User manual NAD S400

[. . . ] 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. [. . . ] Before connecting the cable to a live wall socket, ensure that it is firmly connected to the NAD S400's AC Mains input socket first. Always disconnect the AC mains cable plug from the live wall socket first before disconnecting the cable from the S400 Mains input socket. The blue LED above the POWER button lights up briefly when ON/OFF is activated, but it goes out again immediately. The blue LED lights up permanently only to indicate stand-by if the unit is turned off from an NAD system remote control with STANDBY button. If this option is used, the S400 may be switched on again by pressing the STANDBY button of the system remote, or by pressing and releasing the POWER button on the front of the S400 to switch it off, and then press it again to switch it on. Please note that the remote control which comes with the S400 does not feature a STANDBY button. This information is retained even if the unit is switched off completely or unplugged. NOTE: When switching power On, the S400 will go back to the station last tuned to before the unit was turned off. This will allow you to make timer recordings using an external timer and recorder. The S400 is equipped with two antenna connectors to allow you to connect simultaneously to for example a cable network and an outdoor aerial. a ribbon wire FM antenna is included in order to permit reception even if no outdoor antenna or cable is available. It should be connected to one of the FM connectors at the rear of the unit using the `balun' adapter supplied. Experiment with placement of the indoor antenna to find the position that gives the best signal strength and lowest background noise. An inadequate FM signal normally results in high levels of hiss, especially in stereo, and interference from external electrical sources. In areas of poor FM reception, the tuner performance can be improved by using an externally mounted FM antenna. A qualified aerial installer will be able to advise and fit a recommended aerial for your reception conditions. Switches between Stereo mode with Muting (Mute) on and Mono mode with Muting off. As these will always be too weak for stereo reception, Mono is activated simultaneously. The first press of the button shows Mute On or Off as well as Stereo or Mono in the display panel. Five seconds to turn Muting off (or on) and at the same time switch from stereo to mono. High Blend is used for stations that are too remote or weak to permit noise-free reception in stereo. In order to reduce noise and hiss, this feature "blends" the stereo channels into mono within a narrow audio frequency band, thereby reducing hiss considerably while still maintaining good stereo separation. [. . . ] The RDS indicator lights up when a station broadcasting RDS data is received. The SEARCH indicator lights up (in 120V version only) when the S400 is in Search mode. The STEREO indicator lights up when the S400 receives a stereo broadcast. The CENTRE TUNE indicator lights up when the S400 is tuned to the exact frequency of the transmitter. [. . . ]
