SP2400 Digital Amplifier
SP2400 Digital Amplifier
Introductions
This series of digital amplifiers can provide up to 1200W output power per channel. In applications requiring high power and long - term reliability, no other amplifier can compete with SP2400. This series of amplifiers can greatly reduce the thermal output and equipment weight without sacrificing the output power, and can be used in a large number of acoustic amplification. Such as opera house, movie theater, church, conference center, theme park and so on.
Class D power amplifier has super high efficiency, which can reduce the heat dissipation consumption while providing higher power for the speaker. The typical operating power of the output stage is 95%, and only 5% of the input energy is consumed as heat.The technology makes it possible to build power amplifiers that are smaller, lighter and consume less power.The maximum efficiency of the traditional power amplifier can be achieved only when it is output at the maximum rated power.But class D amplifiers’ efficiency and output level is not highly relevant. The average power density of music is 40% of its peak value.This means that at the same SPL, other amplifiers (non-class D amplifiers) can produce 10 times as much heat.
This series of amplifier can bring clear high frequency and compact, pure low frequency.Is the most accurate reproduction of audio signal in the application can ensure ultra-low total harmonic distortion, optimized frequency response, high power bandwidth and damping factors.
Features
▼Overload protection - this series of amplifiers has an output current protection function: when the output current of the amplifier channel exceeds its specified peak current output, the current will be limited to the specified working range by the protector. If the output current of the amplifier channel exceeds its specified peak current output, for example, the output circuit is short.In this case, the amplifier will be disabled (mute) for 1000ms and will automatically restart after the short-circuit state has disappeared.
▼Over-voltage/under-voltage protection - when the working voltage exceeds the upper limit of the maximum allowable working voltage or is lower than the lower limit of the minimum allowable working voltage, the power supply starts the protection mode and turns off the power supply.
Note: working over 240 VAC voltage for a long time may cause power damage
Power control - the series of power amplifiers support power output control; By setting the power scale of the panel, the matched audio can work completely reliably within the range of power requirements.
▼Temperature protection; a perfect temperature protection sampling, while monitoring the amplifier radiator and power supply temperature; When the working temperature of radiator exceeds the limit value, the output power will be limited. When the operating temperature of the power supply exceeds the limit value, the output will be turned off. When the temperature returns to the limit value, the power supply will be restarted automatically.
Application
Government and enterprise meetings, small and medium-sized conference rooms, lecture halls, small and medium-sized banquet halls, VIP reception halls, conference centers, teleconference, churches, theme parks and other places where sound reinforcement is applied.
