If the fuse blew, you ARE going to need a lot more than a fuse as the cause is usually internal damage to the amp module and or power supply. Replacing the fuse without repairing the cause USUALLY causes more damage.

When thosse resistors (precharrging of main input filters) burn up there is major damage. The IGBT's are usually gone... replace with APT28GA60BD15... the switching regulator IR2153 is gone... one or more of the 2SA1020-Y and the 2SC2655-Y gate drivers are gone. One or both of the DL4148 speedup diodes for the IGBT gate drives will be gone. The Wirewound ceramic resistors either 10 or 22 ohm 10 watt radials... Use:
This is 20 ohms, however Behringer uses from 10 to 22 ohms in these units... 20 works fine as does 10 ohms. If you have toruble getting schematic let me know.

Voltage readings are normal. I don't know what you mean by dissapator? There are five separate heat sinks on the board. Which is heating? Is this with the load connected? If no load is connected none of the heat sinks should get hot. In regular operation with the fan running they may get warm. If no load and the big one is heating, then one or more of the three terminal regualtors has shorted. If the one with the big diodes near the 70 volt caps is heating, look for shorted surface mounted caps on the bottom of the board near the 70 volt connectors. If the heat sinks with the IGBT switchers are heating, look for a bad gate speedup surface mounted diode. It is unlikely the input diodee heatsink is heating.

Using the mon out and the proper balanced cable follow the instrcutions found in the manual section 61.

Here is a link to the manual.

The word "dissapator is unclear what you mean. If it is a "heat sink" there are FIVE heat sinks on the supply. By not specifying which one we are at a loss to help you.

You have NOT told us what speakers you are using or anything to help us help you. That mixer will produce about 250 watts a side into 8 ohm speakers. That should fill a 30 by 50 foot area. You will need at least 15 inch speakers. Proper mixer setup is important. Look at videos on the subject on YouTube for instructions. Many people use too much high frequency EQ setting. Set the EQ flat to start. Use minimum of reverb to start. Use good quality mics with XLR to XLR cables... none of this Radio Shack or Karaoke quality. Minimum mic cost iis around $90 for decent ones... or about $70 when bought in lots of three or more. For your speakers make sure they are elevated on speaker stands. Use the PFL to solo each channel and set the TRIM level for each as the first step.

Don't have the pin lay out but the power supply is a transformer with two isolated secondaries. The blue & brown leads come from the 20VAC 200mA and the black & white 11VAC @ 800mA windings. I used two doorbell transformers (and a rheostat for the 11VAC section). The reason for two transformers is the secondaries MUST be isolated or something will fry!fb818bb.jpg

You have bigger problems than just the IGBT. I replace that part with part number:


About $6.50 from Digikey.com

You will probably find one or both of the gate speedup diodes blown PN DL4148 surface mounted an one or more of the driver transistors 2SSA1020-Y and 2SC2655-Y blown and usually the IR2153 switching regulator chip. If you haven't blown the 10 ohm ceramic pre-charge resistors you are lucky. Put a 150 watt lamp in series with the power cord to save fuses and parts till it is repaired. If you don't have schematic get back to us.

What is the source of the HCA2400 module? Be very careful if you disconnect the power supply 70 volt cables to discharge the caps before connecting new amp module otherwise you will do some welding with the arc that occurs. You could run the unit with the 70 volt cables pulled at the power supply... leave the other little cables in place. Also be sure to read my tip on Fixya regarding the Channel A hazard with speaker cables. I received an HCA2400 replacement that was wrapped in pink bubble so tight that 5 small electrolytic caps near the audio input cables were broken loose destroying the circuit board. Be sure and check your replacement in this area for damage due to improper shipment. I have repaired some of the HCA2400 that burned up channel A... it is a lot of work to grind out the damaged board and re-insulate and restore circuits with jumpers.

Behringer... | Answered on Aug 23, 2011

The answer is NO... These jacks need to float driving speakers that are NOT grounded in any way. Connection to channel A with a grounded cable will destroy the channel A amp. Use the 1/4 inch MAIN L & R jacks with balanced lines to active speakers. You can drive several active speakers from each of these jacks.

Behringer... | Answered on Aug 17, 2011

Yep... failed channel... most likely "A" channel? There is weak insulation between two layers of conductors on the power amp circuit board that breaks down and blows out the switching transistors for that side... it is usually the rear-most amp. Repair of the board takes GREAT skill in restoring it as the burned area must be ground away and re-insulated and jumpers put in to replace the circuit that has to be removed. The blown components then have to be replaced. One can buy a new HCA2400 amp module for about $155, but delivery takes forever. Also please read my tip on Fixya regarding PMP Behinger powered mixers of a hazard when using Speakon to 1/4 inch speaker cables/adapters.

Behringer... | Answered on Aug 15, 2011

There is no such thing as "MAXIMUM" results... Connect the speakers to the MAIN L and R jacks on the face using 1/4 inch TRS (balanced) interconnect cables. DO NOT USE TS unbalanced cables!!! Also an absolute requirement is that the connected active speakers are powered from the SAME receptacle as this mixer. Yes, this means running extension cords, but unless you can tolerate noise due to ground bounce and damage to your equipment respect this requirement... it isn't in the manuals but is well known among professional sound people. Also please read my tip in regard to a hazard for PMP mixers on Fixya tips regarding Channel A when using 1/4 inch adapters from the Speakon outputs.

