Currently putting ferrules on old sins in barrier strips.
You see, I have issues with common Bluetooth speakers. These boom-box descendants might be portable, but they lack stereo output (in which I'm including things like speaker placement et c.) and they don't sound really well.
So, I'm integrating a BT receiver chinesium PCB into my True Multi-Room stereo. Pulled the lines from where I'm placing the receiver into the main equipment rack yesterday, and am currently prepping the connection box barrier strips for soldering same lines. So far today, I've built and laced a loom from the female DB-25 connector that is my standard balancing line amp interface (mimicking the Tascam pinout but the last two channels taking positive and negative voltage to the card). Chinesium card included two header cables to hardwire output. I've cut one and soldered it in, and also made twisted pair tails to the barrier strip. Finally dual supply voltages from the local regulator PCB, also via barrier strip. Tomorrow I'll make a bracket to hold the DB25 and wire up the barrier strips. Until the antenna that's in my Mouser cart arrives, the BT receiver card is to live outside the metal connection box.
In the other end, in the main equipment rack, I'm going to shuffle the inputs to the matrix a bit, so that I have a proper input allocated for this; I can always bodge it, but I've got some improvements planned that will coördinate well with this. Also, this involves soldering in awkward positions. Not looking forward to it. But I designed it myself, so I'll better live with it...
I, in this process, realised I had some ferrulisation opportunities, which I've now taken up.
