well, if it's rated for 100Wrms per channel, you need at least 10A on 24V. Anything below that and you'll be clipping before the bass drops.

If you want 100W/chan from the TDA7498 you need a pcb with decent sized filter inductors than can take the current, 6 ohm load and a decent 36+V supply. Most of the boards have small inductors, should handle 50W into 8 ohms or so. Note that the 100W rating is for an unrealistic 10% distortion, its 78W/chan really with 6 ohms and decent passives. Its pretty decent chip, very low noise for a class D single-chip amp...

Anyone who is buying these boards the resistors under the heat sink R3 and R4 ( non Bluetooth board) need to be modified. On the non Bluetooth boards R3 needs to be removed and R4 needs to be swapped to a 5.6k resistor. This eliminates the noise floor hiss that everyone keeps talking about. The Bluetooth boards also can be added an antenna to increase the Bluetooth range. You need to add some hotglue on the corners of the inputs and outputs to secure the sockets.

I've built several portable speakers with amplifier boards from China, and there is good stuff made there. Sure Electronics/Wondom make excellent amplifier boards. Shipping time varies depending on how soon it's loaded on to the ship. If it's loaded last it ships fast, if it's loaded first it has to wait until everything else is loaded before it starts to move. Customs can also delay things. It's not the fault of the shipper.

That being said, why don't you make another video where you do it right? Connect it properly to two speakers and an 18- 24 volt power supply, use the volume adjustments and see how she does?

These amp boards can be useful, but you have to know them for what they are. The rating convention used by the IC manufacturer is different from what is common for hi-fi home audio. As you know, amplifiers don't just reach their maximum power and then stop increasing - instead, it is possible to drive the amplifier into "clipping", which causes a rise in distortion that marks the end of the available power from the amp, but it is a soft knee rather than a sharp increase, so you can get a small bit of extra power from an amplifier if you are willing to accept more distortion (THD). Home audio amplifiers are often rated where their THD crosses a threshold of about 0.01% THD, but in less critical audio applications, some users can accept a THD of up to 10%, and while 10% THD is audible at high and midrange frequencies, it is not considered to be audible at subwoofer frequencies (deep bass). The IC manufacturers use this higher 10% THD threshold so they can rate their amps a bit higher in power, but for the THD to be considered "low" for home audio applications, the maximum power the amp can be rated to supply will be less, on the order of 20-30 watts (which, when compared to 50 watts, is only about 3 dB less in actual sound). Still, if you know about speaker sensitivity, and that most home audio speakers can deliver 85-88 dB with just one watt input, and that's already pretty loud, when you do the math these amplifiers deliver plenty of power for real-world home audio listening. They aren't any "worse" than other home audio amplifiers, they are just rated more aggressively (to sell chips) and they can indeed deliver that power, just with higher distortion, and to meet a low distortion target the actual output power will be less.

Interesting video, The output cannot exceed the supply, at best it's only a 2amp mains adapter. Calculate with Ohms law the maximum output. Remember to test the unit at it's maximum operating voltage of 24vdc. That tiny heat sink could not hope to dissipate the high heat generated from the 'fake' 2x 120 watts quoted in the eBay advert. Can't really fault the board though, they work and at the price purchased, it's just the ticket to use as an effective 'preamp' for larger amplifiers. PS. Can't believe you were wiring your speaker cables in while the board was powered.

Hey doublesmm, I know this is a bit of an older video but I'd actually love to see ya do something with this board! I have a 2 x 6.5" speaker box made by a company called sondpex, also has "3 inch tweeters" which are actually just small piezo drivers screwed to a 3 inch plastic horn. The box claims to handle 400w but there's no way, I say 100w rms max. A few years back the company Dual made what appears to be the same product; more then likely made in the same factory from identical designs. Anyhow, I found myself in possession of two of these boxes; $15 a piece in like new condition. I figured it was worth it for the boxes alone. I pulled one apart the other day and was pleased to find a divider in the middle for actual stereo separation. I went to town with spray adhesive and a small layer of polyfil inside the box, and comparing the one I filled to the factory one is actually pretty surprising. I intend on buying a decent 6.5 component system with crossovers and upgrading the mid-woofers and tweeters whenever the garbage (basically Dual) speakers blow. After that I'd like to buy a Bluetooth amplifier board similar to yours, and build a massive 4s li-ion battery pack out of recycled cells. Then it's just odds and ends. I can salvage a carry handle from a broken guitar amp, and buy a 4s BMS and buck/boost converter for cheap. Then I'd use an old cigar box as an enclosure for the amp/battery/electronics, and attach it to the back of the box. If you can tell what I'm getting at, I'm trying to build a Bluetooth boom box of sorts, capable of diamond-box volume levels (I didn't say sound quality!) and 16-20 hours of battery life depending on how hard you're pushing the speakers. If you read this far doublesmm you're a saint!!! Greetings from Michigan, love all the content dude! Keep it up please, and let us know if you've still got that Bluetooth board? Is it in use today? Collecting dust in the closet?

maybe I'm a bit late to the party, but what power adapter are you using? I was planning on buying a 24V 6A cause I don't find anything more juicy for a 2*100W amp...

Dude.. You can just use longer screws if you don`t want to solder the wires in place :p

"doesn`t do 100watts" Well how many volts do you put into it, and how many ohms are your speakers? Those things are worth a mention..
@afrog26667 жыл бұрын
probably powered it with 12V 2A lol.. You need voltage for this thing if you want 100W. 19V 5A from a pc adapter would get you close..

You should plug off the power supply before approaching with any metal in your hand as you can easily short-circuit something and destroy it. You paid 16 dollars for the whole thing, they just added the working parts, they did not add fool-proofing, you should be smart enough to use those things with the price of 16 dollars. Or go buy one that has similar rms with 500 bucks and just plug in carelessly, insert speakers easily and do not think about the rest. You did not pay for these, so do not expect something that you did not pay for.

You haven't even screwed the wire in.. You did it the wrong way.. Those terminals is pretty descent! And it doesen't do 100W RMS, it does around 2x50w RMS with 21V and 25w at 14,4v

And by the way there buddy RMS is measurement in voltage not in watts of amplifier power

next time try to connect the speakers the right way... in the beginning when you said the connecters were all the way open, they were really all the way closed.. you connected the speakers in the worng side of the connector
