User manual NAD S300

[. . . ] Do not use this unit near water; for example, near a bath tub, washbowl, kitchen sink, laundry tub, in a wet basement or near a swimming pool. The unit should be installed so that its location or position does not interfere with its proper ventilation. For example, it should not be situated on a bed, sofa, rug or similar surface that may block the ventilation openings; or placed in a built-in installation, such as a bookcase or cabinet, that may impede the flow of air through its ventilation openings. The unit should be situated from heat sources such as radiators, heat registers, stoves or other devices (including amplifiers) that produce heat. [. . . ] 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. 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. 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. 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. The signal "hot" and return currents are both carried on inner conductors. The separate cable shield, connected to the amplifier chassis at both ends, protects the audio signal from all forms of interference and power-supply noise. Input for the audio signal from a stereo VCR (or stereo TV/Satellite/Cable receiver) or other line-level audio source. Using twin RCA-to-RCA leads, connect to the left and right `Audio Outputs' of the unit to these inputs. Input for additional line level input signals or a CD player with no balanced output. Use a twin RCA-to-RCA lead to connect the auxiliary unit's left and right `Audio Outputs' to these inputs. In the event of radio hum or radio interference, this terminal can be connected to a `true earth' such as a copper plated rod driven several feet into the ground. Use a twin RCA-toRCA lead to connect the Tuner left and right `Audio Outputs' to these inputs. [. . . ] Two AAA (LR03) batteries should be fitted in the battery compartment of the Remote control handset. When replacing batteries, check that they have been put in the right way round, as indicated on the base of the battery compartment. please refer to previous sections of the manual for a full description of individual functions. NOTE: The remote control handset supplied is the NAD universal remote and can be used on any remote controllable NAD system. [. . . ]
