2x100W at 4 Ohm TK2050 Class-D Audio Amplifier Board Only
Constant Power Supply to Amp
Hopefully someone can help me with this one, this unit seems perfect for my needs except for one little catch.I'm looking to use this for a remote PA style system, where the amp will have a line in signal sent to it from a computer quite a distance away to the amp and then a short run from the amp to the speakers. What I need to know is, regardless of the power supply I decide to use, I have no way of turning the unit off and on to receive the music. Which means that while there is no audio line being sent to it to amplify, it will still effectively be turned on. Is this going to harm the amplifier?If it will does anyone know of a solution or different user that sort of goes into standby when there is no line in source?Appreciate any advice anyone can give.
No problem amp is on standby when no input signal is present.

car audio install
Hi there, will this amp work on a car audio installation work with a standard 12v to 14 v? regards
Yes. But do read the manual - there is a lot of detail on the power supply. You must have a good power supply for stable current delivery, and batteries that maintain voltage. If you don't, you'll experience clipping, soft distortion and less than full output. Mobile amps have very specific power supplies - study them all and have fun with your project

I want to use this amp with a 24 VDC battery charger@10 amp . and filter the output with two 33000 uf computer grade electrolics. Do you have a problem with that?I only guess that the PS needs 24vdc plus and minus because i see the tiny little coax socket is recommended as input. .By the way, Class d? I am after high quality reproduction of my music.Is this as good as my Dayton APA 150?
There are many configurations to power an amp board. Unless you are doing an exotic mobile application - I suggest you stay with the recommended specs and proper boards to assure amp performance. As for sound quality. Class D is typically used for subwoofers and car audio due to the high output and low power consumption capability. With the exception of very expensive Class D amps (talking over $1000), traditional Class AB designs will be more musical. If that is your goal - the Dayton 150 will be the better choice.

Would I be able to use a DC 12V to 24V Step-Up Power DC-DC Converter
For the 2x100W @ 4 Ohm TK2050 Class-D Audio Amplifier Board Only product. I want to use a 12v battery and them set it up to 24v. Is this OK.
Yes, you may use a DC-DC converter with 24V output to drive this 2x100W amplifier. The amplifier board just needs a single relatively clean 12 to 32VDC power source. With a 24V power supply this amplifier will produce a maximum output that is about half of the rated 100W/ch. The power supply will need to supply as much as 4 amps of current if you are driving a 4-ohm load, (less if you are driving a higher impedance). This is a back-of-the-napkin estimate.

What is this board intended for?
Im confused, it is listed under 'home electronics', but it says DC as the power supply and everyone is mentioning batteries. Doesnt that mean its for use in an automobiles system? If so ignore this next question, if it can be used in home setups, where is the plug? Im new to this so go easy on the insulting remarks about my ignorance.
There are a lot of products at PE that may appear new - it's like anything - until you become aware of or familiar with - it's an odd looking device. Can you imagine showing an iPad to someone 20 years ago? Same thing. So you're okay. So if you were to open a stereo receiver - you'd probably find a board in there similar to this in appearance. That is the "amplifier" section. You have up front the controls and tuner, the preamp and volume control, then the amp which runs the speakers. And an amplifier board needs power. So typically one corner of a receiver is heavy. There's a power supply there that plugs into the wall to feed not only the entire receiver - but the power amp board as well... So to make this TK2050 board work - you need a source with volume control, the board itself, a power supply and speakers. Some guys use them at home with power supplies that plug into the wall, others are doing creative mobile things with them using batteries - a bit trickier. As a novice - this may be something a bit too adventurous for your first project - start off by reading all the QA threads on this and the other boards. You will learn a lot from the conversations. Good luck with your project.

No Audio or Turn-On Pop from Amplifier Module...??
I am not getting anything out of either output section of my amplifier module. Status LED comes on, as does the Fan, but still no "turn on pop" or audio whatsoever. My plan was to use this with a 12V supply, going against recommendation, for use with a battery. I have tested the amplifier with a 12VDC2A power supply, 12.4VDC5Ah Lithium Ion Battery, and 24V2.5A power supply. Every power source seems to turn the status LED on and start the Fan, but still no audio or turn on pop. Any suggestions? Theres a pin that reads "mute" on the PCB, but its next to a +5V pin?? I can't seem to find any information on installing a Mute switch anywhere. Why no audio or pop?
My guess is that you are expecting a noise when you turn it on. Try an input to test operation. If that fails contact PE tech for possible exchange.
