Product Details

TDA7492 Digital Audio Amplifier Board 2x50W

Originally designed for high-end televisions, this tiny amp board delivers 50 watts into two channels, or an impressive 100 watts into a single channel. Use this Class D amplifier in DIY projects where high power is needed in a limited space.

The board includes a massive heat sink, and three dual-terminal phoenix connectors for easy termination of speaker lines. Included in the box is a 12" stereo input lead, making connection a breeze. Depending on the voltage powering the unit, you will need 1A to 4A of current.

Note: When the speaker impedance is 4 ohms, the operating voltage must be less than 18V. When the speaker impedance is 6 ohms, the operating voltage can not exceed 24V. When the speaker impedance is 8 ohms, the working voltage can not exceed 26V.

Specifications: Power handling: 2 x 50 watts @ 8 ohms, 1 x 100 watts @ 4 ohms • Minimum impedance: 4 ohms • THD: 0.1% @ 8 ohms @ 1 watt • Recommended power supply: 10V - 26V • Requires 1A - 4A • Stereo wiring harness included • Dimensions: 2-3/4" L x 2-5/16" W x 7/8" H.

TDA7492 Digital Audio Amplifier Board 2x50W
TDA7492 Digital Audio Amplifier Board 2x50W is rated 4.0 out of 5 by 9.
Rated 3 out of 5 by from OK Amp. TPA3116 is betterif you need 25- 30 watts a side and this is not a bad amp. it will go to 50 but it is ugly. For a few more buck use the Yuan-Jing TPA3116 Class D. The TPA3116 put out a true solid 50 watts. I use this and the TPA3116 to drive the ADX Shaker which feels Great.

Rated 5 out of 5 by from Good sound for the pricePacks a punch for the size and price. Powering it with an 18 volt laptop power supply

Rated 4 out of 5 by from Very good soundI would give it five stars if it had a 3.5mm input. The sound quality is very good and the extra power rocks! I've tried a number of ac adapters and it loves the 15 volt I have from an old iHome clock radio the best.

Rated 3 out of 5 by from Cannot hook up as a mono 100w. amp.Catalog description says it can be used as a 100w. mono amp. This is not possible.. Only as a 2x50w. amp.

Rated 5 out of 5 by from Good bang for your buck!just purchased a few of these little guys, hooked one up to a 140watt 3-way speaker on a single channel and it sounds great!! thanks PE!

Rated 4 out of 5 by from Nice Little Amp, more like 35W/channel into 8ohmsI was surprised at how small this amp is. That said, it is not able to deliver 50W/channel into 8ohm. Figured I would offer a bit more info for others looking at this amp:35W/channel into 8ohm from a 24V supply.47W/channel into 6ohm from a 24V supply.50W/channel into 4ohm from a 20V supply.If driving into 4ohm loads, make sure to use a supply voltage under 20V!The output filter is optimized for 6ohm loads.Gain is set to 33.6dB.Inputs are single-ended, not differential as shown in the schematic. Make sure your source ground/return is good.Check the heatsink screws: I received 2 of these, first one was over-torqued, bowing the PCB, Second was uneven with the heatsink tilted and barely touching the chip. Easy enough to correct. Put some thermal grease in there if you have it.While not quite as advertised, this is not a bad little amp.

TDA7492 Digital Audio Amplifier Board 2x50W

I added a revision to my question but it didn't post! I forgot to mention that I will be using at 4 ohms and the product description clearly states an 18v maximum. Can you please recommend a power supply?

Asked by: djdaveastro09

I would like to have 3 inputs to the amp. a. mini stereo jack, b. USB MP3 Module , and c. a Bluetooth module. Thought about just connecting all three to the inputs . Would prefer to be able to select input. Any thoughts on how to wire?

Asked by: dougi6

Are there any power modules you could install internally, as in inside a speaker enclosure? I have looked at transformers here, but I think they are AC in snd AC out. Any options for this idea?

Asked by: James Wright

Will this accept a microphone input or do I need a preamp?

Asked by: Capacitor Guru

Will this guy do the trick? 129-014 If not is there a power supply that you recommend? Thanks.

Asked by: djdaveastro09
In order to get the most from the amplifier I would recommend the power supply below.http://www.parts-express.com/parts-express-24-vdc-5a-switching-power-supply-with-25-x-55mm-plug--120-055

Where is the power input? Can I wire the Stereo harness to an aux cable?

Asked by: bruce123
A wiring diagram for this amplifier is below. Yes you can wire the harness to a 3.5mm aux connector.www.parts-express.com/pedocs/tech-diagrams/320-606--tda7492-wiring-diagram.pdf
