Solid state stereo line stage.
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.
