It’s important to understand that a crossover isn’t a filter, nor is it a bandpass filter. A crossover is actually a combination of two filters, or more specifically, two bandpass filters.
How to connect crossover to an amplifierHow to connect crossover to an amplifier? A crossover is used to cut off frequencies that the amplifier can’t handle. It’s like the difference between having a speaker with an 8-inch woofer and a 12-inch woofer. If the amplifier only has a 10-inch woofer, you can still use an 8-inch crossover and it will still cut off the frequencies that are too high for the amplifier.
The same thing goes for a guitar amp. It doesn’t matter how big the speakers are, if the amplifier only has a 5-watt amp, it can’t handle anything over about 10k Hz. That’s why we need a crossover. The crossover divides the frequencies into two bands. One band is the frequencies that the amplifier can handle, and the other is frequencies that the amplifier can’t handle.
Steps To Connect a Crossover To An Amplifier:
A crossover is an electronic device used to separate or reject frequencies that are above or below a specific frequency. Crossovers are used to increase the range of audio equipment, as well as reduce distortion.
Crossover (high frequencies) and Amplifier (low frequencies) are two distinct types of speakers, but what if you wanted to use them together? This would create an amazing sound. But, where would you get the crossover network?
Here are the steps, including the circuit and instructions on how to build it.
STEP 1. Selecting The Right Crossover For The Project:
In selecting a crossover, the most important factor to consider is the frequency range that you want to use it for. This ranges from low frequencies to high frequencies. To determine what frequencies fall into each category, select a radio station with a strong signal that spans all the frequency bands that you need to cover.
STEP 2. Using The Crossover To Separate Frequencies:
Next, adjust the crossover so that the frequency range of interest is within its scope. The frequency range for the project may be from 20 Hz to 20 kHz. This will leave some frequencies outside of the range and these should be rejected. The selected range for the project is between 200 Hz and 20 kHz.
STEP 3. Find a Speaker Cabinet:
The first step is to find a speaker cabinet. It should ideally be a powered speaker cabinet, so you can drive the speaker with a power amplifier. You will need to purchase a speaker cabinet with a powered subwoofer.
This will help you to control the bass from the amplifier. You also want to make sure that the speaker cabinet has a separate volume knob for the crossover. You want to be able to easily adjust the high frequencies.
STEP 4. Build the Crossover Network:
There are three things you need to build for the crossover network:
-
A line level audio mixer. This will allow you to mix between the different speaker outputs.
-
A separate volume control for the crossover. This is important to adjust the frequency range of the speaker cabinet.
-
A power splitter to separate the low frequency speakers from the high frequency speakers. This will allow you to keep the low frequencies and the high frequencies separate.
STEP 5. Connecting the Speaker Wire to the Crossover:
Start by identifying where the speaker wire attaches to the crossover. Usually there’s a black, red, and white wire in the bundle. You’ll want to attach the black and red wires together (this is the positive side of the speaker wire).
The positive side is the wire with the stripe on it. It connects from the speaker wire to the crossover.
STEP 6. Attach the Black and Red Wires Together:
Attach the black and red wires together with a soldering iron or solder.
STEP 7. Attach the Black and Red Wires to the Crossover:
Connect the black and red wires to the crossover. There should be a slot in the crossover for the wire to go through.
STEP 8. Attach the Crossover to the Amplifier:
Attach the crossover to the amplifier. Usually there’s a hole in the back of the amplifier, or the amplifier will have a bracket. Insert the crossover into the hole and then push down firmly until it clicks into place.
STEP 9. Connect the Positive and Negative Wires:
Connect the positive and negative wires to the amplifier.
STEP 10. Check Your Connections:
Check the connections and make sure that all the wires are connected. If there are any loose wires, reconnect them now.
STEP 11. Test Your Connection:
Test your connection. If the speaker wire does not turn on the amplifier, the wiring needs to be checked.
Steps 1-7 are the general steps to connecting the speaker wire to the crossover and amplifier. In your case, you may need to adjust the steps to fit your specific application.
STEP 12. Connecting The Crossover To The Amplifier:
Next, connect the crossover to the amplifier. You may also need to plug the input into a jack or output to a jack. Once connected, the crossover should have no effect on the signal unless there is a power source connected to the amplifier.
Once you have everything built, you need to connect the power amplifier to the speaker cabinet. You will also need to connect the line level audio mixer to the speaker cabinet.
STEP 13. Play the Speakers:
Once you have everything connected, it’s time to play the speakers. It’s important to note that you should only play the speakers for a short period of time.
Once you do, you will need to turn off the speakers. This will prevent any damage from the speakers. After playing for a short time, you will have the opportunity to adjust the volume and the frequency range.
