Active subwoofer amplifier - is a major part of the active subwoofer speaker, which is used to push passive subwoofer speakers.
Upgraded version: added phase adjustment, automatic standby, and 8-tube linkage
Rated output power 1000W8 ohms (directly connected to the speaker)
Features: 1. It has been debugged and installed, and when powered on, the speaker can be connected. (It is recommended to push around 8-18 inch 500W speakers) (equipped with exquisite craftsmanship)
2. Adjustable frequency point (40-180), volume adjustment,
3. Full relay protection: startup delay, DC output, horn short circuit, etc
4. Advantages of having a DC optimization system: providing continuous offset voltage zeroing control for the amplifier, controlling the DC output potential of the amplifier, expanding the low-frequency response of the amplifier, and reducing phase distortion of low-frequency signals.
5. The circuit board adopts original disassembled tubes, with a reasonable design and layout, and a very high signal-to-noise ratio (no noise can be heard without inserting the sound source input line).
