This post describes a six-channel amplifier board built around TDA2030 devices. The original listing provides the board photos and several specifications; treat the figures below as listing claims until you confirm them against the board markings and its manufacturer documentation.

Specifications shown in the listing

• Power input: listed as dual 12 V AC (12-0-12 V).
• Speaker impedance: listed as 4–8 Ω.
• Output rating: listed as 6 × 18 W; actual output depends on supply, load, cooling and measurement conditions.
• Input: RCA; the listing describes stereo-surround and six-channel input modes.
• Dimensions: listed as approximately 160 × 80 × 44 mm; confirm before planning an enclosure.

Channel modes

The listing says stereo input can be routed to six speakers in surround mode, while channel mode uses a six-channel input. Confirm the board's input routing and whether an external source must provide surround decoding; a channel count alone does not confirm support for a particular audio format.

Before connecting speakers

1. Check the exact supply type and voltage printed on the board or supplied documentation. Do not connect mains directly to the amplifier board.
2. Use an appropriately rated isolated transformer and supply arrangement if the board specifies AC input.
3. Match each speaker to the permitted impedance and use the labeled output terminals.
4. Do not join speaker outputs or assume a speaker terminal is ground unless the board documentation explicitly allows it.
5. Provide ventilation and heatsinking as required, and test at low volume first.

Note: This is a product overview based on the information shown with the board. Verify the precise power rating, mode behavior, pinout and supply requirements before purchase or use.
