QSI Quantum Engineer
Analogue sound controller for QSI Quantum decoders

Quantum locomotives are equipped with QSI QARC™ (Quantum Analogue Remote Control) Technology, uses special remote control signals to operate different Quantum features without the need for digital systems like DCC.
Adding the Quantum Engineer to your existing Analogue power pack allows you to operate features that are otherwise available only in DCC plus additional features that are not yet available in DCC!

• Turn On or Off Lights including Headlight, Reverse Light, optional Cab Lights and Number Board Lights. In addition, you can turn on or off optional Hazard Lights (Mars or Ditch-lights) plus switch them to be on steady or strobing.
• Shut Down and Start Up Locomotives. Complete Shut Down takes the engine off-line where it will not respond to either the throttle or other commands. Two types of Shut Down and Start Up scenarios are available; a short version where the Start Up and Shut Down effects take very little time or extended scenarios which includes locomotive preparation and/or maintenance effects.
• Operate Prototype-like Air Brakes. The Apply Brakes button results in the engine sounds reducing to idle while you hear the hiss of the air-line pressure progressively decreasing causing the engine to slow. You control the amount of air pressure and amount of braking effect. The Release Brakes button causes the engine sounds to return to normal as the locomotive’s speed gradually increases back to its original setting.
• Turn on Dynamic Brakes. Press the Dynamic Brakes button and hear the diesel motor reduce to notch 1 while the sounds of the powerful Dynamic Brakes and Cooling Fans turn on. Press the Dynamic Brakes button again to turn Dynamic Brakes off while the engine sounds return to their original power level.
• Change System Volume while Train is Operating. The engine volume can, of course, be set with manual volume control or through programming. The Quantum Engineer allows you to change volume up or down at the touch of button whenever the locomotive is operating. Mute Engine Sounds while Train is Operating. Presses the Mute button to gradually reduce the volume to a lower level or increase it gradually back to normal. This feature is valuable to lower the sound to allow answering the phone or to have a conversation but also as a way to easily lower the sound of engines in the background area of the layout or increase the sound volume as the engine moves to the front of the layout.
• Disconnect the Motors. TThe Disconnect button turns the motor drive off allowing you to operate the throttle without the engine moving. You can rev the diesel engine or vent steam through the throttle on steam locomotives. You can even apply Dynamic Brakes to allow the engine to operate under laboured conditions – a common practice on prototype diesels to test the motor/generator output.
• Put the Engine in Standby./span> The Standby state allows the engine to remain at rest in a low idle condition, which is ideal for unmanned powered locomotives waiting on sidings. In Standby, locomotives will not respond to throttle or most other command buttons. This allows you to operate other locomotives on the same power grid without the standby engines responding. Standby engines come back to life by pressing the Start Up button.
• Quickly Change between modes of Throttle Control. There are separate buttons for STC (Standard Throttle Control) and RTC (Regulated Throttle Control). When you want to operate your engine in a prototype manner, use the RTC button and when you want a responsive engine, press the STC control.
• Add Load and Heavy Load. Use the Load button in Neutral to turn on or off the Load value you have selected in Load programming. This button also acts as a “Heavy Load” command when the engine is moving. This causes the engine’s speed to change very slowly when moving around the layout, up and down grades, etc. and allows you to use the throttle to produce exaggerated Sound of Power™ effects when working hard or low laboured sounds when coasting to a stop or going down grade.
• Hear Status Reports./span> In Neutral, pressing the Status button verbally reports the throttle type (RTC, STC), the amount of Load, whether the Load is on or off, and the Disconnect, Standby or Shut Down condition. While moving, the Status button reports the speed of the locomotive in smph (scale miles per hour).
• Access Quick and Easy Programming. Enter programming by holding Mute/Prog button down while you turn power on. The power light will blink. Move through the different Program Options (POP’s) by using the Next button to advance or the Prev to go back to previous POP’s. Use the up or down Arrow buttons to make changes at any POP.
• Operate many Other Features. Buttons are available to operate Doppler, to blow an automatic horn or whistle sequence of two longs, one short and another long for Grade Crossing warnings, to sound Brake or Flange squealing, to sound coupler opening or Coupler Crash sounds.

Wiring is Simple
Two red wires go the variable DC output from the power pack and two black wires go to the track. All features on the power pack remain the same including throttle and reverse switch control. It takes less than five minutes to add Quantum Engineer to your existing power pack.

Operation is Simple
Quantum Engineer allows customers full access to all the Quantum features without having to migrate to Command Control. Every feature is now available at the press of a button.

QQuantum Engineer Controllers are designed to easily and quickly operate locomotives that have QARC (Quantum Analogue Remote Control) technology.

The Quantum Engineer buttons are organized by function to make operation simpler. The buttons on the right are the Primary Control Keys for engine operation and include horn, bell and brakes./p>

The set of fifteen gray keys to the left of the Primary Control Keys, are the Locomotive Feature Keys, and provide operation of different engine settings such as lights and fans, as well as controlling different effects like Doppler and Squealing Flange sounds.

The cluster of five keys in a star pattern in the upper left corner are used for two different types of control. During operation, the vertical Arrow keys control sound volume, and the left/right arrow keys select the Throttle Mode. During programming, the arrow keys select the different program options and allow you to change the settings. This group of five keys is called the Star Pad Keys.

The keys in the lower left are used to control the locomotive states of Start Up, Shut Down, Disconnect and Standby as well as locomotive Status reporting. This group is called the Locomotive State Keys.
