Details
The C355BEE is the latest in NAD’s range of affordable, yet very high performance Integrated Amplifiers.
Building on the strengths of our highly acclaimed C352 (winner of What Hi-Fi Amplifier-of-the-Year and the
Hi-Fi Choice Gold Award among many others), the C355BEE boasts many upgrades and refinements taken
directly from the highly acclaimed NAD Masters Series M3 Amplifier. These include the application of Bjorn
Erik Edvardsen’s innovative and patented Distortion Canceling Circuit in the output stage and BEE Clamp in
the power supply. 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 C355BEE is fully remote controlled and comes supplied with the NAD SR 6 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 6 will also operate many other NAD products
such as CD players, tuners, etc.
Flexibility is another NAD strong point. The C355BEE 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 C355BEE can be expanded to meet future system needs. The
C355BEE sports 2 pre-amp 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 C272, which has identical amplification
factor (gain) as the C355BEE’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 C355BEE is equipped with a 12V-trigger system. When switching the amplifier on, the 12Vtrigger output is also activated which in turn can activate a 12V-trigger input and switch on the remote
devices. Besides the 12V-trigger, the C355BEE also has rear panel IR in and out and an RS-232 port to
allow interface to advanced home automation systems. In fact, NAD is a ‘certified partner’ with AMX and
Crestron, leaders in the field of home automation guaranteeing compatibility with these systems.

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 C355BEE tone controls only work at the frequency
extremes leaving the critical mid-band essentially unaltered. The
tone control circuits can be completely bypassed by using the tone
defeat switch. The C355BEE 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 C355BEE also benefits from NAD’s proprietary PowerDrive
circuit topology, now well established and used throughout
the NAD product range. The PowerDrive topology allows the
C355BEE 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 for enabling 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.
Less Distortion = More Music
Noise and distortion mask the fine details of a musical recording
robbing musical texture and dimension and replacing them with
non-musical artifacts. NAD has spent the last 35 years perfecting
our designs to have the lowest distortion and highest power in its
price class. This cannot be overstated! Our competitors often rate
distortion at only 80% of rated power, and even then can’t match
our very conservative spec of 0.03% at any frequency within the
range of human hearing. At 80% power our distortion drops to
0.005% or less. Our noise spec is often 10dB (100 times!) less
than that of competing amplifiers. This is far from trivial.
However, 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 C355BEE’s overall musical satisfaction, well-rounded
performance, and stellar value for money.

GETTING STARTED
UNPACKING AND SETUP
WHAT’S IN THE BOX
Packed with your C 355BEE you will nd:
• The SR 6 remote control with 2 (two) AAA batteries
• This owner’s manual
SAVE THE PACKAGING
Please save the box and all of the packaging in which your C 355BEE
arrived. Should you move or otherwise need to transport your receiver,
this is by far the safest container in which to do so. We’ve seen too many
otherwise perfect components damaged in transit for lack of a proper
shipping carton, so please: Save that box!
CHOOSING A LOCATION
Choose a location that is well ventilated (with at least several inches to
both sides and behind), and that will provide a clear line of sight, within
25 feet/8 meters, between the C 355BEE’s front panel and your primary
listening/viewing position. This will ensure reliable infrared remote control
communications. The C 355BEE generates a modest amount of heat, but
nothing that should trouble adjacent components. It is perfectly possible to
stack the C 355BEE on top of other components.
NOTES ON INSTALLATION
Your NAD C 355BEE should be placed on a rm, 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 a bookcase or cabinet that
may impede the air-ow through the ventilation slots. Make sure the unit is
switched o before making any connections.
The RCA sockets on your NAD C 355BEE are colour coded for convenience.
Red and white are Right and Left audio respectively.
Use high quality leads and sockets for optimum performance and reliability.
Ensure that leads and sockets are not damaged in any way and all sockets
are rmly pushed home.
For best performance, use quality speaker leads of 16 gauge (1.5mm)
thickness or more. 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 C 355BEE, shut o the power to the unit
and remove the plug from the AC socket. Have the unit inspected by a
qualied service technician before attempting to use it again.
BARE WIRES AND PIN CONNECTORS
WARNING: The terminals marked with this symbol
are hazardous live. External wiring connected to these
terminals requires installation by an instructed person or
the use of ready-made leads or cords.
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.
QUICK START
In case you simply cannot wait to experience the performance of your new
NAD C 355BEE, we provide the following “Quick Start” instructions to get
you underway.
Please make all the connections to your C 355BEE with the unit unplugged.

