The answer to the question if you needed the extra active box between mixer and crossover would be yes, if the downstream equipment (crossover) wasn't equipped with a boost drive or conversion switch. You wouldn't need an active box with the dBx crossover (223) mentionned.
Basically, if your equipment has a 'low' (-10dB) output you may want to use a 'preamplifier' (ie. active box) to get the levels to a point where it will drive correctly the amp. And yes, if you used an electronic crossover, such as the dBx 223, you may be able to boost your mixer signal to your preferred listening level. Furthermore, other types of electronic equipment such as eqs, other xovers, may have a selectable -10, +4 dB sensitivity switch for correct input or output voltage conversions.
Hello and welcome kapou,
Note: System Architect has been superceded by Audio Architect. AA includes the Netsetter application that should help resolve most network conflicts.
But you have USB! I don't know how well it can connect through wifi. I would suggest, initially, to test the connectivity directly from the computer through the USB port to the amplifier. If the connection can be established then at least you know that it can connect and it is now a matter of hardware.
Have a great day!
Probably, you have filter cap issues (output module); You will find broken solder connections on the cap leads. This will cause premature failure of the filter caps. If the caps have leaked or domed, I recommend the replacement of the (4) filter caps, (2 x 8200uF, 110V for each output module); Also, meticulously resolder any potentially cold solder connection on both output modules, resolder jacks and mounts on the i/p board, led components on the display board, retighten output binding posts (remove and reinstall binding posts), and verify and resolder all power connectors.
Furthermore, replace the two caps, C23 and C24 (100uF 25V), in the SMPS negative supply (-13V) section. And don't forget to adjust the ULOL (under lap/over lap) settings!
