We go through the specific case of using two stereo systems in dual-source mode on our 1961 and/or 1723 subwoofers.

1961 Subwoofers

Since the 1961 Subwoofers only have a pair of RCA inputs you will need a Stereo to Mono converter to connect both Stereo sources. (here is an example)
This is basically the same as a y-split cable, except it has a resistor in series with each signal of 10kOhms or above to avoid issues on the source side.
Source 1: From the L+R Pre-Outs of your device you go into the Mono converter and connect the single RCA cable to the Input 1 on the subwoofer.
Source 2: Repeat the steps above, just connect it to the Input 2.
It is important to note, that to switch between the Inputs you also will need to use a 12V trigger cable from one of the sources to the subwoofer and set it up in the menu which inputs to activate when the 12V input is active.

1723 Subwoofers

The 1723 Subwoofers are a little more flexible as they have RCA and XLR Inputs.
You will not need a Stereo to Mono converter, but your source maybe requires an RCA to XLR cable or adapter.
Source 1: From the L+R Pre-Outs of your device you go into the RCA Inputs
Source 2: Repeat the steps above, just connect it to the XLR Inputs
It is important to note, that to switch between the Inputs you also will need to use a 12V trigger cable from one of the sources to the subwoofer and set it up in the menu which inputs to activate when the 12V input is active.

Outputs on your subwoofers

The outputs on our subwoofers are direct-passthrough without any degradation in quality.
So if you want to connect a power amp or active speakers you absolutely can.

Frequently asked questions

How do I connect two stereo systems to my 1961 Subwoofer?

You'll need a Stereo to Mono converter to combine both sources. Connect the RCA outputs from your device to the converter, then connect a single RCA cable from the converter to Input 1 and repeat for Input 2.

What do I need for dual-source setup with the 1723 Subwoofer?

The 1723 Subwoofer allows connection via RCA and XLR inputs. You won't need a Stereo to Mono converter, but check if you need an RCA to XLR adapter for your sources.

What should I do to switch inputs on the subwoofers?

Use a 12V trigger cable from one of your sources to the subwoofer and set the menu to activate the appropriate input when the 12V signal is active.

Can I connect a power amp to my subwoofer outputs?

Yes, the outputs on our subwoofers are direct passthroughs, ensuring no degradation in quality when connecting power amps or active speakers.

Are RCA to XLR adapters required for the 1723 Subwoofer setup?

The adapters are not required but may be necessary depending on your source. Ensure compatibility when connecting to the XLR inputs.

Do I need special cables for my 1961 Subwoofer?

Yes, for the 1961 Subwoofer, you will need a Stereo to Mono converter and RCA cabling to connect your sources properly.

What inputs can I use on the 1723 Subwoofer?

You can use either RCA or XLR inputs for dual source connections with the 1723 Subwoofer, providing you with flexibility in your setup.

Will using a 12V trigger affect sound quality?

No, using a 12V trigger for input switching will not affect sound quality; it simply controls which input is active.
