DSA4000 Cinema Power Amplifiers
Features:
.Complementary feedback geminate transistor type "output" circuit, combined with large radiator and variable speed fan, has strengthened the cooling capacity of high power pipe and improved reliability of the output.
.It is designed with multiple circuit protection systems, including the DC output protection, the output short-circuit protection, the On/Off impulse protection and temperature protection system.
.The XLR interface is used for the input; the terminals are used for the output.
DSA series cinema power amplifiers, includingDSA1000, DSA2000, DSA4000, DSA6000, DSA8000 five varieties, are specially designed for the developing small and medium-sized cinemas. They are assembled with the highest chosen quality components. After strict aging test, it is guaranteed that every equipment shows high performance criteria and reliability.
DSA6000 amplifier has two different sizes of power outputs, DSA8000 amplifier has three different sizes of power outputs, they are respectively designed for two-way and three-way frequency main speaker systems with electronic frequency dividing networks.
