LB1 SW60 is an ideal solution for adding low-frequency enhancement to a common public broadcast application. It is a 60 W low tone speaker, which can reproduce the low frequency part of the full frequency input signal. The built-in low pass filter eliminates the need for an external part frequency converter. It is equipped with a tuned, inverting baffle box and an 8 "bass unit, thus producing a pleasant and enthusiastic low-frequency response. The bass speaker is designed to be used in conjunction with a smaller speaker (called the "satellite speaker"). These smaller speakers can reproduce a complete range of frequencies, but due to their small size, the low-frequency response is insufficient. You can connect one or more of the bass speakers to the Bosch ceiling speakers, speakers, speakers, and strong directional speakers. The built-in matching transformer allows you to easily assemble in both existing and new fixed voltage systems. All Bosch speakers are certified to meet IEC 268-5 power handling capacity (PHC) standards and can operate continuously for 100 hours at rated power. Bosch has also conducted simulated acoustic feedback exposure tests to ensure they can withstand twice the rated power in a short period of time. This ensures high reliability of the speaker under extreme conditions, improves customer satisfaction, extends service life, and significantly reduces the probability of failure or performance degradation. CE compliance statement safety compliance EN 60065 regional certification European CE installation/configuration lb1-sw60 can be placed on the floor or mounted on the wall. In order to install the invisible wall, it is also marked with a wall bracket. The back of the speaker box is provided with screw inserts to install wall bracket horizontally or vertically on the wall. Drilling templates are standard parts. The Bosch logo can be easily adjusted to match the installation direction. A connection can be established through a four-way push connector on the back of the speaker box (the interface with the same potential at the input and output ends is separated into a single connector). A ceramic junction box with a temperature fuse is reserved for installation of the selected terminal. The 70 V and 100 V power taps allow the user to select full power, 1/2 power, 1/4 power, 1/8 power, and 4 ohms. The tap selector at the front of the speaker box simplifies the power setting. This selector can be set after the Bosch logo is removed. If necessary, remove the front metal mask from the speaker box to facilitate painting.
