Constant pressure amplifier KNMK-360
The Constant pressure amplifier uses deep negative feedback so the output voltage is very stable, and the received load within its rated power range has little effect on the output voltage of the amplifier.
1. 5-way signal input (front panel one-way microphone input, rear panel two-way microphone input, two-way line input)
2. With 100V, 70V constant voltage output and 4~16 Ω constant resistance output;
3. The volume of each input channel is adjusted independently;
4. Independent adjustment of treble and bass;
5. Mic1 automatic silent tone;
6. Led level display;
7. It has perfect output short-circuit protection and over temperature protection functions;
8. Forced start of cooling fan;
9. It is very suitable for medium and small public places;

Note: only one pair of the four output terminals of the power amplifier should be used.
Silent sound function
Mic1 has the highest priority, and the signal input from this socket will suppress the input signals from other sockets.
1 .do not block the vent of the equipment.2. Before use, pay attention to check that the power cord is not damaged 3. The power plug and socket should match. If the socket and plug do not match, a suitable power socket must be connected. People are not allowed To destroy the power plug. 4. The power supply used by the equipment should have sufficient capacity and independent and reliable grounding wire. 5. When using this machine, pay attention to good ventilation, prevent dust and humidity, and avoid direct sunlight and strong vibration. The most suitable working environment 5-28 Centigrade, relative humidity <99%, if working for a long time, when the ambient temperature is too high, it is recommended to take effective cooling measures. 6. The required power supply voltage of this machine is 220v+10%50/60hz. If the power supply voltage is too high or too low, it should be switched off immediately Check it and power it up again after troubleshooting 7 when the power is turned on and the signal is input, if you hear a short alarm signal tone, it indicates that the load is short circuited, you should immediately cut off the power and add To check. Power up again after troubleshooting 8. Before starting the power amplifier, be sure to turn the volume to the minimum and turn it up slowly after starting the power amplifier to prevent damage to the loudspeaker. When shutting down, please Turn the volume to the minimum, and then turn off the power supply to reduce the total impact on the power grid
