The rotary encoder seamlessly fits into any standard rocker switch slot that gives your cockpit a clean feel with a small foot print. The intercom module is tucked away under the dash, on the firewall, in the glove box or attached to the console keeping the side-by-side sleek while shielding the intercom from damage. Don’t let its compact size fool you—the S4S Rotary Encoder is packed with powerful features. With five intuitive menus, you can effortlessly manage four independent volume controls, adjust VOX settings, utilize half VOX for quick communication at idle after high RPMs, and control your Bluetooth music and volume—all through one simple rotary encoder. With all these menus in one simple to use interface it is “one knob to rule them all”.

Unrivaled Stereo Sound
The S4S delivers premium stereo sound, Bluetooth 5.0 connectivity, standard 3.5 mm connections, and audio out for external speakers or recording devices. Its VOX system offers 32 steps to keep your mic closed when not in use, while four independent volume controls (expandable to eight headsets) ensure everyone can enjoy their preferred volume level.
The S4S takes audio quality to new heights with its rare and coveted stereo sound upgrade. Voice transmissions are optimized for clarity at the ideal frequency, while your phone simultaneously delivers high-quality stereo music. The result? Crystal-clear voice communication paired with headphone-like music quality—the best of both worlds and the highest audio fidelity of any off-road system available.
Smart Musi Mute & Phone connectivity
Love blasting your tunes? The S4S has you covered. When someone speaks—whether in your vehicle or over a 2-way radio—the music automatically mutes to prioritize the message. Once the conversation ends, your music resumes at its preset volume, keeping the good vibes going.
Connecting your phone to the S4S is a breeze via integrated Bluetooth 5.0. With cell coverage, your favorite off-road toy gains the same hands-free calling capabilities you enjoy in your daily driver. A 2-second press in any menu brings up your Google or Siri assistant.
Additional Volume & Advanced Vox Technology
For riders with hearing difficulties or those in extremely loud machines, the S4S shines. While most users find comfort in the 4–5 click volume range, this system cranks up to level 16, ensuring audibility in even the noisiest conditions. Pair it with our black ops headsets for optimal performance.
Our Voice Operations Exchange (VOX) system keeps headset mics off until someone speaks, eliminating background noise and delivering pristine audio for radio transmissions and music. Unlike other intercoms with limited VOX tolerance, the S4S handles high-speed noise with ease, keeping mics closed until you’re ready to talk. Plus, real-time sensitivity adjustments with precise incremental steps ensure your mic opens exactly when you need it—say goodbye to missed first words.
Elevate your off-road experience with the COM S4S Rotary Encoder—where cutting-edge technology meets unbeatable sound.
Button setting memory
Once you get the VOX and volumes set, the S4S will keep that setting even when the device is turned off.
Weatherproof
Can it Handle Water?
Don’t pressure wash any electronics up close, but the rotary encoder solid front faceplace means water splashing from rain/snow and machine washings won’t be a problem.
Specialty Connections = Special Orders
Accidentally damaging a wire during a ride no longer mean communications are down. With the S4S, you can simply make a run to any electronics store to pick up a temporary replacement 3.5mm TRRS cord.
Expandability
Maximum number of seats
Adding an extra headset is easy. Each of the 4 volume controls can be split 1 time. Simply add a splitter to the end of the 3.5mm cord and plug in the additional headset.
Interface with External Speakers
The S4S provides a 3.5mm analog audio out on the back. Plugging into it will simultaneously broadcast the sounds you hear in your headset to 1 (or more) external speaker(s). Interfacing can be as simple as plugging a standard 3.5mm cord into the “aux in” port of the portable Bluetooth speaker you use around camp. Or go all in and obtain a 3.5mm-to-RCA cord to turn S4S into the head unit for your impressive amplified speaker system. Either way, the final result will be audio broadcasting from your machine. Any music will auto mute (just like it does in your headsets) and play any 2-way radio transmissions.
