Hi all Audio Circle members.

A small audio project I did and it’s design by Guy 13
and built by an unknown Vietnamese TV repair man.
I say unknown, because it’s someone, that know someone,
that knows me…
What is that black box ?
No, it’s not an airplane black box;
it’s a Passive Control Center.
The small symbols are from left to right top row:
LP/vinyl, FM, TV, Tube amplifier, Aux 1.
Bottom row :
CD, Bluray, aux., Headphone amplifier, Aux 2.
For each input/output jacks, there are two switches,
One for each side (Left/right) to avoid crosstalk.
Back side of the PCC.

Cost of this project including parts and labor.
50 USD.
This is what I really wanted to buy from Wright Audio
(Made in USA)
for 455 USD it much better looking than my black box,
but my PCC at 50 USD does exactly the same job and for less.


Of course when the signal get degraded when it goes thru all those contacts…
But this is the price to pay to avoid plugging and unplugging the cables and eventually break them.
