The C 352 is the latest in NAD’s range of
affordably priced, yet very high performance
Integrated Amplifiers. Building on the strengths
of our highly acclaimed C 350 (Winner of the
2002 Diapson d’Or), the C352 boasts many
upgrades and refinements. Immediately
noticeable is the new cosmetic appearance
and more robust all metal construction of
the chassis, along with the improved remote
control handset. Inside, we’ve upgraded
the Pure Class A preamp and driver stage
modules using the latest high performance
semiconductors. The power supply has also
received a complete upgrade, with the larger
custom wound toroidal transformer and
105C smoothing capacitors contributing to
a 25% increase in output power, to 80 watts
continuous. An improved tone control circuit
and revised PCB layout has reduced distortion
and noise to unprecedented levels. Taken
together, these improvements mark a sharp
upturn in performance that simply must be
heard, to be fully appreciated!
Features:
The C 352 is fully remote controlled and comes supplied
with the all-new NAD SR 5 system remote control. The
remote control features an ergonomic form, with large
buttons that are differentiated by shape and position, to
make operation intuitive and enjoyable. The SR 5 will also
operate many other NAD products such as CD players,
tuners, etc.
Flexibility is another NAD strong point. The C 352 has
7 line inputs (including 2 tape in/outputs with dubbing
facility) and the pre-amplifier section can be separated
from the power amplifier for easy upgrades or adding
ancillary equipment. Thus, the C3 52 can be expanded
to meet future system needs. The C3 52 sports 2 preamp outputs: Many systems benefit from the use of
multiple power amplifiers for “Bi-Amping” (using separate
power amplifiers to drive the bass and treble section of a
loudspeaker). With the second Preout 2 facility an extra
power amplifier, such as NAD’s C 270, which has identical
amplification factor (gain) as the C 352’s power amp
section - is easily connected.
This output can also be used to connect a powered
subwoofer, an increasingly popular option.
For remote on/off switching of ancillary components in
a system, such as power amplifiers or active speakers,
the C 352 is equipped with a 12V trigger system. When
switching the amplifier on, the 12V trigger output is also
activated which in turn can activate a 12V-trigger input and
switch on the remote devices. Besides the 12V trigger,
the C 352 also has an AC switched outlet (North American
version only) so you can easily switch your entire system
on or off with the remote control or from the front panel.
It is fashionable to omit tone controls nowadays: However,
provided that the tone controls are properly designed,
they can be really useful tools in making improvements
to the overall sound. The C 352 tone controls only work
at the frequency extremes leaving the critical mid-band
essentially unaltered. The tone control circuits can be
completely by passed by using the tone defeat switch. The
C 352 also incorporates NAD’s acclaimed switchable “Soft
Clipping” circuit, which significantly reduces the risk of damage to
loudspeakers due to prolonged high power operation.
Design: PowerDrive
The C 352 also benefits from NAD’s proprietary PowerDrive
circuit topology, now well established and used throughout the
NAD product range notably, in the highly reviewed models such
as the C 320BEE and C 370. The PowerDrive topology allows
the C 352 to deliver maximum performance under virtually any
circumstance, independent of the loudspeakers it is driving. The
circuitry automatically senses the impedance characteristics of the
loudspeaker and will then adjust its power supply settings to best
cope with that specific load.
PowerDrive topology is a practical approach to enable an amplifier
to easily deal with musical dynamics and difficult speaker loads.
Thus we have the highly desirable characteristics of high dynamic
power and low impedance drive capability in one affordable
package.
NAD also takes a stand against the meaningless “brochure power”
touted by many of our competitors by offering Full Disclosure
power specs. We specify minimum continuous power, across the
entire audible range of frequencies, at rated distortion, for both 8
and 4 Ohms with all channels driven simultaneously. Perhaps even
more importantly, we also specify Dynamic Power at 8, 4, and even
2 Ohms, which better describes the way the amplifier will perform
in the real world, with musical signals and reactive loudspeaker
loads. But even the most carefully reported specs cannot fully
describe the sonic performance of an amplifier.
Only your own ears can finally judge our achievement. We urge you
to listen and compare NAD to other products in its price range, and
even higher. We don’t think you’ll find anything that comes close
to offering the C 352’s overall musical satisfaction, well-rounded
performance, and stellar value for money.

