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.
WARRANTY
If within two years of the purchase date your OBH product proves to
be defective for any reason other than accident, misuse, neglect,
unauthorised modification or fair wear and tear, Creek Audio Ltd
will, at its discretion, replace the faulty parts without charge for
labour or return carriage within the U.K.This warranty is valid only
within the U.K. and given in addition to statutory rights. Service
enquiries outside the U.K. should be addressed first to the
supplying dealer and or Creek distributor/importer. Warranties
granted in these countries are entirely at the discretion of the
distributor.
The OBH 21 is a miniature audio amplifier, designed specifically to
drive two pairs of low to medium impedance (30W
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.
to 300W)
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.
