how to change components in an audio chain

[massiolivo]

Hi dude, I need a piece of advice:

I would like to create an audio channel strip (preamp-equalizer-compressor) all made by me and I would like to be able to reverse the order of the components (eq and comp, the preamp must always be at the beginning of the chain) can I do it with a switch? (pos1=EQ —> COMP pos2=COMP —> EQ) and if it’s not possible with a switch how can I do it?
I was thinking about relays but i don’t know how to connect them, do you may have any schematic?
Instead I would like to avoid digital switches or mosfets.

I remind you that the signals are balanced so in addition to the ground there is a positive and a negative signal in input and output from eq and comp.

Thanks a lot in advance!

Two inputs and two outputs, left and right, balanced signals.
That counts up to an eight pole changeover switch.
Use a rotary for easy connecting/soldering.
Grounds stay unswitched.

as I assumed, can you help me make the schematic please? I don't know how to do it! Really thanks for the answer!!

The drawing takes up an hour, and I'm busy with other things.


If you want 2 xlr's input and 2 xlr's output, a 12-pole swith is needed (8-pole when separated xlr's).
Start thinking mono unbalanced:
- each processing block has a 1-pole switch between xlr in and output of 'other' block
- output xlr has a 1-pole switch between the output of the blocks
- the switches are coupled, when the input goes to block A, the output comes from block B &vv
- in total 3-pole switch needed

Stereo unbalanced: everything times two: 6-pole switch
Stereo balanced: everything times two: 12-pole switch


Draw it, good practise.

Mono balanced is like stereo unbalanced...so I need 6 pole-2pos swith i think, i try to draw all down

How about this

@epicyclic

Thank you very much!!!!!!!!!

Or get a patch bay, for even greater flexibility.

How about this

Your penmanship is eerily similar to mine. If I was recovering from amnesia and someone showed me that and told me I wrote it, I would have to believe them.

Spooky

You can better swap everything: it is bettter to switch the low impedance output then the high impedance inputs. But in general both epicyclic & cogitech have made the right drawing together.

What you want is all realized in a small mixer like Yamaha, good quality and at affordable prices
