User manual NAD C272

[. . . ] Warning: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture. The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. the exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. Do not place this unit on an unstable cart, stand or tripod, bracket or table. [. . . ] The RCA sockets on your NAD C 272 are colour coded for convenience. Ensure that leads and sockets are not damaged in any way and all sockets are firmly pushed home. If the unit is not going to be used for some time, disconnect the plug from the AC socket. Should water get into your NAD C 272, 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. dO NOT REMOVE THE COVER , THERE ARE NO USER-SERVICEABLE PARTS INSIDE. If necessary, lightly dampen the cloth with soapy water. Do not use solutions containing benzol or other volatile agents. The Fixed Inputs take the input signal straight to the power amplifier's circuitry. This set of inputs is normally used in a system with only one power amplifier or multiple but identical power amplifiers. Refer also to section "Variable In" in this chapter for more information. Connect the output from a pre-amplifier or processor, such as a surround-sound decoder, to this set of inputs. Use a twin RCA-toRCA lead to connect to the left and right `Audio Output' of the pre-amp or processor to the Fixed-In sockets. NOTES: Always turn the C 272 and other components in the system off before connecting or It is disconnecting anything to the "Fixed In" or Variable In" sockets. When using the Fixed In sockets, make sure the "Input Select" switch (No. The Input Level control works in combination with "Variable In" (No. With the control the volume to the power amplifier can be adjusted from zero (counter clock-wise) to maximum (turned up all the way clock-wise). Refer also to section "Variable In" in this chapter for more information. NOTE: Always turn the C 272 and other components in the system off before connecting or disconnecting anything to the "Fixed In" or Variable In" sockets. Set to "FIX" for use with "Fixed In" and to "VAR" for use with "Variable In". Refer also to section "Variable In" in this chapter for more information. Use the Speakers A connectors for the `main' speakers and use the Speakers B connectors for a second pair, for example, extension speakers located in another room. [. . . ] Upon switching Power on, the indicator will light up red and after a short pause turn to green to indicate the amplifier is ready for use. In cases of serious abuse of the amplifier, such as overheating, excessively low loudspeaker impedance, short circuit, etc. the amplifier will engage its Protection circuitry. The indicator will light up red and the sound will be muted. [. . . ]
