This document is a simple manual for the LG Wireless Rear Speakers Kit, model SPJ4-S, designed to enhance the audio experience by adding surround sound capabilities to a compatible LG sound system. The kit includes wireless rear speakers and a wireless receiver, facilitating a clutter-free setup and immersive audio.
The LG Wireless Rear Speakers Kit serves to augment a main sound unit by providing dedicated rear channel audio, thereby creating a surround sound environment. When integrated with a compatible LG soundbar or audio system, these speakers reproduce the rear audio channels, enveloping the listener in a more dynamic and realistic soundstage. This is particularly beneficial for movies, games, and music, where spatial audio cues are crucial for immersion. The wireless nature of the kit eliminates the need for long speaker cables running across the room, simplifying installation and maintaining a cleaner aesthetic. The system is designed for automatic connection, making the setup process straightforward for most users.
The primary usage feature of this kit is its ability to deliver surround sound. Once connected, users can activate a "Surround" function on their main unit to enjoy the enhanced audio. The manual outlines specific steps for different LG soundbar models (SJ4R/SJ4Y and SJ5Y) to enable or disable this function. For SJ4R/SJ4Y models, activating surround sound involves pressing and holding the "REAR LEVEL +" button on the remote control for approximately two seconds. To deactivate, the "REAR LEVEL -" button is pressed and held for the same duration. For SJ5Y models, the process involves pressing and holding the "AUTO VOL" button on the remote control for about two seconds, then repeatedly pressing "AUTO VOL" to cycle through and select "ON - SURROUND" or "OFF - SURROUND" in the display window. This flexibility ensures compatibility and ease of control across different LG audio systems.
The connection process for the wireless rear speakers is designed to be user-friendly. First, the speaker cables are connected to the rear speakers themselves, ensuring correct polarity (transparent for positive, black stripe for negative). Next, these speakers are connected to the wireless receiver using the provided speaker cables, with specific color coding (Grey for right, Blue for left) to guide the user. Finally, the power cord of the wireless receiver is plugged into an electrical outlet. Upon powering on the main unit, the wireless receiver and the main unit are expected to connect automatically, indicated by a solid yellow-green LED on the receiver. This automatic pairing simplifies the initial setup, allowing users to quickly enjoy their new surround sound system.
In cases where automatic connection does not occur, the kit provides a manual pairing option. This involves pressing the "PAIRING" button located on the rear of the wireless receiver. When the pairing mode is active, the yellow-green LED on the receiver will blink quickly. Subsequently, turning on the main unit will complete the pairing process, and the LED on the wireless receiver will turn solid yellow-green, confirming a successful connection. This manual override ensures that users can establish a connection even if the automatic process encounters an issue, providing a reliable solution for sound output.
The wireless design of the kit offers significant convenience, reducing cable clutter and allowing for more flexible placement of the rear speakers within a room. This is particularly advantageous in living spaces where running long speaker wires might be impractical or aesthetically undesirable. The ability to easily enable or disable the surround function also provides users with control over their audio experience, allowing them to switch between standard stereo and immersive surround sound as desired, depending on the content they are consuming.
The manual does not explicitly detail maintenance features in terms of cleaning or repair. However, the design implicitly suggests minimal user maintenance. The robust construction of the speakers and receiver implies durability under normal operating conditions. The "About Ferrite Core (Optional)" section, while not directly a maintenance feature, indicates that some units may include ferrite cores to mitigate electromagnetic interference. If present, these cores are typically installed by wrapping the speaker cables around them, usually twice, near the connection points. This helps in maintaining signal integrity and preventing potential audio disruptions, contributing to the overall performance and longevity of the system by ensuring clean audio transmission. Users are advised to handle the components with care, particularly during connection and placement, to avoid physical damage. The wireless nature also means fewer physical connection points that could wear out over time compared to a fully wired system, potentially reducing the need for frequent checks or adjustments. The simplicity of the system's design, with its focus on automatic and manual pairing, suggests that troubleshooting is primarily limited to ensuring proper power supply and correct cable connections, rather than complex internal adjustments.
