![]() And I'm wondering how they obtained +48 for the Phantom power? So they are likely using a DC to DC up converter? So I really question that rating of 18 V? Maybe you should pick up a manual that includes a schematic? They can be helpful. The only thing you have to find out is whether it required 18 V of DC or 18 V of AC? One will be the lucky and the other will take it out forever LOL. Sometimes you find these on other mixers with ground, +48, +15, -15. Pin 1, is ground and Pin 4, was 12 V of positive DC. 4 pin XLR's were regularly used for 12 V power supply connectors for video cameras. Sometimes it requires a modification to a 4 or 5 pin, XLR connector which are much easier to find in comparison to some of those bizarre Taiwanese connectors. Everything available at RadioShack.įrequently it's hard to find specialized connectors for these power supplies to your mixer. You build it into an aluminum project box. And then you have a power supply costing about $25. ![]() ![]() A couple of large filter capacitors and an National Semiconductor, Texas Instrument, etc., 18 V regulator rated at least at 1 amp or more. All you need is a 110-24 V transformer, rated for 1.5/2 amps. On the other hand, it's no big deal to make your own power supply. ![]()
