Dual Source With Two Stereo Systems

In addition to our two guides for dual-source;

1961 Amplifier settings – Best practice for Dual Source

1723 Amplifier settings – Best practice for Dual Source

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.
