How do you hook up behringer xenyx 1832 fx mixer to protools 6.1 on mac

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.

It appears that both these use a 50K pot in the identical circuit and it is UNLIKELY they re-engineered very much so it is likely they use the same pot.

Behringer parts service should be able to tell you.

Behringer uses 4580's in appropriate packaging everywhere. There are 339 comparators for the level indicator area.

The Mackies uses both NJM2068 and NJM4560M

The 2068' are used in most of the low noise areas and the 4560 is used in the 75Hz high pass filter for example.

Yep ! First thing is to eliminate any processing resource "hogs" that **** respources and can cause buffer overruns. Eliminate Antivirus, antispyware, and network communication and wireless network programs running in the background while recording.
Next make sure that ALL equipment is powered from the same receptacle or power source. In your case that should be the mixer and the PC.
Next remember that the condenser mic picks up everything... I have 5 of those mics and seemingly noise free environments turn out to have little things that generate fast rising pulses that you don't notice till they are recorded.
Lastly, the air here is very dry and plain old static electricity is rampart... Lady shuffling her feet was sending pulses through the mic cable at our church. They are NOT audible until they get into the sound system as clicks.
I have found that trying to record directely to a USB stick often has ooverruns and clicks... also burning a CD from stick to the CD results in noise due to buffer underuns. Burn from Hard drive to CD and make sure all the other hog programs are shut off.

You should find pwer supply voltages of +/- 15 volts going to most of the op-amps.
You should find 48 volts for the phantom power source.
You should find 5 volts for the FX DSP or any other logic circuits.
You should find a +12 volt.

Here is a manual close to your unit (yours is an expansion of it):
