Creek Audio OBH-11 - Manual

Thank you for purchasing the OBH-11 Headphone Amplifier. You are now in
possession of a State of the Art product. The functions and operation of the OBH-11
are extremely simple. However, the following notes are provided to explain all
aspects of its design and use.
OVERVIEW
The OBH-11 is a miniature audio amplifier, designed
specifically to drive a single pair of low to medium
impedance (30
Ω -300Ω) headphones from a line level
source. It is more efficient to have a small amp to do
this rather than waste the power of a full size one when
only driving headphones.
The OBH-11 is compatible with any source at line level.
For example: an average output level CD player can be
connected directly to the input of the OBH-11, just as it
could also be used in conjunction with a stand-alone
pre-amplifier or integrated amplifier which doesn't have
a headphone output.
The OBH-11 is not designed to be connected to the
speaker output of an integrated or power amplifier.
Output level can be controlled by the high quality
volume control on the front panel.
