Ok so i get in the car drive 10 miles round trip to the radio shack (cause it's 5 miles up the road and 5 miles back).

Your correct if you are all set up with a workbench and tools but not everyone is. This is as simple as screwing in a lightbulb.

You're going to pay a heftier fee for the factory supply. This is a typical off-the-shelf readily available power supply transformer. These transformers are available from companies like Newark Electronics, Digi-Key and others. Thankfully, this kind of simple AC supply, only requires a simple transformer and the connectors you need. Of course it's always desirable to have the company supplied unit. Even if it only works off of an 18 V supply. I would be surprised if that mixer does not offer Phantom power. These DC to DC up-converters have come into play and become quite popular in recent years more so than in the past. No worry about polarity of the 18 V supply side because it's AC.Īssuming that the power supply has plenty of current to deliver, the internal power supply circuitry may also include DC to DC up-converters to create 48 V DC, low current, for the Phantom power needed for condenser microphones. So it only requires a simple power transformer to convert 110 V AC to 18 V AC and you'll be up and running.

Yeah Boswell, I checked the specs on that mixer power supply. 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.
