Creek OBH-11

Operating

Instructions

Thank you for purchasing the OBH-11 Headphone Amplifier. You are now in possession of a State of the Art product. The functions and operation of the OBH-11 are extremely simple. However, the following notes are provided to explain all aspects of its design and use.

OVERVIEW

The OBH-11 is a miniature audio amplifier, designed specifically to drive a single pair of low to medium impedance (30Ω -300Ω) headphones from a line level source. 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-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.

The OBH-11 is not designed to be connected to the speaker output of an integrated or power amplifier. Output level can be controlled by the high quality volume control on the front panel.

The Creek Audio OBH-11 and OBH-11 Black are compact headphone amplifiers designed for audiophiles seeking to enhance their listening experience with high-quality sound and exceptional performance. Known for their rich audio reproduction, these amplifiers combine advanced technology with user-friendly design to deliver remarkable fidelity.

One of the standout features of the OBH-11 series is its ability to drive a range of headphones, from low-impedance models to high-impedance counterparts, making it versatile for various listening setups. The OBH-11 boasts a powerful output stage, ensuring that even demanding headphones receive ample power for optimal performance. This results in clear sound across the entire frequency spectrum, with impressive detail and dynamics.

The OBH-11 Black takes these capabilities a step further with additional refinements, including upgraded components and improved circuit topology. Creek Audio emphasizes the importance of high-quality parts in their designs, and the OBH-11 Black is no exception, featuring premium capacitors and resistors that contribute to its superior sound clarity. The use of low-noise op-amps enhances signal integrity, allowing for a pristine audio experience.

Both models use a compact, stylish chassis that fits seamlessly into any audio setup. The front panel features a clean and intuitive design, with a volume control knob and a headphone output jack. The OBH-11 Black also includes a switchable gain setting, allowing users to tailor the output to suit their specific headphones, providing even greater flexibility and control over their listening experience.

Connectivity is another area where the OBH-11 and OBH-11 Black excel. They are equipped with line-level RCA inputs, ensuring compatibility with a wide range of audio sources, from CD players to DACs and more.
