Product Details

6x100W TDA7498 Class-D Amplifier Board

Build your own high-power 5.1 amplifier with this 6-channel amplifier board. Three Class-D TDA7498s are used for extreme efficiency. 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 tri-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 2.1 mm x 5.5 mm power jack for quick connection. Screw-down phoenix-type terminals are included for quick speaker wire connection.

6x100W TDA7498 Class-D Amplifier Board is rated 4.1429 out of 5 by 7.
Rated 5 out of 5 by from HD FM Radio, CD, memory stick playerIt performs very well. IR remote controlled volume controls would be an excellent addition to the unit to add more versatility for volume control to multiple channels for adaptability to surround sound.

Rated 4 out of 5 by from BOOM!I made a 6 channel active Xover boombox with this amp. I used compact 8 in DVC Dayton sub with two of the channels (they don't sell just the driver anymore, but search part# 300-490 and already has a nice box and looks the same :). The other channels power Tang Band mids and tweets (the kind will grills built in). I used a 10in Dayton passive radiator (also discontinued) and an auto 3-Way Clarion crossover. I added a Rolls mini mixer for Mic/Volume duties. I used a high capacity rechargeable 12V battery with a voltage-stepper up to ~35 V so I could get about 200W from the amp+battery or power supply. I did it this way so that I could power the 12V components with the same battery. It is easily the loudest and best sounding battery boombox I can Imagine. Unfortunately, it cuts out at high-ish volume and certainly no where near 600 watts. I don't know if it is the amp or some other issue, but seems to be the amp based on other comments. Still, it works and sounds great, but doesn't seem to offer the power advertized.

Rated 5 out of 5 by from Great amp !Picked up this amp to power a boom box project. I am only using 5 out of 6 channels to power an active setup. I am using an active crossover to derive a stereo two way with single subwoofer. So far I am pleased with the soundThis little amp easily powers the tang band 5 1/4 neo subwoofer, two 4 inch Dayton mid woofer and two vifa textile 1 inch dome tweeter. It is running at 30 volts with a DC boost converter from 12 volt battery bank. As it is only powering small speakers it is running very cool to the touch so I have removed the fan from the heatsink. I played it for several hours with some punishing bass and it remains nice and cool so I will leave the fan off for my application. I imagine if you are running this amp with all channels fully driven it will heat up but for me it is not under serious load. I tested the amp powered from 12 volts and it still has a good solid sound but I recommend a good amount of current at lower voltages. This is a very flexible amp with good channel options. It is very well made with the look and feel of a quality motherboard. The sound quality is pleasing and I can't wait to find more applications to use this multi channel amp for. I am installing some outdoor speakers this year and I may have found my amp solution for that too.

Rated 4 out of 5 by from so far so goodI havent run all 6 channels yet but everything seems to be pumping out pretty good at 8 ohms. Info on these units is spread all over the place, and I've many questions.I'm trying to avoid damaging surges. If I put a power switch on the AC input am I safe in most situations ? Will this help if I remember to turn it on/off ?If I'm not using a channel is it safe to run with :1) no input2) no output3)neitherIs there an adviseable way to hack the power DIPswitch- i.e. a 3 way panel/mount switch that can toggle between on/off/mute(standby) ?I've front-mounted my RCA inputs for various reasons, and now I'm afraid someone will yank one out. This will probably cause an ugly surge. I will either:a)lock the RCA's down somehow.b) think of a way to make a buffer so I can hot-swap inputs on this amp(or switch to a 'mute' status to cut output spike ?)

Rated 5 out of 5 by from excellent valueI've used the Sure Electronics amps for a lot of projects and they have proved both durable and powerful. In one project I needed to deliver a 0.5Hz sine wave at 90W, and it did the job. It is important to note that these things are VERY sensitive to impedance: at 4 ohms with a properly rated power supply they deliver full 100W RMS per channel (sine wave). At 8 ohms, around 55W, and something peculiar: at 6ohm only about 35W. So watch your impedance, feed it plenty of juice and enjoy the incredible savings.

Rated 1 out of 5 by from Don't Expect To Turn The Volume UpThis board sounds good on paper. However, I'm experiencing the same problems documented by others and will be returning the board if I can't get this resolved.When you turn the amp. up to about 3/4 max volume, the sound starts to cut in and out. This is not the same as a normal amp that will start to slowly distort. This is an over current circuit kicking in cutting the sound off and on. I'm using the 36 volt Meanwell PS and am sure it's not a PS problem.So don't expect to be able to fully utilize the full power of this amp out of the box.The solution I'm told is to modify the output filter. I need to do some more research on what needs to be done.

6x100W TDA7498 Class-D Amplifier Board

Hi - Can i use this amplifier board for car? If yes how do i connect ? How to power up the amplifier board within which just has 12 Volts DC?

Asked by: YGANNARA

Hello, .... " Just add a 14 to 39 VDC power supply", do you have related power supply use with this amp, and how much? I plan to set up in my Toyota Camry 2012, Thank you

Asked by: Eric Ngo

i am  also planning to make a speaker system with 2 tweeter 2 woofers and 2 subs would this board work of this? and why this this board have multiple left and right analog  connectors?

Asked by: brown_bro
Being a 6 channel amplifier it has three stereo inputs and three stereo outputs. This could be used for two 3-way speakers with the correct power supply.

Other than the two extra channels, how does this Class-D amp compare to the 4x100 T-amp model AA-AB33182 in terms of sound quality and power efficiency? thanx.

Asked by: packlet
The only difference between the two is the addition of one chip and two output channels on the 6 channel amplifier. Sound quality will be identical, efficiency might take a slight hit due to the addition of the extra chip.

Can I power 2 of these boards with 1 power supply? If so which power supply can I buy? And how would i wire it?

Asked by: Djx18
Yes and no... yes you can power with 1 supply... BUT the no part is cause youll need a large and very costly PSU... best to buy 2 power supplies. remember its at 36v and up to 18 amps. so in order to use 1 PSU youd have to have 36v @ 36amps of power. parts express only carries 36v @ 9.7A so youd need 2 of them to run on 1 board. if i may ask... what are you using it for, and what speakers are you powering?
