1300

Stereo Preamplifier

Date of manufacture : Jan 87 - Feb 89

Please note that this document contains the text from the original product brochure, and some technical statements may now be out of date

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 high-

definition 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 sound

as good and give you less control.
