Lend Me Your Ears

Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in susceptibility to noise-

induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a period of time. The U.S.

Government’s Occupational Safety and Health Administration (OSHA) has specified the permissible noise level exposures shown in this chart.

According to OSHA, any exposure in excess of these permissible limits could result in some hearing loss. To ensure against potentially dangerous exposure to high sound-pressure levels, it is recommended that all persons exposed to equipment capable of producing these levels use hearing protectors while this unit is in operation. Ear plugs or protectors in the ear canals or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss if exposure is in excess of the limits set forth here.

INTRODUCTION

Thank you for choosing Mackie Designs’ active sound reinforcement speaker systems.

The SRS1500 is a high output active subwoofer system. It features a high-precision 15˝ transducer combined with application specific amplifier technology. The system is composed of a single, compact subwoofer cabinet with built-in control and amplifier electronics.

Connecting and setting up the SRS1500 is a breeze. It accepts a stereo line-level signal via female XLR input jacks. Male XLR Thru jacks are provided for daisy-chaining the signal to additional SRS1500 cabinets. The built-in crossover separates the low frequencies from the high frequencies, and routes the high frequencies to the male XLR high-pass output jacks. Connect these to the inputs of full-range active speakers such as the Mackie Designs SRM450s, or to an amplifier powering a pair of passive speakers such as the Mackie Designs

M•1400i and C300s. A Phase switch gives you the option of reversing the polarity of the signal to the full-range speakers by 180º. A Subwoofer Level control allows you to adjust the balance between the subwoofer and the full-range speakers.

The built-in amplifier produces 600 watts of continuous power. The amplifier module sits on a mammoth heatsink that eliminates the need for fans, dramatically extending life expectancy, and eliminating maintenance cycles. A tremendous benefit of having the amplifier located within the subwoofer cabinet is that the SRS1500 functions as a system, optimizing acoustic, electronic, and mechanical designs to achieve the highest level of performance and value.

The cabinet is constructed with 18mm thick multi-layered birch plywood. Carrying handles are integrated into each side for easy loading and transport.
