tion or over with "High Gain" (21) switched on, it is rec-
ommended that the System Sensitivity switch is set to
the "Normal" position.
NOTE: If there are significant differences in loudness
levels between the digital sources and some or all of
the analogue sources then it is likely that the Input Gain
sensitivity for those analogue inputs hasn't been set
correctly. Before choosing the final position of the
System Sensitivity switch make sure all Input Gain lev-
els for all analogue sources have been set correctly.
Refer to section "Input Gain" of this chapter for more
information.
NOTE: The System Sensitivity switch works only on
the analogue pre-amplifier output. The switch doesn't
have any effect on the pre-amp digital output (2 on
back panel drawing).

The numbers refer to the front panel drawing unless
stated otherwise.
POWER ON / OFF (2)
Press the Power button (2) to turn on the pre- amplifi-
er. The status (Power) LED (1) glows green when the
power is on and the pre-amplifier is ready for use.
Press the Power button again to switch the pre-amplifi-
er off.
By pressing the Power button on the remote control
(1 the on remote control drawing) the pre-amplifier can
be switched to "stand-by". In this state the majority of
the pre-amplifier's circuits are powered down and
power consumption is minimal, the Status LED (1)
turns from green to red to indicate stand-by status.
Only a small section remains active, allowing the pre-
amplifier to respond to the remote control; by pressing
any button on the remote control or any button on the
front panel (apart from the Power button (2) or High
Gain (21), the pre-amplifier will power up and is ready
for normal operation once the Status LED (1) has
turned from red to green. From the stand-by mode the
pre-amplifier will revert to the last selected input, DSP
function and setting when powered up from the front
panel or by the Power button on the remote control (1
on remote control drawing).
NOTE: When using the power On with the Power
button (2) the pre-amplifier will always select the Digital
Disc input and the tone control DSP mode with DSP
switched Off, regardless of settings when it was
switched off.
INPUT SELECTOR (4 to 13)
The NAD Model 118 has 8 inputs in total. On both
the remote control and the front panel the top row of
the input selector are for analogue sources, the bottom
row is for digital sources.
Select the desired input by pressing the appropriate
button on either the remote control or front panel. The
LED in the button on the front panel will light up. In the
case where a digital input has been selected, the LED
will flash until it "locks in" on the digital source. If no
source is connected to the selected digital input or it
has been switched off, the LED will continue to flash.
NOTE: If the LED for a digital source continues to
flash whilst the source is connected and playing it may
be that there is a cable mis-match. For digital sources
use interconnects with the correct impedance (75 ).
NOTE: Some CD players mute the digital signal if the
player is in stop mode which causes the LED in the
input button of the pre-amp to flash until the CD players
starts playing back a CD.
NOTE: Switch off either one of the tape check modes
(8 & 13) in case these are engaged (the amber LED in
the Tape Check button is lit when switched on). For
more information also refer to the section below "Tape
Check 1 & 2".
TAPE CHECK 1 & TAPE CHECK 2 (8 & 13)
During recording it can be desirable to be able to
monitor the signal coming back from the recorder, par-
ticularly with analogue 3-head recorders and a few digi-
tal recorders whereby it is possible to listen to the
recorded music itself whilst making the recording. For
this purpose the NAD Model 118 is equipped with two
Tape Check inputs.
Both Tape Check inputs are looped in the few ana-
logue circuits of the NAD Model 118 and can be
engaged at any time during recording or for play-back
only. Both Tape Check buttons are switched on by
pressing either button once; the amber LED in the but-
ton lights up. To switch Tape Check off, press Tape
Check again.
The Tape Check 1 button (8) of the input selector will
monitor the signal from a recorder connected to the
analogue Tape input (7; 11 on the back panel).
The Tape Check button 2 (13) of the input selector
will monitor the (analogue) signal from a digital recorder
connected to the "Analogue from DAC" input (12 on the
back panel). Besides the digital input and output the
analogue output of the digital recorder has to be con-
nected as well. Refer also to Chapter 2, section
"Analogue source inputs and recording outputs".
NOTE: As both Tape Check inputs operate entirely in
the analogue domain, the DSP functions, including bal-
ance control, the Mono and Absolute Phase buttons do
not function on either one of the Tape Checks. The
DSP functions can be heard through either one of the
tape checks only during recording, provided "Process
to tape" (14) and "DSP In" (15) have been selected, but
changes made using the DSP functions will affect the
recording.
NOTE: Tape Check 1 and Tape Check 2 work entire-
ly in the few analogue circuits of the Model 118 only.
When using the Model 118 with an external DAC the
Tape Check buttons do not function, the amber LEDs
will light up when either Tape Check button is pressed
however.

VOLUME CONTROL

To increase volume turn the volume control (22)
clockwise; to decrease volume turn the control counter
clockwise.
It is also possible to change volume with the remote
control. To increase the volume by remote press vol-
ume Up; to decrease volume press Volume Down (sec-
tion 12 of remote control drawing).
The bar in the display area (26) lights up to show the
setting of the volume control. As the volume is
