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.

CAUTION

POWER LINES

Any outdoor antenna must be located away from all power lines.

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 volt-

age 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 dis-

charge 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 equiva-

lent, when a separate antenna-grounding electrode is used. see NEC Section

810-21 (j).

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 posi-

tions.

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-ser-

viceable 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.

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 termi-

nal to a true earth-ground, i.e. a copper-plated rod

driven several feet into the earth. A substitute electri-

cal ground, such as a cold water pipe, may also

prove effective.

2. MM/MC SELECTOR.

This switch sets the input sensitivity and gain of the

phono preamplifier circuit. Set it according to the out-

put level of your phono pickup cartridge. Set the

switch at MM for cartridges of the moving magnet,

induced magnet, moving flux, and moving iron (vari-

able reluctance) types, and for "high-output" moving-

coil pickups, i.e. those with a rated output of 1.0 mV

or greater. If your cartridge is a low-output moving-

coil pickup (with a rated output of less than 1.0 mV),

set the switch at MC.

Here is another way to determine the preferred set-

ting 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.

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.

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.

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 tele-

vision 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

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 sig-

nal source (such as a spare tape deck) may be con-

nected 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-pro-

cessing 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

NAD

NAD 114 STEREO PREAMPLIFIER

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, digi-

tal, 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)

9. TAPE 2 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 2 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 2 IN jacks.

10. PRE OUT 1 & 2.

Two pairs of RCA phono preamp output jacks are

provided for convenience. This is the normal output

from the preamplifier. Connect a stereo signal cable

from these jacks to the main input jacks on your

power amplifier.

The preamp has a low output impedance (220

ohms). It can drive several amplifiers connected in

parallel, and it can be used with long signal cables in

order to drive power amplifiers that are located near

the speakers (or "powered" speakers having built-in

power amplifiers).

If you have a special loudspeaker equalizer or

another signal processor that should be installed in

the signal path after the volume control, connect a

cable from either pair of the PRE OUT jacks to the

input of the processor, and a second cable from the

output of the processor to the main input of your

power amplifier.

11. AC LINE CORD.

After you complete all connections to the preampli-

fier, plug the AC line cord into a "live" AC socket.

FRONT PANEL CONTROLS

1. POWER

Press to switch on the power to the 114 (and to any

other products plugged into the SWITCHED conve-

nience outlets on the rear panel of 120V versions) .

To switch the power off, press the button again.

2. PHONES

Plug stereo headphones in here. The circuit will

provide proper drive signals for all conventional

stereo headphones regardless of their impedance,

with just one exception: electrostatic headphones

usually are supplied with an adapter unit which must

be connected directly to the speaker terminals on

your power amplifier.

Insertion of a plug into the PHONES socket auto-

matically mutes the signal at the PREAMP OUTPUT

jacks, silencing the loudspeakers. In order to resume

listening to loudspeakers you must unplug the head-

phones 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 con-

trol 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 sig-

nificant energy is seldom found in recordings. Only at

large rotations away from center is there a substantial

boost or cut at the mid-bass frequencies that are

common in music.

When the TONE DEFEAT button is engaged, the

Bass and treble circuits are bypassed.

4. TONE DEFEAT.

When this button is pressed the Bass and Treble

circuits are bypassed, restoring precisely flat frequen-

cy response. This provides a convenient way to eval-

uate settings of the Bass and Treble controls. By

adjusting the tone controls and then switching them in

and out of the signal path, you can easily evaluate

their effect on the musical sound.

5. TREBLE.

The Treble control adjusts the relative level of the

high frequencies in the sound. The response of the

preamplifier is flattest when the control is set in the

detent at the 12 o'clock position. Rotation of the

Treble control to the right (clockwise) increases the

level of high-frequency sounds, and rotation counter-

clockwise decreases their level. Adjust the Treble

control to achieve the tonal balance that sounds most

natural to you.

Boosting the Treble increases the brilliance and

clarity of details in the sound, but also makes any

noise more prominent. Turning down the Treble

makes the sound mellower while suppressing hiss

and record surface noise; but too much Treble roll-off

will make the sound dull.

6. BALANCE.

The Balance control adjusts the relative levels of

the left and right channels. It has no effect on record-

ings being made. A detent at the 12 o'clock position

marks the point of equal balance. Rotation of the

Balance control to the right (clockwise) decreases the

level of the left channel so that only the right channel

is heard, thus shifting the sonic image to the right.

Rotation of the control to the left shifts the sonic

image toward the left speaker.
