Mackie SA1530Z 3-Way Active Loudspeaker System

A pair of Mackie SA1530Z 3-Way Active Loudspeaker System speakers. These are beasts are no longer produced. The system is in excellent working condition, with some wear to the exterior, as pictured. Wooden rails were added to the back to protect the back panel from damage during transportation (again, as pictured).

From the owner's manual:

• The SA1530z is a high-efficiency, extreme output, horn-loaded, 3-way, wide-dispersion, active sound reinforcement system. It features a one-piece 90º x 40º horn, which includes both the mid- and high-frequency sections in a proprietary optimized Wavefront™ design. Unlike typical mid/high horn designs, the high-frequency section is positioned to fire down into the 6-inch midrange’s dispersion pattern. This creates a focused, single wave front with excellent phase and power response characteristics. The resulting 90º x 40º dispersion pattern provides a very open, natural sound at extreme output levels.
• Three built-in power amplifiers provide 100 watts rms each for the mid-frequency and high-frequency drivers, and 1100 watts rms for the low-frequency driver. The amplifier modules sit on a mammoth aluminum heatsink that eliminates the need for fans. A tremendous benefit of having the amplifiers located within the loudspeaker cabinet is that the SA1530z functions as a system, optimizing acoustic, electronic, and mechanical designs to achieve the highest level of performance and value.
• The 6-inch neodymium mid-range transducer operates between 700 Hz and 3000 Hz, eliminating the placement of a crossover point in the middle of critical voice frequencies. Frequencies above 3000 Hz are reproduced by a 1.75-inch neodymium compression driver. The low frequencies are produced by a high-output 15-inch woofer with a 4-inch high-temperature voice coil.
• Connecting and setting up the SA1530z is a breeze. It accepts a line-level signal via a female XLR input jack. A male XLR Thru jack is provided for daisy-chaining the signal to additional SA1530z cabinets.
• The rear mounted amplifier assembly features separate signal and AC power panels separated by the heatsink. The signal input panel contains:

- an input XLR and loop-through XLR

- a volume level control

- Power ON indicator

- Signal Present indicator

- Limit indicator

- Thermal Protection indicator

• The cabinet is constructed using both 18 mm multilayered plywood and pressure injected structural resin. A carrying handle is integrated into each side for easy loading and transport,
