Decware ZSB please help

A switch box without a switch? I’m not sure why I would do that.

First, you have the unit, and a factory schematic would be wonderful, but again, YOU have the unit.. Draw one up and I’d be more that happy to draw lines for you and add a big ol honkin switch..

Put a big knife edge switch on top of the box made of polished and varnished copper.

Add a little turn of the century flair to the Zen, maybe Vulcan "My thought to your thoughts, my mind to you mind". :-)

Time to feed the chickens..

OK OP my only question; do you have 2 (two) RCA inputs or one?

If you have only one pair or L/R RCAs add a second set. Cut the wires and leave pig tails on the original switch 1/2 - 1" long, from the input RCAs

DON’T cut them to short.

You need THREE dual poles and a two position toggle switch. The center 2 poles is the feed for the two pigtsils you left on the original switch.

The other two pairs of RCAs (L/R) goes to either side of the feed wire poles (center).

You can have an OFF position by adding a 3rd center throw or it could combined both A and B positions (not usually a good idea)

So
A or B
A off B
A both B

1 and 4 to one set of RCAs (A)
2 and 5 to the pig tails
3 and 6 to the other RCAs (B)

I still don't see how to get to the "4 amps" or 4 outputs without a bunch of cable splitting. 

Use the Schiit and Decware together and only use one input on the Decware and it's 4 outs.

OR draw your own schematic and solder away on just the Decware..

A preamp would have fixed it all for the inputs and output to a single  input on the Decware and use its 4 outputs. Simpler yet..
