Q-CS Power1 Powered Loudspeaker



Full frequency sound and particularly broad coverage, with direct connection to video projectors and computers with no additional equipment needed.

The Q-CS Power1 is a compact powered loudspeaker with a built in 15W amplifier. The Q-CS is designed for low finished ceiling installations requiring clear voice announcements and full-range music reproduction, even at background levels.

Ideal for • Classrooms • Meeting Rooms • Conference Centers • Boardrooms • Lecture Rooms • any other low ceiling applications where convenience and simplicity of a powered loudspeaker are desired.

The Power1 amplifier features two inputs that each accept L and R stereo signals, which are electronically summed internally, eliminating the need for external stereo to mono passive summing devices. Both inputs have gain trim, and there is a master gain control. The Q-CS features a coaxial 8 in. driver. Like all Soundsphere loudspeakers, it offers 180° x 360° dispersion. Fewer speakers are needed for better coverage – a single Q-CS Power1 can cover a large area with high quality sound.
