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 channel-channel crosstalk.

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.

5125 specifications

The Parasound 5125 is a highly regarded power amplifier designed for both critical listening and home theater applications. Renowned for its performance, the Parasound 5125 combines advanced technologies and user-friendly features, making it an attractive choice for audiophiles and casual listeners alike.

One of the standout attributes of the Parasound 5125 is its robust power output. It delivers 125 watts per channel into 8 ohms and 200 watts into 4 ohms, providing ample power for driving a wide variety of speakers, from bookshelf models to larger floor-standing designs. This level of power ensures that the amplifier can comfortably handle dynamic peaks found in music and film soundtracks, producing clear and impactful audio without distortion.

The Parasound 5125 incorporates the renowned patented "Halo" technology, which is designed to minimize distortion while maximizing sound quality. This technology includes a high-current design that allows the amplifier to maintain a tight grip on the speaker, thus delivering precise control over transients. This results in greater sonic detail, lifelike imaging, and an overall more engaging listening experience.

Additionally, the amplifier features a fully balanced input design that helps to reduce noise interference, delivering a cleaner and more accurate signal to the output stage. This balanced input is complemented by gold-plated RCA inputs, offering versatility in connectivity options. The robust construction of the Parasound 5125 includes a heavy-duty chassis, which helps in minimizing vibrations that can negatively impact audio performance.

Another notable characteristic is the efficient thermal management system in the Parasound 5125. It utilizes a low-noise fan that activates only when necessary, maintaining optimal operating temperatures while remaining discreet in terms of noise production. This feature allows the amplifier to operate continuously without overheating, ensuring reliability during extended listening sessions.

In terms of aesthetics, the Parasound 5125 boasts a sleek and modern design, characterized by its elegant front panel and blue LED indicators. It's not only built for performance but also harmonizes well with contemporary home theater setups.

Overall, the Parasound 5125 stands out for its combination of powerful output, innovative technology, and solid build quality. It is designed to deliver exceptional audio performance, making it an ideal choice for anyone looking to enhance their audio system with a reliable and high-performing power amplifier.
