Product Details

2x300W TAS5630 Class-D Amplifier Board

Just one look at the power input terminals and you will know that this amplifier board means business! A Class-D Texas Instruments TAS5630 with PurePath™ HD enabled integrated feedback is used to deliver 300W to two channels, effortlessly and efficiently. This amplifier board works amazingly well with both low sensitivity speakers and subwoofers.

A robust heatsink, two-stage cooling fan, as well as protection circuits to protect against over/under voltage, over current, short circuit, and over temperature conditions are built-in for years of enjoyment. Four fixed gain settings allow you to match the amplifier to your source, and use your source as the volume control. A 25 to 50 VDC power supply is required.

Note: The minimum recommended wire gauge to be used for power is 16 AWG.

2x300W TAS5630 Class-D Amplifier Board
2x300W TAS5630 Class-D Amplifier Board is rated 4.75 out of 5 by 4.
Rated 4 out of 5 by from it definitely needs a large power supplyI bought 2 of these, not really sure where to use them. Still don't know. I also bought 2 of the 300 watt DC voltage boosters to go with them. I sorta kinda thought I might make a pair of powered main speakers, but when I hooked up a 24 volt supply, it was obvious it needed a 48-50 volt supply. I'm still in process. They work as advertised, appear to be excellent quality.

Rated 5 out of 5 by from Very Well-BuiltThis amp does exactly what it's advertised to do. It WILL pump 2X300 watts into a 4 ohm load as long as your power supply is strong enough. All of the electronic components are very secure. My favorite feature is the built-in circuit breaker that kicks in within seconds of an overloaded circuit or in the event of the power supply pushing more than 50 volts. I'd recommend this amp board to anyone looking for a simple power amp with a very small footprint.

Rated 5 out of 5 by from very good amp boardI got a few of these amps before and they are loud. I'm using the amp with a 48 VDC 7.3A 350W Switching Power Supply and its still rocks.

Rated 5 out of 5 by from Nice clean and powerful amplifier!I had a dead stereo power amplifier and wanted to "rebuild" it into a working amp again. So I used the existing toroidal power transformer, a pair of 47000 uF, 50 volt capacitors and the 2x300W TAS5630 Class-D Amplifier Board.I powered up the amp board - it just worked. The board sounds nice and clean. Lows pound through, and I can hear the highs crystal clear without any distortion. I can crank it up as far as my limited power supply will allow and the board just works - and works cleanly.I know the board is Class-D and efficient, but wow... it doesn't even get warm when cranking about 150 watts per channel into a pair of 8 ohm dummy loads. I can't get more than that now (explained next).Last thing I need to do is upgrade the power transformer. The old amp only has a 25.8 volt transformer which gives me about 35 volts at the capacitors (Vrms * 1.414). I'll use a 40 volt transformer with a higher VA rating to power the amplifier board to it's fullest.

Is it possible to run this amplifier in bridged mode?

Asked by: THR2
No, this amplifier is not bridgeable.

can this amp run 140w max input 8hm speakers?  also, how well would a 20ah 24v battery work? 

Asked by: Johnsmothhh
Yes this will drive a 140 watt speaker. As long as you recognize the speakers limits you will not have any problems. A 20 Ah 24V battery will work fine for a few ours of playback.

If I run two 12V batts in series to power this with 24V, what would the current draw be, roughly?   Would I be better of with 3 batts and 36V?  I'm looking to build a portable, rechargeable boom box of sorts... 

Asked by: Mxseven
The current will remain the same as the voltage will double when wired in series.

This may be a stupid question but could this amp be used like a 2.1 amp running two book shelf speakers and a 10" sub? I already have the Dayton 2.1 plate amp but the sub needs much more power. 

Asked by: Manly man
This is only a 2 channel amplifier so it will only work with a passive subwoofer and satellites. You might be farther ahead getting a dedicated subwoofer amplifier if your subwoofer requires more power.

Can this amp be used in a 4 x 150W @ 4Ohms application, such as 4 x Buttkicker Mini LFE's?

Asked by: Griffin5
Yes this would work for an application like that.

Ill need to buy four of these and will need to power all four completely. What power supply will I need.

Asked by: Mike22
The power supply we recommend for each of these amps would be in the link below.http://www.parts-express.com/48-vdc-125a-600w-regulated-power-supply--320-317We do not have a single power supply that will power multiples of these.
