Lend Me Your Ears

Exposure to extremely high noise levels may cause per-

manent hearing loss. Individuals vary considerably in susceptibility to noise-

induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense

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 (such as the M•2600) use hearing protectors while this unit is in operation. Ear plugs or protectors in the ear canals

At Mackie, we know what it takes to be roadworthy. After all, our mixers have traveled all over the world under the worst of conditions, and we’ve applied what we’ve learned to the mechanical design of our amplifiers.

Reliability is paramount to sound reinforce- ment. That’s why we use double-sided thru-hole- plated fiberglass printed circuit boards. That’s why our engineers have subjected the amplifier to the most rigorous and fiendish tests imaginable to fine-tune the design and extend its limits beyond those of ordinary amplifiers.

Our Fast Recovery (FR) amplifiers perform better than conventional designs when presented with adverse conditions such as clipping. Conventional designs use lots of negative feedback to provide stability and lower distortion. When clipping occurs, this “feedback” causes high- frequency sticking, keeping the amplifier “latched” in the clipping state longer than necessary. This results in painfully audible distortion. The Fast Recovery design eliminates this high-frequency sticking and allows the amplifier to remain stable when powering highly reactive loads at high volume levels.

Carefully read and follow all the safety instructions explained on page 2 and throughout the manual. The Quick Start guide on page 4 gives an overview of the amplifier, and the rest of the manual explains the wealth of features and operating instructions in loving detail.
