Thank you for purchasing the OBH 21/21SE headphone amplifier.
You are now in possession of a state-of-the-art product. The
functions and operation of the OBH 21/21SE are extremely simple.
The following notes are provided to explain all aspects of its design
and use.
The OBH 21 is a miniature audio amplifier, designed specifically to
drive two pairs of low to medium impedance (30
headphones from a line level source. The OBH 21SE is a high end
version using more expensive components. It is more efficient to
have a small amp do this rather than waste the power of a full size
one when only driving headphones.
The OBH 21 and 21SE are compatible with any source at line level.
For example the average output level of a CD player can be
connected directly to the input of the OBH 21/21SE just as it could
also be used in conjunction with a stand-alone pre-amplifier or
integrated amplifier which doesn't have a headphone socket.