9 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.
10 TAPE MONITOR 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 MONITOR IN sockets for playback and tape
monitoring. Connect the left and right ‘Audio Input’ of the tape machine
to the TAPE MONITOR OUT sockets for 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 OUT or TAPE MONITOR OUT for
recording.
TAPE TO TAPE COPYING
You can copy between two tape machines connected to your NAD
C 355BEE. Put the source tape in the recorder connected to Tape 2 and the
blank tape into the recorder connected to Tape Monitor. By selecting TAPE
2 input you can now record from Tape 2 to Tape Monitor and monitor the
signal coming from the original tape.
NOTE
There will be no Tape 2 output when Tape 2 (or Tape Monitor OUT when
Tape Monitor) is the selected source input. This prevents feedback
through the recording component thereby preventing possible damage
to your speakers.
11 PRE OUT 1: The PRE OUT 1 sockets can be used to drive an additional
power amplier. Use a twin RCA-to-RCA lead to connect to the left and
right ‘Audio Input’ of the Power amplier or processor to the PRE OUT 1
sockets.
12 PRE OUT 2: Connections to an external power amplier or processor,
such as a surround-sound decoder. In normal use, these should be
connected to the Main-In sockets (No. 13) with the links supplied. To
connect your NAD C 355BEE to external processor or amplier sections,
remove rst 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
Always turn the C 355BEE and associated external power ampliers OFF
before connecting or disconnecting anything to the PRE OUT 1, 2 and
MAIN IN sockets. The PRE OUT 1 and 2 output signals will be aected by
the C 355BEE’s volume and tone control settings.
14 SOFT CLIPPING™: When an amplier is driven beyond its specied
power output, a hard, distorted sound can be heard on very loud
sounds. This is caused by the amplier cutting o or ‘hard clipping’ the
peaks of sound that was not designed to reproduce. The NAD Soft
Clipping circuit gently limits the output of the system to minimise
audible distortion if the amplier 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 amplier’s
power capability, then switch Soft Clipping ON. The Soft Clipping™ LED
on the front panel will illuminate when the amplier is in Soft Clipping
mode.
15 SPEAKERS A, B: The C 355BEE is equipped with two sets of speaker
connectors. Use the Speakers A connectors for the ‘main’ speakers and
use the Speakers B connectors for a second pair, for example, extension
speakers located in another room.
Connect the right speaker to the terminals marked ‘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 355BEE. The high-current 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.
16 SWITCHED AC OUTLET (North America version only): The
SWITCHED AC OUTLET can supply switched power to another
component or accessory. This convenience outlet can be switched
ON or OFF using only the POWER switch located at the rear panel. The
SWITCHED AC OUTLET cannot be switched ON or OFF using the front
panel Standby button or the ON/OFF button of the remote control. The
total draw of all devices connected to this Switched AC outlet must not
exceed 120 watts.
17 IEC AC MAINS (POWER) INPUT: The C 355BEE comes supplied with
a separate AC Mains cable. Before connecting the cable to a live wall
socket ensure that it is rmly connected to the NAD C 355BEE’s AC
Mains input socket rst. Always disconnect the AC Mains cable plug
from the live wall socket rst, before disconnecting the cable from the
C 355BEE Mains input socket.
18 POWER SWITCH: The POWER switch supplies the master AC mains
power for the C 355BEE. When the switch is in the ON position the
C 355BEE is in standby as shown by the amber Status Condition LED,
above the Standby button on the front panel. If you intend not to use the
amplier for long periods of time, switch the POWER switch to the OFF
position.
13 MAIN IN: Connections to an external pre-amplier or processor, such as
a surround-sound decoder. In normal use, these should be connected
to PRE OUT 2 sockets (No. 12) with the links supplied. To connect your
NAD C 355BEE to external processor or pre-amplier rst 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.
NOTE
Always turn the amplier o before connecting or disconnecting
anything from to PRE OUT 1, 2 and MAIN IN sockets.

SR 6 REMOTE CONTROL
The SR 6 remote control handset handles the key functions of the
C 355BEE as well as other NAD Stereo Receivers, Integrated Ampliers
and Preampliers. It has additional controls to remotely operate NAD CD
Players, FM/AM Tuners and dedicated FM/AM/DAB Tuners. It will operate
up to a distance of 16ft (5m). Alkaline batteries are recommended for
maximum operating life. Two AAA (R 03) batteries should be tted in the
battery compartment at the rear 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.
When a command from the remote control is received, the Standby/
protection indicator will blink. Note that the indicator may also blink
when receiving commands not necessarily for the C 355BEE but for other
components in the system. Please refer to previous sections of the manual
for a full description of individual functions.
1 POWER ON & OFF: The SR 6 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 standby when
OFF is pressed or switched to operating mode when ON is pressed
- instead of some components switching ON when the C 355BEE is
switched to Standby. (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 Standby to operating
mode; The Power/Standby/Protection LED indicator will turn from
amber, to red, then to green and the indicator for the last selected
