SKU TW AD-7300PA+ Power Amplifier(New) Categories , Tag
AD-7300PA is one 7 channels amplifier that specially designed to use with the AV preamp AD-7200HD. It is one high end amplifier with switching power supply design, it can be applied as both home theater and HiFi. Its sound quality is extremely outstanding. Power output 7x300W (8ohms) .
MAIN FEATURES 

  • 7 independent amplifier circuit modules, which are low distortion and high speed Hi-Fi,can offer full audio resolition.
  • note: FL, FR channels use external heatsink,their class A working current is higher that other channels.Before working,make sure the cable are correctly connected.
  • Perfect amplifier proctecting circuits (short proctection, self-excitation protection,overheating protection and DC protection.
  • 7channels equal power output, meet different occasion needs.
  • Big power switching power supply, abundant power stock.
  • Big power tube parallel output, can supply 45A current output ,big output power margin.
  • High strength and durable casing structure,scientific inner setting, strong anti-interference ability ,high quality aluminum panel,simple and easy apearance.
The five-fold protection of overvoltage ,overheating, overload, overcurrent and short circuit is adopted to ensure the normal use of the machine and speaker.
AUDIOPHILE OUTPUT INTERFACEThe input of the circuit uses selectable balanced and unbalanced inputs,a low-noise dual differential amplifier circuit and a mirrored cross-current source load. This can improve the signal-to-noise ratio of the whole machine, making it more suitable fir home theaters,strong driving force ,high conversion rate ,etc, the circuit final stage design temperature compensation circuit and DC servo circuit, and design a negative feedback circuit to ensure the stability of the machine.

HI-FI CIRCUIT DESIGN
The hi-fi circuit structure of the independent 7-channel modular discrete element power amplifier unit circuit board is completely used. The hi-fi circuit and technology,loyout and materials used for each channel are almost the same .Among them ,the front channel .left and right chnnels are exposed radiators,which not only becomes larger,but also the static currents at all levels of the circuit also increase the current of the power amplifier stage. Seven huge heavy-duty cast aluminum comb radiators ensure the technical basis for 7-channel and other power outputs. 
Weight 26.7 kg
Dimensions 57 × 57 × 32 cm
