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 20 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.
Date published: 2014-01-17
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.

Can any of this Clas D amps, be used in bridge configuration?

Asked by: Delta287
this series of amplifier board is not offered with the function to use it in btl mode, but the company foresaw this and made modules that were hard wired to be btl mono channel in a different model. i have attached the model that is comparable to this model in single channel configuration. hope that this was adequate in answering your question and have a nice day.

The most power...

Hello,I am trying to run two pyle pro 12" PA speakers from batteries. I would like advise on how to power it. I am willing to go 24v, but find it a bit of a pain to go to 36v. But this amp on 36v doesn't have many peers, it appears. How would the old 4x100 sure amp (which I have experience with) sound with these speakers? (using only two channels)Thanks! Tor
Asked by: TorClausen2
I really can't tell you how an amplifier and speaker combination will "sound", but I can tell you that, at 24 volts, the amplifier will be able to produce about 45 watts RMS per channel into 8 ohm loads or about 85 watts RMS per channel into 4 ohms.The limit is the low (24 volt) power supply voltage. The TAS5630 Class-D Amplifier Board needs 50 volts to produce full output power. At the lower voltage, the outputs cannot produce sufficient voltage swing at the speaker terminals to produce full output.Since the limiting factor here is the supply voltage, I would say that this amplifier, at 24 volts, will perform almost identically to the 4x100 that you are used to.

can this be used as a guitar amplifier?

Asked by: sirjammer
A guitar output is a magnetic pickup (similar electrically to a turntable cartridge). These produce a very low output voltage and also need equalization due to the highly inductive nature of the pickup. The TAS5630 Class-D Amplifier Board has a "line level" (480 mV to 2000 mV) non-equalized (i.e. "flat") input. Therefore, the answer to your question is "no, it won't work as a guitar amplifier - unless you use a magnetic PREAMP between the guitar and the amplifier board".

can you power more than one 2 x 300 board off of the same power supply, or does it have to be a dedicated supply to each board?

example: a 7.1 theater setup where three boards are used for the stereo channels and one for the center (or a 1 x 300 if there is one)..... one or two power supplys total , or 4; one for each?
Asked by: deltarch
you may use a single supply, but it will need to have enough amperage to cover all of the modules together, In most cases a separate supply is best though.

What type of power output would this amp deliver into 8ohms at 24v?

Just looking for wattage and some sound quality insight if possible. Thanks!
Asked by: DJStronkinson
With a 24V supply, you will get about 75 watts per channel into 8 ohms before the amp starts to clip. This is because the amp is unable to put out enough voltage and current to fully drive the load. The recommended power supply voltage is 48 volts at 16 amperes (50 volts max and 52.2 volts absolute max).

What voltage does the fan run? Can the fan be removed for quieter, lower power operation?

Asked by: Kevindubbs
The fan appears to run on just under 8 volts on idle, Will high load applications it will probably go up to 12vDC.
