Amp 6 documentation notes:
# J2 on PCB rev. 1.0, Place the jumper from J2 to Awake, otherwise Sleep mode.
# J2 on PCB rev. 1.1 + 1.2
* it has 4 pins (sticking up from board), a line around each two pins (a pair)On my board a jumper has been installed on the two pins at the edge of the board. (Differs from representation in top view, where J2 is to back of J1 and thus closer to 2020. On my board, the relative position of J1 & J2 are horizontal--that is they sit left to right.
* the two pins closest to the TA2020 refer to Sleep, an input
* when pins are connected (jumper on/placed), AMP is 'Awake', active/working
* the two pins closest to the output-connections refer to Mute, an input
* when pins are connected (jumper on/placed), AMP is UN-muted, active/working
So one set of pins sport a jumper--leaving me one to solder an on/off mini switch. Is it the case that AMP will only be awake if pins are connected. Also is it true that then AMP will be in mute unless the pins close to connectors are connected.
This all seems counter-intuitive to me: wouldn't you want the AMP's default to be "working" not sleeping, not muted. IOW, designed so that least possible builder intervention is required.
I assume I am missing some important safe guard of equipment.
So bottom line: the pins are arranged differently than the representation on top down view. There is a jumper installed between two pins at edge of board. For the other set of pins, I have a mini-switch: should I solder it to the set of pins behind the one that sits at the edge of the board.
I'd any words of caution or direction.