REAR PANEL CONNECTIONS (FIGURE 1)
1. IR IN, OUT
The IR IN/OUT connector is used to pass commands from other units
fitted with IR IN/OUT connectors. This allows centralized control of a
complete system, and also allows some of the basic functions of other
NAD components (such as a tuner, CD player or cassette-deck) also
equipped with IR IN/OUT to be controlled with the amplifier's remote
control. To function with such other units, connect the C 352's IR OUT
to the IR IN on the other unit. The IR connectors can be daisy-chained,
IN to OUT, so that a whole system can be controlled from the remote
control facilities of one unit.
SVENSKA
NOTES: It is advisable not to connect IR IN/OUT if these units that have
their own built-in remote control command receiver and are positioned
together, in direct view from the remote control handset. If you are
unsure, try operating the products without IR IN/OUT first; If the unit
responds to the remote control command, it will not be necessary to
connect IR IN/OUT. Never loop the last unit back to the first NAD unit in
the IR IN/OUT chain. Unplug all units from the mains before connecting
or disconnecting IR IN/OUT.
2. DISC INPUT
Input for additional line level input signals such as CD, Mini Disc player
or the output signal from a step-up amplifier for a turntable. Use a twin
RCA-to-RCA lead to connect the auxiliary unit's left and right 'Audio
Outputs' to this input.

3. CD INPUT
Input for a CD or other line-level signal source. Use a twin RCA-to-RCA
lead to connect the CD player's left and right 'Audio Outputs' to this
input. The NAD C 352 only accepts analogue signals from your CD player.
4. VIDEO INPUT
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 Out' of the unit to these inputs.
Note: These are audio inputs only.
5. AUX INPUT

Use a twin RCA-to-RCA lead to connect the auxiliary unit's left and right
'Audio Outputs' to this input.
6. TUNER INPUT
Input for a Tuner or other line-level signal source. Use a twin RCA-to-RCA
lead to connect the Tuner left and right 'Audio Outputs' to this input.
7. TAPE 2 IN, OUT
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 Output' of the tape machine to the TAPE 2 IN sockets
for playback and tape monitoring. Connect the left and right 'Audio
Input' of the tape machine to the TAPE 2 OUT sockets for recording.
8. TAPE 1 IN, OUT
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 Output' of the tape machine to the TAPE 1 IN sockets
for playback and tape monitoring. Connect the left and right 'Audio
Input' of the tape machine to the TAPE 1 OUT sockets for recording.
9. PRE OUT 1
In normal use the PRE OUT 1 is connected to the Main-In sockets (No. 9)
with the links supplied. The NAD C 352 allows for the connection of
multiple power amplifiers. If you are using a single, external stereo
power amplifier, disconnect the links to the Main-In sockets. The
C 352's internal power amplifier is now disconnected. Use a twin RCAto-RCA lead to connect to the left and right ‘Audio Input’ of the Power
amp to the PRE OUT 1 sockets.
10. PRE OUT 2
Connections to an external power amplifier or processor, such as a
surround-sound decoder. In normal use these should be connected to
the Main-In sockets (No. 11) with the links supplied. To connect your
NAD C 352 to external processor or amplifier sections first remove these
links. Use a twin RCA-to-RCA lead to connect to the left and right
‘Audio Input’ of the Power amp or processor to the Pre Out 2 sockets.
NOTE: The Pre-Out 2 output signal will be affected by the NAD C 352’s
volume and tone control settings. Always turn the amplifier off before
connecting or disconnecting anything to the Pre-Out 2 and Main-In
sockets.
BARE WIRES AND PIN CONNECTORS
Bare wires and pin sockets should be inserted into the hole in the shaft
of the terminal. Unscrew the speaker terminal’s plastic bushing until the
hole in the screw shaft is revealed. Insert the pin or bare cable end into
the hole and secure the cable by tightening down the terminal’s bushing.
Ensure bare wire from the speaker cables does not touch the back panel
or another socket. Ensure that there is only 1/2” (1cm) of bare cable or
pin and no loose strands of speakers wire.
13. SOFT CLIPPING™
When an amplifier is driven beyond its specified power output, a hard,
distorted sound can be heard on very loud sounds. This is caused by the
amplifier cutting off or 'hard clipping' the peaks of sound that it was not
designed to reproduce. The NAD Soft Clipping™ circuit gently limits the
output of the system to minimise audible distortion if the amplifier is
overdriven.
If your listening involves moderate power levels you may leave the Soft
Clipping™ switch to Off. If you are likely to play at high levels, that could
stretch the amplifier's power capability, then switch Soft Clipping On.
The Soft Clipping™ indicator on the front panel will illuminate when the
amplifier is in Soft Clipping mode.
14. 12V TRIGGER OUT
This output allows to remotely switch on or off ancillary equipment such
as a tuner, power amplifier, etc. which are also equipped with a 12V
trigger input. This can also be an AC outlet power strip equipped with
a 12V trigger input. The 12V trigger output is activated whenever the
unit is switched to normal operational mode from Stand-by or Off.
15. IEC AC MAINS (POWER) INPUT
The C 352 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 C 352'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 C 352 Mains input socket.
SWITCHED AC OUTLET

