@jtcf I just don’t see the reasoning in using a Y adapter if I could just use a straight cable from the source to the Sub. Is the adapter going to give me a better connection or signal in some way than a straight cable? I would still need to spend more because of the cost of the adapter and also an extra set of cables as well. And I figure it could potentially introduce more adapter related issues unnecessarily.
Sub wiring help, high level speaker terminal to RCA line level Sub inputs
I just received a new Rhythmic L12 sub, and surprisingly did not realize it only has RCA line level inputs. I had purchased it thinking it also had high level speaker inputs to connect it directly to the speaker posts on my power amp.
I have a Cambridge CXNv2 connected to a Schiit Aegir Power Amp through the line level RCA. Now, the CXN does have an additional balanced XLR out, but I can only connect the Schiit Aegir through RCA.
So these are my options and questions:
1. Connect the Power Amp to the Sub using a custom cable with speaker terminals on one end and RCA on the other end.
2. CXN XLR --> Power Amp RCA, and CXN RCA --> Sub RCA
3. CXN RCA --> Power Amp RCA, and CXN XLR --> Sub RCA
4. Return the Rhythmic and get an SVS SB1000 with high level speaker inputs.
In this case I’m not sure what the positives and negatives are about trying to connect the Sub via speaker terminals or RCA line level on the CXN. Or is it even advisable to use a cable that goes from the speaker terminals to the RCA line level inputs of the Sub?
Appreciate any help!

I’ve done some more reading and found using an XLR to RCA cable is a bad idea. Mainly because to make the cable the XLR (-) lead is shorted to the ground lead on the RCA side, which could cause feedback issues and potential damage, so those options are out. https://forum.audiogon.com/discussions/cd-player-xlr-output-buzzing So my options are then what yogiboy and jtcf suggested to use an RCA Y-splitter, or my original though of using a speaker terminal to RCA cable. |
rhern213, sorry for the bad advice above. I've actually done this. The simplest solution is a Line Out Converter or LOC https://www.parts-express.com/stinger-sgn111-30-watt-fixed-line-out-converter--268-482 This is simply a couple of resistors between the wire inputs and RCA outputs. One resistor drops the amplifiers output voltage down to line level, the other provides the impedance load to whatever the output component needs- the sub in your case. My integrated amp didn't have a pre-out and so when my new sub amp had like yours only line-level inputs I researched this to death before modding my amp. In my case I am comfortable modding and installed the parts inside my amp. It does look better that way. Electrically however it is identical to the above LOC, which I'm sure you will find a whole lot easier to use. |
Why not send it back for a replacement with Rythmik subs that comes with high level speaker input. I see no reason to apply ‘band-aid’ solutions being suggested by Rythmik fanboys. Or you can excercise Option 4. IMO, using high level input connectors offers the best possible integration with your mains speakers. “The high-level input is designed to accept the stereo (two-channel) signals from the speaker terminals of your receiver, integrated amplifier, and basic amplifiers. This has the advantage of ensuring that your subwoofer receives exactly the same signal as the main speakers, which means that the character of the bass from the main system is carried forward into the Sub-Bass System”. |
IMO, using high level input connectors offers the best possible integration with your mains speakers. Okay so here's the thing. If you look at the schematic for subs with high level input connectors, the circuit is exactly the same as the LOC described above. Exact. Same.Thing. The only difference is the circuit is inside the sub, as opposed to being in the LOC. But wherever it is located, it is the exact same thing. |
