It also assures the best results when you’re listening to pure stereo.
•If the 5125 is more powerful than the two channel amplifier, we recommend the preceding 5.1 channel connections for the 5125. Use the two channel amplifier for the surround back channels.
For example, if your two channel amplifier is the Parasound Model 275 rated at 75 watts/ channel, use the 275 for the surround back channels and your 5125 for the other five channels.
•If the two channel amplifier is of high quality, with at least the same power rating as the 5125, we recommend that you use the two channel amplifier for the front left and right channels, and the following connections for the 5125.
For example, you might prefer a Parasound Model 2125 to drive your left and right speakers, and use your 5125 for the other five channels. Even with the same 125w/channel power rating, the 2125 has a performance edge over the 5125, with superior channel separation and lower

Note: If you elect this connection arrangement you will probably need to use the Auto Turn On
12V option because none of these channels supplies adequate levels for the 5125’s Audio sensing.
Each – and + speaker terminal will accept bare speaker wire up to AWG 12, a wire terminated with a 1⁄4” spade lug, or with a single banana plug; dual banana plugs which are 3⁄4” (19mm) apart may be used for each speaker.
If you use bare wires, remove only enough insulation, about 1⁄2” (12mm) for each exposed bare wire to insert through the small hole in the side of the binding post. Before inserting a bare wire, twist the strands tightly between your fingers to prevent strays that might touch the chas- sis or another terminal and cause a short circuit. If you have soldering experience you may want to “tin” the stripped bare wire with solder for a cleaner termination and to prevent the wire from oxidizing.
Correct Speaker Polarity is Important
As you connect the speaker wires, you can see that the insulation on one of the two wires in each pair has either printing or a raised ridge. The marking lets you know which wire you con- nected to the positive speaker terminal at its other end.
Make sure the + wire you attach to each Model 5125 + speaker terminal is attached to the + terminal of the speaker for that channel.
