Introduction Congratulations on your purchase of an Atomic Reactor 112, a major step in bringing vacuum tube analog musicality to the digital world. The Reactor 112 is an extremely versatile musical instrument that provides a live performance platform for your modeling tools and instrument processors. The Reactor 112 is clearly different from other guitar amplifiers. What we would like to accomplish in the following pages is to bring you up to speed on exactly how and why we made it that way.
Getting Started Unpacking If you are reading this manual you have probably already opened your Reactors shipping carton. Now would be a good time to familiarize yourself with the things that are inside the carton. What’s in the Box Every Reactor 112 comes from the factory shipped complete with a DS-1 docking unit and the following items: 1. Owners Manual 2. Product Registration Card Packed with the DS-1 1. One (1) AC line cable for proper usage in the country of purchase. 2.
[ Controls & Connections (Top) Z X \ ^ Y X POWER: ] The power switch turns the power OFF & ON to the Reactor 112. It also acts as the master power switch for the modeler when connected and housed in the DS-1 (see page 6). Y INPUT: This is where you plug in your instrument cable when docking a modeler inside the DS-1. NOTE! When using a modeler outside of the DS-1, such as a Rack-mount or floor based modeler, the instrument should be connected to the modeler per the modeler’s instruction manual.
Controls & Connections (Rear) [ \ ] EFFECTS LOOP RETURN SEND - L X MODEL REACTOR 112 Atomic Amplifiers LLC. Orange CT. !CAUTION! FUSE SEND - R X VOLTAGE SELECTOR SWITCH: Y ^ 0101010101 Z The Reactor 112 has a voltage selector switch and can be used in most countries. The switch selects between 115Volts (US use) and 240Volts (European use).
The DS-1 Atomic’s philosophy is to afford its’ customers the opportunity to choose the brand of modeler or preamp that they prefer, and thus enjoy the sonic characteristics that they demand. The DS- 1 allows Atomic Reactor Series amplifiers to act as a platform for select digital amp modelers and other types of related equipment. When using a modeler installed in the DS-1, all of the signal input and output as well as the power supply connections are made (see page 5).
Installing a Modeler into the DS-1 X Y Screw the 3 thumbscrews labeled “A”, "B” &”C”, into the corresponding holes located on the bottom of the DS-1. Attach the 3 rounded mushroom heads caps to the ends of the locking screws. * *A set of mushroom heads come shipped with each Reactor 112. Z Position the proper docking template on the top of your modeler. [ Insert the docking template along with the modeler into the rear of the DS-1, locating and positioning it in the notch of the template frame.
Basic Set Up X Y After obtaining the proper template load your modeler into the DS-1 provided with your Reactor 112. (Make sure the modelers power switch is set to on.) Load the DS-1 into the docking bay located in the top of your Reactor, making sure that the dock locks click into position. Once loaded properly the audio and power connections are made between the Reactor and the DS-1.
Expanding Your Rig Installing a Blank Template into the DS-1 X Y First locate the 8 screws attaching the template frame to the top of the DS1. There are 4 screws that come in groups of 2 on each side. Remove these screws (and don’t lose them!) using a properly sized Phillips-head screwdriver. Remove the template frame of the DS- 1 Still got the screws? Z Replace the template frame with a blank template (Atomic Part # ATBLANK – purchased separately). Still got the screws? [ Replace the 8 screws.

Tips & Insights Your Modeler’s Settings: The Reactor 112 was designed to bring out the very best in your modeler. Atomic recommends that in order to achieve the best sounding results, modeler’s should be used in their “direct” mode. To achieve the most realistic/natural amp and effect sounds, cabinet and mic simulations can stay “on” but room levels should be turned “off” or be set to 0% and mics should be positioned “on access”.
Downloading Custom Tones: The Reactor 112 was designed to bring out the very best in your modeler. That means the one you own. As the Reactor has become the industry standard for taking modeling tools live some manufacturers have expressed interest in developing presets for their modelers that are Reactor specific. Since the DS-1 and the Reactor were designed as a “platform” for different types and brands of modelers we welcome these efforts to improve your playing experience.
Good Housekeeping Output Tube Bias Your new REACTOR 112 has an internally mounted variable bias control. The bias control is used to set the idle current in the output tubes, properly matching amp’s performance characteristics to the type of tubes used. Each different tube brand and manufacturer may require a slightly different bias setting. An amp’ s bias can drift over time as well as the tubes bias requirements may change with extended use.

Trouble Shooting Reactor does not power up. 1) Is the power cord properly plugged into an electrical outlet? 2) Is there power at the outlet? 3) Is the power cord firmly inserted into the AC input socket on the rear panel? 4) Is the fuse blown? The Reactor powers up but the modeler does not.
