  If your ELAC Subwoofer shows no signal, first verify the mains fuse and replace it if necessary. Next, ensure that the subwoofer is properly connected to the mains, checking the switch, plugs, and socket. Then, confirm that the power mode switch is set to either AUTO or ON. Finally, check the input connections and RCA connectors, and verify the signal source by testing if another audio component connected to the same source is working correctly.

  If the max output of your ELAC Subwoofer is slightly too low in your living room, try placing the subwoofer in front of a wall or in a corner. This can help improve the bass response.

What to do if ELAC Subwoofer output level is too low (RCA jack)?

  If the output level of your ELAC Subwoofer is too low when using the RCA jack, it could be due to a low output level from the source, such as the pre-amp or surround decoder. Try increasing the output level of the pre-amp to a minimum of 0.2 Volts, and then reduce the power amp level to compensate. Alternatively, slightly reduce the gain for the main (center, effect) speakers and increase the master volume.

Why is the output level too low on my ELAC SUB 2040 ESP Subwoofer (speaker cable)?

  If the output level of your ELAC Subwoofer is too low when using a speaker cable, it's possible that one channel is inverted. To check this, disconnect one channel. If the bass level increases, reconnect the second channel with inverted polarity. Also, inspect the cables for any polarity errors.
