Product Details

Sure Electronics AA-AB34181 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.

Sure Electronics AA-AB34181 6x100W TDA7498 Class-D Amplifier Board is rated 4.25 out of 5 by 8.
Rated 5 out of 5 by from Great for 5.1 home theaterI paired this amplifier with an ASUS Xonar DX 7.1 Channel Sound Card to provide surround sound for my home theater. Even on its lowest gain setting I can shake the house with the sound card output at 50%. There is no hum, no feedback and the unit runs quite and stays cool even after hours of watching movies.

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.

Is it possible to add Bluetooth connection and Optical input to this board ?

Asked by: NickDG
Sure Electronics will provide customized service but the MOQ will be required. For retail customers, it is suggested to use another Bluetooth board with this amplifier board. For the Optical input, Sure Electronics can provide WM8804 S/PDIF Converter.

Can I use this to make my own sound system for my tv, if yes what would I need?

Asked by: Chivas24
This board can only accept RCA and terminal blocks input instead of optical input. So please kindly confirm if it is ok for your TV. If yes, you may need a 36V power supply, speakers and some speaker cables.

Hi, what size wire should be used to power the board if not using the power input jack, and using the NES-350W-24 power supply? It seems to have melted the wires that came with the power supply, due to high current.

Asked by: Spiddy
It is suggested to use 18AWG cable to work with this power supply due to high current.

Hey guys, I'd like to use this to give 40W to six 4 ohm full-rangers. Is that possible? If it is, would a 15V, 20A SMPS power supply be sufficient? Thanks!

what gauge power wire should I use for this amp? I plan on using two SLA 12v batteries for 24v, what gauge wire should I use to connect the batteries to the amp? 18 gauge? 16 Gauge?  14 Gauge? 12 Gauge? 10 Gauge?

Asked by: Amp Question
I would recommend 14 gauge for this application.
