About this item
The RDL TX-8A 4 Ohm/8 Ohm Input Interface is a mono audio transformer that can convert the output of a 4 or 8 Ohm amplifier into a line level input to be sent to an audio mixer or second amplifier. The transformer's frequency response extends low enough to make it suitable for feeding a subwoofer amplifier input. For situations when interfacing between a stereo output to a subwoofer input, two TX-8A modules may be used, one from each side of the stereo output signal, with their inputs combined as the subwoofer input.