Press the ON button to switch the unit from Stand-by to the operating
mode; The Stand-by indicator (No. 2) will turn from amber to red, then
to green after a short pause and the indicator for the last selected source
will light up. Press the OFF button to switch the unit to the Stand-by
mode: The Stand-by indicator (fig. 2; No. 2) will light up amber.
NOTE: In Stand-by mode the C 352 uses very little power. However, it
is recommended that you switch the unit totally off if it is not going to
be used for more than a couple of days. Switch off completely by
pressing the POWER button on the front panel (No. 1), all lights will
extinguish.
For switching Stand-by/Power On of an external component through
the C 352, connect the12V-trigger output of the C 352 to the remote
component's DC input jack. The plug required is a standard 3.5mm
Mini-Jack plug ("mono"): The tip is the live or + connection, the shaft
of the input jack is the 12V-trigger - or ground connection.

12. SPEAKERS
Speaker terminals for speakers with an impedance of 4 ohms or more.
Connect the right speaker to the terminals market ‘R +’ and ‘R-’
ensuring that the ‘R+’ is connected to the ‘+’ terminal on your
loudspeaker and the ‘R-’ is connected to the loudspeaker’s ‘-’ terminal.
Connect the terminals marked ‘L+’ and ‘L-’ to the left speaker in the
same way. Always use heavy duty (16 gauge; 1.5mm, or thicker)
stranded wire to connect loudspeakers to your NAD C 352. The highcurrent binding post terminals can be used as a screw terminal for cables
terminating in spade or pin sockets or for cables with bare wire ends.
Failure to observe the above may result in damage to the C 352 or any
ancillary components attached to it. If in doubt over the connections,
installation and operation of the 12V trigger output consult your NAD dealer.
DEUTSCH
NOTE: always turn the amplifier off before connecting or disconnecting
anything to the Pre-Out and Main-In sockets.
NOTES: Check the specifications of the Trigger input terminal on the
other components to ensure these are compatible with the C 352's 12Vtrigger output. NAD components equipped with 12V input triggers are
fully compatible with the C 352's 12V output trigger. The C 352's 12Vtrigger output voltage is 12V DC. The total maximum current must not
exceed 100mA. Typically, NAD 12V input triggers draw less than 10mA
of current. Before making any connections to any 12V trigger input or
output, make sure all components are disconnected from the AC mains.
ESPAÑOL
11. MAIN IN
Connections to an external pre-amplifier or processor, such as a
surround-sound decoder. In normal use these should be connected to
the Pre-Out 2 sockets (No. 10) with the links supplied. To connect your
NAD C 352 to external processor or preamplifier first remove these links.
Use a twin RCA-to-RCA lead to connect to the left and right ‘Audio
Output’ of the pre-amp or processor to the Main-In sockets.

