In Reply to: Anthoer ohms question????70W RMS into 8 ohms...... posted by The Brewmeister on January 18, 2002 at 23:27:37:
: Hey..last one i swear!!! ha ha. What does it mean when it says: Jack paralleled with 8 ohms internal load.
70w RMS into 4 ohms. 16.73v RMS??? And when it says 8 ohms minimum external speaker... does that mean the lowes number must be 8?? what if it was 12 ohms??? sorry to ask so much guys. i am really greatfull for your help! - THE BREWMIESTER
1. What does it mean when it says: Jack paralleled with 8 ohms internal load.
Means your amp has a built in 8 Ohm speaker, and any extension speaker you hook up will be in parallel with the built in speaker.
2. 70w RMS into 4 ohms. 16.73v RMS
In your case, the most power you'll get out of your amp (with an 8 Ohm extension speaker connected) is 70 Ohms. RMS stands for Root Mean Square - It's a very good method of estimating the maximum amount of power you'll get under normal circumstances (rather than the peak power).
3. And when it says 8 ohms minimum external speaker... does that mean the lowes number must be 8?? what if it was 12 ohms???
It means the minimum impedance (Ohms) of the extension speaker must be 8 Ohms or greater. If you hook up an 8 Ohm speaker as an extension, you'll get the maximum output of your amp. If you use a speaker with a greater impedance (they're hard to find), you won't get much more output. Anything less than 8 Ohms will probably burn out your amp.
Hope this makes some sense to you.
