Sense Innovations ESS-ONE+ Real Engine Sound Simulator

REALISTIC RC ENGINE SOUND SYSTEM WITH CLASS-D AMPLIFIER, DNS/DCR ALGORITHM, AND DIY SCREW MOUNTING

The ESS-ONE+ by Sense Innovations offers an advanced sound upgrade in a compact housing for RC cars, trucks, scalers, and crawlers. Equipped with a redesigned speaker, optimized circuit layout, and an efficient Class-D amplifier chip, the module delivers higher power output, high sensitivity, and extended service life. Thanks to cutting-edge DNS/DCR algorithms, engine audio is dynamically generated in real time based on throttle stick position, rate of movement, and calculated engine RPM.

Compact Design, Dual Sound Switching, and Custom Mounting

Due to its compact dimensions, wiring inside the model can be routed neatly while saving valuable space. Four integrated threaded inserts on the back of the case provide flexible DIY screw-mounting options.

The system stores two complete engine sound profiles including customized braking, turbo, and tuning parameters, which can be toggled easily at the press of a button. An available AUX channel on the transmitter enables independent control of special sound effects such as horns or sirens. Through the Sense Innovations RC Plus PC software, users have access to sound downloads from the store, functional configurations, and lifetime firmware updates. The integrated power amplifier delivers up to 30 W and includes comprehensive protection against short circuits, overloads, and thermal overheating.

Operating & Mounting Instructions

• Throttle Calibration: Following initial connection, calibrate the unit to the transmitter throttle range (neutral, full throttle, brake) to ensure exact synchronization of engine audio with driving movement.
• AUX Channel Setup: To trigger special sounds like horns or sirens, connect the AUX signal lead to an open switch or momentary channel on the receiver.
• Chassis Mounting: Use the rear threaded holes or vibration-damping tape for securing the unit. Avoid covering the speaker cone to maintain optimal acoustic resonance.
• Moisture Protection: Shield the module and speaker cone from direct contact with water and mud.
