time2024/09/30
- Sinbosen FP series professional stage power amplifier rear panel function introduction.
The FP series amplifier from Sinbosen is a high-performance switch-mode power amplifier designed specifically for large concerts, tours, theaters, and other professional settings. It offers exceptional stability and high-fidelity sound quality, making it suitable not only for professional use but also for high-end home audio systems. As we all know, in addition to the three main components of the amplifier, namely the internal amplifier board, power board, and channel board, there are many other small parts. Externally, the amplifier mainly features a front panel and a rear panel.
The front panel is a part that everyone is more familiar with, and its main functions include:
Level adjustment: The front panel potentiometer is used to adjust the level of the input signal, ranging from negative infinity to 0dB.
Power indicator light: Indicates whether the amplifier has been powered on.
Protection indicator light: It lights up when there is an abnormality inside the amplifier, such as overheating or a short circuit.
Signal indicator light: It blinks when an audio signal is passing through.
The back panel is more complex, with functions such as bridge connection for the amplifier, voltage, and power. Many customers do not know how to set up the bridge connection function of the amplifier and are not very familiar with the small switches on the back panel. Below, we will introduce the functions of the back panel.
(1) the first part: 1.2.3 dial for the gain adjustment, +23 dB to 44dB, each step is 3dB.Up and down the position gaincorresponding to the code on the map,
(2) the second part: 4. 5 dial for the bridge or signal parallel (mono) mode, when setting the bridge mode, the four-core speakerplug. Then 1 +, 2-endt When the signal parallel mode is set, the signal can be input to the A and C channels, and 6dB gaincompensation is required
(3) The third part is the 8-bit DlIP switch, dialed 1.2.3 or 5.6.7 for the corresponding per channel power compression adjustmentoutput 54V ~195V, the corresponding number .The value is shown in the figure
(4)The fourth part is 8-bit dial 4 and 8, is the corresponding MODEmode, the corresponding channel to push the subwooferrecommended when the use of high frequency is not recommended Use(SOFT: release compression limit <push bass state>.HARD for compression limit protection <push full or medium frequency speakers>