Behringer... | Answered on Aug 15, 2011

you have to set three gain controls to pass the FX into the mix. The FX send gain for each input channel, the FX fader which sends the FX mix to the effects unit, and finaly the gain that sends the FX output to the mix. Depending on which effect you choose, some are very subtle.

Behringer... | Answered on Aug 07, 2011

Did you have the same speakers you test with at the store? If not, that is the problem. This unit will generate 400 watts a side when used on 4 ohm speakers, and a little over 200 watts a side with 8 ohm speakers and about 120 watts a side with 16 ohm speakers. For mics, the trim controls will be between 3 o'clock and full right. You set these using the PFL button with loudess vocal such that the indicator does not reach into the clipping. Do this for each channel. ALWAYS use balanced lines where possible. Use of unbalanced cables input results in a 6 Db loss. You will want to run the channel and main faders normally in the 80% range, like between -5 and 0 for BEST signal to noise ratio. There are good videos on You tube about mixer setup. If the speakers were not the ones tested with, your speakers may be the problem... I HOPE they are NOT consumer stereo speakers as you will soon smoke them with this mixer... the consumer speakers are very inefficient and you won't get much sound before blowing them up. If you spent less than $300 for EACH EV speaker new, it is UNLIKELY they are suitable. The suitable ones I found for 12 inch are around $600 each...hopefully these are the ones you have. There are less expensive brands. Frankly, if you want more sound, especially bass, I would go up to 15 inch speakers. These are probably the lowest end price wise to consider: http://www.musiciansfriend.com/pro-audio/behringer-b215xl-15-1000w-passive-pa-speaker Shop around, but stay with PA rated pro speakers as consumer ones just won't take it and eventually fail when used with these amps. ALSO be very careful if you use 1/4 inch speaker plugs as the SLEEVE of the A channel of this amp is the HOT, not the TIP of the jack... short the sleeve to something grounded and it is goodbye amp.

Behringer... | Answered on Aug 01, 2011

Using TRS balanced cables, come from the main outputs L and R on the top of the panel to your external amps. ALSO read my tip on Fixya about hazard of channel A on PMP mixers.

Behringer... | Answered on Jul 11, 2011

If the supply failed I can tell you which parts to replace... and if it failed there may be a failure in the power amp that caused it. You can contact be directely at fredy2 @ aol.com... put Behringer in the subject.

The supply when it fails takes out eleven components including two expensive IGBT transistors. If the rearmost amp fried, add at least four more components and a lot of work carving out burned board and wiring around the blown circuit traces.

Behringer... | Answered on Jul 10, 2011

Please note that the outputs of the MAIN L/R line outs are TRS balanced. If you plug mono plugs into these or connect to mono device you MAY have a problem of grounding out half of the drive internally. ALSO please read my tip on here regarding a polarity hazard of speaker cables of PMP amps if you do NOT have Speakon to Speakon cables, but have Speakon to 1/4 inch cables.

Likely one of the power amps in this has failed If no lights come on the unit now, then the power supply is wiped out as well. It takes about $50 worth of parts and quite a bit of skill and work to restore the unit, including carving out burned board and re-insulating. Likely a feedback occured on that mic and started the whole thing. Supersonic feedback is something most musicians are NOT aware of, but if the feedback is above the range of hearing, the amps can be strained as they may go to maximum power trying to amplify the sound you can;;t even hear. Piezo tweeters are capable of frequencies up to 30KHz.

If this is under warranty exercise it immediately.

Behringer... | Answered on Jul 06, 2011

You don't need to use a ceramic fuse if one's not available. You can also use a glass cartridge fuse as well. Just be sure the rating is the same. Be aware, though, that fuses seldom blow on their own. Usually it's because something else has shorted. So don't be surprised if replacing the fuse only results in another blown fuse. Behringer stuff is notoriously cheap and under-protected, so by the time the fuse blows it's usually more trouble than it's worth trying to fix. But maybe you'll be lucky and it will be something simple. Good luck, and thanks for using Fixya!

The Behringer parts distributor is Fullcompass.com... Lots of luck... I waited six months for a couple pots and capacitors... finally cancelled the order and got scrapped out boards from Ebay to effect the repair.
In regards to the HCA2400 amplifier, I got replacement from FullCompass ($155) BUT Behringer had wrapped anti-static bubble wrap around it so tight it peeled two capacitors off the board and the circuit traces. I now repair the boards myself... it is a lot of work and usually one has to carve out carbonized circuit board where internal arcing has occured and re-insulate and install jumpers to replace the circuit traces. Usually the 9140 transistors are toast and sometimes the 250 as well and a zener gate protection diode. If a cloud of smoke came out, then the 0.03 ohm metering resitor on the bottom is gone as well as two surface mounted transistors that are a part of the current limiter. Most parts are available from online sources... Digikey, Mouser, Allied, Newark, and Avnet.
