Palladium VPA series II Installation
Remove all packing materials. Check that all foam and plastic padding has been removed.
Screw the equipment into a 19" rack. Connect all cables.
Always disconnect from electric mains power supply before cleaning or servicing.
Damages caused by non-observance are not subject to warranty.
Set Up and Operation
Before plugging the unit in, always make sure that the power supply matches the product specification
voltage. Do not attempt to operate a 120V specification product on 240V power, or vice versa.
Do not supply power before all components of the system are set up and connected properly.
Low Impedance Speaker Output: 8Ω
The low impedance 8Ω terminal is for connecting of a few large-output speakers, when constant-voltage
speaker systems are unnecessary or the distance between the amplifier and the speakers is below 50m.
The total speaker load impedance must be matched to the output impedance (8Ω) of the amplifier for
the most efficient power-transfer.
Be sure that total impedance of speakers is above 8Ω however; do not raise the amplifier’s output power
above the allowable input power of the speaker. If the amplifier’s output power should be raised above
the maximum, the speakers could be damaged.

Connection Input
The balanced phone jack inputs have a nominal impedance of 20 KΩ (10KΩ with unbalanced wiring)
and will accept the line level output of most devices. The correct input depends on 2 factors: (1) whether
the input signals are balanced or unbalanced, and (2) whether the signal source floats or has ground
reference.
Connecting Power
The actual current draw, the amplifier demands from the AC mains, depends on many factors (its load,
output level or the crest factor of its program material).
The power requirement is rated under typical music conditions, with both channels driven so those peaks
are just at the clipping point.
