The DCI120-24 is a 24V, 120Amp controller and is ideally suited to use with one of our 24V DC large brushed motors or up to four of our 12V DC motors (In either parallel or series). It comes complete with a comfortable and easy to use handset that gives the user complete control over the motor and other auxiliary features. The DCi controller is waterproof and designed to last in real world, outdoor model engineering conditions. The TRUE TORQUE control system measures the current in the motor rather than the current from the battery. This allows for a huge leap forward in performance and control of the power in your model. Overloaded motors, excess heat and burnt brushes are now a thing of the past!

The digiSOUND702 is a phigh grade sound module for larger scale models that comes with a removable sound file, the engine sound is stored on a user changeable microSD card. This allows the user to swap and change engine sounds with any of the engine sounds available from the Mtroniks Ltd. sound library, these are available to purchase direct from the Mtroniks website.

Each of the different sounds available for use with the digiSound 702 come complete with an engine start up sequence, and engine shutdown sequence and a respective horn (if applicable). The horn sound and type will vary depending on the locomotive engine sound you choose. After the engine start sequence the sound module will track the speed of your locos motor and adjust the engine sound to suit the speed, giving a realistic, real world sound to your model.

The engine start, engine shutdown and horn functions can all be controlled by the DCi controller handset via the relay board supplied as part of this package.

The digiSound 702 comes complete with a built in and a high-quality speaker allowing for very realistic sound reproduction which us further enhanced by the addition of tone control.

All engine sounds are recorded from the original locomotives.
