Read the manuals for both the mixer and the active speakers. If you do not have the manuals, download them from the manufacturers websites. If you don't know hw to use equipment, don't buy it.
SOURCE: Need Behringer Eurorack mixer power supply connector
Those were used for mic connectors at one time,,, they are related to the Amp 91-MC3F family of connectors and those are out of production and they are demanding $20 to $50 for one connector.
That is a ridiculous price and I would be tempted to swap out the connector for a more available design.
On eBay item 250401122616 is one but they want $13 pus $11 shipping which is a rip off.
These were used on some OLD CD radio mics.
SOURCE: my effects on the behringer djx 700 dj mixer stop working how
This is a wild educated guess.
I repaired a Behringer guitar amp that had a DSP effects in it (BX1200 I believe).
The effects were on a seperate board and the board had its own 5 volt power supply. The filter capacitor for the 5 volt power on the board was UNDERSIZED and it had degraded causing the 5 volts to drop out of regulation, dipping to 4 volts. This caused the DSP effects to fail.
YOUR device MAY use the same DSP OR design.
Check the 5 volt power with an OSCILLOSCOPE to look for dips below the 5 volt operating point that occur at 120 HZ.
SOURCE: No Volume oe sound coming out of speakers
try connecting speakers to another sound source or if you have access to a ohm meter, check impedance of speakers, should measure 4~8 ohms.
SOURCE: How do I connect my behringer mixer desk to
The first thing to do is to swap teh L & R INPUTS to the amplifier. Did the speaker that works change?
If som the problem is with the setting of the mixer deck. If it did not change, then the problem is with your speaker wiring of the dead speaker, the speaker itself, or that side of the amp.
If the working speaker did swap, that means problem is with the mixer. The question then becomes how are you connecting to the mixer. You should be using TRS 1/4 inch connectors or preferably XLR from the MAIN outputs. These are balanced outputs connections.
If the inputs are from one of the mono inputs, the PAN control for that channel will control how much goes to each speaker... If at center, both will get same signal.
There are so many possibilities that I can't evaluate them until you try the test to find if it is problem of the amp or the mixer that I have given you to try.
SOURCE: Behringer XENYX 1622FX, won't power on. Phantom power works(?)
After reviewing the schematic, I don't understand how the Phantom power can REMAIN on with the power switch off... this CANNOT occur except for what energy is left in the 48 volt supply filter cap... This might last for minutes after the fuse went... UNLESS you have devices connected which are backfeeding the 48 volts. (which would be a disaster)
The 48 volts, +/- 12 volts and +/- 15 volts and the +5 volts ALL come from the SAME switching power supply. I suspect one of the filter caps went or the primary switching regulator a TDP245Y chip.
You should ONLY work on the line side of this using an ISOLATION transformer since the line side has lethal voltages.
To do testing, one replaces the fuse and puts a 60 Watt light bulb in series with the hot side of the inout line. The lamp "acts" as a resetable fuse and limits the current for testing. When all is well again, the lamp will remain out with the power flowing through it.
The D1 diode bridge and C7 input rectifier and filter are first things to check. You can do those with an ohmmeter.
I will caution you to ALWAYS power any and all equipment from the SAME power source. Plugging in devices from across the room will set up ground loops and any ground fault will fry equipment.
