C 326BEE Stereo Integrated Amplifier

> POSITIONING

The NAD C 320 series of amplifiers have always punched far above their modest weight. Combining the highest levels of audio engineering with an extensive feature list, and more than adequate power for all but the most ambitious systems, the C 326BEE keeps the concept of affordable hi-end alive and well. With the very high dynamic power and low impedance drive capability of NADs proprietary PowerDrive circuit, the C 326BEE is able to accurately control even difficult to drive loudspeakers while sounding musical, detailed, coherent and relaxed. The C 326BEE is the latest in NADs range of affordably priced, yet very high performance Stereo Integrated Amplifiers. Neatly slotted in between our most affordable C 315BEE and more powerful C 355BEE, the C 326BEE boasts many upgrades and refinements taken directly from the highly acclaimed NAD Masters Series M3 Amplifier. These include application of Bjorn Erik Edvardsens 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 must be heard to be fully appreciated!

> DETAILS
Features The C 326BEE is fully remote controlled and comes supplied with the NAD SR 8 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 8 will also operate many other NAD products such as CD players, tuners, etc. Flexibility is another NAD strong point. The C 326BEE has 7 line inputs and the pre-amplifier section can be separated from the power amplifier for easy upgrades or adding ancillary equipment. Thus the C 326BEE can be expanded to meet future system needs. The C 326BEE sports a pre-amp output: 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). continued>

Additionally, there are two monophonic Subwoofer OUT that can be connected to powered subwoofers - an increasingly popular option. For remote on/off switching of ancillary components in a system, such as power amplifiers or active speakers, the C 326BEE 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 switching on the remote devices. Besides the 12V-trigger, the C 326BEE also has rear panel IR IN and OUT. 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 326BEE 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 control button. The C 326BEE also incorporates NADs acclaimed switchable Soft Clipping circuit, which significantly reduces the risk of damage to loudspeakers due to prolonged high power operation. Design: PowerDrive The C 326BEE also benefits from NADs proprietary PowerDrive circuit topology, now well established and used throughout the NAD product range. The PowerDrive topology allows the C 326BEE 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. The C 326BEE has the lowest levels of distortion and noise available in its price class and is easily capable of embarrassing far more expensive products. To prove it, NAD uses Full Disclosure Power (FDP) - the most demanding criteria for performance measurement. FDP specifies distortion under the most extreme conditions of low impedance loads and frequency extremes rather than the simple and easy 1kHz @ 8 Ohms test quoted by many of our competitors. We use this stricter performance criterion because it more closely matches the demands of real music and real loudspeakers. Maintaining specified distortion at 4 Ohms and at 20Hz and 20kHz is several orders of magnitude more difficult to achieve than the simple 8 Ohms and 1kHz test. 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 cant match our very conservative spec of 0.009% at any frequency within the range of human hearing. Our noise spec is often 10dB (100 times!) less than that of competing amplifiers. This is far from a trivial difference as fine detail and nuance (micro dynamics) are often obscured by noise in lesser amplifiers, robbing a performance of that illusive sense of realism. It is that exciting feeling of being there at the live performance. 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 dont think youll find anything that comes close to offering the C 326BEEs overall musical satisfaction, well-rounded performance, and stellar value for money.

INTRODUCTION

GETTING STARTED

UNPACKING AND SETUP

WHATS IN THE BOX Packed with your C326BEE you will find: The SR8 remote control with 2 (two) AA batteries This owners manual A detachable AC power cord SAVE THE PACKAGING Please save the box and all of the packaging in which your C326BEE arrived. Should you move or otherwise need to transport your C326BEE, this is by far the safest container in which to do so. Weve 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 23 feet/7 meters, between the C326BEEs front panel and your primary listening/viewing position. This will ensure reliable infrared remote control communications. The C326BEE generates a modest amount of heat, but nothing that should trouble adjacent components. It is perfectly possible to stack the C326BEE atop other components, but the reverse usually should be avoided. It is especially important that sufficient ventilation be provided. If you are contemplating locating the C326BEE within a cabinet or other furniture, consult your NAD audio/video specialist for advice on providing adequate airflow. NOTES ON INSTALLATION Your NAD C326BEE should be placed on a firm, 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-flow through the ventilation slots. Make sure the unit is switched off before making any connections. The RCA sockets on your NAD C326BEE 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 firmly 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 C326BEE, 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-SERVICEABLE 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.