2. POWER / STAND-BY / PROTECTION INDICATOR
Upon switching Power on, the indicator will light up amber in standby
state. While one of the input select buttons is pressed, the LED will turn
red for a moment, then turn green for ON state. In cases of serious
abuse of the amplifier, such as overheating, excessively low loudspeaker
impedance, short circuit, etc. the amplifier will engage its Protection
circuitry, the indicator will light up red and the sound will be muted. In
such a case, turn the amplifier off, wait for it to cool down and/or check
the speaker connections, making sure the overall loudspeaker
impedance doesn’t go below 4 ohms. Once the cause for the protection
circuitry to engage has been removed, switch the amplifier On again.

3. HEADPHONE SOCKET
A 1/4” stereo jack socket is supplied for headphone listening and will
work with conventional headphones of any impedance. Inserting a
headphone jack into this socket automatically switches off the
loudspeakers. The volume, tone and balance controls are operative for
headphone listening. Use a suitable adapter to connect headphones
with other types of sockets, such as 3.5mm stereo ‘personal stereo’
jack plugs.
NOTE: Make certain that the volume control is turned to minimum (fully
counter-clockwise) before connecting or disconnecting headphones.
Listening at high levels can damage your hearing.

4. INFRA-RED REMOTE CONTROL COMMAND RECEIVER
The infrared sensor, located behind this circular window, receives
commands from the remote control. There must be a clear line-of-sight
path from the remote control to this window; if that path is obstructed,
the remote control may not work.
PORTUGUÊS
NOTES: When a command from the remote control is received, the
Stand-by/protection indicator will blink. Note that the indicator may also
blink when receiving commands not necessarily for the C 352 but for
other components in the system.
Direct sunlight, very bright or fluorescent ambient lighting may affect
the operating range and angle for the remote control handset.
5. INPUT SELECTORS
These buttons select the active input to the NAD C 352 and the signal
sent to the loudspeakers, the Tape outputs and the Pre-Out sockets. The
buttons on the remote control handset duplicate these buttons, with
the exception of the tuner input; see below. Green indicators just above
each button show which input is currently selected.
DISC Selects a line-level source connected to the DISC sockets as the
active input.
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 VIDEO sockets, as the active input.
AUX 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 button once to select it and again to return to
the normal input selection.
Tape 1 is a tape Monitor function which does not override the current
input selection. For example, if the CD is the active input when TAPE 1
is selected, then the CD signal will continue to be selected and sent to
both the TAPE 2, and TAPE 1 OUTPUT sockets, but it is the sound from
recorder connected to Tape 1 that will be heard on the loudspeakers.
Apart from the amber indicator to show Tape 1 is engaged, the green
indicator for the active input will also stay lit.
NOTE: The remote control handset with the C 352 supplied is of a
universal NAD type, designed to operate several NAD models. Some
buttons on this handset are inoperative as the functions aren't
supported by the C 352. The Video 2 and Video 3 input selector buttons
on the remote control handset are inoperative in the case of the C 352.
6. SOFT CLIPPING™ INDICATOR
The green SOFT CLIPPING™ indicator shows that the Soft Clipping™
mode is engaged. Refer also to chapter "Rear Panel Connections",
section 12; "Soft Clipping™" for more information.

