1 NAD VU METER
•
The C 3050 LE is equipped with a pair of Power meters that
monitors the Input Signal or Speaker Output levels.
•
Both Power meters are calibrated in Watts and dB (decibel) that
corresponds to an 8-ohm load.
•
Refer also to item about VU METER in the IDENTIFICATION OF
CONTROLS – REAR PANEL.
2 POWER LED INDICATOR
•
This indicator will light up amber when the C 3050 LE is at standby
mode.
•
When the C 3050 LE is powered up from standby mode, this
indicator will illuminate green.
•
In cases of serious abuse of the C 3050 LE, such as excessively low
loudspeaker impedance and short circuit, the C 3050 LE will engage
its Protection circuitry, indicated by the Power LED turning from
green to red and the sound being muted.
In such Protection circuit scenario, turn OFF the C 3050 LE via the
rear panel POWER switch. Wait for it to cool down and/or check the
speaker connections. Once the cause for the protection circuitry
to engage has been removed, switch ON the rear panel POWER
switch. Then press the front panel POWER button to resume normal
operation.
