Creek OBH 22 Passive Pre Amplifier with Remote Control (sold)
Made In England
Product information
The Creek OBH-22 passive pre amplifier allows you to connect standard line level output items directly to your power amplifier, with simple, pure input switching and volume inbetween, without introducing any gain or distortion into the signal path. It is in effect a "control pre-amplifier".
Most modern line level sources have an output which can go directly into a power amplifier with the use of a passive pre amplifier, provided the sensitivity of the power amplifier is high enough to be driven directly from the source (your CD player, tuner etc). As such, the OBH-22 is a purist alternative to a full pre amplifier.
In addition to a standard "Pre Out" to connect to your power amplifier, the OBH-22 includes a "Tape Out" that if not used with a cassette deck, can be used to output audio to a separate headphone amplifier, such as the Creek OBH-21 or OBH-21SE.
Technical Design
The OBH-22 consists of a high quality 27mm ALPS Blue Velvet motorised potentiometer and two relays gold contact which select the desired input, together with a muting relay that shorts the signals to ground when active but is not in the signal path for normal operation.
A built-in micro-controller decodes the infra-red signals transmitted by the handset and translates them into commands which power the motorised potentiometer relays. After each operation, the micro-controller turns itself off to avoid any possibility of interfering with the main music signal. LED’s are used to indicate the status and mode of operation.
