6. 16 Appendix Technical Info Do The Math Ohms Loads and Such An ohm is a unit of resistance the more ohms the more resistance or more accurately in this case impedance The more the resistance the less the power If you re dealing with just one speaker or cabinet per output the load in ohms is usually printed on it somewhere That s your load usually 8 ohms or 4 ohms If you re driving an assortment of speakers things can get complicated There are two basic ways of linking multiple loads or speakers in this case series and parallel Since series connections are not normally used in PA applications we ll concentrate the parallel connection Parallel means that the positive amp output connects to the positive terminals of all the speakers and the negative amp output connects to the negative terminals of all the speakers If one speaker fails in a parallel configuration the others will still work Calculating parallel loads is easy as long as each speaker has the same value just divide the value by the number of speakers For instance four 8 ohm speakers connected in parallel will equal 2 ohms 8 4 2 If the loads are not all the same the formula gets little more complicated but nothing that you can t do with a simple calculator 1 Poe 1 1 1 21 4 B Using this formula an 8 ohm speaker and a 4 ohm speaker connected in parallel will egual 2 7 ohms Rememb

Try switching sides Turn off the amp swap the speaker cables at the amp turn the amp back on If the same side is still louder the problem is with your speaker cabling If the other side is louder now the problem is with the mixer the amp or the line level cabling The stereo music sounds kind of sideways and the bass frequencies diminish when standing center but get louder as you approach one side Check the polarity of the speaker cable connections You may have your positive and negative reversed at one end of one speaker cable As soon as the music gets loud the amp shuts down Check the OL LEDs and make sure that they are not lighting continuously If they are turn down the signal source or the Level controls on the amp the amp breathe The amplifier draws its ventilation air in from the back It needs plenty of fresh air to stay cool Do not block the ventilation holes hear thunder even when the amplifier is turned off It s going to rain Get inside quickly Bring the amplifier with you Poor sound Is it loud and distorted Turn down the signal coming from the mixer or signal source Is the input connector plugged completely into the jack Check the speaker connections and verify that all connections are tight and that there are no stray strands of wire shorting across the speaker terminals If possible listen to the signal source with headphones plugged into the console If i
