CREEK OBH-21 & OBH-21SE HEADPHONE AMPLIFIERS
Direct replacements for the successful OBH-11/11SE these latest headphone amplifiers from creek have been restyled with a brushed silver front panel and increased case depth, to keep in style with the rest of the Creek family of products. Both amplifiers now feature two headphone sockets.
The OBH-21 is a minature audio amplifier, designed specifically to drive two pairs of low to medium impedance (30ohm-300ohm) headphones from a line level source. The OBH-21SE is a high-end version using more expensive components and (OBH-2) power supply. 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-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 also 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.
