1 NAD VU METER
•
The C 3050 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 is at standby
mode.
•
When the C 3050 is powered up from standby mode, this indicator
will illuminate green.
•
In cases of serious abuse of the C 3050, such as excessively low
loudspeaker impedance and short circuit, the C 3050 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 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.

The headphone socket will work in parallel with the selected
speakers. To listen to headphones only, rotate SPEAKERS knob to
OFF position.
•
The volume, tone and balance controls are operative for
headphone listening.

Use a suitable adapter to connect headphones with other types of
sockets, such as 3.5mm "personal stereo" jack plugs.
NOTE
Make certain that the volume control is turned to minimum (fully
