The cabinets have a provision for internally monting the optional line/lodspeaker spervision board. ertifications and approvals All Bosch lodspeakers are designed to withstand operating at their rated power for 1 hors in accordance with IE 268 Power Handling apacity (PH) standards. Bosch has also developed the Simlated Acostical Feedback Exposre (SAFE) test to demonstrate that the speakers can withstand two times their rated power for short drations. This ensres extra reliability nder extreme conditions, leading to greater cstomer satisfaction, longer operating life, and mch less chance of failre or performance deterioration.
