NAD C 388 Manuel Du Propriétaire

•  Connect to the corresponding optical or coaxial digital output of 

sources such as CD or BD/DVD players, digital cable box, digital 

tuners and other applicable components. 

PHONO: Input for a Moving Magnet (MM) phono cartridge. Connect 

the twin RCA lead from your turntable to this input if you are using a 

Moving Magnet cartridge.

LINE1, LINE 2: Input for line level sources such as CD player, tuner or 

any compatible devices. Use a twin RCA-to-RCA lead to connect the 

source device’s left and right “Audio Output” to this input.

•  These output terminals have dual function. They are used either as 

PRE-OUT or SUBWOOFER terminals.

•  The C 388 and associated external devices must be turned OFF 

always before connecting or disconnecting anything to the PRE-

OUT/SUBW sockets.

•  The PRE OUT/SUBW sockets make it possible to use the C 388 as a 

full range preamplifier to an external power amplifier. 

•  Use dual RCA cable to connect PRE-OUT/SUBW to the 

corresponding analog audio input of compatible devices such as 

amplifiers, receivers or other applicable devices.

•  PRE-OUT/SUBW will be affected by the C 388’s volume control 

settings. Turn the VOLUME control to adjust the output level of the 

PRE OUT/SUBW sockets. 

•  Use a dual RCA cable to connect PRE OUT/SUBW to the low level 

input of a powered subwoofer.

•  Low frequency information up to 200Hz is sent to the connected 

subwoofer via PRE OUT/SUBW.

•  These mini-jacks accept and output remote-controlled codes in 

electrical format, using industry-standard protocols, for use with 

“IR-repeater” and multi-room systems and related technologies. 

•  All NAD products with IR IN/IR OUT features are fully compatible 

with the C 388. For non-NAD models, please check with your other 

product’s service specialists with respect to their compatibility to 

the C 388’s IR features.

•  This input is connected to the output of an IR (infrared) repeater 

(Xantech or similar) or the IR output of another compatible device 

to allow control of the C 388 from a remote location.

•  Connect IR OUT to the IR IN jack of a compatible device.
•  Command and control the linked compatible device by directing its 

own remote control to C 388’s infrared receiver.

•  The +12V TRIGGER OUT is used for controlling external equipment 

equipped with a +12V trigger input. 

•  Connect this +12V TRIGGER OUT to the other equipment’s 

corresponding +12V DC input jack using a mono cable with 3.5mm 

male plug. 

•  This output will be 12V when the C 388 is ON and 0V when it is 

either OFF or in standby mode. 

•  With this input triggered by a 12V DC supply, the C 388 can be 

switched ON remotely from standby mode by compatible devices 

such as amplifiers, preamplifiers, receivers, etc. If the 12V DC supply 

is cut off, the C 388 will return to standby mode.

•  Connect this +12V Trigger input to the remote device’s 

corresponding +12V DC output jack using a mono cable with 

3.5mm male plug. The controlling device must be equipped with a 

+12V trigger output to use this feature.
