PAI integrated amplifier series features:1) The protection to circuit starts when the temperature is too high, the input signal is too big or overloaded. The radiator-fan goes faster while it is alarming by sound and light.2) User can force it to switch to the priority for signal input and carry out emergent broadcast by short circuit or DC24V forcing switching.3) Providing CD, AUX, TEL and 2-channel MIC input as well as general volume control, alt and bass tone adjusting and level output indicating.4) Providing 5-way sub-area channel and carrying out sub-area and complete zone control by 5 sub-area buttons and 1 complete zone button.5) When the AC power source is in a fault, the equipment can go on working by the back-up power supply system.PAI-B integrated amplifier series features:1) Protect the circuit when higher temperature, larger input signal or overload. The radiator-fan moves faster when it alarms by sound and light.2) Balanced input expands signal transmission distance and improves its anti-jamming ability.3) CD, AUX, TEL and 2-line MIC input provided, users are able to adjust the volume of each channel between 0~32 grades by the touch screen.4) Input priority control available. When the user input MIC1, TEL, matched partial tone or siren, the equipment will carry out mute control over MIC2, CD, AUX through mute level set by the user in order to interpose emergency broadcast.5) 5-channel sub-area are provided. Sub-area control and the compete zone control are respectively carried out by 5 zones option keys and 1 complete zone option key.6) When AC is in a fault, the equipment will be made to go on running by backup power supplying system.MPA integrated amplifier series features:1) 70V and 100V stable power output port and 4~16ohm stable resistance output ports are provided.2) Separate volume control over each channel and bass and alt adjusting are available.3) Short circuit output protection is provided.4) MIC1 priority compared with other input channels.5) Pre-signal of MPA can be connected with other amps by PRE OUT port while other pre-amps can also be connected with it by AMP IN port.6) Naturally dissipating heat to decrease the working noise of the equipment7) Matched with bracket for rack.8) When AC is in a fault, the equipment will be made to go on running by backup power supplying system.
