Question about Blessing M400 Marching French Horn In F

1 Answer

Ok, we just picked up a double french horn for my high school. It seems clogged or blocked. He pulled out the slides to find where the stoppage was and found a part of the horn in the later part that was causing it. Is this normal? I know I can ask the store we picked it up from but it is already closed tonight and my son wants to play it. any advise to try?

You haven't described what the part was stuck in or what the part itself was. If the part is stuck in one of the tuning slides I would advise not trying to remove it yourself as it could get stuck worse and replacement parts for French horns are not cheap nor are they easy to obtain. If you do try removing it you risk bending the tubing out of alignment so that the slide won't fit back in and be adjustable. You also risk distorting the shape of the tubing at either end which again has bad consequences. That being said if you do try; try to push the part out gently in the direction you think it entered. Use a flexible cleaning tool like the ones for cleaning trombone slides. It looks like a small diameter plumbers snake with a brush on one end and is often covered in plastic to protect from scratches. Use a gentle tapping action with the cleaner snake against the part inside the tube. If it is still stuck in there try to obtain a ball bearing that will easily roll through the tubing but is larger than the part so that it will not get jammed against the part. Drop it into the tubing. Next drop another ball bearing the same size into the tubing from the same end so that it rests inside the tubing against the first one. Hold the tubing in the hand you use the most with your thumb over the end of the tubing that has the bearings in it. Remember you are trying to remove the part in the direction it entered. Next shake the tubing so that you can feel one bearing hitting the other. Do this gently at first. You are trying to make the impact of the second bearing against the first force the part out of the tubing. Also remember that I recommended against all this in the first place. It took me ten years of experience before I got good at it. This is not normal but can happen. Usually it is a foreign object left loose in the instrument case that is the cause. Make sure that the part wasn't originally soldered to the instrument as it will need to be professionally soldered back on. Here is a link to a professional band instrument tool supplier:http://www.ferreestools.com/ Have a look at the tools and you might get some more ideas. Look in Tool Instructions. Good luck.

I have 4 behringer b 615 d. And 3 of those the horn have stop playing


There are really only two choices. Either the horn amplifier in each cab is blown, or the high frequency horn driver diaphragm is blown. It's easiest to check the diaphragm first. Open up the cabinet so you can get to the horn driver terminals. Put a voltmeter across the terminals and check for continuity. if it shows open, you've found the problem. Open the driver and replace the diaphragm and you're done.. If the horn driver tests good, it's time to take the cabinet into your local electronics repair place to have them check out the amp section.

You have to double check the cable from Ipod to PA system. Most probably the audio out cable from ipod is not correclty fitting the output port of ipod. If you are using any cover for ipod., remove it and check.

Titanium high frequency drivers not working. Is there a fuse in crossover?


i) I believe you can access the fuse by removing the Input Jack Panel.

ii) If fuse is OK, then unscrew the horn unit, take off one speaker wire & measure resistance. If it is open circuit then you can order a replacement horn diaphragm (if you feel confident to fit it to the horn).

No sound in horn when plugged in bi amp connection


The question is whether or not you get any sound from the horn when in full-range. If so, then either the input jack for the horn is defective, or you are not passing the signal. A quick check would be to send the full-range signal (at low volume) to the high-freq input. You should hear the horn work. If not then the connector is defective on the crossover board.

If you get no sound from the horn in any configuration, then the coil is blown for the horn. This can be replaced. It is usually a 22a or 22ti diaphram

Let us know what you find.

Here's some links to manuals for you:http://beallcenter.uci.edu/facility/docs/EON15.pdf andhttp://www.jblproservice.com/pdf/EON-G2%20Series/EON15G2.pdf Hope they give you some info. Second hand prices are always nice but it's buyer beware. I don't have the amplifier schematic but what you are hearing might be some kind of protection circuit for the high frequency driver.
