Maximum Performance and Compatibility: OBH-Uni Power Supply Adaptor
OBH-Uni is a multi-region, 24V, 0.5A power supply adaptor. Creek originally developed it to simplify the requirements for selling OBH products in all countries. However, extensive listening tests and comparisons proved this high-efficiency regulated power adaptor can also extract the best performance from all of Creek's OBH products. It is supplied with three different snap-on power-plugs suitable for Europe, UK, and USA. The snap-on head uses a 2-pin, figure-8 connector, so it's possible to use a 2-pin figure-8 extension power cord with alternative mains plugs on the end. It provides a stable output from any input mains voltage range from 100 – 240V. The latest OBH-Uni draws less than 0.5W when idle or plugged-in but not used. It is also silent in operation, from zero to maximum current consumption.

Stylish Looks and Construction
Designed to complement the Creek full-sized range, OBH-21 Mk2 has an impressive solid aluminum front panel with either a silver or black finish. It is housed in a custom black metal case that is fitted with turned metal disc feet and sound-absorbing cushioned feet.
