Recently have connected LF-10 sub to Denon 3801. Sub was tested on another receiver using speaker lines in and works great. When used on this denon receiver, I lose almost all the volume. I have connected it using speaker lines and RCA LFE to LFE/bypass in. Have also increased settings for sub in receiver to +8db with not much improvement. Will a Y adaptor make drastic improvements? or is there something else I can do? Would appreciate all help. Thanks!
