Packing List
Thank you for purchasing the Fosi Audio PH05 HiFi headphone amplifier!
The PH05 is a high-performance five-channel headphone amplifier that
utilizes the Texas Instruments NE5532 operational amplifier chip, relying
on high-quality capacitors, inductors, and resistors to achieve stable and
pure high-fidelity audio output. The PH05 features five 3.5mm audio
output ports, allowing for powering up to 5 pairs of headphones and up to
5 independent volumes, with outstanding audio quality. Each channel
provides a rated output power of 310mW (32Ω load), and the volume of
the five output channels can be adjusted independently, ensuring
consistent sound quality even with headphones of various impedances.
The PH05 also features a one-touch mute function for quick and
convenient switching. Designed specifically for audiophiles, this compact
headphone amplifier is sure to provide you with a true HiFi music
experience.

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.
