QUICK START

Refer to the supplied C 268 Quick Setup Guide for basic instructions 
in setting up your new NAD C 268.  The following guidelines must be 
observed when setting up your C 268. 

Before setting up or making connections, ensure that the C 268 and other 
devices to be connected to C 268 are unplugged or powered down.  

Connect your speakers to the LEFT and RIGHT speaker terminals. 
Connect the speaker cables to the corresponding speaker terminal 
connections (R +/-, L +/-) as reflected in the C 268 rear panel. Bare wire 
or loose strands from the speaker cables must not touch the rear panel 
or other speaker terminals.  

Connect the line output terminal of your external sources to the 
BALANCED and/or SINGLE-ENDED ANALOG AUDIO INPUT ports using 
applicable connectors.  

IMPORTANT NOTES

•  The blue terminals must never be connected to ground (earth).
•  Never connect the blue terminals together or to any common ground 

device.

•  Do not connect the output of this amplifier to any headphone adapter, 

speaker switch or any device that uses common ground for left and 
right channels.

Connect corresponding end of the mains power cord to the AC mains 
input of C 268 and the plug connected to a mains power source.

WARNING 

 

For optimal performance, the C 268 requires a grounded AC receptacle 
or a separate earth ground. Ensure the proper grounding of your system.

Maintain default settings of the following control switches’ 

• 

LEFT and RIGHT SELECT towards BALANCED or SINGLE-ENDED 
(both switches must be of the same setting)

• 

INPUT SELECT to FIX

• 

AUTO SENSE LEVEL to MID

Set the POWER switch at the rear panel to “ON” setting. The Standby 
LED indicator will illuminate amber. Press front panel STANDBY button 
to turn ON the C 268. The Standby LED indicator will turn from amber 
to blue. Your C 268 is now powered up!

SAVE THE PACKAGING

Please save the box and all of the packaging in which your C 268 arrived. 
Should you move or otherwise need to transport your C 268, this is by far 
the safest container in which to do so. We’ve seen too many otherwise 
perfect components damaged in transit for lack of a proper shipping 
carton, so please: Save that box!

NOTES ON INSTALLATION
• 

Place your NAD C 268 on a firm, level surface. 

• 

Avoid placing the unit in direct sunlight or near sources of heat and 
damp. 

• 

Do not place the unit on a soft surface like a carpet. 

• 

Do not place the C 268 in an enclosed position such as a bookcase 
or cabinet that may impede the air-flow through the ventilation slots. 
Allow adequate ventilation. 

• 

Make sure the unit is switched off before making any connections.

• 

The RCA sockets on your C 268 are color coded for convenience. Red 
and white are Right and Left audio respectively. Use high quality leads 
and sockets for optimum performance and reliability. 

• 

Ensure that leads and sockets are not damaged in any way and all 
sockets are firmly pushed home.

• 

Should water get into your C 268, shut off the power to the unit and 
remove the plug from the AC socket. Have the unit inspected by a 
qualified service technician before attempting to use it again.

• 

Use a dry soft cloth to clean the unit. If necessary, lightly dampen the 
cloth with soapy water. Do not use solutions containing benzol or other 
volatile agents.

DO NOT REMOVE THE COVER; THERE ARE NO USER-SERVICEABLE 
PARTS INSIDE.
