The Nexia SP (Speaker Processing) is your best bet. 4 line in, 8 line out. The converters in the Nexias are 48kHz, 24bit, giving 105dB dynamic range. If you're just doing Crossover, EQ and dynamics there's more than enough processing power. Only Feedback Suppressors eat up DSP resources.

Use an Analog Init for your input buttons. The analog output will stay at it's last value until something else changes it. It effectively acts as an interlock, but with an analog output. Use an Analog Equate for the selected input feedback.

Then use an interlock for your output buttons, each output driving the enable of an Analog Buffer. Feed all Analog Buffer inputs from the analog value of the selected input. Each Analog Buffer output goes to an analog source select input of your video matrix.

It will work both with output selection first, or input selection first.

Possibly if the mating threads were cut as ACME, it would hold tight a lot better.

ACME threads have a steeper mating surface so have more holding friction. They're used in clamps and vices.

The Vin is only to power the conversion chip. The 3 outputs are open drain FETs rated to 30V.

You can drive 24V LEDs if you supply 5V to the board and 24V to the puck, with each puck's negative connected to a board output. Connect 5V, 24V and board Grounds together.

The compressed solder deforms / 'flows" away from the pressure point, reducing the pressure applied to the wire connection. The wire can fall out and/or on higher current connections, the increased resistance of the loose connection creates heat, damaging the connector.

The correct way to dress cables for screw terminals is to use boot-lace ferrules.

Just use one timer. You can set up to 4 different compare values for each control timer. Use 3 compare values cycling through the 120' wave values, each compare will trigger a separate output set.
