To connect an active PA speaker to a passive PA speaker, you will need to use a powered mixer or an external power amplifier. First, connect the main output of the active PA speaker to the input of the powered mixer or power amplifier. Then, connect the passive PA speaker to the output of the powered mixer or power amplifier. Make sure to use the appropriate cables and set the levels and settings on the mixer or amplifier to ensure proper signal flow and balance between the active and passive speakers. **

You can buy an active PA system by first determining your specific needs and budget. Research different brands and models to find one that suits your requirements. You can then purchase the system from a music equipment store, online retailer, or directly from the manufacturer. Make sure to consider factors such as power output, speaker size, and additional features like built-in mixers or Bluetooth connectivity. Finally, ensure that the system comes with a warranty and consider purchasing any necessary accessories such as stands or cables. **

Yes, there are PA systems that do not have an active crossover. Passive crossovers can be used in PA systems to split the audio signal into different frequency ranges before sending them to the appropriate speakers. While active crossovers offer more control and flexibility, passive crossovers can still be used effectively in PA systems to achieve the desired sound distribution. However, active crossovers are becoming more popular due to their ability to provide better sound quality and system efficiency. **

In an active PA system, a crossover works by splitting the audio signal into different frequency bands, such as low, mid, and high frequencies. Each frequency band is then sent to the corresponding speaker or driver, such as a subwoofer for low frequencies, a woofer for mid frequencies, and a tweeter for high frequencies. This allows each speaker to focus on reproducing a specific range of frequencies, resulting in a more balanced and accurate sound reproduction. The crossover is typically built into the amplifier or speaker system and can be adjusted to tailor the sound to the specific needs of the venue or performance. **

Passive PA speakers require an external power amplifier to drive the audio signal and produce sound, while active PA speakers have a built-in power amplifier. This means that passive speakers need to be connected to an external amplifier, adding to the overall setup and potentially requiring more space and cables. Active speakers, on the other hand, are more self-contained and easier to set up, as they only need to be connected to a sound source. Additionally, active speakers often have built-in features such as EQ controls and signal processing, making them more versatile and easier to use for live sound reinforcement. **

The subwoofers may not work when the active PA tops are active because the crossover settings may not be properly configured. The crossover settings determine which frequencies are sent to the subwoofers and which are sent to the tops. If the crossover settings are not set correctly, the subwoofers may not receive the low frequencies they are designed to reproduce. Additionally, there may be a problem with the signal routing or connections between the tops and the subwoofers, causing the subwoofers to not receive the necessary signal to produce sound. Troubleshooting the crossover settings and signal routing can help resolve the issue and ensure that both the tops and subwoofers work together effectively. **

The QSC KS112 active PA subwoofer is a good complement to the Soundboks Gen3. It features a powerful 2000-watt Class D amplifier and a 12-inch direct radiating driver, providing deep and punchy bass that complements the Soundboks Gen3's high-quality sound. Additionally, the compact and portable design of the QSC KS112 makes it easy to transport and set up alongside the Soundboks Gen3 for a complete and powerful sound system. **
