Introduction The AMT-12 is designed to deliver high-output music and sound reinforcement in a lightweight package. The 12-inch woofer has high sensitivity to maximize amplifier output. The 1.77-inch compression driver diaphragm, comprised of an aluminum alloy for added strength and rigidity, effortlessly handles the high input levels to match the woofer. A carefully designed cross-over network accurately filters each driver for proper matching of phase and summation in the cross-over region.
Powering the Loudspeaker Amplifier Selection It is important that the appropriate amplifier be used for a specific loudspeaker to avoid accidental driver damage. Underpowered amplifiers will clip easily, sending a highly distorted signal to the speaker. This distorted signal has a far greater density of energy than normal program and will “burn out” drivers quickly. Note: Be certain that the total impedance of all interconnected speakers is not lower than the amplifier’s minimum rated impedance.
Daisy-Chaining Speakers In this example, pins 1+ and 1- on the Input (Left) connector receive full-range audio from the amplifier or from a previous speaker in a chain. The Loop-Thru (Right) connector uses the 1+ and 1- pins to send full-range audio to the Input connector of another speaker in a chain. Loop-Thru connects all speakers in the chain in parallel. Make sure the total impedance of the chain is not less than what the amplifier is rated to handle.
