Operation 11
NOTE
If the input ground lift switch is used, you must ensure adequate shielding of the input wiring. If the signal source
equipment does not provide adequate shielding (i.e. a definitive connection to ground), you must disconnect the
shield from the input connector's ground pin (Pin-1) and re-connect it to the "drain" contact on the input
connector. This will ensure the shield on your input wiring actually goes to the amplifier chassis and subsequently
to earth.
DO NOT CONNECT PIN-1 DIRECTLY TO THE DRAIN CONNECTION.
You will defeat the amplifiers internal grounding scheme and possibly cause instability in the amplifier.
Always ensure that the amplifier is and the attenuators are turned when you engage this switch. This
switch should only be used when the amplifier is operated from a signal source.
NOTE: Be wary of outputs, these are often no more than floating outputs.
