BASIS M 2000

Description:

By now you see the M-2000houses two completely different pre-amplifiers, one all tube, one FET. These may be footswitched between and/or combined by utilizing the Mix Mode, in which any blend of the two may be created. The Tube Channel offers the choice of a normal (low gain) mode operation and an all tube Hi Gain overdrive mode for wilder applications. Each of these pre- amps offers the full array of rotary style tone controls, producing a rich, warm blend...fast! Each Channel may then be further customized by engaging its own nine band graphic equalizer. These channel specific EQ's may be triggered in three ways: 1. Via the front panel's mini toggle switch 2. Via the foot controller and 3. Programmed to engage in the Mix Mode automatically. Both EQ's, as well as the modes, can be triggered remotely by using most tip to ground switches, such as the kind found on many Master Rack Control systems. These ports appear as 1/4 inch jacks found on the rear panel in the External Select section.

Each channel also houses a Frequency Activated (shelving type) Compressor that can be bypassed or applied in 3:1 and 5:1 ratios. The M-2000is fitted with a parallel effects loop with a crossover enabling frequency specific effect placement as well as a dry/wet blend control. This loop may be assigned to auto engage in any or all of the modes as well as bypassed. This crossover can also be used to send a pre-amp signal of a selected frequency to another power amplifier for bi-amping. A Balanced Output with pre and post EQ positions and a level control is provided for recording or live sound reinforcement applications. An output for a Tuner is included and may be triggered remotely by the Gain switch on the Foot Controller.

The M-2000'sSimul-State power section feeds two mono 1/4 inch jacks or two 3-pin XLR jacks to deliver a robust 600 Watts RMS into 4 Ohms which is the recommended load. The toneful Simul-State circuit uses a 12AX7 driver tube to feed the power block of 12 high quality mosfets. This design boasts the smooth warmth found in all tube circuits and the tight, immediate response often associated with solid state amplification. As you can see, the M-2000has all the needed features to elevate your playing to new plateaus, yet it remains simple and straightforward to use. The following is an explanation ot the controls and a few setting examples.

M 2000 specifications

The Mesa/Boogie M 2000 is a highly regarded tube amplifier that embodies the rich legacy of Mesa/Boogie, a brand known for its unique sound and innovative designs. Introduced in the late 1990s, the M 2000 was part of a shift towards more versatile and high-powered amplifiers, catering to both live performance and studio recordings.

One of the standout features of the M 2000 is its dual-channel design, which allows for a broad spectrum of tonal possibilities. Each channel offers independent gain, treble, mid, bass, and presence controls, enabling the player to sculpt their sound with precision. This flexibility is particularly beneficial for guitarists who require a range of tones, from clean and glassy to aggressive and distorted.

The M 2000 is equipped with Mesa/Boogie's patented Dyna-Watt power technology, which delivers an impressive 200 watts of power while maintaining a light and compact chassis. This technology enhances headroom and responsiveness, emphasizing the tonal characteristics of the tubes and enabling them to react dynamically to the player's touch. The result is a natural and expressive playing experience that can adapt to various musical styles.

Another key characteristic of the M 2000 is its built-in reverb, which adds depth and dimension to the sound. Players can select between a lush spring reverb or a more subtle hall effect, further enhancing the amplifier's versatility. The inclusion of an effects loop also opens up new possibilities for integrating pedals and external effects, making it an ideal choice for musicians utilizing multiple effects in their setups.

The cabling and connectivity options on the M 2000 are designed to suit both studio musicians and touring artists. It supports multiple speaker configurations and features parallel effects loops, ensuring seamless integration into any rig. Mesa/Boogie's reputation for durability is evident in the construction of the M 2000, with high-quality components and a rugged design that can withstand the rigors of the road.

In summary, the Mesa/Boogie M 2000 is a powerhouse amplifier that offers superb tonal flexibility, advanced power technology, and durable construction. Its combination of features makes it an excellent choice for both professional and aspiring musicians looking to elevate their sound.
