The output from the OBH-8/9 can be connected to most integrated and preamplifier's line inputs via a regular Phono to Phono (RCA to RCA) stereo interconnect lead. POWER SUPPLY REQUIREMENTS In common with all electrical appliances, the OBH-8/9 requires a power source. The requirement for the OBH-8/9 is for 24 Volts DC at 30 mill! Amps current, or higher. An OBH-1 standard power supply, or OBH-2 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 front panel. N.B. Due to the inherent muting circuitry in the OBH-8 & 9 the signal will take a few seconds to be heard after the power is switched on. Keep the main amp's volume control at minimum to avoid hearing any unpleasant noises during the on/off phase. WIRING THE OBH-8 AND OBH-9 Rear of Amplifier Note 1. The OBH should be placed away from transformer hum fields for the lowest noise operation. Note 2. It is also necessary for the OBH to be 'burned-in' for at least 24 hours before its full sound quality potential can be realised.
