Local highlights: everything for convenience

1. Infrared remote control key switch: The machine has a built-in infrared receiving device, equipped with a remote control, which can remotely switch the sound source; the switch button is also provided on the machine, even if the remote control cannot be found occasionally, it is very convenient to complete the sound source switching operation.

2. Power-off memory function: The memory retains the input signal channel of the last power-off when the power is turned on.

3. Two-way 3 in 1 out or 1 in 3 out: 3 audio sources can correspond to 1 post level, or 1 audio source can correspond to 3 post levels (used to compare the output device sound quality or the output device sound quality is very convenient)

4. High-quality materials: ensure that the signal transmission is free of any attenuation and distortion: the HIFI standard selection of devices is completed, there is no need to pursue the improvement of sound quality, but it must not cause attenuation and distortion; the shell body is made of aluminum alloy, which is The messy signal shielding function is not small.

5. Experience effect: The machine itself does not have any noise floor; when switching the sound channel, it is clean, smooth and natural, without any delay; at the same time, when switching the sound source, there will be no current impact on the speaker and no noise.
