The ESS-ONE+ Engine Sound System lets you choose from multiple throaty race engine sounds, shifting, brakes, and turbo blowoff valves! The programmable ESS-ONE+ delivers these sounds in one simple, small box for a clean and easy installation. Whether you drive a short course truck, drift, F1, or rally car, the ESS-ONE+ has the right sound to match!

ESS-ONE+ uses an advanced DNS/DCR algorithm to reproduce the sound of real engines. The sound is real-time calculated based on the throttle input + throttle movement speed + engine speed to closely simulate real engine sounds. This creates a richer sound than could be had through the throttle alone.

ESS-ONE+ supports the AUX channel which can simulate a variety of sounds. Special sounds, like a car alarm and horn, can be independently controlled by a third channel on the transmitter.

ESS-ONE+ supports fast switching between two sets of engine sounds. Users can install two different sounds having different brake and acceleration settings into the ESS ONE+, and the sounds can be easily selected with the press of a button.

ESS-ONE+ supports firmware and function upgrades. Sense Innovations supports the software-download services of RCPLUS to provide continuing firmware and software updates. Users will receive ongoing software upgrades.
