U 6 mic/line input and 3 road music source input u 100 V, the phone and call station input (VOX) take priority and u 2 area and broadcast only output voice activation emergency control button u 120 u and 240 W high power output of these spots li mixing amplifier are high-performance professional public broadcasting equipment, have modern advanced performance. They are simple and easy to use, simply by placing the device where it needs to be, and by using its own functions, they can be put into use, keeping users away from the complicated work. The ability to play clear broadcasts or music is as easy as turning on the receiver. In addition, amplifiers are affordable and do not require the sacrifice of features such as press in, priority, and flexibility. Basic function microphone and line input all microphone/line inputs can be switched between microphone level and line level sensitivity. The input can be either an equilibrium signal or an unbalanced signal. The user can turn on the phantom power to power the capacitive microphone. The priority of input channels 1 and 2 can be higher than that of all other microphones and music input channels: • input 1 can be activated by closing contacts on PTT (press or speak). The amplifier can be configured to play the 2 tone prompt before broadcasting. · input 2 can be automatically turned on when the signal is transmitted to the input, such as when someone is speaking into a microphone (VOX is activated). When a high priority is assigned to one or both inputs, the attenuation value of lotus pluggable input can be set between the ‑2 dB (low attenuation) or -infinity dB (mute). This will provide dialogue or voice-over. In addition, input channels 1 and 2 are also equipped with optional voice filters to improve broadcast clarity. Music input independent music input has its own input selector and volume control. Users can choose music sources such as CD players or radios (such as pln-dvdt) or set music volume levels. The user can adjust the sound effect of music source independently from microphone/line input. So when music needs a better low frequency performance, the sound of the microphone is still very clear, which is truly unique among products of the same class. Personalized Settings this amplifier offers a number of unique features, such as desirable tags on which users can write input, music source, and partition names. These tabs can then be mounted on the front panel and protected by a transparent window. Another very useful feature is to specify preference Settings on the front panel by inserting colored needles at the preset levels of all the knobs. You can then indicate that the user sets all controls at a silver pin so that the system performs a specific purpose. Another user can set all controls to the red pin according to their configuration. Tone control unique tone control can provide mic/line input and music with separate control, so the user can be optimized microphone voice to excellence of speech or singing. Also, the tone control for background music can provide a perfect music reproduction. In addition, these tone controls are not regular bass and treble controls. Experience tells us that the ideal tone controls should be a can not only control the bass, can also be used to control the high on the basis of traditional tone controls, at the same time can effectively adjust the frequency response curve, so as to perfect solve various problem encountered in real life. Tone controls for microphone and line inputs can increase the warmth of the language without adding low-frequency noise, and also remove the rumble without affecting the warmth of the low frequency. At high frequencies, tone controls can increase brightness without producing sharp sounds. If attenuation is required, it reduces the sharpness and sharpness of the sound and does not affect the sharpness of the sound
