Certifications and Approvals
All Bosch loudspeakers are designed to withstand operating at their rated power for 100 hours in accordance with IEC 268 5 Power Handling Capacity (PHC) standards. Bosch has also developed the Simulated Acoustical Feedback Exposure (SAFE) test to demonstrate that the speakers can withstand two times their rated power for short durations. This ensures extra reliability under extreme conditions, leading to greater customer satisfaction, longer operating life, and much less chance of failure or performance deterioration.

Installation/Configuration Notes
The cabinets include a built in transformer that offers a selection of nominal full power, half power, quarter power or eight power radiation (i.e. in 3 dB steps) for 70 V,
100 V or 8 Ohm bypass.
Selection is done by a convenient switch on the rear enclosure.
A two meter long twin core loudspeaker cable (in matching color with the cabinet) is connected to the loudspeaker. The core ends are stripped ready for use.
The cabinets can be mounted horizontally to allow the loudspeaker to be directed up or down, or vertically to allow left and right rotation by means of a steel U-shaped wall bracket (standard supplied).
The rotatable logo can be easily adjusted to match the mounting orientation.
