Professional 2/3 Way Stereo/4 Way Mono Crossover with XLR Input and Output, Stereo Audio Sound Processing for PA System with Subwoofer

Excelente

Used this for a restaurant install that had a zone with a subwoofer. Everything worked as it should. No noise.

Rack mount analog crossover with adjustment knobs for crossover points. Note that if you attempt to use this as a 4-way crossover you will need two of these units.The ideal crossover points depend on driver specs, but general recommendations are:• 2-Way: ~1.5 kHz – 3 kHz• 3-Way: ~300 Hz and ~3 kHz• 4-Way: ~80 Hz, ~500 Hz, and ~4 kHzThere’s a low pass filter which can cut off low frequencies below 40hz which is handy if your woofer can’t handle the lows very well. 40hz is still going to thump the chest though.There’s overall gain, and individual gains to SPL match the drivers. Because these are knobs, it’s a bit rough to set the crossover points to exact values so having some sort of RTA or graph of the frequency response would be helpful to achieve flatness.The phase inverse is an option that could be used for tinkering. Note this is a crossover only so you’ll need amplifiers and drivers.Knobs feel smooth, LEDs indicate active elements, and connectors are solid.

This unknown company makes some quality products and this one is no exception. I use it to separate the zone for the sub woofer and it provides better quality with only the frequencies desired going to the sub woofer.The lights can be dimmed down a little though. I'm going to try putting some tint over mine.

This is now my second piece of equipment from Mizisnr that I've picked up from Amazon and I have to say that I've been nothing but surprised by how well this Unknown Brand Name Performs against popular brands that we're typically used to!The Crossover chassis of this unit is metal and quite sturdy! This unit is great for Live Concert or DJ Applications as it takes the original signal and allows you to split it anywhere from Two to Four Ways depending on the complexity and range of your Live Sound Reinforcement Setup!You have a variety of options for splitting a signal such as Two Ways which means your High Signal will go to one set of Speakers and Your Low Frequency Bass signals will go to another! You have the Three Way Option which allows you to Split a signal let's say Highs, Mids & Lows! In addition, you have the option of splitting a signal Four Ways which means you can split out Highs, High Mids, Mid Lows and Lows to different sets of speakers depending on your setup!In our live sound studio our setup accommodates a Three Way Crossover Split! Therefore, I simply swapped out the Crossover that we typically use with this unit! All I can say is there was no noticeable difference between the brand named Crossover that we typically use and this unit! Both units worked excellently!In conclusion, this unit from Mizisnr in my opinion has almost identical performance to more expensive brand named units! Therefore I'm rating this 5 Stars because of its functionality and value! ⭐⭐⭐⭐⭐

The led lights on the front of this unit are ridiculously and unnecessarily bright. It's a crossover -- it doesn't need super bright, always on lights.
