Bosch LC4-UC24E Ceiling Wide Angle Loudspeaker, 24 W Power, 101/87dB SPL, 65Hz-20kHz Frequency, 8/208/417Ohms Rated Impedance, Single, Black/White

The Bosch LC4-UC24E Ceiling Wide Angle Black/White Loudspeaker can be used for a wide variety of ceiling environments. They provide excellent speech and music in indoor public address applications. New CosCone driver technology, used in this range, stands for delivering outstanding sound quality from a small sized unit. It ensures a wide and equal spread of all octave frequencies and eliminates high-frequency beaming. Fewer loudspeakers are needed to cover a given area and the noticeable "fading" that can occur as a listener walks from one loudspeaker to another area is eliminated.

It is a light and compact unit with an unobtrusive, neutral designed front grille.

Installation/configuration
The LC4-UC24E is very installation friendly. A cutting template is supplied with each unit and the loudspeaker is secured in ceilings up to 50 mm (2 in) thick using two integral screw driven clamps.

Connections are made using a screw terminal block on the frame, where each incoming and outgoing conductor of the same potential can be connected to a separate screw on a terminal block. Power tapping on both 70 V and 100 V allows selection of full-power, half-power, quarter-power, eight-power radiation and 8 Ohm. A selector at the front of the frame simplifies the required selection of the power setting. The loudspeaker grille, standard supplied, can be secured to the loudspeaker unit with a quick bayonet fitting after installation of the loudspeaker into the ceiling.

Ease of installation for individual loudspeaker and loudspeaker / fire-dome combinations. The metal fire-dome (LC4-MFD) mounting is fixed in the ceiling prior to the ceiling speaker mounting.
