If an indoor antenna is used (either built into the set or installed separately), never allow any part of the antenna to touch the metal parts of other electrical appliances such as a lamp, TV set etc. Warning: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture. The graphic symbol of a lightning flash with an arrow point within a triangle signifies that there is dangerous voltage within the unit and it poses a hazard to anyone removing the cover to gain access to the interior of the unit. Only qualified service personnel should make any such attempt. CAUTION POWER LINES Any outdoor antenna must be located away from all power lines. The graphic symbol of an exclamation point within an equilateral triangle warns a user of the device that it is necessary to refer to the instruction manual and its warnings for proper operation of the unit. OUTDOOR ANTENNA GROUNDING If an outside antenna is connected to your tuner or tuner-preamplifier, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code, ANSI/NFPA No. 70-1984, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes and requirements for the grounding electrode. a. Use No. 10 AWG (5.3mm2) copper, No. 8 AWG (8.4mm2) aluminium, No. 17 AWG (1.0mm2) copper-clad steel or bronze wire, or larger, as a ground wire. b. Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4-6 feet (1.22 - 1.83 m) apart. c. Mount antenna discharge unit as close as possible to where lead-in enters house. d. Use jumper wire not smaller than No.6 AWG (13.3mm2) copper, or the equivalent, when a separate antenna-grounding electrode is used. see NEC Section 810-21 (j).

NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV system installer's attention to Article 820-22 of the National Electrical Code that provides guidelines for proper grounding and, in particular, specifies that the ground cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical. NAD 2 REAR PANEL CONNECTIONS 120V version only FRONT PANEL CONTROLS FIGURE 1. FIGURE 2. NAD 3 GB NAD 114 STEREO PREAMPLIFIER 3. PHONO INPUT. Plug the signal cables from your turntable into these jacks. If the cables or plugs are color-coded, refer to your turntable's instruction manual to learn which cable or plug is for the Left channel (upper jack) and which for the Right (lower jack). Be careful to insert each plug fully into the socket so that the plug's metal skirt fits tightly over the exterior of the socket. If necessary, crimp the plug's metal skirt slightly so as to obtain a tight fit with the socket. INSTRUCTIONS FOR INSTALLATION AND OPERATION Your NAD114 should be placed on a firm, level surface. Avoid placing the unit in direct sunlight, near sources of heat and damp or in poorly ventilated positions. 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 114, 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. Use a dry soft cloth to clean the unit. If necessary, lightly dampen the cloth with soapy water. Do not use solutions containing benzol or other volatile agents. 4. CD INPUT. Connect the audio signal cables from a digital Compact Disc player to these jacks. The input signal will be fed to the Volume control before reaching any active circuitry, so the preamplifier's circuits cannot be overloaded by high-level signals from the digital player. If you don't have a CD player, any other line-level signal source (such as a spare tape deck) may be connected to the CD input. REAR PANEL CONNECTIONS 1. PHONO GROUND. If your LP turntable is equipped with a grounding wire (usually a green wire terminating in a U-shaped spade lug), connect it to this terminal. Turn the thumb-nut counter-clockwise, place the spade lug under the nut, and tighten the thumb-nut clockwise to secure the lug. If the grounding wire has no spade lug, strip off 1 cm of insulation to expose the bare wire, twist the wire strands tightly together, insert the wire though the small hole in the shaft of the Ground terminal, and tighten the thumb-nut to fasten the wire in place. (Fig. 1). If you encounter a persistent low-level hum or buzz in the sound, connect a wire from the Ground terminal to a true earth-ground, i.e. a copper-plated rod driven several feet into the earth. A substitute electrical ground, such as a cold water pipe, may also prove effective. 5. VIDEO SOUND INPUT. Connect a video-related audio signal here, such as the audio output from a video cassette recorder, video disc player, TV monitor/receiver, or stereo television decoder. Alternatively, any "line-level" audio signal may be connected here, such as the playback from a spare tape deck. If you don't have a VCR player, any other line-level signal source (such as a spare tape deck) may be connected to the Video Sound input. 6. AUXILIARY INPUT Any "line-level"signal source may be connected here, such as the audio output from a spare deck or video product. For example. you could connect the audio from a stereo television set here and the audio from a stereo VCR to the Video input. 7. TUNER INPUT 2. MM/MC SELECTOR. This switch sets the input sensitivity and gain of the phono preamplifier circuit. Set it according to the output level of your phono pickup cartridge. Set the switch at MM for cartridges of the moving magnet, induced magnet, moving flux, and moving iron (variable reluctance) types, and for "high-output" movingcoil pickups, i.e. those with a rated output of 1.0 mV or greater. If your cartridge is a low-output movingcoil pickup (with a rated output of less than 1.0 mV), set the switch at MC. Here is another way to determine the preferred setting of the MM/MC switch. Begin by setting it to MM. After you have completed the installation and wiring of the system, play a record. You should obtain a satisfyingly loud volume level with VOLUME control set at 9 o'clock. If you have to turn up the VOLUME control beyond 9 o'clock to get adequately loud sound, turn the VOLUME back down and re-set the MM/MC switch to MC. NAD 4 Connect the audio signal cable from an AM/FM (or video) tuner to this pair of jacks. If you don't have a Tuner, any other line-level signal source (such as a spare tape deck) may be connected to the Tuner input. 8. TAPE 1 INPUT/OUTPUT. These jacks allow you to connect a second tape recorder of any type, and the preamplifier is wired to permit copying tapes from one recorder to the other. Connect a cable from the TAPE 1 OUT jacks of the 114 to the recorder's LINE IN jacks, and another cable from the recorder's LINE OUT jacks to the TAPE 1 IN jacks. The TAPE 1 jacks may be used for a signal-processing accessory instead of a second tape recorder. Examples of such accessories include a dynamic range processor, a dynamic noise filter, or a graphic equalizer. Connect a patch cord from the TAPE 1 OUT jacks to the processor's inputs, and another GB patch cord from processor's outputs to the TAPE 1 IN jacks. The tape connections may be used with recorders of all types: cassette, micro-cassette, open-reel, digital, etc. To make recordings, connect a stereo patch cord from the TAPE 1 OUT jacks of the 114 to the recorder's LINE IN jacks (not its microphone inputs). To play back tapes, connect a stereo patch cord from the recorder's LINE OUT jacks to the TAPE 1 IN jacks of the 114. (See Figure 2) Insertion of a plug into the PHONES socket automatically mutes the signal at the PREAMP OUTPUT jacks, silencing the loudspeakers. In order to resume listening to loudspeakers you must unplug the headphones from the PHONES socket. 3. BASS. The Bass control adjusts the relative level of the low frequencies in the sound. The electrical response of the preamplifier is flattest when the control is set in the detent at the 12 o'clock position. Rotation of the knob to the right (clockwise) increases the level of low-frequency sounds, and rotation counter-clockwise decreases their level. Adjust the Bass control to achieve the tonal balance that sounds most natural to you. At moderate rotations away from center the effect of the Bass control is subtle, because its action is confined to the lowest audible frequencies where significant energy is seldom found in recordings.
