The LS9 is an all-new,
all-solid-state line level preamplifier which replaces the LS3/3B
series. Using a low-voltage, pure Class A gain circuit with
direct-coupled output (no coupling caps are used in the signal path),
the LS9 yields 12dB of overall gain (factory adjustable to 18dB gain if
necessary). Output capability is a substantial 24V RMS from the balanced
main outputs. The LS9 also features complete IR remote control of all
front panel functions, including a 70-step electronic relay volume
attenuator and input selection. The LS9 offers two pairs of dedicated
balanced inputs, three pairs of dedicated single-ended inputs; and a
full tape monitor loop (single-ended in and out) is also provided.
The LS9 is designed to be left on continuously, drawing only 20 watts
maximum continuous power. Housed in full-width 3.5" high chassis, the
LS9 is a model of slim elegance that will fit neatly into almost any
conceivable cabinet or shelving system. Since it generates very little
heat internally, it may safely be left behind closed doors when not in
use.
