What Is A High-level Input On A Subwoofer?
A high-level input on a subwoofer is a type of connection that allows you to connect your subwoofer directly to your amplifier or receiver’s speaker terminals. This type of connection is typically used in home theaters and car audio systems where a subwoofer is used to enhance the low-frequency response of the system. High-level inputs are usually found on higher-end subwoofers and are designed to provide a more accurate and efficient way of connecting the subwoofer to the rest of the system.
High-level inputs work by tapping into the speaker signal from the amplifier or receiver, allowing the subwoofer to receive the full-range audio signal. This signal is then filtered by the subwoofer’s internal crossover, which separates the low-frequency signals from the rest of the audio signal. The low-frequency signals are then amplified by the subwoofer’s built-in amplifier and sent to the subwoofer driver, producing the low-frequency sound.
What Are The Benefits Of Using A High-level Input On A Subwoofer?
Using a high-level input on a subwoofer provides several benefits, including improved sound quality and increased flexibility. By tapping into the speaker signal from the amplifier or receiver, the subwoofer can receive a more accurate and detailed audio signal, resulting in better sound quality. Additionally, high-level inputs allow for more flexibility in terms of system configuration, as the subwoofer can be connected to any amplifier or receiver with speaker terminals.
Another benefit of using a high-level input is that it eliminates the need for a separate RCA connection, which can be prone to noise and interference. High-level inputs are also typically more reliable and less susceptible to signal degradation, resulting in a more stable and consistent sound. Overall, using a high-level input on a subwoofer can result in a more accurate and enjoyable listening experience.
How Do I Hook Up A High-level Input On A Subwoofer?
Hooking up a high-level input on a subwoofer is a relatively straightforward process. First, locate the high-level input terminals on the subwoofer, which are usually labeled as “high-level” or “speaker level.” Next, identify the speaker terminals on your amplifier or receiver, which are usually labeled as “speaker outputs” or “speaker terminals.” Connect the high-level input terminals on the subwoofer to the speaker terminals on the amplifier or receiver using a set of speaker wires.
Make sure to match the polarity of the speaker wires, with the positive terminal on the subwoofer connected to the positive terminal on the amplifier or receiver, and the negative terminal on the subwoofer connected to the negative terminal on the amplifier or receiver. Once the connections are made, turn on the system and adjust the subwoofer’s settings as needed to achieve the desired sound.
What Type Of Speaker Wire Should I Use For A High-level Input Connection?
For a high-level input connection, it’s recommended to use a high-quality speaker wire that is designed for high-current applications.
