1000W Digital power amplifier WITH switching power supply

1. The power supply voltage AC220V input(default）/AC110V input

(AC100-120V, AC110V, CP3 CP4 are connected together, 60Hz

AC200-240V,AC220V, CP3 CP4 open)，50Hz

2. Speaker load: 4-8Ω

3.RMS power: 500W/ 4 Ohm， 300W / 8 Ohm

4. Peak power: 1000W / 4 Ohm

5. Channel: Mono

6. Frequency response: 20HZ--20KHZ

7.Pre-voltage output +15v, 0V,-15V

8.Fan voltage output +24V

9.Distortion: THD≤1%

10.Input sensitivity: 1.5V

11.Magnification: 30 times

12.Boot delay, anti-impact sound: 1-3 seconds

13.Speaker output short circuit protection: yes

14. Size: 200X130X42mm

Note:

Due to the high power of the power amplifier board, a fan (DC24V fan) must be installed for long-term high-power operation. The power is large and the heat is also large.

Features:

1. The power is very large, and the fan needs to be added with heat. From the right digital amplifier section to the left side of the switching power supply section.

2. Temperature protection: The temperature of the radiator rises to 85 °C, the protection starts automatically, and the amplifier stops working. After the temperature of the heat sink drops, the power amplifier automatically starts to work.

3. Overload protection: The load is overweight and will protect!

4. Speaker protection: The output has DC, the relay is disconnected, and the speaker is protected! .

5. Anti-shock: There is NTC thermistor at boot to prevent inrush current!

6. The start relay is delayed.

Note:

1.AC N and AC L power supply input AC 210-230V.Do not exceed the supply voltage range.

2.AC N and AC L power supply input alternating current, it can be changed to 110V power supply and cannot be used again with 220V power supply.

3. The working state of AC100-115V is that any pin of CP3 is connected to any pin of CP4.

4.AC200-240V CP3,CP4 OPEN

5.P1 two-core row seat +24v G DC output, connected to a 24v fan.Pay attention to the polarity of the fan and do not reverse it.The fan interface cannot be shorted, otherwise it will cause failure and not work!

6.The high power of the power amplifier requires heat dissipation, and the no-load also requires heat dissipation. In addition to the heat sink, there are many other heating components. These components also require fans to blow, such as transformers, output inductors, large resistors, large capacitors, and ballast bridge stacks. These are relatively large heat and require a fan to blow them.It is recommended that the fan blow air from the power amplifier part to the power supply part.

7.The output interface has four ports. The two terminals are connected in parallel. It can be connected to any one terminal. It is used to connect the speaker, SPK-SPK+ load output, and connect the 4 ohm-8 ohm speaker. You cannot connect the speaker with a load of less than 4 ohm. Remember, the load is too small, it is easy to protect the speaker!

8.The auxiliary power supply of the P2 row seat outputs +/-15v to the pre-stage and the current is only 500MA. It cannot be overloaded, nor can it be connected to the input voltage. It is only output to the pre-stage board. Remember.

9.The G in of the P2 row seat is the signal input. G means GND, which means ground wire. It also means the negative signal input. in means the positive signal input. Don't reverse the polarity. Remember.When the input signal is up to 1.5V, the output power reaches the maximum value, and it cannot exceed the input 1.5V much to avoid excessive overload and damage to the power amplifier.

10.It is best to use a shielded wire for the input signal line to avoid interference.The input signal cannot only be connected to the signal input, but not to the signal ground. Remember to avoid damage caused by self-excitation.(Do not hot-plug the signal input), it is not recommended to take the mobile phone signal.

11.The AC power supply is high-voltage, and it cannot be tied together with the bass wire. The AC input is high-voltage, and it cannot be tied together with the signal input, the auxiliary power supply +/-15 output, and the speaker output line.

12.Do not tie the signal input with the speaker cable.So as not to cause high-frequency self-excitation to damage the power amplifier.

13.The switching power supply is with high voltage, so remember to be careful not to touch the high voltage part with your hands.

14.D12 If the red light is on, it means that there is a short circuit in the power amplifier part.Maybe the fan is shorted, maybe the pre-stage power supply is shorted.Or the power amplifier is damaged.

15.If the temperature of the radiator exceeds 85 degrees, the power amplifier will automatically protect and stop working. After the temperature drops, it will automatically start.
