soundsystemaniac Posted December 25, 2011 Report Share Posted December 25, 2011 I wish there was a device that can tell you what kind of power each channel puts out. Not AD-1, but something like if you have 4 channel amp and each channel does 100wrms @ 4ohm, but speakers can only take 80wrms @4 ohms, you would just plug in the device and turn the gain up until it's gonna show that it's 80wrms There is, its called a clamp meter and digital multimeter. Once you clamp the amp you will know the power the amp is making. There is now way to really tell other then that due to a speaker being a variable impedance, and with every frequency the speaker plays will result in a different amount of power being giving to the speaker. A Another words if you are 100% sure the amp is making 80watts rms at 60hz, it does not mean it is making 80wrms at 100hz, or 50hz. I wish at least the power at xx hz is consistent lol, or that they made something like a chart or something on amps and or subs that say...at this hz, this amp will make this power, and this sub will handle this power, and have it written in a way that everything just stops at a volume level of less than 1% thd and not be able to go any higher. Of course, i know that then again, all of those will vary dependant on different voltages, but i think there should be stricter regulations for specifications and ratings.

kirill007 Posted December 25, 2011 Report Share Posted December 25, 2011 A amp will produce a almost even wattage across 20-20,000hz. (although there are some amps that don't...) The reason why a amp will make X wattage when connected to a speaker is because of the impedance curve. Quote Thinking is the root of all problems... You ALWAYS get what you pay for.

dB Don Posted December 26, 2011 Report Share Posted December 26, 2011 I wish there was a device that can tell you what kind of power each channel puts out.

This one works and it does take a few seconds to read so it does not record peak burst power. http://www.testequipmentdepot.com/extech/clampmeters/380940.htm If there was anyway Tony could make a better one I am sure ALOT of soundoff orgs and competitors would purchase one. Currently in dB Drag we are having a tough time creating power based classes without a consistant method to classify people if we go with power classes. We cant agree to go with power classes until we find a quick method to measure power that will be the same across the planet for everyone. Steve or Tony, maybe at CES you could discuss this with Wayne Harris. There is definitely a market for an affordable power meter that has a readout and could be used in the lanes of many Sound-off orgs.

A Another words if you are 100% sure the amp is making 80watts rms at 60hz, it does not mean it is making 80wrms at 100hz, or 50hz. true, just like there is an oscope What I mean is a device with lcd display that does all of the calculations for you. So all you need to do is plug in and play. calculations? Its AC Amperage X AC Voltage = POWER. This thread makes baby Jesus cry! lol Merry Christmas SMD peeps! You too bro! That is actually wrong, I used to think the same until someone(Tony) shed a lil light on it. I felt like an idiot after he explained cuz I knew that, just ignored it lol. Anyway AAC X VAC = VA(volt-ampes) or apparent power AAC X VAC X pf = real power(Watts) pf is always less then 1, that is the cosine of the phase angle of the voltage to current sine wave. You take the cos of that phase angle and you have pf(power factor). Clear as mud?
