Yes, I am after for an already made item.

so why ask Do It Yourself website? Jazbo has given you several possible solutions that are all perfectly workable.

Well, I ask this question in diy because I am doing it myself, I don't hire some third party to do it for my, I dont think You make Your own resistors and transistors Yourself either 🙂 Secondly in my opinion workable was only one option, which included passive line level merger. I didn't got answer how to do it or which one to buy so that frequency response would be lower than 20hz. So please don't attack me for my questions 🙂

I use this approach and works fine. You use one channel Non-inverted output and the other channel inverted output to drive the Sub Balanced Input. Or take a look at Behringer equalizer schematics how they implement the SUB out.


L XLR OUT PIN 2 ---- SUB PIN2 (SHUNT 3&1)
R XLR OUT PIN 3 --- SUB PIN3 (SHUNT 2&1)
L&R XLR OUT PIN 1 (GND) --- SUB PIN 1 (GND)

Stealed from another forum. Gearslutz I think, but ... works. I've tried it also with 100m balanced cable to PA speakers on wedding farms / venues..

I use the Behringer MX882 for this. I run line in to two chanels and it has an output that loops straight back out. You can sum the signal to mono and adjust levels from the panel.

A very handy unit that I would be lost without in my hifi/ht set up.
