How to Make STEREO and MONO Output on the Taramps PRO 2.4s Audio Processor

For this topic, let’s consider a 4-channel amplifier, which usually has one RCA input for each channel, such as the Taramps TS 400x4, for example. In this project, we will be using 1 pair of speakers for the doors and 1 subwoofer! Throughout this article, we will show how to make the proper connections and channel routing adjustments to achieve the sense of movement in the door speakers, called the STEREO effect, as well as combine the audio signals for our subwoofer, which is called the MONO effect. All of this using our Taramps PRO 2.4s audio processor.

Located in the processor under MAIN MENU => AUDIO => AUDIO ROUTING, this is a simple adjustment. Assuming that INPUT A of the processor is connected directly to the “L” output of the head unit and INPUT B is connected to the “R” output of the head unit, in the channel routing adjustment we select OUT 1 as A, since it will define the left side by being connected to the L output, and OUT 2 as B, defining the right side by being connected to the R output of the head unit.

Below you can find an explanation about these adjustments and a bit about their functionality (it’s worth remembering that A+B is the sum of the signals, which would only be used to obtain a MONO audio signal).

Once this is done, we will have our pair of door speakers on channels 1 and 2 in stereo! Now, in order to connect our subwoofer, which is bridged on channels 3 and 4 of the amplifier, both RCA cables from CH 3 and CH 4 will be connected directly to the two RCA outputs of OUT 3 from the processor, as shown in the image below.

As soon as the connection is made, we will once again use the channel routing adjustment, where the processor’s OUT 3 will be set as A+B, creating a MONO audio signal!
