The Klipsch Sub-120 offers flexible connection options to integrate with almost any AV receiver or stereo system.
- LFE-Eingang (Niederfrequenzeffekte): For receivers with a dedicated subwoofer output (LFE or SUB OUT), connect a single RCA cable from the receiver's subwoofer output to the LFE input on the subwoofer. This is the recommended connection for home theater systems.
- Line In (Stereo RCA Inputs): If your receiver does not have an LFE output, connect stereo RCA cables from your receiver's pre-out (left and right) to the corresponding Line In (L/R) inputs on the subwoofer.
