Low Impedance Speaker Output: 8
The low impedance 8
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 (8
) of the amplifier for the
most efficient power-transfer.
Be sure that total impedance of speakers is above 8
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 K
(10K
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.
Indicators
The Palladium features 3 front LED indicators per channel: Clip, Signal and Power. These LED indicators
inform the user of each channel’s operating status and warn of possible abnormal conditions.
Clip LED
A channel’s red clip LED will light dimly at the onset of clipping and increase in brilliance, as clipping
becomes more severe, staying on until the clipping ceases. If the LED is flashing quickly and intermittently,
the channel is just at the clip threshold, while a steady, bright glow means the amp is fully clipped.
Reduce the gain to prevent severely clipped waveforms reaching the speakers.
Signal LED
This LED will light more insense if the input signal increases.
