 Protection :

      -> AD-8300 is protected against excessive operating temperature, shorted speaker       connections, ground faults, and other common fault conditions.

      -> The Amplifier has over heat protection, DC protection, short circuit protection, over load protection

      -> For the high frequency transformer used on power supply: It has overheat protection, overload protection, short protection, over voltage protection and under voltage protection

     -> Fan: The speed of the fan is determined by the temperature within the unit. At lower temperature the fan will be off, When the temperature increases the fan will auto detect and increase the speed to control the temperature of the unit

    TW AD-8300

    This is a very detailed and clear sounding amp. Aamir was one of the best to deal with. I heard sounds from this amp that i never heard from my AVR. I would buy from summit HI-FI again 0ne of these best to deal with.

    Amazing amplifier

    Amazing amplifier for the money! Best deal on the market. Very detailedand and dynamic. I bought this to power my 7.2.4 home theater, and have it paired with the Tonewinner AT-300 processor(which I've owned for a year) They sound great together, instantly I noticed an improvement over the previous amplifiers I was using. The banana plugs are nicer in person then the pics online and the brushed aluminum matches the tonweinner AT-300 beautifully. highly recommended!

    TW SD-8300 -11

    I had the 5 channel amp.before & needed to expand .It has excellent depth & sound for my cinema maison and musical with clear sounds of the instruments but also has a good punch for action movies in which I also have the SVS center & the Sb 16-Ultra. So it's an excellent kit to enjoy my movies & sports at home!


    I've had the 11 channel amp for a few weeks now and have been impressed with its performance. Sound quality is top notch, I am not an audiophile expert but I like what I am hearing, very clean, distinct and powerful experience when watching atmos movies.
