SUB1500W high-power heavy bass amplifier board SW18-inch bass pure active heavy subwoofer bass 8 major tubes

sort by color

2 large capacitors

4 large capacitors

This amplifier only has bass output and does not have full frequency output

Active bass amplifier - is the main part of the active subwoofer speaker, which is the amplifier used to promote passive subwoofer speakers.

Upgraded version: Added phase adjustment..4 imported super large filter capacitors.8 tube push

Peak output power 1500W8ohms,

The actual power is 1000W (it can be used directly by connecting the speaker)

Features: 1. It has been debugged and installed, and you can get excited by powering on and connecting the speaker (it is recommended to push 8-18-inch 500W speakers) (equipped) exquisite craftsmanship

2. Adjustable frequency point (40-180), volume adjustment,

3. Full relay protection: power-on delay, DC output, speaker short circuit, etc.

4. Advantages of the DC optimization system: Provide continuous offset voltage reset control for the amplifier, control the DC output potential of the amplifier, expand the low-frequency response of the amplifier, and reduce the phase distortion of the low-frequency signal.

5. The circuit board is made of original imported tubes, with a reasonable design and layout, and the signal-to-noise ratio is high (no noise can be heard without plugging the audio source input line).
