OUTDOOR ANTENNA GROUNDING

If an outside antenna is connected to your tuner or tunerpreamplifier, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 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 leadin 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). EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL CODE INSTRUCTIONS CONTAINED IN ARTICLE 810 - RADIO AND TELEVISION EQUIPMENT. 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 NAD S100 preamplifier may be fitted with a dedicated Phono Module to allow for direct connection of phono Moving Magnet (MM) or Moving Coil (MC) cartridges.

NOTES ON INSTALLATION

Your S100 should be placed on a firm, level surface. Avoid placing the unit in direct sunlight or near sources of heat and damp. Allow adequate ventilation. Do not place the unit on a soft surface like a carpet. Do not place it in an enclosed position such as a bookcase or cabinet that may impede the airflow through the ventilation slots. Switch the unit and all ancillary equipment off before making any connections. The RCA connectors on your S100 are colour coded for convenience. Red and white are Right and Left audio respectively, and yellow for NAD-Link. The S100 comes with RCA leads for basic connections. Where additional leads are required, 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. Should water get into your S100, 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.

Depending on your version of the NAD S100 preamplifier, it may already be fitted with the dedicated S100 Phono Module. The S100 Phono Module can be retro-fitted by your dealer who can also set the parameters (such as MM or MC, MC cartridge impedance) of the Phono Module to suit your specific turntable and cartridge combination. Without the S100 Phono Module: Without the module installed, the PHONO/AUX2 input provides an additional line-level input such as an additional CD player, MD player, etc. Use a twin RCA-to-RCA lead to connect the auxiliary unit’s left and right ‘Audio Outputs’ to these inputs. NOTE: Without the Phono Module only a very faint sound will be heard if a turntable fitted with an MM or MC cartridge is connected. Consult your dealer to have the optional Phono Module fitted. With the S100 Phono Module: Ensure that your dealer has chosen the correct settings inside the Phono Module (MM or MC, cartridge impedance) to suit your specific turntable and cartridge combination. Connect the twin RCA lead from your turntable, observing that the left and right channels are connected correctly.

3. PHONO GROUND CONNECTOR

Apart from the twin RCA lead, most turntables also include a single wire earth lead. Connect this to the S100 chassis PHONO GROUND connector.

Input for a CD or other line-level signal source. Use a twin RCA-to-RCA lead to connect the CD player left and right ‘Audio Outputs’ to these inputs. The S100 only accepts analogue signals from your CD player. The S100 comes supplied with a separate AC Mains cable. Before connecting the cable to a live wall socket ensure that it is firmly connected to the NAD S100’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 S100 Mains input socket. Voltage conversion: A notice printed on the rear indicates the AC power-line voltage that the preamplifier requires. However, every model S100 amplifier has a “universal” power supply that can be modified easily for operation in other countries. If you wish to transport your S100 to a nation that employs a different power-line voltage, an authorised NAD dealer or service agency can convert it for such use.

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. NOTE: These are audio inputs only.

Input for additional line level input signals such as another CD player. Use a twin RCA-to-RCA lead to connect the auxiliary unit’s left and right ‘Audio Outputs’ to these inputs.

Input for a Tuner or other line-level signal source. Use a twin RCA-toRCA lead to connect the Tuner left and right ‘Audio Outputs’ to these inputs.

Connections for analogue recording and playback to a secondary audio tape recorder of any type. Using twin RCA-to-RCA leads, connect to the left and right ‘Audio Outputs’ of the tape machine to the TAPE 2 IN connectors for playback. Connect the left and right ‘Audio Inputs’ of the tape machine to the TAPE 2 OUT connectors for recording.

Connections for analogue recording and playback to an audio tape recorder of any type. Using twin RCA-to-RCA leads, connect to the left and right ‘Audio Outputs’ of the tape machine to the TAPE 1 IN connectors for playback and tape monitoring. Connect the left and right ‘Audio Inputs’ of the tape machine to the TAPE 1 OUT connectors for recording.

10. PRE 1, PRE 2 OUT (UNBALANCED)

Connections for an external power amplifier, processor or active speakers. Use twin RCA-to-RCA leads to connect to the left and right ‘Audio Inputs’ of the power amplifier, processor or active speakers to the PRE 1 or PRE 2 OUT connectors. The PRE 1 and PRE 2 OUT sockets carry the same signal and may be used simultaneously for e.g. bi-amping. The PREOUT output signal is controlled by the S100’s volume and balance control settings. These sockets provide connections to amplifiers, active speakers and processors requiring an unbalanced RCA connections.

