The answer is yes, but it is not necessarily appropriate. Instead of smart radio amplifier professional amplifier, you need to think of ways to enhance (or specification) and its output voltage. Way: l with appropriately rated output power professional amplifier or power amplifier combination (bridged or concatenation), constant voltage output compatible with smart radio speaker (usually 100V). l in professional amplifier output end is connected with a suitable output transformer. Professional power amplifier output voltage Uo with its rated output power (Po) and the rated load resistance (Rz): Uo = (Po? Rz) 1/2 Accordingly, the 2500W / 4Ω's, professional amplifier exactly 100 V The output voltage can be used directly. But smart radio speaker total power can not exceed 2500 W (only consider the the amplifier load capacity, did not consider the requirements of the point of order); On the other hand, no matter how small total power of intelligent radio speaker, also can not use the power of professional power amplifier and intelligent broadcast line should not be guaranteed transmission voltage. Bridge with two 650W / 4Ω professional amplifier can also get close to the 100 V output voltage. Obviously, when the smart radio speaker far less than the total power of 2500 W, the two approaches are very uneconomical. If you want to use the intelligent radio speaker considerable power amplifier should be above formula calculate its output voltage, and then connected with the appropriate output transformers. However, professional amplifier to drive the the smart radio speaker then professional amplifier with output transformer can easily lead to damage to power amplifier, you need to take appropriate measures (omitted here). Professional speaker can be as smart radio speaker, but to be connected with the line between the transformer. As mentioned earlier, the line between the transformer impedance transformation from the role of professional speaker can draw quite the same rated power broadcast transmission line in "constant pressure" smart "fixed resistance". Without "line between the transformer and the appropriate professional speaker series and parallel, and can also be used, but to go through the tedious calculations; during operation, as long as one of the speakers damaged, the system is likely to subvert (all ring or burned down other speakers or burned to power amplifier). To act as intelligent broadcast mixer preamplifier is barely feasible. Mixer is usually no signal prioritization, intelligent broadcasting system must forcibly insert "function is not easy to achieve. In turn, intelligent radio amplifier and intelligent radio speaker can also be used for professional audio systems. But because they have a built-in output transformer or line transformer, its frequency response characteristics are nowhere near as good as the grade professional equipment. Intelligent broadcast pre-amplifier for professional audio systems also are forced, because it does not have features such as grouping, balancing effect; prioritization features for professional audio systems, the most redundant. So interchangeable Public Intelligent broadcasting system and professional sound system equipment fall feasible, but it is not necessarily appropriate. Usually result in cost performance deterioration. Jiaming Yang 1503 +71780 +75 www.69139139.com 534 +64 +9528 Milan sun, Zheng * City Market Building 5, Unit 2, 208
