Product Details

4x100W TDA7498 Class-D Amplifier Board

This amplifier board features two state-of-the-art, two-channel Class-D TDA7498 ICs, which deliver up to 100 watts per channel. The small 3.6" wide by 4.8" long footprint allows this amplifier board to be used in many applications were size constraints limit the use of conventional amplifiers. Additionally, separate inputs and outputs make this amplifier board perfect for bi-amplifier use. Just add a 14 to 39 VDC power supply, signal source, and speakers!

A low noise cooling fan is mounted atop the robust heatsink to maximize heat dissipation. Thermal, over/under voltage, and current protection circuits are also included to extend the longevity of the amplifier board. Four fixed gain settings are available to allow for volume control at the source, and dual stereo RCA line-level inputs are pre-attached. Mounting holes are provided as-is a 2.5 mm x 5.5 mm power jack for quick connection. Screw-down phoenix-type terminals are included for quick speaker wire connection.

4x100W TDA7498 Class-D Amplifier Board
4x100W TDA7498 Class-D Amplifier Board is rated 3.5 out of 5 by 4.
Rated 3 out of 5 by from Awesome soundingThis is an awesome amplifier and sounds great. I can definitely feel the difference frommy tratrix speaker system after using this amp. I am not that rich enough to get fancy cabinets to host all my receivers so I decided simplify all the wiring and buya bluetooth module sold at parts express. These amplifiers do not support bluetooth modules it is a pain really when they sound awesome with all the wires connected but ones you connect the RCA to the module instead of connecting it to the actual source. In a few weeks I will post a video on youtube.

Rated 3 out of 5 by from Still untested but prospects look goodAt the time that I am writing this I have not as yet had achance to acctually power thi device up, you see right now Iam in the process of setting up a Comic Book/Anamation, and Music Studio and I am just starting to gather parts from multiple sources, the quality of this amp looks to be some of the best I have seen in its price range in along time.

Rated 5 out of 5 by from Awesome little ampBought this to use in my garage for my 7.1 surround sound setup in my garage. Since the garage was pretty big(28x30) i wanted to put 4 subwoofers in the garage for better coverage and not have any dead spots.Right now i have it hooked up to 2 JL 12W0's running at 4 ohm with a 19.5vdc 6amp laptop power supply. So far so good. I have cranked it up to the point that i couldnt stand it anymore and still was running like a champ. It also is really clean hitting.i will soon be upgrading power supply to the 36 vdc power supply that parts express sells and hope for even better things to come.The only con i have on this is the lack of a gain adjust knob. the dip switchs are ok but would like to get a lil more gain out of it while the rest of the system is at a lower volume. i really have to crank it up to get good bass feel and by that point its to loud to think.

Rated 3 out of 5 by from First AmpThis was my first attempt at building an amp. I think that everything went together as planned. The Amp works, sounds good but, I do get some clipping at higher volumes. Maybe I did something wrong.

Will this amp function if powered by a 12 volt car battery?

Asked by: Braf

can I use this amp to power a 2.1 stereo system? 100w for left, 100w for right, and 100w for the sub and then one unused 100w.

Asked by: djdaveastro09
Yes you can. You can also get a dual voice coil sub and wire each of the remaining two channels in to the subwoofer so a channel is not wasted.

I'd like to build a mono PA amp using 4- 4" speakers. Could I use this amp in mono by strapping the 4 inputs together in parallel? Would this be effectively 400 watts?

Asked by: Spence242
Unfortunately you cannot strap or parallel the outputs of this amplifier together. You will get the same total output power simply by running each channel into each 4" driver.