Connections to an external power amplifier or processor that uses balanced XLR connectors. These are fully balanced XLR outputs, suitable to drive most balanced hi-fi and professional amplifiers. The wiring standard used for these connectors is: Pin 1 Chassis Earth (Ground) Pin 2 Hot (Live ) Pin 3 Signal Ground (Return)

12. NAD-LINK IN, OUT

The NAD-Link connector is used to pass commands from the remote control to and from other units fitted with NAD-Link connectors. This allows centralised control of a complete system or gives system control from more than one room. To function with other units, connect the S100’s NAD-Link OUT to the NAD-Link IN on the other unit. NAD-Link connectors can be daisy-chained, IN to OUT, so that a whole system can be controlled from the remote control facilities of one unit. A single NAD-Link connection from a hi-fi system in a second room will allow remote control of Multi Room systems.

FRONT PANEL CONTROLS

Pressing the POWER button turns the unit On and after a few seconds, the Power indicator LED will extinguish. Pressing the POWER button again will turn the preamplifier Off. When the S100 is switched On, pressing the Standby button on the remote handset will put the S100 into Standby mode and the Power indicator will light up blue. The blue Standby indicator shows that power is being supplied to the S100, but the system is currently in the Standby mode. CAUTION: When in Standby mode, power is still supplied to your S100. You should switch it Off using the front panel POWER button when it is not being used for long periods of time.

Sensor for receiving the infrared signals from your remote control handset. The LED above the sensor flashes to confirm infrared reception.

These buttons select the active input to the S100 and the signal sent to the TAPE outputs, the PRE 1 & PRE 2 OUT and XLR output sockets. LEDs over each button will indicate which input is currently selected. PHONO/AUX 2 Selects the source connected to the PHONO/AUX 2 input. With the optional S100 Phono Module installed, a turntable Phono with either an MM or MC cartridge can be connected. Without the optional Phono Module installed you can use this input for any line-level source. CD Selects the CD (or other line-level source) connected to the CD sockets as the active input. VIDEO Selects the VCR (or stereo TV/Satellite/Cable receiver) connected to the VCR sockets as the active input. AUX 1 Selects a line-level source connected to the AUX sockets as the active input. TUNER Selects the tuner (or other line-level source) connected to the Tuner sockets as the active input. TAPE 2 Selects Tape 2 as the active input. TAPE 1 MONITOR Selects the output from a tape recorder when playing back tapes or monitoring recordings being made through the TAPE 1 sockets. Press the TAPE 1 MONITOR button once to select it and again to return to the normal input selection. TAPE 1 MONITOR is a tape monitor function which does not override the current input selection. For example, if CD is the active input when TAPE 1 MONITOR is selected, then the CD signal will continue to be selected and sent to both the TAPE 1, and TAPE 2 OUTPUT sockets, but it is the sound from the recorder connected to TAPE 1 that will be heard on the loudspeakers. To show which input is active in when in tape monitor mode, its indicator light will stay lit.

When any source is selected, its signal is also fed directly to any tape machine connected to the TAPE 1 or TAPE 2 OUTPUTS for recording.

TAPE TO TAPE COPYING

You can copy between two tape machines connected to your S100. Put the source tape in the recorder connected to TAPE 2 and the blank tape into the recorder connected to TAPE 1. By selecting TAPE 2 Input you can now record from TAPE 2 to TAPE 1 and monitor the signal coming from the source tape. Also you can use TAPE 1 as the source and copy to TAPE 2 but TAPE 1 MONITOR Input has to be selected for the duration of the recording. CAUTION: WHEN TAPE 2 IS SELECTED, ONLY ONE TAPE MACHINE SHOULD BE SET IN RECORD MODE. IF BOTH ARE SET IN RECORD MODE, WITH TAPE 2 SELECTED, A FEEDBACK LOOP RESULTS WHICH MAY CAUSE A LOUD “WHISTLE” OR “HOWL” , POTENTIALLY DAMAGING YOUR AMPLIFIER OR LOUDSPEAKERS.

The VOLUME control adjusts the overall loudness of the signals being fed to the loudspeakers. It is motor driven and can be adjusted from the remote control handset. The VOLUME control does not affect recordings made using the Tape outputs. REMOTE CONTROL The Remote Control handset handles all the key functions of the S100 and has additional controls to remotely operate NAD Tuners, Cassette and CD players. Alkaline batteries are recommended for maximum operating life. Two AAA (LR03) batteries should be fitted in the battery compartment at the rear of the Remote Control. 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.
