User manual NAD S300

[. . . ] 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. [. . . ] CAUTION: To prevent a fire or shock hazard, do not permit liquid or moisture to enter the amplifier. If liquid is accidentally spilled on it, immediately shut off the power and unplug the AC Mains cable. Have the unit inspected by a qualified service technician before attempting to use it again. Switch the unit off before making any connections. The RCA connectors on your S300 are colour coded for convenience. Red and white are Right and Left audio respectively, and yellow for NAD-Link. always use high quality leads and connectors for optimum performance and reliability. Ensure that leads and connectors are not damaged in any way and all connectors are firmly pushed home. If the unit is not going to be used for some time, disconnect the plug from the AC socket. Do not remove the cover, there are no user-serviceable parts inside. If necessary, lightly dampened the cloth with soapy water. Do not use solutions containing benzol or other volatile agents. In case you do not wish to use a CD player featuring balanced outputs, use the AUX input for RCA connectors instead. With a conventional (unbalanced) connection, audio signal current flows from the CD player to the amplifier via the cable's centre conductor. To complete the circuit, audio signal current flows back to the CD player ground via the cable's outer conductor. the outer conductor also serves as the cable's shield. When two audio components are connected together, power-supply noise and "leakage" hum may also flow on the cable shields, combining with the return audio current. The resulting distortion and noise may depend on the orientation of AC power plugs in their sockets. Designers of some audiophile cables combat this contamination by leaving the shield unconnected at one end. Since the shield is grounded at only one end, the performance of such a cable may depend on the direction of its connection, i. Whether the shield is grounded at the CD player or at the amplifier. a three-wire balanced connection avoids all of these uncertainties. [. . . ] A single NAD-Link connection from a hi-fi system in a second room will allow remote control of Multi Room systems. Connect the right speaker to the terminals market `R +' and `R-' ensuring that the `R+' is connected to the `+' terminal on your loudspeaker and the `R-' is connected to the loudspeaker's `-' terminal. connect the terminals marked `L+' and `L-' to the left speaker in the same way. The high current binding post terminals can be used as a screw terminal for cables terminating in spade or pin connectors or for cables with bare wire ends. [. . . ]
