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.

3 PHONES

• 

A 1/4” stereo jack socket is supplied for headphone listening and 
will work with conventional headphones of any impedance. 

• 

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 
counterclockwise with Volume Level LED Indicator only at amber color) 
before connecting or disconnecting headphones. Listening at high 
levels can damage your hearing.

4  POWER BUTTON 

• 

With the rear panel POWER switch set to ON position, press this 
button to power up the C 3050 from standby mode. The Power LED 

indicator will turn from amber to green.  The NAD VU meter will also 
illuminate from amber to white with yellow background. The

 

C 3050 is ready for operation when the NAD VU meter is illuminated 
white with yellow background.

• 

Pressing the Power button again turns the unit back to standby 
mode. The Power LED indicator will change from green to amber 
color. The NAD VU meter will also turn off.

• 

The Power button cannot activate the C 3050 if the rear panel 
POWER switch is off.

IMPORTANT NOTES
