Creek OBH 21/21SE

Headphone Amplifier

Operating

Instructions

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 (30Ωto 300Ω) 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.
