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