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 terminals 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 terminals 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.

10MAIN IN: Connections to an external pre-amplifier or processor, such as a surround-sound decoder. In normal use, this should be connected to PRE OUT sockets with the links supplied. To connect your NAD C326BEE to external processor or pre-amplifier, remove first these links. Use a twin RCA-to-RCA lead to connect the left and right Audio Output of the pre-amp or processor to the Main In sockets. Always turn the C326BEE and associated external power amplifiers OFF before connecting or disconnecting anything to the MAIN IN sockets. 11 SOFT CLIPPING: Enables NADs proprietary Soft Clipping circuitry on all channels. At [ON] position, Soft Clipping gently limits the output of the C326BEE to minimize audible distortion should the amplifier be over-driven. Soft Clipping may simply be left ON at all times to reduce the likelihood of audible distortion from excessive volume settings. However, for critical listening and to preserve optimum dynamics, you may wish to defeat it by setting this switch to OFF position. The SOFT CLIPPING indicator on the front panel will illuminate when the C326BEE is in Soft Clipping mode. Refer also to the item below about POWERDRIVE. POWERDRIVE The C326BEE uses NADs proprietary PowerDrive amplifier technology for all channels to preserve accurate, linear reproduction regardless of the loudspeaker. This uniquely efficient power-supply topology provides the real-world benefits of high dynamic power that remains uncompromised by low-impedance speakers. By adding a second high-voltage rail to our well regulated highcurrent power supply, we get an overdrive that can nearly double the continuous power on a short term dynamic power basis. PowerDrive offers greater amplifier stability and low impedance drive capability, resulting in less distortion when driving real speakers with real program material. 12 +12V TRIGGER OUT: The +12V TRIGGER OUT is used for controlling external equipment that is equipped with a +12V trigger input. This output will be 12V when the C326BEE is ON and 0V when the unit is either OFF or in standby. This output can drive a load up to 50mA at 12V. 13IR IN/OUT: These mini-jacks accept and output remote-controlled codes in electrical format, using industry-standard protocols, for use with IR-repeater and multi-room systems and related technologies. IR IN: This input is connected to the output of an IR (infrared) repeater (Xantech or similar) or the IR output of another component to allow control of the C326BEE from a remote location. IR OUT: When connected to the IR IN of an ancillary equipment, direct the ancillary equipments own remote control to the C326BEEs infrared receiver to command or control the linked unit. All NAD products with IR IN/IR OUT features are fully compatible with the C326BEE. For non-NAD models, please check with your other products service specialists as to their compatibility with the C326BEEs IR features. 14 SPEAKERS: 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 loudspeakers - 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 C326BEE. 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. The C326BEE is designed to produce optimum sound quality when connected to speakers with impedances within its operating range. Please make sure that all the speakers are rated 4 ohms minimum per speaker. 15POWER SWITCH: The POWER switch supplies the master AC mains power for the C326BEE. When this switch is at ON position, the C326BEE is in standby mode as shown by the amber status condition of the standby LED. Toggle the front panels STANDBY button to switch ON the C326BEE or back to standby mode. If you intend not to use the C326BEE for long periods of time (such as when on vacation), switch the POWER switch to the OFF position. When the POWER switch is at OFF position, the front panel power button or SR8 remote control cannot activate the C326BEE. 16AC MAINS INPUT: The C326BEE 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 C326BEEs AC Mains input socket first. Connect only to the prescribed AC Outlet, i.e., 120V 60 Hz (120 V version model only) or 230V 50 Hz (230 V vesion model only). Always disconnect the AC Mains cable plug from the live wall socket first, before disconnecting the cable from the C326BEEs Mains input socket.
