Lend Me Your Ears

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

in susceptibility to noiseinduced 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.

INTRODUCTION

Thank you for choosing a Mackie Designs power amplifier! The M•2600 is designed to fulfill the amplification needs of almost any type of application, with solid design features such as:

• 2600 watts into 4 ohms, bridged

• 1700 watts into 8 ohms, bridged

• 1300 watts x 2 into 2 ohms, stereo

• 850 watts x 2 into 4 ohms, stereo

• 500 watts x 2 into 8 ohms, stereo

• Easily handles 2 ohm loads all night long

• Two low-cut filters, 2nd-order Bessel, 12dB/octave, variable from Off to 170Hz

• Two superior design active crossovers, 4th-order Linkwitz-Riley, 24dB/octave, selectable crossover point at 60, 90 or 120Hz

• Switchable limiter

• Automatic soft turn-on and multiple protection circuits

• Balanced/unbalanced 1/4" and XLR inputs

• XLR thru outputs, selectable to full-range, high pass or low pass

• Speakon® or binding post outputs

• Superior T-Design fan cooling

• Ultra low noise and distortion

• Fast Recovery design

• Five year warranty

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 reinforcement. That’s why we use double-sided thru-holeplated 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.

Part No. 0003364 Rev. A 05/02

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

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.

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 highfrequency 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.

Please write your serial number here for future reference (i.e., insurance claims, tech support, return authorization, etc.):

INSTALLATION

The M•2600 amplifier must only be installed in a rack. See page 29 for special details regarding rack mounting and thermal

considerations. DO NOT BLOCK THE VENTILATION PORTS The M•2600 draws its ventilation air in from the front and out through the side panels. It needs plenty of fresh air to stay cool.

AMP MODE

is best

for your application:

STEREO

•

mode (separate left and right inputs, separate left and right outputs) is the typical setup for amplifying stereo signals.

MONO

•

mode (sometimes called DualMono mode — one or two inputs, two mono outputs) is for sending a mono signal to two different speaker sets, with separatelyadjustable level controls.

BRIDGED

•

mode (sometimes called Bridged-Mono — one or two inputs, one mono output) uses both sides of the amp to triple the power going to one speaker. An M•2600 in

BRIDGED

mode, delivers 2600

watts (into 4 ohms). Garsh!

Note: In

BRIDGED

mode, 4 ohms is the minimum speaker impedance you should connect to the amplifier. If you connect a lower impedance load, the amplifier may go into mode and the

• The XLR and TRS inputs for each channel are wired in parallel.

• The balanced XLR inputs are wired pin 2 = hot (+), pin 3 = cold (–), and pin 1 = shield (ground).

• The 1/4" TRS inputs are wired tip = hot (+), ring = cold (–), and sleeve = shield (ground), and can accept either balanced (TRS) or unbalanced (TS) cables.

Things You Must Remember:

• Never plug amplifier outputs into anything except speakers (unless you have an outboard box specifically designed to handle high-power speaker-level signals).

• Before making connections to an amp or reconfiguring an amp’s routing, turn the

GAIN

amp’s level (

) controls down, turn the power off, make the changes, turn the power back on, and then turn the level controls back up.

• If you shut down your equipment, turn off the amplifiers first. When powering up, turn on the amplifiers last.

• Save the shipping boxes! You may need them someday, and you probably don’t want to have to pay for them again.

USING THE CROSSOVER

The following three pages show how the internal crossover can be used to biamp your system. One amplifer plays the lower frequencies, while another plays the highs.

The electronic crossover inside the M•2600 splits the frequency band into two ranges, one below the crossover point ( one above (

HIGH OUT

). The

LOW OUT

) and

is available to the amplifier section for powering subwoofers. Both the

are switchable to the

OUT

LOW OUT

THRU

and the

HIGH

outputs, for sending line-level signals to the inputs of other amplifiers.

IT’S FREE!

The crossover has been carefully designed to give high quality, no-compromise performance, equal to external crossovers (without the extra cost). It uses a 4th-order Linkwitz-Riley design, with a slope of 24 dB/octave.

This amplifier receives the frequency

range above the first amplifier's

CROSSOVER point.

NOTE: Set its LOW CUT FILTER

below the CROSSOVER point of the

first amplifier or you will miss part of

the bass range.

Because the OUTPUT APPLICATION

switch is set to LOW OUT, this

M•2600 plays the frequency range

below the CROSSOVER point (60, 90,

or 120Hz).

Set the LOW CUT FILTER to the

lowest frequency your subwoofers can

handle (or set it to OFF).

Set the THRU switch to HIGH OUT

so the next amplifier will receive the

frequency range above the

CROSSOVER point.

Use the MONO MODE so the

subwoofers play the same and are

always in-phase. Low-frequency sound

is non-directional, so there is no

benefit in playing the subs in STEREO,

in fact, there may be times when the

speakers get out of phase, causing

some bass reduction.
