REL Sub high level connection possible with ZA3 mono blocks?

[a-tomm]

I have tried to use the low level connection on a REL sub with a couple of devices.
A Blue Sound Node and the Fosi ZA3. In both cases I get almost no volume from the sub.
I reached out to REL about this but still waiting to hear back.

Is it possible to connect the ZA3s in mono block set up to the high level connection on a REL sub?

Hello friend, thank you for reaching out with your concerns. Would you pls check and tell us the input sensitivity of your REL subwoofer?

If possible, you can take a photo of the label on the subwoofer or the specification page on the manual for us.

Although it seems this thread was forgotten about by support I have found the answer for anyone else who might be interested.

The Low Level input is recommended when using a single REL with Monoblock Amplifiers. When integrating a REL Sub-Bass system with Monoblock amplifiers REL recommends using a stereo pair of RELs as left and right subwoofers.

Hi. I have two fosi ZA3 audio amps, which I plan to run in mono configuration. I also own a REL T5/X with both high and low level inputs. Do I need to run a y shaped rca-rca cable with single ended rca at the low level input on the subwoofer end and one of the two RCA ended limbs of the y going to each of the sub outs in each of these ZA3s. ? Or will a single RCA from either one of the monoblock ZA3 to the low level output suffice? Asking since someone had commented that the volume of the sub seemed low when he had connected the sub only to one of the sub outs. Sorry for the trouble and thanks in advance. Need to know what sort of RCA-RCA cable needs to be ordered. Just a single RCA-RCA cable or a single male RCA which splits into A Y with two RCA inputs.
