Description
Clara Dmaj - 8 x AES/EBU I/O PCIe card, 24 bit 192KHzIn the space of just one PCIe slot width, the Clara Dmaj provides the connection for 32 audio channels. The AES EBU inputs and outputs 1 to 4 as well as a word clock input are located on the motherboard. Connectors 5 to 8 break out on a D Sub connector which has no active electronics. Consequently, it can freely be placed in the computers case, separated from the motherboard. Or it may take any place next to other PCIe components with the slot

The AES/EBU inputs and outputs 1 to 4 as well as a word clock input are located on the motherboard. Connectors 5 to 8 break out on a D-Sub connector which has no active electronics. Consequently, it can freely be placed in the computer’s case, separated from the motherboard. Or it may take any place next to other PCIe components with the slot bracket.Precision Clock
The internal clocking of the Clara sound system has an amazingly low jitter of less than one nanosecond. This is beneficial to the audio quality of the system and that of any connected digital device. Often the clock of the Clara D is many times more precise than the internal clock of the connected device and thus makes the purchase of a separate clock generator unnecessary.
The highest Audio Quality
The Clara Dmaj is the elegant partner for pure digital signal processing of many AES/EBU signals. HD audio quality with 24 Bit and sample resolutions of up to 192 kHz guarantee a pristine sound. High-quality sample rate converters provide flexible clock management while maintaining a full dynamic range of 144 dB.
Switchable Sample rate Converter (SRC)
The SRCs, which can be switched on via software, allow any digital input signal to be fed into the sound system regardless of sample rate and clock settings. Thus, even without separate synchronisation lines, any digital devices may be connected effortlessly.
Sound system with a +
The “+” version includes an extension that adds a word clock input and output and 2 MIDI inputs and outputs to the sound system. This expansion card is connected to the sound card via a ribbon cable and can therefore be freely positioned in one of the slots of the computer housing.
Expansion options
If several Clara D are installed in one computer, they are synchronised via the TDM SyncBus and appear as a combined sound system to an ASIO application. In the Beast Mixer, up to 32 audio signals can be exchanged with other Clara sound systems and thus also be integrated for the use with ASIO.
Fast and Reliable Multi-Client Treiber Suite
The continuously enhanced driver includes multi-client support for ASIO 2.2 as well as multichannel WDM audio / WASAPI with the lowest latencies in all software environments. This ensures that multiple audio applications can access the sound system simultaneously via the same or different driver interfaces.
Realtime Routing, Mixing and EQ
Each input signal of the sound system can be adjusted in volume and routed latency-free to any output. The BEAST DSP mixer also sums up to 64 signals to 8 different busses and plays them back on any number of outputs without delay. Furthermore, the BEAST Mixer adds playback signals from any DAW. All mix sums can be fed back to an application for recording. In each channel of the BEAST mixer there are 4 parametric EQ available for sonic processing.

Great product!
Style: 30 sqft
I can say this product makes a huge difference with road noise and is cleaner and easy to work with when applying compared to other mats that cost about the same price.

Very heavy and thick
Style: 30 sqft
I purchased mini brands of sound ending and this is by far the heaviest sound deadening I've ever ordered. I'm not installed yet but I have a good feeling that is going to work exceptionally in blocking sound. If weight is a concern for you I would recommend a lighter product however if sound quality and a quiet ride is your priority this is the one for you.

Siless Hybrid 3-in-1 - Far Exceeded my Expectations!!!
Model: SLH20025
I recently installed the Siless Hybrid 3-in-1 sound deadening mat in my vehicle, and I’m genuinely impressed. For just $80 for 25 square feet, this product delivers performance that rivals materials costing twice as much — and with far less hassle. If you're on the fence......Just buy it! You will not be disappointed.
Easy to Install: Unlike traditional sound deadening products that are stiff, sharp, and temperature-sensitive, this mat is soft, flexible, and easy to work with. I cut it cleanly with regular scissors and pressed it into tight spaces using just my fingers, so if in you don't have a roller or install tool, a good pair of scissors and your hands can get the job done. With other brands like Dynamat, the aluminum layer often leaves micro cuts on your hands and tears up your fingertips, but Siless does not due the acoustic layer being on top and above the aluminum layer that holds the butyl layer. So, it's very easy on your hands.
Even in cooler temperatures (around 50°F), I had no trouble applying it but it goes on better heated. If warm outside, I would leave the entire box out in the sun for at least 30 minutes when it's warm or heats it's very pliable and easy to mold. Make sure its where you want it because once applied it's not ever falling off. and it became even more pliable and easy to mold. No heat gun, no mess — just straightforward application.
I installed 40–50 square feet throughout the interior, covering everything except the headliner and the flooring forward of the rear seat. The difference in cabin noise is astonishing. I can turn my radio up concert loud with gut-punching bass, and from outside the car, it sounds like a factory sound system at mid volume. I was blown away by how well it contains sound — both inside out and outside in.
My exhaust is pretty aggressive and now is barely audible from inside the cabin. While driving, it almost sounds like a stock factory setup. The Siless matting actually changed the driving experience and feels refined.
If you're skeptical about sound deadening gimmicks, I get it, but this is the first product I've used and when I needed more, I went Stright to the 3 in 1 Hybrid matting and purchased it again. I love researching before buying and that's very uncommon for me to do.
Note: Proper installation is key, and it does take time and patience. But if installed correctly and in the right places, it works better previously used from paint-on sound deadening to Dynamat.
Update Nov, 2025
After using it this in 4 separate vehicles now. I feel the Siless’s 3 in 1 Hybrid has nailed it for best budget deadener that is better than dynamat extreme in performance and installation
Protip: buy a roll of 2-3” aluminum tape and tape the seams. After trimming the edges tend to very sticky between the panels. I ran a strip of aluminum tape over the seems to create a better seal and true moisture
I used it on four vehicles now and have I have not been paid to review and purchased every order myself.
3 in 1 Hybrid deadener by Siless is the best all around easy to apply sound deadner period!

Top quality
Model: SLH20025
This Siless Hybrid 3-in-1 sound deadening mat is easy to work with and feels high-quality. The butyl material is thick and pliable, making it simple to cut and fit into doors, floors, or panels.
After installation, road noise and vibrations are noticeably reduced, and it also seems to improve the overall cabin feel. No bad smell.
At 25 sq ft per roll, it’s a good value for anyone looking to dampen noise and improve car acoustics. Overall, a solid, effective option for automotive soundproofing. Used on a Fiesta ST.

Made a big improvement in cabin noise—highly recommend
Model: SLH20025
Siless Hybrid made a huge difference in reducing noise in the floor of my truck cabin. In some areas, there was basically just bare sheet metal between the inside and outside, so adding this really helped the truck feel more solid and noticeably quieter on the road.
I used Kilmat on the doors, and honestly I wish I had used Siless Hybrid there too, but it was too late by the time I realized the difference. This material is very sticky, easy to cut, and simple to apply, which made the install pretty smooth.
Just a heads-up: the tacky side gets messy and will bond to clothing really easily, so be careful during installation. Overall, I’d definitely buy it again—great product with real results.
