The Fosi Audio PH05 5-channel headphone splitter amplifier is a device that provides a stereo signal via 5 separate outputs, each with independent volume control. Each output has its own independent amplification and offers an output power of 310mW under 32 ohms, enabling you to drive IEMs or headphones with impedances ranging from 16 to 300 ohms. In addition to 5 independent potentiometers, there's also a master volume control and a mute button for total control of the Fosi Audio PH05. Input is via 3.5mm AUX jack, while the 5 outputs are via 3.5mm headphone jack. Thanks to its excellent technical performance, the PH05 can be used in a wide range of scenarios: music production, podcasting, group listening, etc.
The Fosi Audio PH05 is based on an OPA NE5532 chip, giving it an output power of up to 310mW under 32 ohms per 3.5mm headphone output. This enables it to drive a wide range of headphones and in-ear monitors, from 16 ohm to 300 ohms impedance.
A large potentiometer controls all 5 outputs.
Each small potentiometer is dedicated to a headphone output for a listening experience tailored to each user.
A button with LED indication mutes the 5 headphone outputs.
Suitable for studio use, the Fosi Audio PH05's internal circuitry is optimized for audiophile performance. It features an SNR of 105dB, a THD+N of 0.001% and a noise figure of 25μV.