7. BASS & TREBLE CONTROLS
The NAD C 352 is fitted with BASS and TREBLE tone controls to adjust
the tonal balance of your system. The 12 o’clock position is ‘flat’ with
no boost or cut and a detent indicates this position. Rotate the control
clockwise to increase the amount of Bass or Treble. Rotate the control
anti-clockwise to decrease the amount of Bass or Treble. The Tone
controls do not affect recordings made using the Tape outputs but will
affect the signal going to the Pre-amp output (Pre Out).
8. TONE DEFEAT
The TONE DEFEAT switch bypasses the tone control section of the NAD
C 352. If the Tone Controls are not normally used and left in the 12
o'clock position, then it is advisable to switch out the Tone Control
section altogether by using this switch. In the 'out' position, the Tone
Control circuits are active, pushing the TONE DEFEAT switch 'in'
bypasses the Tone Control section.

POWERDRIVE
To meet the diverse requirements of high current drive and high
dynamic power, our patented PowerDrive amplifier circuit will build
further on our reputation for amazingly effective power. By adding a
second high-voltage rail to our well regulated high-current power
supply, we get an "overdrive" that can nearly double the continuous
power on a short term dynamic power basis. This is a further
development and refinement of our renowned Power Envelope circuit,
utilized by NAD in the 80's and 90's. PowerDrive differs from Power
Envelope in that it offers greater amplifier stability and low impedance
drive capability, resulting in less distortion when driving real speakers
with real program material.
RECORDING
TO MAKE A RECORDING
When any source is selected, its signal is also fed directly to any tape
machine connected to the TAPE 2 or TAPE 1 OUTPUTS for recording.
TAPE TO TAPE COPYING
You can copy between two tape machines connected to your NAD
C 352. 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 original tape.
REMOTE CONTROL HANDSET (FIGURE 3)
The Remote Control handset handles all the key functions of the NAD
C 352 and has additional controls to remotely operate NAD Tuners,
Cassette and CD machines. It will operate up to a distance of 16ft (5m).
Alkaline batteries are recommended for maximum operating life. Four
AAA (R 03) batteries should be fitted in the battery compartment at the
back of the Remote Control handset. 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.
MUTE
Press the MUTE Button to temporarily switch off the sound to the
speakers and headphones. Mute mode is indicated by the active input
indicator on the front panel flashing. Press MUTE again to restore sound.
Mute does not affect recordings made using the Tape outputs but will
affect the signal going to the Preamp output (Pre Out).
INPUTS
The input selector buttons perform the same functions as the buttons
labelled the same on the front panel.
MASTER VOLUME
Press the MASTER VOLUME
or
buttons to respectively
increase or decrease the loudness level. Release the button when the
desired level is reached. The motorised Volume Control on the front
panel will indicate the level set. The Master Volume buttons do not
affect recordings made using the Tape outputs but will affect the signal
going to the Preamp output (Pre Out).

10. VOLUME
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 but will affect the signal going to the Preamp output (Pre Out).
DEUTSCH
Rotating the control clockwise moves the balance towards the right.
Rotating the control anti-clockwise moves the balance to the left. The
BALANCE control does not affect recordings made using the Tape
outputs but will affect the signal going to the Pre-amp output (Pre Out).
POWER ON AND OFF BUTTONS
The NAD C 352 remote has a separate On and Off button. This can be
particularly useful to keep components within a system "in sync": This
way all components will switch to stand-by when Off is pressed or
switch to operating mode when On is pressed, instead of some
components switching On when the amplifier is switched to Stand-by.
(Note that the other components have to be capable of responding to
the separate On and Off commands as well). Press the ON button to
switch the unit from Stand-by to the operating mode; The Stand-by
indicator (Fig. 2; No. 2) will turn from amber, to red, then to green and
the indicator for the last selected input will blink and light up. Press the
OFF button to switch the unit to the Stand-by mode: The Stand-by
indicator will light up amber.
