Choosing the Right Crossover and Amplifiers
Before you start connecting your crossover to two amplifiers, you need to choose the right equipment for the job. Here are some factors to consider:
- Crossover Type: There are two main types of crossovers: active and passive. Active crossovers use electronic components to divide the audio signal, while passive crossovers use passive components such as capacitors and inductors. Active crossovers are generally more flexible and accurate, but they require a power source.
- Crossover Frequency: The crossover frequency refers to the frequency at which the audio signal is divided. This will depend on the type of speakers you are using and the frequency range you want to allocate to each amplifier.
- Amplifier Power: The power rating of your amplifiers will depend on the type of speakers you are using and the sound pressure levels you want to achieve. Make sure to choose amplifiers that are powerful enough to drive your speakers.
Connecting the Crossover to Two Amplifiers
Now that you have chosen the right equipment, it’s time to connect the crossover to two amplifiers. Here’s a step-by-step guide:
- Connect the input of the crossover to the output of your preamplifier or mixer. This will provide the audio signal that the crossover will divide.
- Connect the outputs of the crossover to the inputs of the two amplifiers. Make sure to match the frequency range of each output to the corresponding amplifier.
- Connect the outputs of the amplifiers to the inputs of the speakers. Make sure to match the impedance of the speakers to the amplifiers.

What is a crossover and why do I need it for my sound system?
A crossover is an electronic component that divides an audio signal into different frequency ranges, allowing you to send specific frequencies to specific speakers or amplifiers. This is necessary because different speakers are designed to handle different frequency ranges, and sending the wrong frequencies to a speaker can damage it or result in poor sound quality.
By using a crossover, you can ensure that each speaker in your system is receiving the frequencies it is designed to handle, resulting in improved sound quality and increased overall system performance. In the context of connecting a crossover to 2 amplifiers, the crossover allows you to divide the audio signal between the two amplifiers, sending the low-frequency signal to one amplifier and the high-frequency signal to the other.
What are the benefits of using a crossover with 2 amplifiers?
Using a crossover with 2 amplifiers allows you to optimize the performance of each amplifier by sending it only the frequency range it is designed to handle. This can result in improved sound quality, increased power efficiency, and reduced distortion. Additionally, using a crossover can help to prevent damage to your speakers and amplifiers by ensuring that they are not receiving frequencies that are outside of their operating range.
By dividing the audio signal between two amplifiers, you can also increase the overall power output of your system, allowing you to drive larger or more demanding speakers. This can be particularly useful in applications where high sound pressure levels are required, such as in live sound or DJ systems.
What type of crossover do I need for my sound system?
The type of crossover you need will depend on the specific requirements of your sound system. There are two main types of crossovers: active and passive. Active crossovers use electronic components to divide the audio signal, while passive crossovers use inductive and capacitive components.
If you are connecting a crossover to 2 amplifiers, you will typically need an active crossover. This is because active crossovers can provide the necessary gain and signal processing to drive two separate amplifiers. Passive crossovers, on the other hand, are typically used in speaker cabinets or other applications where the crossover is not required to drive an amplifier.
How do I connect a crossover to 2 amplifiers?
To connect a crossover to 2 amplifiers, you will typically need to follow these steps: first, connect the input of the crossover to the output of your mixer or preamplifier. Next, connect the low-frequency output of the crossover to the input of one amplifier, and the high-frequency output to the input of the other amplifier. Finally, connect the outputs of each amplifier to the corresponding speakers.
It’s also important to ensure that the crossover is properly configured for your specific system. This may involve adjusting the crossover frequency, slope, and other settings to optimize the performance of your system. Consult the user manual for your crossover and amplifiers for specific instructions on how to connect and configure your system.
What are the common crossover frequencies and slopes?
The common crossover frequencies and slopes will depend on the specific application and the type of speakers being used. In general, the crossover frequency is the point at which the audio signal is divided between the low-frequency and high-frequency speakers. Common crossover frequencies include 80 Hz, 100 Hz, 120 Hz, and 150 Hz.
The slope of the crossover refers to the rate at which the audio signal is attenuated above or below the crossover frequency. Common slopes include 12 dB/octave, 18 dB/octave, and 24 dB/octave. A steeper slope will result in a more abrupt transition between the low-frequency and high-frequency speakers, while a shallower slope will result in a more gradual transition.
Can I use a crossover with any type of amplifier?
Not all amplifiers are compatible with crossovers. In general, you will need to use an amplifier that is designed to work with a crossover. This typically means using an amplifier that has a high input impedance and a low output impedance.
Some amplifiers, such as those with built-in crossovers or those that are designed for specific applications, may not be compatible with external crossovers. Consult the user manual for your amplifier to determine if it is compatible with a crossover. Additionally, some crossovers may require specific amplifier configurations or settings, so be sure to consult the user manual for your crossover as well.
How do I troubleshoot common issues with my crossover and amplifier setup?
If you are experiencing issues with your crossover and amplifier setup, there are several things you can try to troubleshoot the problem. First, check the connections between the crossover, amplifiers, and speakers to ensure that they are secure and not loose. Next, check the settings on the crossover and amplifiers to ensure that they are properly configured.
If you are experiencing distortion or noise, try adjusting the gain settings on the crossover and amplifiers. If you are experiencing a lack of low-frequency response, try adjusting the crossover frequency or slope. Consult the user manual for your crossover and amplifiers for specific troubleshooting instructions and guidelines.
