The Atlas Sound TSD-TXHL is a handy device that can convert a 100V Line or low impedance (down to 4 Ohm) speaker level signal to a line-level signal.

This is ideal for routing an audio signal to other devices such as an active subwoofer or amplifier, when your primary amplifier doesn't have a line output. It's also great for connecting devices such as these when the primary amplifier is too far away for a normal line-level signal.

The TSD-TXHL is a passive unit meaning no external power is required and features a volume control to adjust the volume to your liking. There is a switch to toggle between your speaker level input (4 Ohm, 25V, 70V and 100V), and phoenix terminals to connect the speaker inputs and output.


An example could be an amplifier in a storage room, and a subwoofer in the front of house. It may be impractical to connect a normal line-level signal due to the distance between the two devices, however a feed from a nearby speaker could be routed to the subwoofer, with the TSD-TXHL connecting them.
