Now to make up some wires.<\/figcaption><\/figure>\n\n\n\n

Think my custom single ribbon cable caused an input board to blow up (just oscillated), so switched to three cable solution with a couple of them supporting two plugs. This was even after testing the ribbon cable positively and negatively (wires not merged). Only wired one channel so only one replacement input buffer board was required, after testing the 1ET400A module was okay.<\/figcaption><\/figure>\n\n\n\n

Needed to find what the voltage settings were on the 4ch for stand-by 0.86v and power-on 2.00v power switch light. Replaced the trigger socket on the 4ch whilst it was open to a mono type.<\/figcaption><\/figure>\n\n\n\n

Test all channels and trigger ports. <\/p>\n\n\n\n

All okay.<\/p>\n\n\n\n

Application Note:<\/strong> The PSU used here is a Hypex\u00a0SMPS3kA400 2 x 65 VDC 3000 Watt Switch Mode Power Supply, which does not feature the 2-quadrant operation that others in the range do. Half bridge modules like the Eigentakt module that are providing frequency range below 100Hz need a workaround of reversing phase for half of the modules. (i.e. swapping the input +\/- of the input buffer and then swapping the speaker output on two of the modules – not shown in the above images).<\/p>\n\n\n\n

This is 5 channel device so one module can’t be matched with a reverse phase so is relying on the high capacitors on the PSU > 1000uF. <\/p>\n","protected":false},"excerpt":{"rendered":"
