The OBH-11 is a miniature audio amplifier, designed specifically to drive a single pair of low to medium impedance (30 Ohm -300 Ohm) headphones from a line level source. The OBH-11 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-11, 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.
Creek has re-engineered the casework of the old OBH 11, so the front panel is now much thicker and has rounded corners, new style graphics and the metal logo found on the more expensive Creek products. It is ONLY available in black and is an addition to Creek’s range of popular headphone amplifiers.
OBH Uni Power Supply
The OBH-Uni is a 15 Watt high-efficiency multi-region power supply adaptor that replaces the OBH-1 and OBH-2.
Creek has designed this to simplify the requirements for OBH products used in all countries. It is supplied with a selection of snap-on power plugs and since it is capable of working from a range of mains voltages from 100 – 240V’s, we are confident it will make life a lot easier for everyone.
We have compared the performance with that of the OBH-2 and feel that it is a good replacement. Furthermore, since it no longer works at mains frequencies (50-60Hz) it will not interfere with high gain circuits like the Phono amplifiers and it also does not draw current when connected to the mains but not being used.
We are pleased to say that it complies with the new and up-coming regulations that demand power supply adaptors to be high efficiency switching types.
