Replacement remote for LG soundbars

This replacement remote control operates at 433 MHz using RF wireless communication and is designed for LG soundbar models including AKB73575421 NB2420A NB3520A NB3530A NB3532A NB4530B. The handset measures approximately 16 cm in length and is made from black ABS material for durability. It provides a direct substitute when the original remote is lost or damaged. Power is supplied by two AAA batteries which are not included.

Fits into a home audio setup

The remote requires no pairing process and works immediately with compatible LG soundbars using the 433 MHz RF channel. It frees the user from relying on a smartphone app or the limited controls on the soundbar itself. A clear line of sight up to 10 meters or 33 feet is needed for reliable operation depending on the specific speaker model. No additional cables or receivers are required for installation.

Bundled items and their impact

The package includes only the remote control unit without batteries or retail packaging. Users must supply two AAA batteries to power the 3V handset before first use. The absence of a bundled package reduces waste and keeps the replacement cost low. CE certification confirms the device meets basic European safety and electromagnetic compatibility requirements.
