This would depend on if you are using 4,8,16 ohm speakers or a 70v system.

For regular speakers the (-) wire would go to the COM terminal
the (+) would go to either the 4,8 or 16 ohm terminal (Check on the speaker itself for the "impedance").

If more then one speaker is used then there is some other math involved, but i can help with that.

The 70V terminal is used when powering a bunch of celing speakers like in stores and malls. Each speaker has its own transformer on it, all the transformers are connected togeather in a chain and wired to the COM and 70V terminals.

Playing bar chord at A 5th fret fine move to 7th fret amp gets loud and pops. normal gain at 3 to 4 volume dwn wont do it


Sorry I remember now this is a solid state amplifier,
try electronics spray contact cleaner in the pots of the amp, you will need to unplug and remove the chassis of the amp to do this, there are little notches on the pots, that's where you want to spray, and work the nob back and forth completely, do this to all volume, treb, bass, etc... I know this will fix your problem because I have done this about 100 times servicing amplifiers, the way a solid state circuit works if the pots are dirty the circuit doesn't complete properly causing volume issues, really hope this helps?

Output and power transformers specs


What??? There is NO output transformer for the Mg50DFX. The outputs are direct driven from hybrid stick TDA type solid state amp chips.

The power transformet is probably about 100 watt size and supplies two voltages... one that feeds a +/- 15 volt three terminal regulators... Probably 22 volts +/- to the regualtors and the other supply will be unregulated to the power amp chips.

Realistic MPA-35 amp by Radio Shack


It's not that this amp isn't like "newer amps" with + and - terminals, it's that this amp is made for public-address system use. This kind of amp is used in a store, for instance, to pump background music through speakers all over the place. The terminals you connect to are determined by total impedance of the speaker configuration used.

Most single speakers, or the two- or three-way cabinets for home stereo systems, are 8 ohms. If you're connecting a single speaker you use the "common" and "8 ohm" terminals on the rear panel. With multiple speakers, you need to figure out the total impedance and use the appropriate terminal. In series, impedances add. Two 8 ohm speakers in series would total 16 ohms, so you use the common and 16 ohm terminals. In parallel, the total impedance drops. Two 8 ohm speakers in parallel total only 4 ohms. You need to figure the total impedance of the speaker configuration and connect accordingly. Too great of a mismatch will damage the amp or speakers or both.

You might be able to find the manual for this amp on Radio Shack's website. Here's a link to the manual for the model MPA-40 which should have similar output terminals. The basic information about figuring out total impedance and general use of PA amps applies to your amp as well.

Fender Stage 100 dsp, solid state amp volume (or power) problem


The Deluxe may have more efficient speakers....which would cause it to sound louder. Also, the EQ settings could play a part in this. If the EQ's aren't set the same there could be a noticeable difference in sound.....usually the mids can have quite an effect on overall amp volume....

Pb2600 car amp


It might, at say...6000% distortion. For a true amp power rating look for the RMS per channel specs. This is a much more realistic rating of what the amp can actually put out continuously...
