This ceiling speaker gives sound distribution for a wide scope of ceiling mounted applications. These are ideal for hotels, restaurants, shopping centers, convention centers, office buildings, etc. where both speaker and music reproduction of high quality is required. BOSCH LC1-PC15G6-6-IN 15 W Ceiling Speaker is a circular shaped, ABS material ceiling loudspeaker and has full-range performance in the bandwidth of 100 Hz to 20 kHz. The speaker has a line matching transformer to connect to a 100V output from an amplifier. The loudspeaker has power tappings at full power (15W), half power (7.5W), and quarter power (3.75W) to connect at different power levels. The LC1-PC15G6-6-IN model ceiling speaker is for direct connection to a 100 V line output and is finished in white (RAL 9003) color. The ceiling loudspeaker comes with a 100 V transformer with taps on the primary winding to allow different power tappings. Nominal full-power, half-power or quarter-power radiation (in 3 dB steps) can easily be selected by connecting the amplifier output to the appropriate tapping. All Bosch loudspeakers are designed to withstand operating at their rated power for 100 hours in accordance with IEC 60268-1 and IEC 60268-5 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. 100 hours PHC (Powering Handling Capaclty) test in acc. to IEC 60268-1&5 Technical Specifications: Manufacturer     Bosch   Brand     Bosch   Model No     LC1-PC15G6-6-IN   Generic Name     Ceiling Speaker   Maximum Power     22.5 W   Rated Power     15 W   Mount Position     Ceiling   Load Capacity     900 g   Rotatable Power taps at 100 V     15 W – 7.5 W – 3.75 W   Sound Pressure Level at 6 W / 1 W ( 1 KHz at 1m)     88 dB (±3 dB)   Effective Frequency Range (-10 dB)     100 Hz to 20 kHz   Opening Angle at 1 KHz / 4 KHz (-6 dB)     1 K : > 180? 2 K : 180? 4 K : 77? 8 K : 40?   Rated Input Voltage     100 V   Rated impedance at Rated Power     666 / 1333 / 2666 Ohm   Driver/Speaker Diameter     5 in / 8 in   Safety     Refer to EN 60065   Material     Metal   Color     White   Weight     1.2 Kg
