NAD 1300 pre-amplifier

The 1300 was designed for the technically sophisticated audiophile who requires both state-of-the-art. sound and a high degree of operating flexibility

For listeners who are committed to the LP as an important source of music, the 1300 contains a highdefinition FET-input phono preamplifier with excellent sound-stage imaging and astonishing resolution of inner detail. No trace of slew-limiting or transient distortion can be found, even in high-level signal peaks 25 dB above normal level. Selectable input capacitance and precise RIAA equalisation ensure that the sound of each recording is accurately preserved

Using eight selected low-noise transistors per channel, this MM phono circuit provides unusually effective rejection of radio-frequency Interference from nearby digital circuits, cordless phones, and radio/TV transmitters. It is supplemented by an elegantly simple class-A preamplifier that provides quieter play-back with low-output moving-cod pick-ups than most preamps provide with a high-output MM cartridge

In addition to the features described on the preceding pages, the 1300 includes a special “Null” circuit that electronically subtracts any monaural information from the audio signal. Using this feature, you can easily align your cartridge for perfect electrical balance or adjust your FM antenna for minimum multipath distortion

With its bi-directional taping circuits and a separate EPL circuit for an external processor, the 1300 offers unmatched flexibility. All of its line-level circuits, including its unique volume and tone controls, have the high headroom and ultra-low noise required to accommodate both today’s and tomorrow’s digital sources. The dynamic range of the 1300, relative to the 2-volt maximum output of a CD player, exceeds 110 dB. But the most important characteristic of this preamp is the simplicity and sonic purity of its  primary signal path. Yet its price is surprisingly low in comparison with other preamps that don’t soundas good and give you less control.
