POWER SUPPLY REQUIREMENTS

In common with all electrical appliances, the OBH-18 requires a power

source.

The requirement for the OBH-18 is for 24 Volts DC at 30 milli Amps current.

A Creek OBH-1 high grade power supply, dedicated for the local voltage and

plug type, has been provided. It has a thin cable exiting from it, with a

2.1mm positive centre pin DC power jack fitted on the other end. It should

be connected to the Phono amp via the DC inlet on its rear panel.

To operate the phono amp it is necessary to switch-on the unit by pushing

the power button on the rear panel. It may be left switched on permanently

as it draws very little power.

N.B.

Due to the inherent muting circuitry in the OBH-18 the signal will

take a few seconds to be heard after the power is switched on.

Keep the main amplifier's volume control at minimum to avoid

hearing any unpleasant noises during the on/off phase.

CONNECTIONS

With its enhanced drive capability coupled with lower output impedance, the

OBH-18 phono pre-amplifier can now drive longer cables than its predeces-

sor, the OBH-8.

OUTPUT

The output impedance of the OBH-18 is < 750 Ω, and it can be used to drive

long interconnects, without loss, provided they are not high capacitance

types.

WIRING THE OBH-18

Note 1.

The OBH-18 should be placed away from power supply hum fields

for the lowest noise operation.

Note 2.

It is necessary for the OBH-18 to be 'burned-in' for at least 24 hours

before its full sound quality potential can be realised.
