OUTPUT CONTROL : This control determines the overall output volume level of the amplifier. After the GAIN Controls have been set

for the desired sound style and the three channels levels have been balanced with their respective channel MASTER Controls, the

 

 

OUTPUT Control allows you to change the playing volume level of the entire amp by adjust-

 

 

ing a single control. The OUTPUT Control is also wired as the Effects Loop Return Level

 

 

Control. Should you ever use your Nomad as a power amp alone by inserting a signal into

connected. It is wired in parallel to the OUTPUT Control and therefore also controls the vol-

NOTE: The Effects Loop RETURN jack can serve as a power amp input so that you may use

 

 

your Nomad as a power amplifier for either stereo reproduction or to incorporate additional

 

 

pre-amps. While the possibilities for this type of application are virtually limitless, there are a

few things to remember that will help you when interfacing to the Nomad for use as a power amp only;

1.) Connect “Dummy” plug or loose cable to SEND jack. ( This prevents any possible loading that could result in diminished RETURN sensitivity.)

2.) The OUTPUT Level Control will be the only active control on the Front Panel.

3.) The SOLO Control may be used to footswitch in a pre-determined amount of boost when the footcontroller is connected.

SOLO CONTROL : This control can only be activated if the correct Footcontroller is connected to the Footswitch DIN jack. SOLO is an additional final output level control wired in parallel with the OUTPUT Control. It is capable of a setting above that of the OUTPUT Control and can not be set below. The amount of apparent boost also depends on that of the OUTPUT Control - in that if the amplifier is at either the extreme low or extreme high levels of the OUTPUT, its effectiveness is

If the power section is either not a part of the sound (super quiet), or producing all its rated

wattage ( super loud), there is very little signal for the SOLO Control to work with. By using the

 

 

Footswitch and selecting SOLO, a pre-settable boost in overall level is possible on the fly...giving

 

 

you some control over your levels when it’s time to step out. Engineers may give you a bit of a

 

 

frown the first time you use it...but isn’t it time you heard yourself. It might even prevent them from

 

 

punishing you with the dreaded monitor or sidefill version of your tone.

Perfect for set breaks... this toggle switch also serves an even more important purpose. When the toggle is in the down

45, 55, 100 specifications

Mesa/Boogie, a name synonymous with innovation in the guitar amplification world, has carved out a niche in the hearts of musicians with its formidable lineup of amplifiers. Among these, the Mark series stands out, particularly with models like the Mark 100, 55, and 45. Each model brings its unique flavor and versatility, allowing players to craft their sound with precision.

The Mesa/Boogie Mark 100 is a powerhouse in the 100-watt category. It boasts multiple channels, allowing guitarists to switch between clean, crunchy, and high-gain tones effortlessly. One of its standout features is the onboard EQ, which facilitates fine-tuning for different guitars, pickups, and musical styles. The Mark 100 is engineered with Mesa's signature Dyna-Watt technology, providing a dynamic response at various volume levels without sacrificing tonal quality. This responsiveness makes it ideal for both live performance and studio recording, as it yields rich harmonic overtones and a wide dynamic range.

Moving to the Mark 55, this model offers a refined approach with 55 watts of power. It retains many features present in the Mark 100 but is more accessible for players who prefer a slightly lower wattage. The Mark 55 excels in mid-gain settings and is popular among blues and rock guitarists. Its Dual Rectifier circuitry can dial in everything from smooth, bluesy overdrive to tight, aggressive rock tones. The amp also incorporates a versatile effects loop, providing seamless integration with pedals and processors, making it a favorite among pedal enthusiasts.

The Mark 45, perhaps the most compact of the trio, brings 45 watts of power to the table, making it a versatile choice for players seeking portability without compromising tone. It retains critical features such as multiple channels and a powerful EQ section while being lighter and easier to transport. The Mark 45's sweet spot is found in its ability to deliver rich, saturated tones at manageable volume levels. Often favored for intimate gigs and home recordings, its versatility allows players to explore genres from jazz to metal with equal flair.

All three Mesa/Boogie amplifiers utilize high-quality components designed for durability and peak performance. Their construction is robust, ensuring reliability on stage or in the studio. With advanced features such as power scaling and tube rectification options, musicians can tailor their sound precisely.

In summary, the Mesa/Boogie Mark 100, 55, and 45 each present guitarists with distinctive tonal characteristics and features that enhance playability and sound. From the powerful performance of the 100 to the compact yet versatile 45, these amplifiers deliver the high-quality, rich tones that Mesa/Boogie is renowned for, catering to the diverse needs of players across genres.
