Amazing FlexibilityAs with every amp in the Classic Series, we here at NAD have carefully thought through all the possible use cases and strategically chosen the most essential of features. Thanks to selectable balanced inputs, the C 268 is a natural mate for high-end preamps and processors. These inputs include a trim control useful for matching with other components, or for use in bi-amping speakers. A line out allows further addition of power on the same channel for extra speakers or subwoofers. On top of all this connectivity is a bridge switch that turns the C 268 into an amazingly powerful Monobloc amplifier.You can also pair the C 268 with the NAD C 368 Hybrid Digital DAC Amplifier, and with both units bridged for mono, 300 watts per channel of distortion-free sound become available for your listening pleasure. The C 268’s auto-sense feature with selectable threshold is perfect for automating complex systems or for hiding the amp out of sight in a cabinet. Included with the C 268 is a ground lug that is very useful for eliminating ground loops and noise in complex multi-unit systems.Getting the Basics RightAs a member of NAD’s Classic Series, the C 268 delivers a richly satisfying sonic performance thanks to its “music-first” features. Accurate channel balance, proper input and output impedance characteristics, and low noise circuits all come together within this one stereo power amplifier. Additionally the C 268’s line inputs, both balanced and single-ended, can accommodate all kinds of analogue source components by offering ideal input impedance traits with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation caused by unfitting loading of the source device.Sophisticated PowerHaving moved away from old fashioned linear power supplies and Class AB output stages, NAD has developed even better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, NAD’s advanced work in this area has resulted in some of the best performing amplifiers regardless of basic design principle. The overall design of the C 268 is very linear over a wide bandwidth, providing dramatic advances over previous models with consistent performance into all speaker loads.The power supply of the C 268 is capable of nearly 200 watts continuously and over 500 watts instantaneously, allowing for short term musical transients. NAD’s innovative asymmetrical PowerDrive fully utilizes every last watt available with its vast reserves of dynamic power available to accurately reproduce the most demanding music without distortion or compression. It can also operate with any AC mains voltage from 100V to 240V, and provides pure DC power to all the various stages of the C 268. This highly efficient supply also provides near perfect regulation of voltage across a wide range of conditions and provides a solid noise-free foundation for the amplifying stages.The C 268 uses a customised version of the proven Hypex UcD output stage. This allows for massive power with nearly immeasurable distortion and noise in the audible range. Every detail of this design has been carefully crafted and perfectly executed to wring out ever last drop of performance.

Amazing Flexibility The C 298 may be a basic Power Amp, but we have carefully thought through all the use cases typically encountered to create a rich feature content. Selectable balanced inputs make the C 298 a natural for studio use or connection to High End Preamps and Processors. These inputs include a trim control useful for matching to other components. A line out allows further addition of power on the same channel for additional speakers or subwoofers. Auto-sense with selectable threshold is perfect for automating complex systems or hiding the amp out of sight in a cabinet. We even include a Ground Lug that can be very useful for eliminating ground loops and noise in complex multi-unit systems. Added to all this connectivity is a Bridge Switch that turns the C 298 into an amazingly powerful Monobloc Amplifier. Start with one and add a second C 298 later when you upgrade your speakers. Getting the Basics Right It is surprising how many seemingly advanced products in the market today often miss many of the most basic requirements for satisfying performance. Low noise circuits, accurate channel balance, proper input and output impedance characteristics, high overload margins and stability with difficult speaker loads. NAD starts by getting these things precisely right and advances from there. Our line inputs, both Balanced and Single-ended, can accommodate all kinds of analog source components by offering ideal input impedance characteristics with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation caused by inappropriate loading of the source device. These are all details you can hear. Sophisticated Power NAD has moved away from the old fashioned and very power hungry linear power supplies and Class AB output stages that waste nearly half of the energy consumed producing heat rather than sound. Instead we have developed even better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, NAD’s advanced work in this area has created some of the best performing amplifiers regardless of basic design principle. These new designs are very linear over a wide bandwidth and provide consistent performance into all speaker loads, providing a dramatic advance over previous models. The generously dimensioned power supply easily allows for 185 watts continuous and over 570 watts instantaneous power for short term musical transients. Innovative Asymmetrical Power-Drive fully utilizes every last watt available with its vast reserves of dynamic power available to accurately reproduce musical transients without distortion or compression. It can operate with any AC mains voltage from 100v to 240v and provides pure DC power to all the various stages of the C 298. This highly efficient supply also provides near perfect regulation of voltage across a wide range of conditions and provides a solid noise-free foundation for the amplifying stages.

Connect to the emotion of live performance through detailed sound, with both amazing control and transparency. This is the M22. While it is easy to find amplifiers that can excel in one or two areas, the M22 is an amplifier that truly does everything well. Wide open-loop bandwidth, extremely low-phase shift, almost non-existent noise, and high current capability all add up to one incredible performance.Wielding NAD’s PowerDrive™ circuit topology, the M22 delivers unbelievable power to any loudspeaker. Distortion and noise become functionally nonexistent and nearly unmeasureable thanks to the M22’s switch mode design, resulting in a clear, vivid sound. Possessing harmonic and intermodulation distortion independent of load, as well as low output impedance uniformly at all audible frequencies, the M22 is a powerhouse unit built to break down barriers to good sound. You just have to hear it to feel it.Hybrid Digital AmplificationThe M22 is using the latest nCore™ amplifier technology licensed from Hypex to provide a nearly ideal amplifier with distortion below measurement, ultra-high damping factor, and unconditional stability with any speaker. Tight, detailed sound with amazing control and transparency gets the best performance available. With nCore, Hypex has refined their UcD concept to new levels of perfection by improving the modulator for more accurate feedback subtraction and PWM generation.The all-discrete driver and output stage have also been improved for lower open-loop THD as well as lower idling losses, normally conflicting requirements with conventional IC driver circuitry. An added control loop incorporating an integrator with adaptive clipping enables 20dB more feedback to be used across the audio band because of its extremely low-phase shift resulting in a dramatic reduction in distortion across the audio band. This is added to UcD’s already amazing characteristics of load invariance and high current capability, common characteristics of great-sounding amplifiers.Effortless PowerEmploying the latest generation of digital PowerDrive™ the M22 offers a minimum of 250W per channel with amazing reserves of dynamic power at lower impedances. The M22 is capable of >300W dynamic power per channel even in 8 ohms, and >600W in 2 ohms. It can effortlessly power any loudspeaker to live performance levels with amazing efficiency and low power consumption. Control for PowerDrive is derived by sensing the average output power, applying a time constant, and then cleanly hard clipping the signal thus limiting it to the rated continuous clipping power over a sustained loading.Perfecting PerformanceThe output stage is only one of several circuits in the amplifier, and each must complement the other to obtain optimal performance. The amp is DC coupled throughout, from input to output, there is no capacitor in the forward signal path. Yet, it has a beneficial 12dB/octave roll-off below 2Hz. It does this using a unique circuit topology that is functionally a forward servo. It is however not a servo in the traditional sense as it does not measure DC at the output and send back a correction signal. Instead part of the input signal is fed to a side chain with a second order low-pass filter. The output of this is subtracted from the forward signal input to the second stage thus rejecting DC.Clean and DynamicThe performance of the entire signal path is critically dependent on the power supply; in this case a well regulated, but not too tight, custom switch mode design. This allows maximum dynamic power, very high current yet with very low distortion. Secondary supplies are individually regulated and decoupled at each opamp for lowest possible noise and maximum dynamic range.
