Can anyone help me on this?

Hi, i'm new on balanced audio and those hi-fi things, can anyone help me on verifying if this circuit would work for muting balanced audio? the XLR-Female receives a balanced low level signal from a XLR electret condenser MIC, the output of the circuit (XLR-Male) goes to the mixer that has phantom power, all 10uf caps are metal film, S1 and S2 are ts5a21366 analog switches that will be driven by a dedicated zero-crossing circuit, but that doesn't matter now, what i really need help is in knowing if the caps will pass through just the signal without any distortion or loss and if disconection will make any noise or pop, i also have the curiosity of knowing if this circuit is optimal for that purpose, thanks for the attention and sorry for the bad english, i'm brazillian.

Why so complicated? I would try a simple mechanical switch that shorts out 2+3 first. (I don't know whether these are readily available as a footswitch in your corner of the world.) Add some series resistance on the microphone side to improve the effect if need be, but don't overdo it (maybe 1-200 ohms max).

Re: your circuit:

TS5A21366 can take a 5.5 V supply max, so let's say Vdd = 5 V typ... that's like 1.76Vrms or +7 dBu, which is a decent level for a mic but still somewhat less than what a number of audio interfaces can take.

The DC voltage between two capacitors is undefined. You'd need some kind of pull-down to Vdd/2. Also, definitely some Schottky clamping diodes to Vdd and GND (see "Phantom Menace" articles).
