifier and feeds either or both pairs of speakers. Each channel passes up to 200W and uses a fully isolated design with independent grounds, so the channels do not interfere with each other. Douk Audio lists compatibility with BTL, Class A, Class AB, Class B, Class D and tube amplifiers, and there is a built-in protection load for both amplifiers and speakers.

The front panel carries a 72 x 32mm VU meter that swings with the music, and an IR remote covers all settings from across the room. Status is shown with clear indicators, and the settings are saved after shutdown so the box returns to your last configuration. Power comes from USB Type-C at DC 5V (1A or higher). The case is finished in black and measures 149 x 105 x 75mm at 664g.

Douk Audio attaches three operating notes. First, in 2-IN-1-OUT mode the two pairs of speakers can play simultaneously in 1-IN-2-OUT mode, but two amplifiers must never work at the same time in 2-IN-1-OUT mode or they may be damaged. Second, there is a relatively loud noise when switching A/B channels, which is normal. Third, the remote may ship without its 2 x AAA batteries, and no DC 5V power adapter is included with the box.
