Features Common to Analog and DCC

• Downloadable sounds and software enabled to allow future sounds and code
  improvements to be installed in locomotive without removing the memory chip. (Requires additional download module to be connected between your PC and program track; to be announced).
  
• Back EMF Load Compensated Speed Control. This feature had not been previously available in Analog or DCC.
  
• Improved sound profiling allows individual sounds to remain audible even at low system volume settings.
• Added Individual sound volume settings including 1) Horn, 2) Bell, 3) Motor, 4) Fan, 5) Turbo, 6) Air Brakes, 7)  Air Pumps, 8) Air Let-off, 9) Short Air Let-off, 10) Squealing Brake/Flange, 11) Dynamic Brakes, and 12) Coupler Sounds.
• Sound of Power™ added to simulate increased power demands under acceleration and decreased power under deceleration.
• Synchronized steam dynamo sound with headlight turn on operation.
• Progressive shutdown capability including states of Disconnect, Standby and Total Shut Down. Available for DCC and DC (with QARC Technology and Quantum Engineer)
• Extended Shut Down Scenario. Available in DC with QARC Technology and Quantum Engineer.
• Start Up
• Extended Start Up Scenario. Available in DC with QARC Technology and Quantum Engineer.
• Functional Air Brakes to slow train with added brake squeal and air-line let off sounds. Available in DCC and DC with QARC Technology.
• Verbal Status Report of locomotive state. Available in DCC and DC with QARC Technology.
• Play Horn or Whistle with alternate endings. Available only with sound sets that have sound records of different horn and whistle endings.

Features in Analog

• Regulated Throttle Control with real inertia effects. There have been many improvements in Regulated Throttle Control since its introduction.
  
• Separate sound records for Horn hoots and Whistle hoots.
  
• Load settings allowing up to 15 levels of inertial.
  
• Special Heavy Load option allows near constant momentum of trains up and down grades.
  In Heavy Load, the throttle will increase or decrease motor revs and Sound-of-Power™ without noticeably changing the locomotives momentum which allows operator to individually control locomotive motor RPM and sound settings during operation. QARC only.
  
• Selection of helper type locomotives including Normal, Lead, Mid, End and Pusher type helpers.
  
• Direction setting for improved lighting control of locomotives in consists.
  
• New accurate way to set V-Start.
  
• Improvement in changing direction in Neutral to provide three hoots when moving in reverse and two hoots when moving to forward.
  
• QARC™ Technology added. Quantum locomotives not equipped with new QSI QARC™ (Quantum Analog Remote Control) Technology can now be upgraded.

Aftermarket HO DC/DCC Sound Decoder System
Quantum Revolution has been developed for installation in existing non-sound HO engines. By taking the large capacitor off the board, making the unit smaller, adding components to keep the board running cool, and giving customers options for CAM or Back EMF motor speed detection as well as programming for different speaker arrangements, we can offer the proven QSI Quantum System in a package that will be easier to install in more engines.

QSI Revolution-A (Atlas format) - shipping in May.
QSI Revolution-U (universal format) - shipping TBD.
