Hook up diagraph equalizer to av recover onkyo

You need a RCA sub-woofer cable (analog mono) to connect between the receiver's sub-woofer Pre Out and the sub-woofer. This cable has a single RCA plug at each end of the cable. The cable is somewhat thicker than some audio RCA cables. You can use any RCA cable temporarily.

The manual for the HT-R758 is available from Onkyo here: https://onkyousa.com/ht-r758 . The current link to the manual is https://assets.onkyo-av.com/product-manuals/HT-S6500_English_2022-11-02-204020_ivkn.pdf?v=1667421620 . See page EN-13 (page 13 of the PDF) for connecting to the subwoofer. The original package came with a 10' RCA sub-woofer cable, see page EN-1 (page 81 of the PDF) for the speaker list.

I hope this helps.

The TX 8555 can drive the speakers directly but if you want to use the equalizer then you need to add an amplifier to the system so that you can feed the pre-amp connections from the TX8555 through the equalizer and then into the amplifier to drive the speakers. This is because the TX 8555 doesn't have a loop back function for monitoring recordings.

"Onkyo TX-NR801 AV receiver using a coaxial digital cable but cannot get sound from the AV receiver." In onkyo amp, choose DVD, then in digital audio settings choose coax1. Then enter. In blu ray player, digital output selection choose auto or bitstream .

Either take a picture of the rear connections so we can determine the setup or describe what connections are available!
