Tone chip: NE5532

DC chip: 2596

Full frequency frequency response: 20Hz-20kHz (±3dB)

Speaker matching impedance: 4-8Ω

Distortion: 0.03% when outputting 1W

Working voltage: DC24-48V, 5A or more

Signal to noise ratio: ≥106dB

Input sensitivity: 0.775V

Dimensions (L*W*H): 120*117.5*36MM (without protruding knob section)

Bass cutoff frequency adjustment range: 40-300Hz

Bass attenuation slope: -12dB Slope

SUB mode： the bass cutoff frequency can be changed by adjusting the SUB FREQ knob.

Note:

PBTL/SUB Switch:

When "PBTL/SUB" is switched to "SUB", SPK OUT connects to the passive subwoofer.

When "PBTL/SUB" is switched to "PBTL", SPK OUT connects to the full range speaker.

The SUBOUT is connected to active subwoofer.

At 32V 5A, speakers 4Ω 120W / 8Ω 80W

If the power of the speaker is too low, the power amplifier chip will be powered off for protection.

Common problem:

Q: All my lines are connected, but there is no sound output?

Answer: 1. Check if the POWER indicator is on. If it is not lit, press the POWER button to turn it on. After pressing the power button, the indicator light still does not light. At this time, you can find a laptop power supply to test to determine whether it is a machine fault or a power failure.

2. If the indicator light is on, check if the VOL knob is in the minimum state, such as clockwise rotation in the minimum state.

3. If both of the above are normal, check if the device that inputs the sound source is paused, muted, or the volume is at its minimum.

Q: Why is the sound broken?

A: When the power amplifier exceeds the normal output power, there will be a large distortion. At this time, you can adjust the volume of the front stage or the volume of the power amplifier to be normal.

Q: Why does the speaker have a large current sound?

A: If you are not using the original standard power supply, please replace the power supply before testing. A lot of power supply in the market has a large interference coefficient, which will cause a large current sound.

Q: Why do I not play the sound source after I plug in the input cable, will the speaker have a lot of noise

A: When using a signal line without shielding, there will be interference signals entering the amplifier. If you hate this sound, you are advised to replace the shielded signal line or unplug the signal line.

Q: Why doesn't my amp work after working for a while, and then work normally after disconnecting for a while

A: Usually this is the overheat protection of the amplifier. The output power may have exceeded the design power. At this point, you can lower the volume and try again.

Q: Why is the volume of the machine unchanged, and the sound source is different when accessing different audio sources (such as connecting the CD first and then changing to the mobile phone)

A: The output signal amplitude of different types of audio equipment is different. The mobile phone is usually 0.35mV, while the CD is 1V. The output signal amplitude of the source directly affects the size of the sound.

Q: Why is the power amplifier starting to listen to the sound is not very good, the high frequency is not clear, but the sound is normal after working for 8 hours?

A: Speakers and amplifiers are very sensitive devices. There will also be a familiar and matching process between each other. Usually, our new amplifiers and speakers will be down for more than 10 hours, and the sound will be very good.

Note:

1. Do not open the case privately. Improper handling may result in electric shock.

2. Please use the switching power supply of the regular manufacturer, otherwise the risk of damage to the machine will be damaged.

3. Do not place the machine in a high temperature and high humidity environment.

Package included:

1Pcs A3001 Amplifier

1Pcs Power Adpater (Optional)
