    Input Selector Switch or Relay Controlled Selector?

    Post by Jedidiah on Wed Oct 03, 2018 7:51 pm


    I see that some of the SP's had the option for relayed controlled input selection.

    I was thinking about doing this on my SP14, is there a reason that it doesn't make it in some of the custom builds I have seen?
    I can't imagine there be a HUGE difference in sound from running the wires all over the chassis and back vs just an inch or two from the inputs to the controller..

    Thank you in advance for you input!

    (long time reader first time posting so thank you to all that post here as i have been reading lots over the years)

    the only advantage of an input relay switcher is using alot less wire or cable
    and if you use one that has remote control for switching if you're too lazy to get out of your seat

    Here's my switcher  ....and it's dead quiet. This is also where I have my stepped attenuator.

    Switch Positions:
    1 Left & right outputs shunted to Gnd (Mute)
    2 CD deck
    3 DAC / Rpi Server
    4 Line feed from recording suite
    5 Rear Aux input
    6 Front Aux input

    another option is to use a shaft to connect the knob on the front panel to the selector switch at the rear panel, but this would require a dedicated pcb to which the selector switch and RCA sockets are mounted to.
    If you are interested in this type of setup, 'pm' me.

    Would certainly make for a clean build.   Does this mean you are into making PCBs professionally? if so I may need your services from time to time.

    I get them made for my custom builds and I do have the pcb in question, again 'pm' me if you are interested in more details etc..
