Congratulations on purchasing the Samson S•phone Headphone Amplifier! Although this unit
is designed for easy operation, we suggest you take some time out first to go through these
pages so you can fully understand how we’ve implemented a number of unique features. The
S•phone is a compact, high-quality device that allows you to monitor any stereo or monophon-
ic source signal (balanced or unbalanced) over as many as twelve separate headphones.
Providing unusually high power levels and superb audio fidelity, the S•phone is compatible with
virtually all popular headphone models. Front panel controls include a Master Input Level con-
trol and Stereo/2 Channel switch. Each headphone output has its own individual HIGH & LOW
Frequency EQ, an Insert jack, and Level control. Special output jacks on the rear panel allows
any number of S•phone units to be linked together with no loss of signal. The S•phone can be
used in a wide variety of applications, including recording studios, teaching labs, broadcast
environments, and for live performance. In this manual, you’ll find a more detailed description
of the features of the S•phone, as well as a guided tour through the front and rear panels,
step-by-step instructions for using the S•phone, a reference chart that gives impedance and
sensitivity ratings for a number of popular headphone models, and full specifications. You’ll
also find a warranty card enclosed—please don’t forget to fill it out and mail it so that you can
receive online technical support and so we can send you updated information about other
Samson products in the future.
With proper care and adequate air circulation, your S•phone will operate trouble free for many
years. We recommend you record your serial number in the space provided below for future
