1300 Stereo PreamplifierDate of manufacture : Jan 87 - Feb 89Please note that this document contains the text from the original product brochure, and some technical statements may now be out of dateThe 1300 was designed for the technically sophisticated audiophile who requires both state-of-the-artsound and a high degree of operating flexibilityFor listeners who are committed to the LP as an important source of music, the 1300 contains a high-definition FET-input phono preamplifier with excellent sound-stage imaging and astonishing resolution ofinner detail. No trace of slew-limiting or transient distortion can be found, even in high-level signalpeaks 25 dB above normal level. Selectable input capacitance and precise RIAA equalisation ensure thatthe sound of each recording is accurately preservedUsing eight selected low-noise transistors per channel, this MM phono circuit provides unusuallyeffective rejection of radio-frequency Interference from nearby digital circuits, cordless phones, andradio/TV transmitters. It is supplemented by an elegantly simple class-A preamplifier that provides quieterplay-back with low-output moving-cod pick-ups than most preamps provide with a high-output MMcartridgeIn addition to the features described on the preceding pages, the 1300 includes a special “Null” circuitthat electronically subtracts any monaural information from the audio signal. Using this feature, you caneasily align your cartridge for perfect electrical balance or adjust your FM antenna for minimummultipath distortionWith its bi-directional taping circuits and a separate EPL circuit for an external processor, the 1300 offersunmatched flexibility. All of its line-level circuits, including its unique volume and tone controls, have thehigh headroom and ultra-low noise required to accommodate both today’s and tomorrow’s digitalsources. The dynamic range of the 1300, relative to the 2-volt maximum output of a CD player, exceeds110 dB. But the most important characteristic of this preamp is the simplicity and sonic purity of itsprimary signal path. Yet its price is surprisingly low in comparison with other preamps that don’t soundas good and give you less control.
