Lb1 ￣ sw60 is an ideal solution to add low frequency

 enhancement in general public broadcasting applications. It is a 60 W subwoofer that reproduces the low frequency part of the full frequency input signal content. The built-in low-pass filter eliminates the need for an external divider. It is equipped with a tuned, reversed phase baffle box and 8 "bass unit to produce a pleasant, warm low frequency response. The subwoofer is designed to work with smaller speakers called satellite speakers. These smaller loudspeakers reproduce the full frequency range, but due to their small size, the low frequency response is insufficient. You can connect one or more subwoofers to Bosch ceiling speakers, speakers, pillars and directional speakers. Built in matching transformers allow you to easily integrate into existing and new constant voltage systems. Certificate and accreditation all Bosch loudspeakers meet IEC 268-5 power handling capacity (PHC) standard and can operate continuously for 100 hours at rated power. In addition, Bosch has conducted simulated acoustic feedback exposure (SAFE) tests to ensure that they can withstand twice the rated power in a short period of time. This ensures high reliability of loudspeakers in 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. For invisible wall mounting, it also comes with wall brackets as standard. The back of the speaker has a screw insert to mount the wall bracket horizontally or vertically on the wall. The drilling template is a standard accessory. Bosch logo can be easily adjusted to match the installation direction. The connection can be established through a 4-way push type terminal block on the back of the speaker (the interface with the same potential at the input and output terminals is separated into a terminal block). A ceramic junction box with temperature fuse is reserved beside the terminal for installation. 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 ohm. The tap selector at the front of the speaker simplifies the power setting. After removing the Bosch logo, you can set this selector. If necessary, the front metal mask can be removed from the speaker to facilitate painting.
