you may use a DPDT switch for each SUT, instead of a 3PDT.....

Smart.... Haha

by always take the Common 7...........n 4............ less wiring... seem to be less wiring too...with just one pair of RCA... ..why i want to use 2 pairs? ..why...i lost my mind..haha.. .made not much sense..if i am going to use it with just connect to one MC / table

if i connect to 2 table... may make sense for 3PDT ..........

make up my mind............

this switch is used for gain control (& impedance matching). you cannot combine gain control (& impedance matching) and sources selection in a single switch. i suppose you want to control gain and select sources (turntables) independently.

the DPDT switch is used for mono operation. for stereo, you will need a 4PDT switch. if it's rotary type, you may choose 2-pole,2-way switch for mono, or 4-pole,2-way switch for stereo. in general, high quality 6-way switch is readily available and can be used as well.

Haha trying to shoot a few birds.. With some stupid thinking...


Yes the core aim is to select in out impedence fro. Those 2 series or parallel primary

Is ok to use one on each side...

It is indeed nicer for only having one switch for both.. As u have some sort suggestion to
Haha

There is quite limited Ted choices for rotorery switch or I has not look enough..

But should having 2 layer of control structure.. One for sources and one of impedance

Thxx
