# WONDOM AA-AB35511 3-Channel Class D Amplifier Board

The WONDOM AA-AB35511 is a three-channel Class D amplifier board for DIY audio builds and cabinet integration. Its listing claims 500 watts per channel at a 3-ohm load and 50V DC with THD+N at 10%, but specifies a lower 312 watts under a 1% THD+N condition. Buyers should distinguish those test conditions and plan for a suitable DC supply and speaker loads.

## At a glance

- Three-channel Class D board intended for DIY audio projects and integration into a cabinet.
- The listed maximum output is conditional: 500W at 3 ohms and 50V DC with 10% THD+N, versus 312W under the listed 1% THD+N condition.
- RCA and line inputs, plus pre-mounted terminal interfaces, are described for connecting audio and speaker wiring.
- A temperature-controlled fan, heatsink and overcurrent and overtemperature protection are claimed.

## Pros

- Three channels in a compact board format can suit a multichannel build, including the listed 2.1-system use case.
- Four screw holes and pre-mounted terminal interfaces are described to simplify cabinet installation and wiring.
- The product description specifies a lower power figure at a 1% THD+N condition, helping distinguish it from the higher 10% THD+N claim.

## Cons

- A suitable DC power supply is required, and none is listed as included.
- The advertised 500W figure is tied to a 3-ohm load, 50V DC and 10% THD+N. It should not be treated as the stated output at the 1% THD+N condition.

## Before you buy

- The listing gives different weight values, 757g/1.69 lbs \(±10%\) and 767g/1.69 lbs \(±10%\), and describes the indicator inconsistently as a power indicator or clip indicator. Its claimed 500W-per-channel output also has specific load, supply and distortion conditions, with 312W stated at 1% THD+N. Confirm which revision and details apply to the selected listing. The product description calls for a DC24V – 50V supply.

## A good fit for

- DIY audio builders seeking a three-channel board for a 2.1 setup, soundbar, home theater or custom cabinet.
- Buyers comfortable sourcing a compatible DC supply and checking speaker load and power requirements against the stated output conditions.

## Less suited to

- People seeking a ready-to-use amplifier with an included power supply or finished enclosure.
- Buyers who require a guaranteed 500W output at 1% THD+N, since the listed 1% figure is 312W under the stated test conditions.

## Customer feedback

The supplied rating evidence is a single five-star rating, which is too limited to establish broader customer satisfaction or identify particular strengths and concerns. It provides no explanation of how the board performs in a build, so buyers should base fit on the stated three-channel format, power conditions and installation requirements.

## Frequently asked questions

### Does the board provide 500W per channel at all distortion levels?
No. The listing specifies 500W at a 3-ohm load and 50V DC with THD+N at 10%, and 312W with THD+N at 1% under the same stated load and supply conditions.
### What power supply does it need?
The product description says a DC24V – 50V power supply is required. It does not list a supply as included, so buyers need to source one separately.
### What connections and installation features are stated?
The listing describes RCA and line inputs, pre-mounted terminal interfaces, and four screw holes for installation.
### Is this a complete amplifier system?
It is listed as an amplifier board. The description discusses integrating it into a cabinet and does not identify a power supply or enclosure as included.
