The M3000 is a dual channel power amplifier, rated for a maximum power output of 3000 watts in bridged mono mode, or 1500 watts per channel when driving a pair of 2 ohm stereo speakers. Mackie has designed the M3000 to be used either in studios or in concerts, giving it a dual variable speed fan cooling system that remains off when the amplifier is idle or operating at low volumes. At high volumes, the amplifier’s three rail Class H circuitry engages, allowing power to be drawn equally across these multiple rails (The M2000 only has two rails), maintaining that same level of efficiency across the amplifier's entire volume range. This extremely efficient operation greatly extends the expected life of the power amplifier, allowing Mackie to offer a limited five year warranty against defects or equipment failure for each unit.
At the rear of the unit are two switches for each amplifier channel, allowing 150 Hz crossover and signal limiting to be independently engaged or disengaged on a per-channel basis. The crossover feature allows the amplifier to easily be used to drive both a subwoofer and main speaker simultaneously, or to drive a single bi-amplified speaker. Multiple M3000 units can also be used in tandem, to drive a maximum of 24 bi-amplified speakers in a very large or outdoor concert environment. Signal limiting can also be enabled or disabled on each channel. This technology allows the amplifier to easily pass transient attacks such as a particularly hard snare drum hit or bass pop, by transparently reducing the volume level to prevent clipped waveforms from reaching the speakers.
Mackie has been well known in the music industry for many years as a top provider of sound equipment for recording studios and live concerts. With its M-series of power amplifiers, Mackie has brought some of this studio technology to the live stage, giving musicians a new level of sound quality and efficiency that they may not have previously expected from a power amplifier. Mackie M3000 Power Amplifiers are the midrange offering in this series, featuring even more wattage and greater efficiency of power usage than the M2000.
The M3000 features a solid rackmount construction, with a weight of 48 pounds. Its high level of efficiency ensures that it will be able to power your next all day concert event at any venue without breaking a sweat.
Mackie M3000 Power Amplifiers - Summary:
* Rated for a maximum power output of 3000 watts (mono, bridged), or 1500 watts per channel when driving a 2 ohm speaker load
* Independently selectable 150 Hz crossover allows the easy operation of bi-amped speakers or a subwoofer and main speaker simultaneously
* Transparent limiting reduces the amplitude of transient attacks before they can cause speakers to clip
* High efficiency design allows studio installations to operate in near silence, or all day concert events at loud volumes
