The LA-1 is a one-in, two-out line/distribution amplifier with front
panel variable gain adjustments from -20 to +20 dB. A center detent
is supplied for unity gain. A bi-colored signal indicating LED furnishes
a green indication when a signal of a predetermined threshold is present
(usually just below the house reference level) and a flashing red-green
indication when the module approaches overload at the output. The input
to the amplifier uses a common mode filter to ensure very high rejection
of common mode RF energy. The module has a balanced output section that
uses a new current boost integrated circuit, which is almost totally
free from crossover distortion. Each LA-1 has two 60 ohm outputs (150
ohm also available). On board fuses assure the continued operation of
the system in the highly unlikely event of a catastrophic failure of an
amplifier module.
