supply parameters of the amplifier to best cope with the actual musical signal and specific speaker loading characteristics. - Soft Clipping eliminates the harsh sound that occurs when an amplifier is overdriven. This feature also protects sensitive loudspeaker tweeters that can be easily damaged by the high frequency distortion caused by clipping (clipping describes the distorted shape of a musical sine wave when an amplifier is driven beyond its power rating). - BEE Clamp is a new answer to an old problem endemic to all transistor amplifier designs. When the output transistors produce heat faster than it can be dissipated, the amplifier becomes momentarily unstable. This happens when the music has rich high frequency content and the speaker has low or difficult impedance. The BEE Clamp employs sophisticated real time monitoring of the output transistors load and drive and clamps the base drive to prevent saturation when necessary, thus improving amplifier stability and waveform fidelity. The C325BEE can instantly recover from overload, reducing both the amount and the duration of distortion, regardless of load impedance. NAD has a deeper understanding of the nature of musical sounds and has devised innovative circuits that overcome the limitations of semiconductors, capacitors, and the other electronic components that make up an amplifier. This innovation has resulted in a product that truly excels in the reproduction of music. How we made the best better The C320BEE and its predecessors has been the benchmark for budget amplifiers for 30 years now, having won every award in the Hi-Fi industry several times over. Making the C325BEE better than the C320BEE was a tall order! By trickling down several innovations from NADs new state-of-the-art Masters Series products has resulted in the C325BEE having even less distortion, less noise, and a more detailed rendition of the musical recording. - New DC Servo eliminates sound colouring capacitors in the signal path. This improves musical detail and eliminates harmful loudspeaker offset. - Patented distortion cancelling circuit uses both feedback and feedforward to reduce distortion and improve amplifier stability. - Highly optimised circuit layout further lowers internal impedance, improves grounding, and eliminates subtle magnetic distortions. Lower noise and distortion, and improved channel separation are a direct result of this optimisation. - Surface mount (SMD) technology shortens signal paths and lowers distortion in NADs proprietary Class A gain modules. - BEE Clamp improv es HF stability when driving difficult speakers. - Volume Control has minimum volume cancellation circuit to increase attenuation by 10dB. - Tone controls are hand trimmed for perfect response characteristics. - A new idling current circuit is more accurate with less unit-to- unit variation. - More rigid chassis has improved mechanical integrity. - MP Input for easy connection of iPod™, MP3 and other Media Players employing 3.5mm headphone sockets. Value, redefined NAD has yet further improved the class leading amplifier using new technology developed for its range topping Masters Series components. The C325BEE is the new benchmark against which all other affordable amplifiers will be compared. As with the previous iterations of this classic NAD amplifier, you will have to spend several times the C325BEEs asking price before you can even approach the technical precision and musical involvement offered by this unassuming looking little amplifier. All this sophistication and refinement is available now in the NAD C325BEE; the new value leader in affordable Hi-Fi!
