Creek OBH-21, OBH-21-SE Brochure

OBH-21/OBH21-SE HEADPHONE AMPLIFIER

The OBH-21 is a miniature audio amplifier
specifically designed to drive two pairs of low
to medium impedance (30Ω - 300Ω)
headphones from a line level source.

The OBH-21SE is a high-end version using
more expensive components and power
supply. It is more efficient to have a small
amplifier to do this than to waste the power of
a full size one when only driving headphones.

Don’t be fooled by the size - Creek has left

nothing to chance when it comes to performance.

The OBH-21 and OBH-21SE are 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-21/21SE, just
as it could be used in conjunction with a stand-alone pre-amplifier or integrated amplifier which
doesn’t have a headphone output.

The OBH-21 is not designed to be connected to the high-level speaker output of an integrated
or power amplifier. Output level is controlled by the high quality volume control on the front
panel.
