Audison SR 4.300 4-channel amplifier with crossover and great power packed into ultra-compact dimensions (85 W x 4 4?)
SR line, perfected by taking full advantage of the capabilities of the latest amplification devices. After numerous listening tests with professionals and enthusiasts, Audison's R&D team decided to adopt a new class D technology called ADT (Audison D-Class Technology) for this line of amplifiers, which has made it possible to considerably reduce their size, totally preserving the audio performance that characterises every Audison design.
As far as the electronic design is concerned, every aesthetic and functional detail of the Audison SR 4.300 has been taken care of, resulting in a compact amplifier made of extruded aluminium with rounded corners, which facilitates the installation of the product in narrow spaces. Thanks to the generous heat sinks on the two short sides of the amplifiers, there is no need for internal cooling fans, which often cause noise and dust accumulation.
In keeping with tradition, the SR amplifiers confirm their vocation for versatility by including on all models a complete filter section, suitable for any kind of audio system configuration. The controls, protected by a satin-finished aluminium panel, are located on the top panel of the amplifier, so that they can be easily reached from above, even after the product has been installed. When the system includes an Audison bit processor, the filter section can be totally excluded.
Audison USS
Thanks to the integration of Audison USS (Universal Speakers Simulator) technology in the high level inputs, the SR amplifiers can also be conveniently connected to OEM sources equipped with the 'speaker load detection' function, which monitors the presence of a low impedance load enabling the audio outputs.
Audison SR 4.300 allows multiple connectivity
All models have balanced high-level inputs for connecting to the OEM headunit speaker output and a low-level RCA for after-market speakers. When using the high-level input, the ART (Automatic Remote On/Off) function can be enabled to control the amplifiers' power-up with the headunit's power button. In addition, there is a remote IN / OUT socket to allow control of multiple amplifiers in cascade that turn on when needed.
Through the PRE-OUT signal using the Speaker-IN socket it is possible to interface the amplifier with OEM sources that only have amplified outputs, allowing for system expansion.

Very sturdy
Style: 10 Inch, Size: 172 Count (Pack of 1)
When we go camping, we use these Dixie plates a lot. They’re very sturdy and the cleanup is easy Peezy. The design is bright and cheerful are easy to use. It’s the great size for dinner plates and they also have smaller size plates as well as bowls. They’re very durable and we’ll hold up on heavy foods. We always keep a good supply on hand because when you’re on vacation, you don’t want to wash the dishes. They are great you’re using them and you throw them away or you can burn them.

Strong, Reliable Plates for Everyday Use
Style: 10 Inch, Size: 100 Count
These Dixie Ultra paper plates are a great upgrade from regular disposable plates. They’re strong and sturdy, so they don’t bend or leak even with heavier or saucy foods. Perfect for everyday meals, cookouts, or quick cleanups when you don’t feel like doing dishes. The 10-inch size is just right for full meals, and the pack lasts a good while. I’ve used them for hot foods without any issues—they hold up really well. Overall, dependable quality and worth paying a little extra compared to cheaper, flimsy options.

Best Plates Ive ever known!
Style: 10 Inch, Size: 172 Count (Pack of 1), Style: 10 Inch, Size: 172 Count (Pack of 1)
If you’re tired of the "double-plate shimmy" where you have to stack two flimsy plates just to survive a barbecue, the Dixie Ultra 10-Inch Plates are a total game-changer. This 172-count bulk pack is the gold standard for anyone who actually likes to pile on the food.
Why They’re Worth It:
True Strength: The "3X Stronger" claim isn't just marketing fluff. These can handle a massive helping of steak, potato salad, and corn on the cob without folding under pressure.
Soak-Proof Shield: They feature a high-quality coating that keeps grease and sauces from leaking through to your lap or your table.
Microwave Safe: Unlike some cheaper alternatives, these don't get soggy or "wilt" when you're reheating leftovers.
Value Size: Getting 172 plates (divided into 4 convenient packs) means you're set for multiple parties, holidays, or just those nights when you really don't want to do the dishes.
Bottom Line: These are the "heavy lifters" of the paper plate world. They’re large enough for a full dinner and tough enough to handle the messiest meals. Highly recommended for anyone who values durability over price-point flimsy alternatives.
