Tool/software:
I am looking for amplifier board -TPA3116D2EVM — 50-W Stereo Analog Input Class-D Audio Amplifier Evaluation Module for PA System project, But not sure if it will fulfil all my requirements.
I need minimum 50watt output , what will be the power requirements?
Does my P.A. system Line In signal(Provided by 3.5mm jack) will be sufficient for amplifier input or i have to add a preamp?
Is 50W per channel sufficient for the size of my PA coverage area?
Do I need stereo output or should I bridge the amp for a mono PA system?
What power supply (voltage & current rating) is ideal for this board in my use case?
Is the board protected against speaker shorts, over-temperature, and input overvoltage?
What kind of enclosure or thermal management will I use to protect the amplifier board?
Does the board introduce any audible noise in idle or at low volume?
What speaker impedance (4Ω or 8Ω) will I use, and how does it affect output power?
What is the max supply voltage I can safely use to get full power output?
System Integration Questions
What is my signal source — microphone, line-level device, Bluetooth, etc.?
Do I need onboard signal conditioning (e.g., EQ, filtering)?
Do I require input gain adjustment?
Does it need additional EMI shielding for use in noisy environments?
How will I mount or package the board for field use?
Do I need certification (e.g., CE, FCC) if deploying commercially?
What is the board’s idle power consumption when audio is not playing?
Can i use it for 70/100v Spk Line System by using Transformer at Output?
