AN-1001X+ companion speaker monitor is an extremely versatile unpowered speaker. This system is easy to use, lightweight, and provides a powerful 107dB of sound to fill the room with your voice. It is designed to project clear, intelligible speech for a larger audience, and is also great for music. It is not battery powered, and it must be connected to a powered speaker to run. The back panel has a line-in to be powered by an AN-1000X+, or other Anchor sound system. When another AN-1000X+ is paired with this companion speaker, they can reach crowds of 500+ people. The AN-1001X+ can be mounted on a stand, to the wall/ceiling, or placed on a shelf. Just plug it into the powered speaker, and you are ready to go. It's ideal for presentations and can be added to an A/V rack setup. Use it as a studio monitor, install it in a trade show booth, or even place is in the Captain's quarters on a US Navy warship to monitor activities in the intelligence room.
