Prosound429 Platinum Thumper

With the Prosound429 Platinum Thumper being the most powerful thumper available from Clark Synthesis, it is the clear choice for inclusion in our Prosound Package. The Prosound429 Package consists of (1) Prosound429 Platinum Thumper, (1) TC-101 Amplifier Interface with (2) Speakon Connectors, (1) Gig Bag, and all of the hardware necessary for mounting it to a drum throne or platform.

The Prosound429 Platinum Thumper is the most powerful thumper available from Clark Synthesis. It is the first choice for many professional touring musicians.

Originally developed for military simulation devices, the Full Contact Audio® Professional Transducers were specifically designed to transfer sounds like gunshots and explosions into a tactile experience that can be felt as well as heard. This technology transferred to the music industry, and every knowledgeable drummer or sound stage touring manager will choose Clark Synthesis Professional Transducers over any other option due to their amazing performance quality and reliability. The TC-101 serves as a protection device to limit peak signals.

The Prosound429 Platinum requires an amplifier for operation. Clark Synthesis recommends an amplifier stable at 4 ohms that can deliver 125-150 watts @ 4 ohms (per transducer).

From professional installers to Do-It-Yourselfers, our customers love Clark Synthesis products for lots of reasons. For this blog, I want to focus on one of those reasons – how Clark Synthesis values our customer’s time. I wish all other companies would value their customer’s time.   Years ago, we sat down and figured out what mounting hardware was needed for over 98% of the applications that use Clark Synthesis Transducers.

Jim Riley, Drummer & Bandleader of Rascal Flatts, endorses Prosound429 Thumper – “A Great Sonic Experience”

By |October 29th, 2020|

We are excited to announce that Jim Riley, drummer, and bandleader for Rascal Flatts, has signed an endorsement deal with Clark Synthesis. For close to 20 years, Jim has toured with Rascal Flatts using the Prosound429 Thumper. “I started using them in the early 2000s and I haven’t looked back. I’ve had them on every touring kit that I’ve ever had.”  [...]

Prosound429 Thumpers provide tactile monitoring for musicians and vocalists while also reducing stage noise.

Some guitarists will build a wedge for the stage and put a Prosound429 Thumper in that wedge. They can then place their foot on the wedge to feel the beat.

Wherever the musicians are on the stage, a Prosound429 Thumper is mounted in their seating  or under the stage. This makes it possible for all of the musicians to perform perfectly in sync.

Drummers mount The Prosound429 Thumper to their drum thrones for direct tactile feedback. The Prosound429 eliminates the need for feedback speakers. This help save a drummer’s hearing and reduces stage noise.

Pianists mount Prosound429 Thumpers under their bench. Now the pianist doesn’t have to have endure the kick drum in their in-ear monitors.

Yes!  Clark Synthesis TSTs are used in therapy chairs, therapy beds, massage tables, etc. If you do a Google search for Vibroacoustic, you will find many products that contain Clark Synthesis TSTs.

Clark Synthesis Tactile Sound Transducers (TSTs) transform pure audio as electrical energy into pure audio as vibrational energy.  TSTs are much more than shakers.  Shakers only make things shake.  TSTs faithfully reproduce audio signals bringing new levels of realism and enjoyment to VR spaces, Home Theaters, Simulators, Movie Theaters, etc.

Yes. Be sure to wire the TSTs in-phase so they all work together.

Ventilation is not always required. However, warmer climates and environments may require ventilation. Contact Clark Synthesis for specific recommendations.

We recommend 3 inches of clearance.

We recommend 16 gauge wire for up to 50 feet of length; 14 gauge wire for 50 feet to 150 feet; 12 gauge for distanced greater than 150 feet.

This means both TSTs are wired the same way to the amplifier.

A Thumper is a TST designed for the Prosound market – The Prosound429 Thumper.  The The Prosound429 mounts under a drum throne, piano stool, the stage, or a platform. The kick drum is often routed to the The Prosound429 so musicians can feel the beat and play perfectly in sync.

Tactile Sound is pure audio that is felt through touch and is heard through bone conduction.

We recommend a 125 watt amplifier at 4 ohms for the TST239 and a 150 watt amplifier at 4 ohms for the three-series and four-series TSTs.

We recommend the TST329 Gold TST for dirty environments. We recommend the AW339 for dirty environments that may be extremely damp.
