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
