The NAD C320 is a descendant of our original 3020 integrated amplifier, the world's best-seller in its category. Times have changed, and this new model does not have a phono preamp. NAD Link Introducing the C320. This amplifier is the latest in the family of NAD's modestly priced integrated amplifiers which stretch back to the legendary 3020. One step up from the splendid 310, the C320 is fully remote controlled with the NAD C Series system controller and is destined to become yet another NAD classic.
Tone controls tend to come and go on amplifiers, depending on whatever is in vogue at the time.
This does not mean that tone controls should necessarily be regarded as a superfluous extra. Given proper thought and design, tone controls can make a genuine contribution to overall sound quality. The C320 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 circuitry automatically recognises the impedance characteristics of the loudspeaker and will then adjust its power supply settings to best cope with that specific load.
