Operation Guide
Please do not power on the device until all connections have been completed. 1. Prepare the following: a PH05 unit, an audio source device with a 3.5mm output, a 3.5mm to 3.5mm auxiliary cable, and headphones with a 3.5mm plug; 2. Use the 3.5mm auxiliary cable to connect the audio output interface of your source device to the input interface of the PH05;
3. Insert the headphones into any of the channel output ports on the PH05. Turn the volume knob counterclockwise to the minimum to avoid sudden high volume during music playback, which could potentially damage your hearing;
4. Connect the PH05's power interface using the 12V/1A power adapter. Then, press the power button briefly to turn on the device. The indicator light will turn orange upon powering on;
5. During use, you can quickly mute the device by briefly pressing the multifunction button. The indicator light will turn blue when muted. To cancel the mute and resume music playback, press the button again, and the indicator light will return to orange.
Frequently Asked Questions
1. Is it possible to use five AUX inputs with a single headphone output? The PH05 is designed for one input with five outputs and does not support reverse usage.
2. Can the PH05 be used for microphone calls? The PH05 does not support microphone signal input, and therefore it cannot be used for calls.
3. What should I do if only one side of the headphones has sound output? a. Please ensure that the 3.5mm audio cable you are using is a stereo cable, not a mono cable; b. If the issue of no sound output on one side occurs in all five outputs, it may be a problem with the headphones. If it happens with only one output, please contact customer service for product exchange or return.
