#Behringer 802 manual manual#

IN SHORT: to power a Behringer Xenyx mixer, it appears that all you need is a 16VAC >1A transformer between the TOP pin and either the LEFT or RIGHT pins of the mini-DIN plug going into the mixer. So would my simple 16VAC PS still work if I switched the wires to be between the TOP and LEFT pins? And -yup, you guessed it вЂ“ it did indeed. The next test: looking at the voltages measured on the MXUе…ѓ and how itвЂ™s speced, it looks like the LEFT and RIGHT pins are symmetrical, equal connections. While there IS a 3VAC lead in the stock PS, and it IS connected to the mixer, it doesnвЂ™t seem necessary for anythingвЂ¦ (?) But IвЂ™ve got a couple 16VAC supplies in the junk both, andвЂ¦ bingo spanning the TOP and RIGHT pins does indeed power the mixer, not just the channel mix electronics, but the phantom power as well. Which posed this question to me: could I power the 502 with just 16VAC between TOP and RIGHT pins? I donвЂ™t want to buy a center tapped 36V transformer, as for what that would cost me, I might as well just buy the MXUе…ѓ. The pins in the connector, looking at the plug on the end of the power cable from the front: These meters always seem to read voltage over the listed spec, so BLUE to YELLOW is the speced 16VAC. The AC voltages between the pins read as follows with my cheap Harbpr Freight multimeter: ThereвЂ™s nothing inside but the transformer coil itself which has 3 leads: BLUE, RED and YELLOW. So I decided to take it apart and check the wiring. IвЂ™m just reporting that via some circuitry vooodoo, this one works as well: IвЂ™m not doubting that that the MXUе…ѓ works for all the models listed. But I also have a Xenyx 1002B that still has the PS that came with it. If you read this, please leave a thanks, share the luv! рџ™‚ Noting item 4 above, my guess is a similarly connected 24 volt DC supply might possibly power one of these machines, and bypass all that circuitry that makes things hot.ДҐ. So my guess is that there is a circuit which creates the phantom power that accounts for almost all of the heat generated by these little mixers. The funny thing is that the 2nd mixer works beautifully, and I tried ALL its functions, except phantom power, and the interesting thing is that the 2nd mixerвЂ™s heatsink was very very cool. I used only two wires, one for positive, other for negative. The reading on the first pre-amp was about 23 or 24 volts DC. It was a simple matter of connecting the power supply line from one mixerвЂ™s preamp to the same place on the other mixer. I was tired of a mixer with only two pre-amps so I connected the two mixers together using only one power supply. When I say вЂњseemed to functionвЂќ, it seemed to mix all channels to the main mix bus, with no problems, and no noticeable distortion.ДЈ. My guess is the other two pins are for the phantom supply. One day I plugged an 18 Volt AC supply into two pins, and the Eurorack seemed to function. With a Eurorack with no power supply, I have great interest in creating one. There are many variations of power supplies out there, some say 3V, others leave it off, some say 13WДЈ. There really is no 3V rail that is used on the power supplyДў. Here are a few weird things I have noticed.ДЎ.

Here is what the user manual to the Xenyx 802 says about the Power supply:ДЄdapter: Behringer PSU MX3UL (yes, this is not a typo) I own both a Eurorack UB802 and a Behringer Xenyx 802, and the PSU which is pictured above, says on it MXUе…ѓ (this is not a typo), is from the Xenyx 802, and works on either mixer. The voltages are :left pin to center pin: 20.7VAC My power supply came with my Xenyx802 and it is labeled вЂњEurorack power supplyвЂќ. These are AC voltages! Also note, that the power supply says something about a 3V 100 mA output, but there is absolutely no evidence of it. My PSU measurements are in AC volts, there is a negligible voltage between the metal connector and any pin, and I checked for DC voltages in all combinations, and found none. Here are the pinouts with diagram and voltages. Here are the specs: USA/Canada model: 18.5VACX2 250mA.
