SELF POWERED SUBWOOFERPosted by John on April 11th, 2016 Introduction Apogee Powered Loudspeaker Systems are highly-engineered products that combine advanced-technology amplifiers, sophisticated signal processing, and state-of-the-art drivers housed in rugged, roadworthy loudspeaker enclosures. They are suitable for a wide variety of applications, ranging from portable use for shows and events in all types of venues to permanent installations in auditoriums, churches, theaters, stadiums, meeting rooms, boardrooms, and similar locations. High- self powered subwoofer, capable of providing clean, undistorted low frequency sound at very high output levels. They form powerful arrays when used in multiples with like units. The enclosures are designed for easy truck-packing and handling, and can be safely flown from their built-in rigging points. They are designed to augment. Apogee’s full-range powered speaker family, but they are equally effective when used with conventional, non-powered loudspeakers. The APL-10 and APL-12 feature extended bass down to 34 Hz and 32 Hz, respectively, rapid transient response, and exceptionally low distortion, making them capable of fulfilling a wide range of professional sound reinforcement requirements. Apogee powered products are exhaustively engineered and finely crafted. They will provide years of trouble-free service if care is taken in their use and maintenance. It is recommended that you read this manual and retain it in a convenient location for future reference. Controls (1) Level Control A single level control is located just above the XLR input. Under normal circumstances, the level control should be turned fully clockwise to the 0 position. This is full gain, or 0 dB of attenuation. In certain environments, for example, very quiet productions, it may be desirable to reduce the gain of the powered speaker to improve the overall gain structure of the entire audio system and possibly reduce system noise slightly. This is easily achieved by turning the level down to the desired amount of attenuation. When multiple speakers will be attenuated, it is best to count the detent positions as the level control is adjusted. By doing this, you will be able to accurately set each speaker to exactly the same attenuation. It is important to confirm that the level is set appropriately before deploying the speaker into a location where it will be difficult to reach. (2) Mute Control Each channel of the internal amplifier has a user accessible mute button. Muting the LF1 or LF2 amplifier output can be useful in troubleshooting a system. The two buttons are labeled Ch1 and Ch2. Channel 1 is the LF1 amp and Channel 2 is the LF2 amp. Mute is enabled when the button is out. It is important to confirm that both buttons are depressed (un-muted) before deploying the speaker into a location where it will be difficult to reach in order to un-mute a channel.
