Creek OBH-1
The function of the OBH-18 is to boost the level and correct the frequency
response of a low level signal coming from a phono pick-up on a conventional
turntable. The signal required by most modern amplifiers is described as being
'LINE' level, which is, in technical terms, between 200 and 500 milli-Volts with a flat
frequency response.
Unless your amplifier has a specific 'Phono' or Disc input, the level will be too low
and the frequency response will be wrong.
The Creek OBH-18 phono pre-amplifier is designed to boost the signal and intro-
duce an R.I.A.A. frequency response characteristic.
INPUT AND OUTPUT CONNECTION
The output from the turntable is normally terminated on two
'Phono' plugs or RCA jacks. The level is dependent on the
type of cartridge used, and in the case of moving magnet
will normally be around 2 - 5 milli-Volts.
Most moving magnet cartridges will be properly matched by
using the OBH-18. By plugging the signal leads from your
turntable into the OBH-18 input, the signal will be boosted
to 'LINE' level at its output. To prevent hum pick-up, it may
be necessary to join the turntable's earth lead to the OBH-
18 ground terminal.
The output from the OBH-18 can be connected to most
integrated amplifier's and pre-amplifier's line inputs via a
regular Phono to Phono (RCA to RCA) stereo interconnect
lead.
