cable testing tonight
Hello
I plan to make a test tonight with my self-made snake.
It has cat-5 and powercable wrapped around each once about every 20cm/8inch. Total lenght about 20 meters/65 feet
I have in mind two tests - both with cable fully coiled AND fully stretched - snake reel is metal.
I´ll connect two S16 and X32.
I will power S16 x32 separate from snake power-cable in order to avoid any of test-induced stuff to get into system via S16 6 X32 PSU:s
Also I think that it might be better to have 100% of "dirty" power than 50/50 "dirty/clean"
I will leave all inputs open with minimum gain in order to not bring anything to hear into system.
I will open all faders up to 0 - channels and master.
For reference I will listen to master output without anything connected to snake power cable - and measure result, if I can.
Test 1 Run about 6A lamp load with analog dimmerpack to "see" / hear if it induces anything into CAT - tweaking dimmer to get some noise.
Test 2 ( this one I learned at Turck Multiprox MN )
connect a power-relay / contactor / toroid x-former as load - using a rough file and cheap voltmeter-probe as switch - swiping probe along
file produces very uneven connections, that causes large spikes into power cable. ( feed power cable in normal outlet - no dimmer. )
we used to test industrial proximity switces like this - it was much more difficult test than the "industry standard" those days.
Test 3 If anybody has suggestions of some other things, I might try do that as well, while at it.
I´ll start testing in about 4 hours after posting this - so hurry with your ideas.
