[Q] What is DIN and this circuit board

[dtronicsuk]

Hey guys,

 

i have something that has been bugging me since i got these speakers but

 

on the back of the speaker it says input:160w .music: 80w .DIN

 

i understand that the max input is 160w but what is the DIN. my only thinking is that DIN is the max RMS input but i dont know. i have attached a picture for you to look at if you dont get me or are like me confused.

 

 

lastly i have noticed that at the back of the speaker is a little PCB with 3 coils, 3 caps and 2 relays, does anyone know what this PCB is/does, my thinking is some sort of filter or current protection (because of the relays) again i have attached some pictures just see below

 

cheers

p.s. if this is not the right forum im sorry but it did say speakers and thats what this is about lol

 

once again cheers

DIN may refer to the connector used.

This is a 2 pin din:

dunno, there is no din connector on the speaker just your normal red and black speaker wire terminals

Just found this:

"The typical crossover unit from a loudspeaker: The frequency is divided up by inductors and capacitors and then sent on to the woofer, tweeter and mid-range driver."

So the PCB is a crossover unit to separate the different frequencies.

 

also the white 'relays' are ceramic resistors

thought so just weird how mine has coils and a relay lol

ahhh that makes sense cheers. any info on what the DIN is, its some sort of power rating i think

DIN (Deutsches Institut für Normung, German Institute for Standardization) describes in DIN 45xxx several standards for measuring audio power. The DIN-standards (DIN-norms) are in common use in Europe.^[10]

Its just the RMS wattage of the speakers as a unit.

ok so 

 

160w is the max burst power and the 80w DIN is the max continual power, am i correct?

yep, that should be right.

 

 

Just keep in mind that manufacturers use all sorts of weird equations in order to get their ratings.  Some get the max wattage by multiplying the rms value by the number of rainy days in the UK then add a few for good measure, while others get the PMPO figure by taking the original RMS value and multiplying it by the number of seconds in a 4 year period and dividing by the number of spanners in a sidcrome tool kit.
