INTRODUCTION

mammoth aluminum heatsink that eliminates the need

for fans. A tremendous benet of having the ampli-

ers located within the loudspeaker cabinet is that the

SR1521z functions as a system, optimizing acoustic,

electronic, and mechanical designs to achieve the high-

est level of performance and value.

The rear mounted amplier 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 Baltic

birch plywood and pressure injected structural resin.

A carrying handle is integrated into each side for easy

loading and transport.

Thank you for choosing Mackie’s active sound reinforce-

ment loudspeaker systems.

The SR1521z is a high-efciency, high output, horn-

loaded, 2-way, wide-dispersion, active sound reinforce-

ment system. The SR1521z benets from the integration

of 500 watts of amplier power, complete active control

electronics, and precision transducer components.

These elements together form a speaker system with

unprecedented output, resolution, and clarity.

The 1.75-inch neodymium high-frequency compres-

sion driver features a low-distortion optimized symmet-

ric phase plug.

The low frequencies are produced by a high-output

15-inch woofer featuring a 2.5-inch high-temperature

voice coil.

Connecting and setting up the SR1521z 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 SR1521z cabinets.

Two built-in power ampliers provide 100 watts rms

for the high-frequency driver and 300 watts rms for the

low-frequency driver. The amplier modules sit on a
