Section 7: Connection Types

There are two basic types of audio system interconnections for audio signals: Balanced and Unbalanced. Your EON® can accept either type of input.

Balanced Lines

In audio, a balanced line is a three-conductor system in which the two signal wires carry an equal, but opposite voltage with respect to the ground wire. The ground wire acts only as a shield and does not carry any audio signal current. Outside interference (such as RFI - Radio Frequency Interference) is either shielded from the internal signal conductor, or if it gets into the cable is cancelled out by the opposite signals at the receiving end. Balanced connections are preferred for any longer cable runs.

Unbalanced Lines

Unbalanced cable is a two-wire system where the shield (ground wire) acts as one of the current carrying signal conductors. The center conductor enclosed by the shield is commonly known as the “hot” conductor. Unbalanced audio cables do not reject noise as well as balanced lines.

Unbalanced lines are typical in home hi-fi type systems and on the outputs of electronic musical instruments. These work well if the distance between the components is short, the signal level is relatively high and all of the electronics used in the system are plugged into the same AC service.

Unbalanced Sources to EON Powered Loudspeakers

If you need to connect your EON speakers to an unbalanced source you have two options:

•Use the LINE 1 and LINE 2 connectors. These inputs are balanced but will accept unbalanced inputs without the need for any special adapters.

•Use an adapter or special cable

518S specifications

The Harman 518S is an impressive subwoofer that embodies powerful performance and sophisticated technology, making it a popular choice for both audiophiles and casual listeners. Renowned for its deep, impactful bass, the 518S enhances audio experiences across various applications, including home theaters, music systems, and professional setups.

One of the standout features of the Harman 518S is its robust 18-inch driver, which is designed to deliver low frequencies with remarkable clarity and precision. This large driver is complemented by a high-quality enclosure that minimizes unwanted vibrations, ensuring that audio reproduction remains clean and undistorted. The subwoofer is engineered to provide a frequency response that reaches as low as 20 Hz, allowing users to experience the full spectrum of sound in movies and music.

Incorporating cutting-edge technologies, the Harman 518S utilizes advanced digital signal processing (DSP) to optimize performance. The DSP capabilities enable intelligent management of bass output, adapting the sound to the acoustics of the surrounding environment. This ensures that the subwoofer can deliver optimal sound quality regardless of placement, providing flexibility in setup without sacrificing performance.

The build quality of the Harman 518S is another highlight. Constructed with durable materials, it is designed to withstand the rigors of both professional and residential use. The cabinet's design also aids in reducing resonance, further enhancing sound fidelity. The subwoofer features versatile connectivity options, making it compatible with various audio systems. Users can easily connect the 518S to receivers, processors, or amplifiers, simplifying integration into existing audio setups.

Another key characteristic of the Harman 518S is its adjustable volume and crossover settings. This allows users to tailor the audio output according to their preferences and the specific demands of their listening environment. Whether it’s for a cinematic experience or a music listening session, the subwoofer can be fine-tuned to achieve the perfect balance.

In summary, the Harman 518S is a powerful subwoofer that combines a large 18-inch driver, advanced DSP technology, and robust construction. Its ability to deliver deep, high-quality bass makes it a sought-after component in any serious audio setup, ensuring an immersive listening experience that resonates with every beat. Whether you are a movie buff or a music lover, the Harman 518S promises to elevate your audio experience to new heights.
