We would like to congratulate you on the purchase of your new Nomad Amplifier. If you have not yet realized the power and versatility of this instrument, we hope this manual will provide an enjoyable tour through the many stylistic regions this exciting platform was born to roam.
Your Mesa/Boogie Amplifier is a professional instrument. Please treat it with respect and operate it properly. USE COMMON SENSE AND ALWAYS OBSERVE THESE PRECAUTIONS: Do not expose amplifier to moisture, rain or water , direct sunlight or ex- tremely high temperatures.

Nomad amplifiers are available in many configurations in terms of power / speaker combinations, as well as “head only” formats. All Nomad amplifiers share basically the same pre-amp and since most M esa/Boogies are available in many choices as to power and speakers, for all practical purposes, Nomad refers to this pre-amp.
Channel 1 switched to PUSHED reveals a much gainier region, perfect for all types of dirty chording or can be maxed for urgent high gain soloing. Channel 2 may be switched down to MODERN to unleash a tighter , meaner nature that works great for crunch rhythm or searing solo sounds.
The NOMAD 55: represents the deal of the century with its robust 55 watts produced by two 6L6 pentodes. With ample headroom for clean styles and a slightly brighter , more aggressive nature than its bigger brother the Nomad 100, the 55 lives in the region many players consider the perfect wattage arena.
No matter which of these many Nomad platforms you have chosen, the basic operation is the same and the experience playing them is oo...fun and exhilarating. Before we get to specific Controls and Channels, here are some tips to get you playing and enjoying your Nomad right away; (1.
PA G E 5 Quick Demo Settings: Before we get to each individual control and how they interact with each other , there is one thing they all have in common.
PA G E 6 The Controls: (Continued) GAIN : This control adjusts the predominant gain stage in each channels’ circuit with the function and taper being optimized for each individual channel.
MASTER : This control is the master feed from the end of the pre-amp to the driver stage and the Effects Loop. As you can see each Channel is fitted with its own MASTER Control, enabling the three channels relative volumes to be matched regardless of their extremely different sound styles and gain signatures.
TREBLE : ( Continued) The one place you may want to throw caution to the wind and set the TREBLE Control above this median zone presents itself in Channel 1. In both modes ( Clean & Pushed ) the TREBLE Control can be used to dump extra gain into the mix.
PA G E 9 BASS: ( Continued) The Bass frequencies are, as we mentioned, different in each channel and appear as follows: CHANNEL 1: Enhanced low and sub-low regions provide warmth and most importantly , breath for clean sounds which produces a bouncy , elastic feel and natural sounding fundamental, yet with plenty of air .
P AGE 10 Channel Modes: (Continued) PUSHED: This mode is a radical departure from the sweet shimmering blend of the CLEAN / NORMAL modes low gain character .
PA G E 11 5 BAND GRAPHIC EQUALIZER : ( Nomad 100 Only ) If you have purchased the Nomad 100 you have probably already realized that the bonus gift of the On-Board 5 Band Graphic Equalizer is well worth the omission of the beautiful, but stoic, Nomad logo .
PA G E 1 2 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 h.
P AGE 13 AC MAINS : This switch delivers the A.C. power to the Nomad. Make sure the unit is grounded (all three terminals of the A.C. power cord must be connected whenever possible to avoid injury to the user as well as to the unit) and that the proper voltage is present.
FOOTSWITCH SOCKET : This 7 Pin DIN type socket located on the underside of the chassis accepts the Nomad Footcontroller cable. T o use the Footcontroller to select the channels and features; 1.) Connect the Footcontrollers’ attached cable here by lining up the tab on the cable with the detent on the cable sleeve.
P AGE 15 REAR PANEL CONTROLS & CONNECTIONS: (Continued) RECORDING OUT : This 1/4” jack captures the sound of your Nomads’ pre-amp and shapes the sound, enabling direct insertion into a console for both recording and live reinforcement applications.
SEND, RETURN & FX MIX: Y our Nomad is fitted with a parallel effects loop to provide optimum interfacing of outboard signal processing. In this way the maximum amount of pure amp signal with its attack character and warmth is retained because a large amount of dry amp sound can be mixed with a small amount of a very wet processed signal.
P AGE 17 REAR PANEL CONTROLS & CONNECTIONS: (Continued) 50 / 100 WATT : (Nomad 100 Only) This is the “half power” switch found only on the 100 watt Nomad. The two inside power tubes are put in a standby mode when the 50 watt position is selected reducing the RMS power to approximately 50 watts.
P AGE 18 REAR PANEL CONTROLS & CONNECTIONS: (Continued) SLAVE TO POWER AMP CH2 CH1 REVERB 4 OHM SLAVE: This jack captures a signal directly from the speaker jacks and is “padded” to provide a way to use the entire sound ( pre- amp & power stage ) and send it on to other power amplifiers.

TUBE NOISE & MICROPHONICS Y ou may occasionally experience some form of tube noise or microphonics. Certainly no cause for alarm, this quirky behavior comes with the territory and the T one.
P AGE 30 DIAGNOSING PRE-AMP TUBE PROBLEMS: Because your amplifier is an all tube design, it is quite possible that you will at some point experience minor pre-amp tube noise. Rest assured - this is no cause for alarm and you can take care of the problem yourself in a matter of minutes by simply swapping tubes.
P AGE 31 BIAS ADJUSTMENT: (Part of a continuous series) An Article written by Randall Smith that we thought you might find interesting. Here’s a question we often hear: “Why doesn’t M esa put bias adjustments in their amplifiers?” Well, there’ s a short answer and a long answer to this question.
P AGE 32 BIAS ADJUSTMENT: (Continued) When you scrape your feet across a carpetted floor in dry , wintery conditions, your body can become charged with 50,000 to 100,000 volts of static electricity .
P AGE 33 BIAS ADJUSTMENT: (Continued) But don’t these alterations imply that you are second-guessing the amp designer and that there’s a better set of operating conditions that the designer missed.
IMPEDANCE: Wiring up speakers to provide the most effective load and making sure that all of them are in phase will help in creating the best sound possible. This is not too difficult, as long as you understand a few things about loading and how to connect you r speakers to provide an optimal resistive load.
P AGE 35 PARALLEL: When wiring in parallel, the resistance of the speakers decreases. T wo 8 ohm speakers wired in ( hooked-up ) Parallel results in a 4 ohm load. It’s easy to calculate the ef fect of a resistive load when all the speakers are all the same resistanc e.

With apologies to Friends and Relatives from the Emerald Isle - who will make their appearance soon enough - the humor which follows is dedicated to the memories of Spec McAuliff and Fae (Rafael) McNally , two of the True Greats.
Thus a diode tube - one with a cathode and an anode - is mostly used to rectify alternating current into direct current by passing it without restriction, but in one direction only .
PENTODES: (Continued) Thus the proper cocktail waitress - visible through the louvers - is scantily clad so as to be all the more effective at reinforcing the attractive influence of her bar and by being located in between the door and the bar , she serves as bait to lure customers past the door ’ s negative influence.
