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.
