Douk Audio Box VU Meter Audio Switcher with IR Remote 2-Zone Amp/Speaker Selector,

------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ [VU102 Amplifier/Speaker Selector] Two operating modes (2-IN-1-OUT/1-IN-2-OUT), with A/B channel switching button.

[Note] 1. For safer and faster delivery, the remote control may not include batteries (2 * AAA). Also, the DC 5V power adapter is not included, so please prepare it yourself. 2. In 1-IN-2-OUT mode, A/B channels (2 sets of speakers) can be used at the same time. However, in 2-IN-1-OUT mode, you cannot use two amplifiers at the same time. Otherwise, the amplifier may be damaged. 3. There may be relatively loud noise when switching A/B channels, which is normal.
