Rated 5 out of 5 by from Great!I bought this about a month ago and it does exactly what I need it to do. It made a big difference compared to the passive crossover I have been using. Although the passive one I was using wasn't tuned very good, this CX3400 makes it quick and easy to get your speakers sounding great.I also replaced my tweeters and bought a new amp for them. Now I am tri-amped.Very much worth it!

Rated 3 out of 5 by from Great for a while, lots of featuresI'll start off with the good. This unit is full of great features for the price. XLR balanced inputs, outputs, 24db professional standard, sound cut buttons for highs lows and mids for R and L speakers (very useful for fine tuning/problem checking/not wanting to bother neighbors with the lows)It has a Horn button to supposedly smooth out the frequency. What it does in fact actually (IMO) make it sound more apparent (harsh). Of course I was trying it with horn loaded super tweeters and not a compression driver (might help compression drivers). Do not use this button if you use domes *not worth your time*.It has a limiter function but it scared me half to death when it activated. I turned it onto a lower setting so I wouldn't damage my speakers with an overpowered amp. However when the limiter function engages it makes a harsh distortion sound (clipping). It was not the amp clipping or the pre-amplified section, just the limiter engaging. In my honest opinion there are much better limiters out there that don't have this type of bad quality to them. In other words practically useless.The low sum works very well for R and L channels. Surprisingly different sound but fairly pleasant as not all music is made to play bass simultaneously with both front speakers (some songs are made this way on purpose) good to use once and a while if you think it will make a difference or like to hear music or movies generally this way.There is a lot more good to say about this unit. However as of right now this unit is irritatingly scrap. It plays, most functions still work. However I am positive something internal (most likely from very inexpensive components) have gone amiss. The left speaker no longer outputs a mid signal. however when the unit warms up or when enough of a preamp voltage is given it finally pops on and works normal. It has even done it to the entire L side before L,M,H. It took me a very long time to diagnose that this crossover was at fault. Surprisingly I haven't used this crossover for very long. I bought it a couple years ago and used for about 3 months with no problems. Take it out from its 2 year resting place and it lasted for only about a month before this started happening. Poor quality componentsThe sound quality is good and if this is your first active crossover you will be astonished at how good it is compared to the muddy/degraded sound of passive crossovers. However as stated in other reviews there are better crossovers than this. My personal opinion and what I am going to do when I get a chance is either buy a digital crossover or make a PC dedicated to output as a digital crossover. Much more control and fine tuning (rendering passive completely obsolete (except for shielding ribbon tweeters (which could turn into expensive fuses)).I would have loved to give this product 4.5 stars. But it just didn't last. I am one of those people who expect products to last for a very long time. 5 months of use is useless to me and a waste of my time. Please save a little more money and get something a little better. DBX, and Rane, has decent reviews in the pro world (though you will be lacking a lot of the extra features this unit offers).I hope this review helps some with their decision and what to expect.PS: music is addictive, play in moderation (whenever your awake basically)

Rated 3 out of 5 by from Looking for Quality Sound? - Not Much Here!When I first received one of these I thought it sounded good. (It was my first active cross-over.) When it went in for repair I picked up a used Rane AC22. It was a night and day difference. The Rane in comparison had a really solid characteristic to its sound that the CX3400 did not have. I received a new CX3400 as a replacement under warranty and re-installed it in the system to verify that it worked. I found its sound unacceptable after I got used to the Rane. I will never use it if I have another option.The CX3400 may have one practical use: Using it with very muddy speakers. It has a very thin even brittle and weak sound to it. I've used it to give a more pleasing and clear perceived sound on a very muddy systems lacking high frequency energy and having excessive low mid energy (A System without an EQ). This is the only scenario I would possible recommend this unit for.

Behringer CX3400 Super-X Pro Crossover 3-Way/4-Way

Can someone tell me please on page 9 in the manual it shows 2way hookup showing only one of the power inputs being used from your source . I have a Behringer Ultragraph Pro and it has 2 out XLR for right and left channel how do I hook it with only 1

Asked by: wildchild
Both inputs are used for stereo two-way operation on this crossover. You may be looking at the midrange outputs which are labeled "Not Used" for this configuration, but both inputs are to be used for stereo two-way playback.

where is the writing subwoofer.How to connect the subwoofer?

Asked by: TAHIRY
This crossover does not have a dedicated subwoofer output, it will have to be wired directly to the mixer outputs.

I'm trying to run the Beringer cx3400 in stereo 3way.  My mixer has a left /right output . The cx3400 does not show left/right inputs. On the backside it shows #14 as an input but none of the diagrams address the other input connector, Left input?

Asked by: Rockyg456
Yes, for some reason they only label one of the inputs but not both. The female connections on the back that are labeled "Input" will both be used for a stereo 3-way setup.

How to Connect a Subwoofer to CX3400?

The manual discussed the Low Sum button routing the low frequencies of both channels to the low output of channel 1, allowing the connection of a sub. Do you use a splitter to split this output signal between the woofer of channel 1 and the sub?
Asked by: hongrn
Lots of buttons & knobs on this crossover--can be intimidating trying to get everything correct. Sub-frequencies usually-but not always-are directed at both channels. Don't use a splitter though {especially a "Y" cord}. The Ch1 & ch2 are electronically summed in this unit to "low out Ch1" for subs. This is a really good unit. Check out the speaker building info sheet on line that PE provides. Excellent reference guide.
