Introduction

Thank you very much for purchasing the Fostex PH-100 headphone amplifier/distribu- tor. The PH-100 can distribute the input signal accepted by any of three pairs of stereo input connectors to 10 headphones whose level can be adjusted independently. It also provides the 10-input, 10-output matrix box function which allows independent feed for each headphone. The PH-100 is equipped with two stereo pairs of balanced inputs (+4 dBu XLR-3-31 connectors and -10 dBV phone jacks), as well as a stereo pair of unbalanced inputs ( -10 dBV RCA pin jacks). It also provides the AUX IN jacks which are useful when using the PH-100 as a cue box.

In addition, you can cascade PH-100s, making more than 10 persons possible to monitor the same stereo source.

Please read through this manual before using, and always keep it nearby.
