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.

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.

how is volume, tone, treble, bass, controlled?

Asked by: altops
The TAS5630 Class-D Amplifier Board has four switch selectable gain settings for low, medium, high and very high gain (range about 500 mV to 2000 mV for full power). This is, however, not a "volume control". It's just a convenience setting to accommodate different line levels. Once you set your desired gain, that's where it stays. The amplifier board has no volume or tone controls. It is simply an amplifier. You need to control volume and tone at your audio source (PC sound card, receiver, preamp, whatever).

where do i nail down a 50VDC with necessary amperage?

Or how do I build one?
Asked by: altops
You can use the 48 VDC 12.5A 600W Regulated Power Supply (Part # 320-317). This is a switching power supply. Also, you can build your own (like I did) using a toroidal power transformer, a bridge rectifier and good filter capacitors. I built a monster power supply for my TAS5630 Class-D Amplifier Board using a 625 VA 40+40 volt transformer (part # 122-690), a 25 amp, 400 PRV bridge rectifier and a pair of 47000 uF, 50 volt electrolytic capacitors. This setup yields about 55 volts DC which is above the maximum spec for the amplifier board (50 volts max), but my board works just fine at 55V. To be safe, you should probably use a 35+35 transformer (part # 122-685) rather than a 40+40 (or just use the switcher I mentioned above). Either option will cost you about the same. If you just want to plug and play, get the switcher. If you enjoy building things, go the transformer / diodes / capacitor route. Either will work equally well.

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
Power output will be the same regardless of input voltage, so in this case it will be 160 watts RMS into 8 ohms with 24VDC input.

Will this work with a PC Sound Card's Line Out?

I read the manual and the 4 levels of input sensitivity range from 480mv to 2030mv. I thought the consumer line out standard was .315vrms which would not allow full output from the board.
Asked by: millstonemike
If your soundcard on your computer does indeed only put out that much signal, this amplifier will work, but you will likely never reach it's max wattage. It will however probably be loud enough. And also, if this sound card is not the onboard kind, and is aftermarket, then it will probably be well more than 315mvrms. Desktop soundcards are meant to be an upgrade to sound output, and one of those things commonly considered an upgrade, is to have a stronger line out signal. The only device I have never been able to get full output from my 2x100watt sure amp, was my iPhone, and that's because apple products have notoriously low output. Otherwise, you should be fine. Best of luck on your project!

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.

can this be used as a guitar amplifier?

Asked by: sirjammer
Yes although a preamp will be required.

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
Because the power supply in either case is 24v of battery, (and assuming low resistance batteries, like SLA or 'car batteries' ) - you should expect nearly identical output from this or from two channels of the 4x100 Sure amplifier - which would mean a maximum of about ~70 watts per channel before clipping into 8 ohm speakers - or around 116dB one meter in front of the Pyle speakers if they're the ones I'm thinking.

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.
