The JBL Control 1X is a personal-size monitor loudspeaker designed to deliver high-quality audio reproduction in various home and office environments. This product is a testament to JBL's extensive experience in audio, spanning over 50 years in music and film recording and reproduction. The Control 1X is engineered to provide an enjoyable listening experience, whether for music, movies, or other audio content.

Function Description

The primary function of the JBL Control 1X loudspeaker is to convert electrical audio signals into audible sound. It is designed to be a versatile audio output device, suitable for use as front or rear speakers in a stereo or home theater setup. The loudspeaker is capable of reproducing a wide range of frequencies, ensuring that both high-frequency details and lower-frequency sounds are rendered accurately. Its design emphasizes clarity and impact, making it suitable for various audio applications.

Usage Features

The Control 1X boasts several features that enhance its usability and performance:

Rugged, High-Impact Molded-Plastic Cabinet: The speaker enclosure is constructed from durable, high-impact molded plastic. This robust construction ensures longevity and resilience, protecting the internal components from physical damage. The ruggedness makes the Control 1X suitable for various environments, including those where a more durable speaker might be beneficial.
Video-Shielded: A significant feature for modern entertainment setups, the Control 1X is video-shielded. This means that the speaker's magnetic field is contained, preventing interference with nearby video displays, such as televisions or computer monitors. This allows for flexible placement options, including close proximity to screens, without causing image distortion or discoloration.
Optional Adjustable Wall-Mount Brackets: For enhanced placement flexibility, optional adjustable wall-mount brackets are available. These brackets allow the Control 1X loudspeakers to be securely mounted on walls, optimizing sound dispersion and saving floor or shelf space. This feature is particularly useful for creating a clean, integrated look in a home theater or multi-room audio system. The product is specifically designed for wall-mounting and is not intended for ceiling mounting.
Speaker Placement Versatility: The Control 1X can be effectively used in various configurations:
- As Front Speakers: When used as front speakers, they should be positioned to create a stereo image, typically flanking a television or projection screen. Proper placement ensures a balanced soundstage and accurate localization of audio elements.
- As Rear Speakers: In a surround sound setup, the Control 1X can serve as rear speakers, contributing to an immersive audio experience. When placed behind the listening position, they help create a sense of depth and envelopment, crucial for movie soundtracks and multi-channel music. The manual suggests a typical spacing of 5-6 feet between rear speakers for optimal effect.
Easy Connection: Connecting the Control 1X to an amplifier or receiver is straightforward. The speakers and electronics terminals are clearly marked with corresponding (+) and (-) symbols. It is crucial to connect both speakers identically, ensuring that the (+) terminal on the speaker connects to the (+) terminal on the amplifier, and the (-) terminal on the speaker connects to the (-) terminal on the amplifier. This "in-phase" connection is vital for proper sound reproduction. Incorrect wiring, or "out of phase" connection, can lead to thin sound, weak bass, and a poor stereo image, significantly diminishing the listening experience. The manual provides a clear diagram illustrating the correct wiring for both left and right channels from front or rear speaker outputs.

Maintenance Features

While the JBL Control 1X is designed for durability and reliable performance, some basic maintenance considerations are outlined to ensure optimal operation:

Connection Integrity: Regular checks of all wiring and connections are recommended. Users should ensure that speaker wires are securely connected to both the speakers and the amplifier/receiver. It is also important to inspect the wires for any signs of fraying, cuts, or punctures, as damaged wires can lead to intermittent sound or complete signal loss. Maintaining intact and secure connections is fundamental for consistent audio output.
Troubleshooting Guidance: The manual provides a helpful troubleshooting section to address common issues:
- No Sound from Any Speakers: If no sound is heard, the first step is to verify that the receiver/amplifier is powered on and that an audio source is actively playing. Reviewing the proper operation of the receiver/amplifier is also advised.
- No Sound from One Speaker: If only one speaker is silent, users should check the "Balance" control on their receiver/amplifier, as it might be shifted to one side. Additionally, all wires and connections between the receiver/amplifier and the problematic speaker should be inspected for any disconnections or damage.
- System Shuts Off at High Volumes: If the system plays at low volumes but shuts off when the volume is increased, it often indicates an issue with connections. Users should check all wires and connections between the receiver/amplifier and speakers, ensuring they are secure and free from damage. This can prevent potential short circuits or overloads that might trigger protection circuits in the amplifier.
- No or Low Bass Output: A lack of bass can often be attributed to incorrect wiring polarity. Users should ensure that the polarities (+ and -) of the left and right "Speaker Inputs" are connected properly, meaning all speakers are wired in phase.
- Multiple Speaker Pairs: If more than one pair of main speakers is being used with the same amplifier, it is crucial to check the minimum impedance requirements of the receiver/amplifier. Exceeding the amplifier's capacity by connecting too many low-impedance speakers can lead to overheating or damage.

By adhering to these usage and maintenance guidelines, users can ensure that their JBL Control 1X loudspeakers provide many years of high-quality audio enjoyment. The robust design and clear instructions contribute to a user-friendly experience, reflecting JBL's commitment to delivering reliable and high-performing audio products.
