DESCRIPTION
The ALTEC LANSING Model 15515A Input Bridging Transformer is a line level transformer designed to "bridge" a low impedance source to a high impedance input while providing full transformer isolation. The transformer is internally mounted on a small printed circuit board to which optional resistors forming a resistive pad may be installed. This provides a convenier.t mounting location for a pad should one be necessary and the snap-a-part case facilitates installation. Tables of pre-calculated resistor values for typical losses are also provided. The plug-in transformer is an accessory for use with all Anniversary Series power amplifier products.
