4-way microphone / line input and 3-way music source input

 u 100 V and telephone input with priority and vox u broadcast only output, 3-wire volume coverage u voice activation emergency coverage u wide power selection range (30, 60 and 120 watts) these variegated hybrid amplifiers are high-performance professional public address equipment with modern advanced functions. They are simple and easy to use. They can be put into use just by placing them in the required position, eliminating the trouble of users. Be able to play clear radio or music, just like turning on the radio. In addition, the amplifier is very affordable and does not need to sacrifice functions such as ducking, priority and flexibility. Basic function microphone and line input all mic / line inputs can be switched between microphone level and line level sensitivity. The input can be either a balanced signal or an unbalanced signal. The user can turn on the phantom power to power the condenser microphone. Input channels 1 and 2 can take precedence over all other microphone and music inputs: · input 1 can be activated by a contact closure on the PTT (i.e., press to talk). 2 tone tone tone can be configured to play before broadcast. · input 2 can be turned on automatically when the signal is transmitted to the input, e.g. when someone is speaking into the microphone (VOX active). When one or two inputs are assigned higher priority, the attenuation value of lotus plug input can be set between ￣ 2 dB (smaller attenuation) or - ∞ dB (silence). This will provide dialogue or voice over. In addition, input channels 1 and 2 are equipped with optional voice filters to improve the clarity of broadcasting. Music input independent music input has its own input selector and volume control. Users can choose music sources such as CD player or radio (e.g. pin-dvdt), and set the music volume level. Personalize this amplifier offers a number of unique features, such as removable tags on which users can write down input, music source, and partition names. After that, the labels can be mounted on the front panel and protected by a transparent window. Another very practical function is to indicate the preferred setting on the front panel by inserting color pins at the preset levels of all knobs. You can then instruct the user to set all controls at the silver needle to enable the system to perform a specific purpose. Another user can set all the controls in the red color needle according to his own configuration. The integrated amplifier provides telephone / 100 V emergency input (with vox activation) and is designed to easily integrate with another broadcast system or telephone paging system. This input has its own preset volume control and takes precedence over all other inputs, including the call station and input 1 and input 2. In addition, the device is equipped with a line output for adding amplifiers to large systems requiring higher output power. For example, this output can be switched to music only mode to provide a wait for music function for the phone system. The power hybrid amplifier has three output power options of 30, 60 and 120 watts. The 100 V constant voltage connection line and the 4 ohm low impedance connection line can provide this power directly. In addition, these amplifiers also have a separate 100 V "call only" output channel for broadcast areas where only priority broadcasting is required. Call only output can also be used for 3-wire remote volume coverage. The output status LED Vu table is used to monitor the main output. The headphone jack under the VU meter provides mixed output function. In order to ensure the overall reliability and ease of use, a limiter is integrated in the output stage, which can limit the output when the signal level used by users is too high.
