@millercarbon. Thanks BTW. Stupid question: is there a decent grade LOC unit that you recommend? Also, a few I saw online have a bunch of color coded wires sticking out. Which wires connect to the R/L of the amp speaker output.
Hooking up my JL sub
Folks - I need a little help. Trying to figure out best possible way to connect my JL Audio F112 sub to my Marantz AV7005 processor/preamp.
Signal is coming from Benchmark DAC 1 - yes I know it’s a preamp and yes I love the sound directly from it - except that there is no remote volume control and I am lazy.
Passing signal to my Marantz in Pure Direct mode cuts the signal to the subwoofer. Can I use a RCA Y splitter and pass one signal to Marantz and the other to JL audio?

Not if you hook up to a preamp that has a crossover adjustment. Last night I played around and was able to shut off all equalization and Audessy setup in Marantz and manually adjust the crossover for the front R/L to 80hz. Also able to adjust the bass delay to 12ms and both my sub and speakers are now singing sweetly. LOC connection does not provide you with this configuration as a matter to fact gives you double bass. |
I am still a little confused and any help will be great. Willing to try what @millercarbon suggested. Just got 2 questions: 1. If I connect using LOC most on the market are for car audio and says max RMS 50W. Is that a concern. 2. Once I successfully connect the subs using LOC and adjust the crossover on the sub - can I have another XLR connection from my Marantz AV to use as LFE for movies? Will dual setup work? Thanks |
@ozzy Probably the easiest and best way would be to use either an electronic crossover, or just simply use a y adapter. One end goes to the main amp then speakers, the other goes to sub. You can adjust the sub for the proper low level point, What’s the y adapter look like? Sorry a noob here. Will this work? https://www.crutchfield.com/S-DH5rbymUfUX/g_721/Line-Out-Converters.html |
@imhififan Benchmark DAC 1 has both unbalanced and balanced outputs, the unbalanced rca output connect to Marantz AV7005, balanced xlr output connect to JL F112 sub xlr input directly or via a switcher, so no 'y' cable/adapter needed. That will not work - if Marantz is the preamp the signal will generate from Marantz to the sub. |
