LFE channel voltage?

LFE channel voltage?

Youngling Posts: 1 Join Date: 2/13/10 Recent Posts
Hello,

I have AV amp whose RCA pre-outs have (presumably normal?) specifications of 1V/1.2kOhms, but the subwoofer output is specced 4V/1.2kOhms. Is this normal, and especially is it safe to plug into the LFE input of my new 5040a?

regards

Hello,

Thanks for your post and question. As mentioned in our FAQ, the LFE channel has 10 dB more headroom than other channels. Also, the so-called subwoofer output is not necessarily just an LFE output if one uses the AV receiver for crossover/bass management. The subwoofer output sends a combination of LFE channel + redirected low frequencies from all main channels which will naturally require more swing.

So, to conclude, you can safely plug your 5040A LFE input to your AV device.

Best regards,
