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.

I am interested in running this amp off of a battery and wanted to know what would be the best way to do this.  Can I use a 12v battery and 12V to 48V DC-DC converter?  

Asked by: AlexVW
You could although that would be a very inefficient method. You would be farther ahead wiring two 12V batteries together in series for a 24V load and wiring straight to the amplifier.

Running different resistances on each channel and 16 Ohm power

I'm interested in this amp for a transducer setup. Is it possible to run one channel @ 4 Ohm 300W (Buttkicker Mini LFE) and the other channel with whatever wattage is supplied at 16 Ohm (2x Dayton Puck in series). For that matter, what is the rated output at 16 Ohm?
Asked by: FredRex
Yes, you can run a different kind of load on each channel. You would get approximately 76 watts RMS max power into the 16 ohm load. Note that the volume (loudness) from each channel may not seem to be the same. Detailed explanations follow:Although the TAS5630 chip is one device, it actually contains four individual amplifier blocks inside. The normal configuration is two internal channels connected in push-pull (BTL) for each audio channel (left and right). Therefore, each audio channel in electrically independent and there is no reason why you couldn't run one kind of load on one channel and a different load on the other channel.As for output power into a 16 ohm load, if you take the supply voltage (50 volts) and divide by 1.414, you get approximately 35 volts "RMS". The speaker (or driver) current at 35 volts is 35 / 16 = 2.2 amperes. Multiplied by 35 volts, you get approximately 76 watts RMS max into a 16 ohm load.To calculate the power for any load, use this formula: P = (V * V) / R (where P is power, V is the RMS voltage and R is the resistance of the speaker).So, as an example, into an 8 ohm load, you would get about (35 * 35) / 8 = 153 watts RMS, and into a 4 ohm load, you would get (35 * 35) / 4 = 306 watts RMS (hence the 300 watts per channel specification for this board).Lastly, notice that for a given input signal, you would get (for example) 300 watts into a 4 ohm speaker but only 76 watts into the LFE driver. This may end up sounding "mismatched" (one too loud, the other too quiet). Therefore, you may want to use an audio taper potentiometer (volume control) on each input to "balance" the power going to your two different loads.Hope this helps!

Can you adjust the DC offset on these boards? Mine measures around 135 mV on each channel.

Asked by: Dirkl
The specs for the TAS5630 Class D amplifier chip allow for up to 150 mV DC offset on the outputs. Therefore, your board is operating within spec. Unfortunately, there is no adjustment on the board to null the offset to zero. Don't worry, that tiny offset will not damage your speakers!

Will this amp fit into the Sure Amp Case (1.77" H x 4.72" W x 6.89" D)?

Was wondering if this amplifier would fit inside the Sure Aluminum Amplifier Case 1.77" H x 4.72" W x 6.89" D?
Asked by: Switch
No, it will not fit. The 2x300W TAS5630 Class-D Amplifier Board (with fan) is too tall. With the fan removed (not recommended), the board will JUST fit, but there would almost zero clearance for any other parts. Remember that you would need to install RCA audio input jacks, 5-way binding post speaker connectors, a (hefty 60 volt, 15 amp) power connector, a volume control pot or encoder and an on/off switch. There would be no room for these parts. Additionally, the amplifier, if sealed up inside that case, would get no airflow and no cooling. It would overheat. The 2x100W TDA7498 Class-D Amplifier Board (Part # 320-303) would be a possible choice for installing into the Sure Amp Case. Keep in mind that any amp board is going to need cooling, which you can accomplish by thermally coupling the amplifier heat sink to the Sure Amp Case (using the case itself as a heatsink). Of course, modifying the amplifier board in any way will probably void the warranty, so be careful.

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.

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.
