LA-1 - Line Amplifier
LA-1  -  Price: $199.00

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.
