The supply will be similar to that in the 1222. Download a schematic here. Look at the SPUS2 portion of the compressed file.


There are several voltages present.

Has somebody spilled liquid into the unit? Are you using XLR to XLR mic cables? If using condenser mics you need Phantom power on else NOT.

If the faders are noisy, use CRC226 in them. You can get that at Home Depot in the electrical dept.

NEVER use contact cleaner such as Deox.it or BlueShower in faders... it wrecks them

Try this link:


On page 11 is the power supply. The TIP31 (T1) is the regulator for the +15 volt rail. The TIP31 is connected as a Darlington with a BC846 (shown on the schematic as "846"). This is a surface mounted tiny transistor.

NOTE: This regulator is NOT a voltage regulator but is actually an ACTIVE ripple filter consisting of the 2.2K resistor (R6) bypassed by the capacitor C4 (100mfd/25v). R8 (120 ohm) serves as a parasitic suppressor and base surge current limiter for the BC846 transistor (T4).

Here is a link to a schematic that should be close to yours. A lot of these just have more channels but circuitry is the same.


This is a zipped file. The schematic including their typical EQ is on the first file of the zip. The power supply is the last.

At the site, click on the brownish button with a down arrow to download. You will need to unzip the files or extract them using winzip or other decompressing SW.

Hi, It is not on selector knob, but it could be on capacitor(s). As stabilizer capacitor has role to maintenance the good power feeds to system. Please check it then.

Read and understand the manual. You might also find a video on YouTube explaining part of this.

There are a number of configurations for a mixer like the 1832, the most common are PA system and Recording system. There are Main output jacks which carry the mix as summed in the main faders. These in a PA system would feed the pa amplifiers which drive the house speaker system for the audience. These connectors are XLR 3 pin type on the rear, intended for professional pa amplifiers which use balanced +4dbv line input level. Amplifier which have 3 pin XLR connectors for input signals can accept that high level signal. For home style HiFi amplifiers, the signal level is nominally -10DBv and balanced or unbalanced signal lines with 1/4in diameter phone plugs which are connected to the mixer by way of a second set of Main output connectors which are 1/4in phone jacks. Use whichever amplifier input level your amp has.
If you are not using it as a main PA house mixer, but using it for recording, the main output connectors go to a 2 channel recorder or computer sound card recorder. The power amp and your monitor speakers are connected to the connectors labeled "Control Room" (CTRL Rm). These output are useful for recording because the signal through the mixer can be monitored from several buses, Solo, main mix, selected by buttons provided. The buttons only affect the signal heard through the control room monitors, and not the main output which only sees the main mix so selecting "solo" does not interrupt the signal going to the recorder while the engineer in the control can be checking other signal paths through the board.

Right next to the master leds there is a knob directly right of that is a 3 way push button switch push in cd/tape and the level is off of the knob. Good Luck, Cody J.

In the control panel, "sounds and audio devices" under the "voice tab" make sure the INPUT is set to the Xenyx device.

hello, I have a behringer 1832. the issue I have is that the right channel is out all together. both subs work. it is only the right main. do these things have some sort of mono switch that I don't know about?

Behringer Xenyx... | Answered on Nov 21, 2010

Make sure Sonar is set to use the Xenyx for the clock in the audio options pull down menu. It often defaults to your PC soundboard.

Behringer Xenyx... | Answered on Sep 23, 2010

The main mix controls ALL outputs simultaneously.

The mic channels are controlled individually by the sliders.

It sounds like you are on the verge of feedback where the mics are picking up the PA speakers.

Make sure you have loaded the support SW and make sure you have disabled ECHO as the mics may be looping back through the computer causing the rattle.

Behringer Xenyx... | Answered on Sep 07, 2010

I don't think you require a part number for your mixer, ring the company and tell them what model you have and I'm sure they will be able to assist you in regards to your volume slider.
