Warm Tips:

• Channel 1/2 can work at the same time. It is recommended to use this function in 1-IN-2-OUT mode, that means connect one amplifier and two pairs of speakers. Amplifiers may be damaged if use Channel 1/2 input at the same time.
• In OFF state, default disconnect 1&2 terminals from I/O interface, it is equivalent to mute. And 1 and 2 will be connected to the built-in load protection at the same time.
• Without DC 5V power adapter, please preapre it by yourself.4.For safer and faster delivery, the remote control without batteries(2*AAA), please prepare it by yourself.

• 2-way amplifier/speaker selector: Both working modes (2-IN-1-OUT / 1-IN-2-OUT), with A/B channel select button, convenient to compare the sound quality of 2 pairs of different speakers or 2PCS power amplifiers without plugging in and out cables repeatedly to avoid wearing the contact point of the sockets.
