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.
The front panel level control of the transformer allows you to adjust the input power voltage to -10 dBV or +4 dBu. The unit can handle between 0.5 and 400 W of operational power and can be wired to output either balanced or unbalanced signals.
For easy wiring, the unit features detachable terminal block connections. To couple the audio input to the audio output, the transformer features bifilar coil windings. To prevent ground loops, the device is built with galvanic isolation. For convenience, the transformer may be mounted on the sides of a rack or on the rack rails using RDL's optional TX mounting accessories.
