Features like 1.3- ohm load capability that makes it possible to drive multiple subwoofers with one amp, more models with speaker level inputs, higher maximum power, and even better sound quality. Naturally, the power amplifiers play an important role in our three- system strategy. Amps are of course vital elements of the Play Loud systems, and the top- end models should also be integrated into the Mobile Media systems. Copper bars instead of wires increase power capabilities. They have to be straight, which complicates the circuit layout, but Alpine has succeeded in using them.
Large transformers ensure high power efficiency and low current leakage.
Primary choke coil is a dual parallel type to reduce power losses. STAR Circuitry design lowers distortion. It has been further improved in the MRV- T707, achieving circuit patterns that allow a larger flow of current. Compatibility Low output loads increase the output current in comparison with normal 4- ohm loads. This leads to more output loss that is likely to cause the amp to shut down due to over- current and overheating.
