INSTALLATION

POWER SUPPLY

A Ground Lift switch is provi- ded to assist in the eliminati-

on of ground loop problems.

ce is not driving Optimizer´s filters sufficiently with the pro- viso that the Peak LED on the front panel is not continually flashing. This will achieve equalization at a lower signal level and will result in a more intensely processed sound. Note: this level change also effects the signal when the filters are in bypass, so you will loose direct comparability as the listening level changes.

Based around a toroidal transformer, the integral power supply is designed to minimize induced hum and noise due to the non existence of an air-gap. The primary voltage may be selected between 230V/50Hz and 115V/60Hz by means of a recessed slide switch on the rear panel.

A Ground Lift switch is provided to assist in the eliminati- on of ground loop induced hum in complex installations. If ground loop problems remain after activating the Ground Lift switch, do not disconnect the mains earth. Instead try disconnecting the signal screen at the end the cables that connect the outputs of the Optimizer to the patchbay. If such measures are necessary, balanced operation is recommen- ded.

When the Ground Lift switch is set off, the circuit ground is connected to the chassis ground.

The mains fuse should be rated at 800mA. A detachable 3-wire, U-ground power cord is included in the packaging.
