Speaker Impedance?
Hello,
Just wondering if it is safe to hook up my Logitech X-230 speakers to a DAC/Amp that I had purchased.
The USB DAC/AMP that I bought was actually meant for headphones, and there is a warning saying not to use headphones with less than 30 ohm impedance on it.
I'm just wondering how that translates to speakers? The only info I could find on my speakers were the following, and I have no idea what it means.
Total RMS Power: 32 Watts
Subwoofer: 20 Watts RNS ibto 4 ohms at 100Hz at 10% THD (total harmonic distortion)
Sattelites: 12 RMS (2x6w) ubti 4 ohms at 1 KHz at 10$ THD.
It is the Logitech x-230, with 2 speakers and a sub. It has its own power cord hooked up to a power outlet. The DAC/Amp I have is the HotAudio USB1.
So would it be safe for me to hook it up to the DAC/Amp? How do I determine if the speakers have an impedance of 30ohms or more?
Thanks!

Your speakers impedance is 4ohms as you stated. I don't think it is a good idea to plug these speakers into the Amp...since you might blow the Amp.

I went through this nightmare. You will need to do some research if you don't want to damage any equipment. Search out "impedance matching transformers"
After blowing a nifty amp, I did the research so I could hook up two 4-ohm Thiels and 2 8-ohm ADC speakers to an older Threshold Class A amp. The result was to buy two impedance matching transformers which guarantees that the amp always sees the ohms it wants, regardless of the speaker configuration. Within guidelines, of course.
The math formulas escape me, I simply do not remember them. Hopefully an engineer will chime in our your question. If not, happy hunting on the net. The info is out there in audiophile sites.
Good luck and happy listening.

It ability that the ear telephones will positioned an approximate 40 4 Ohm load at audio frequencies on the element interior the circuit that the ear telephones are linked for the time of. in case you're utilising the headphones for merely monitoring then the better the impedance of the headphones the fewer it is going to load the circuit and the greater advantageous off you would be. yet once you venture approximately audio constancy from the headphones themselves then you definitely would desire to decide on headphones with an impedance that suits the output impedance of the element interior the circuit the place the headphones are linked. inspect the training on your iphone 4 for specific training.
