Adjusting Power Meter Modes
The Evolution One amplifier uses microprocessors to monitor RMS output voltage
and current signals. This information is output to a custom front panel power
meter (6) (7), which displays an accurate power measurement for the selected
meter range on the power meter scale (6). The power meter has 4 modes of opera-
tion accessed by the meter range button (12):
50 WATT
range
, 500 WATT
range
, 5000
WATT

,
and
OFF.
There are two ways to cycles between the operational modes:
Press the meter range button, located underneath the bottom right edge of the
amplifier chassis front panel or,
Press the select key (
SEL
) on the Evolution Two preamplifier, on another Krell pream-
plifier, or on the Universal Krell Touch Screen Remote.
Power Meter Range and Power Meter Wand Action
The power meter (6) (7) enables you to monitor the power output of the Evolution
One amplifier. The 500 Watt scale is the factory default. The 50 Watt scale range is
the most sensitive, and displays the smallest changes in power output, with the
greatest physical movement of the power meter wand (7). Conversely, the 5000
Watt scale is the least sensitive, and displays the largest changes in power output,
with the smallest physical movement of the power meter wand.
