How to hook speakers up to a realistic mpa-40


The MPA-40 is a mono public address amp. So it has one speaker output. You select the appropriate socket to suite the speaker type. The 4/8/16 Ohm outs are for various tpyes of Hi-Fi speaker. The 70 Volt is used for muzak in shopping centres, restaurants, and waiting rooms.

If you have a pair of 8 ohm Hi-Fi speakers, you can diasy chain the connections and then use the Com and the 16 Ohm connection.

Daisy chain means you take the wires from a pair of speakers. Connect together the wires going to red on one speaker and black on the other. This now leaves you with two wires going to the other red and black terminals on the speakers, but the ends in your hand are not connected to anything yet. Plug the black in to COM. Plug the red in to 16 Ohm.

The sound from the speakers won't be stereo. It will be mono because that's all the amp outputs. But both speakers will work so long as they're functioning units.

If you have two 4 Ohm home theater speakers then you can do the same trick. 4 + 4 makes an 8 Ohm load. Connect the red to the 8 Ohm output.

Don't be tempted to try to connect to multiple terminals. The amp isn't powerful enough to to run more that one speaker chain.

Hope this helps

Looking for service manual for realistic MPA 80 MODEL 32-2026


If it's on both channels the hum could well be produced by the main power supply capacitors. The big ones. Replace all!

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.

Jamo MPA-101 2 channel amp quit working


Check the small electrolytics on the power supply board for high ESR, Very common problem on these amps. Protect circuit stays latched due to high ripple from PS.
