Broadcast amplifiers are different from other amplifiers. Its main feature is its 70V and 100W constant voltage output terminals. This is because broadcast lines are usually quite long and must be transmitted with high voltage to reduce line losses.
The most important indicator of a broadcast amplifier is the rated output power. How much rated output power should be used, depending on the total power of the broadcast speakers. For the broadcast system, as long as the total power of the broadcast speaker is less than or equal to the rated power of the power amplifier, and the voltage parameters are the same, it can be arbitrarily matched, but considering the line loss, aging and other factors, the power margin should be left as appropriate. According to the requirements of the 'Specifications', the capacity of the power amplifier equipment (equivalent to the rated output power) should generally be calculated as follows:
P=K1. K2. Σ P0 (2)
P-amplifier output total electric power (W)
P0 - maximum power per broadcast at the same time (equivalent to partition)
P0=Ki. Pi
Pi-i-zone speaker rated capacity Ki-i-th partition requires coefficient at the same time:
Service broadcast room program, take 0.2 ~ 0.4
Background music system, take 0.5~0.6
Business broadcast, take 0.7~0.8
Fire accident broadcast, take 1.0
K1-line attenuation compensation coefficient: 1.26~1.58
K2-aging coefficient: 1.2~1.4
Accordingly, if it is a background music system, the rated output power of the broadcast power amplifier should be about 1.3 times the total power of the broadcast speaker.
N+1~~N-1 emergency broadcast system. According to the 'norm' requirements, the rated output power of the emergency broadcast power amplifier should be 1.5 times the sum of the field sounder capacities of the three partitions with the largest broadcast speaker capacity. There are many types and models of broadcast amplifiers . Which one to choose depends on the specific structure and investment of the broadcast system.
