Observing Correct Speaker Wire Polarity

When you connect speakers to your amplifier, you will notice that one side of the two conductor speaker wire will have some sort of mark: either printing, a raised ridge on the insulation, or a different color of conductor to let you know which wire to connect to the positive and which to the negative speaker terminals so you can repeat the connection on the power amplifier's binding posts.

Configuring the PAL-80, PAL-65, and PAL-45 for Stereo or Monaural Operation

Refer to the Drawing on Page 5

Parasound in-ceiling loudspeakers are two speakers in one: with dual tweeters, dual woofer voice coils, dual crossovers, and separate 8 Ω terminals for both inputs. When using the speaker input assignment switch, you can configure the PAL-80, PAL-65, PAL-45 for three different installation requirements.

Paralleled Stereo Operation, 4 Ω

This is the most typical configuration where each speaker is used to reproduce the left or right channel signal from the amplifier. This usually means that at least two speakers will be used in the room or zone.

1.Connect the output of the appropriate channel of the power amplifier to the speaker terminals on the left side of the crossover PCB.

2.Set the input assignment switch to its “Paralleled Input” position.

3.Repeat steps 1 and 2 for the other speaker which will reproduce another channel.

IMPORTANT NOTE: If you connect the amplifier to the speaker terminals on the right side of the crossover PCB while its switch is in the “Independent Inputs” position, there will be no output.

Monaural Operation, 8 Ω

In this configuration, the left and right amplifier signals are reproduced by the dual speaker elements so you can hear both channels from one speaker. This is useful for a small area such as a bathroom or short hallway where there is no advantage to using two speakers. You can also use this configuration in a large room with multiple speakers where uniform coverage is a higher priority than creating a stereo image.

1.Connect the left channel output of the power amplifier to the speaker terminals on the left side of the crossover PCB.

2.Connect the right channel output of the power amplifier to the speaker terminals on the right side of the crossover PCB.

3.Set the Input assignment switch to the “Independent Inputs” position.

Independent Stereo Operation, 8 Ω

In this configuration, one amplifier channel drives only one woofer voice coil and tweeter. Use this configuration only if you want to reduce the load on the amplifier or if you want to control the high frequency dispersion by selecting the channel corresponding to the direction of only one of the tweeters.

1.Connect the left output of the power amplifier to either pair of speaker terminals.

2.Set the Input assignment switch to the “Independent Input” position.

PAL-45, PAL-65, PAL-80 specifications

Parasound is renowned for its high-quality audio products, and its line of amplifiers, including the PAL-65, PAL-45, and PAL-80, exemplifies this commitment to audio excellence. Each model boasts unique features and advanced technologies that cater to audiophiles and casual listeners alike, ensuring a captivating listening experience.

The Parasound PAL-65 is a powerful amplifier known for its reliable performance and exceptional sound quality. With a power output of 65 watts per channel, it is versatile enough to drive a wide range of speakers. One of its standout features is its Class A/B amplification, which balances power efficiency with audio fidelity. This results in a warmer sound signature while minimizing distortion at higher volumes. The PAL-65 also incorporates a toroidal power transformer, enhancing the amplifier's efficiency and transient response, allowing for crisp audio reproduction even at demanding levels.

Moving on to the PAL-45, this model is designed with a focus on delivering pristine sound at a slightly lower power output of 45 watts per channel. Ideal for smaller rooms or less demanding setups, the PAL-45 still offers many of the same premium features found in its higher-powered siblings. Its discrete output stage ensures high current capability, which translates into a dynamic and engaging listening experience, making it a popular choice for both music and home theater applications. The PAL-45 maintains the same exceptional build quality as the rest of the PAL series, ensuring longevity and reliability.

Finally, the PAL-80 takes performance to new heights with its 80 watts per channel output, making it a powerhouse for larger rooms and more demanding speaker systems. This amplifier is engineered with advanced circuitry to minimize noise and enhance audio clarity. Its bi-directional cooling design aids in heat dissipation, ensuring efficient operation even during extended use. Furthermore, the PAL-80 features multiple input options, including balanced XLR connections, catering to various sources while maintaining audio integrity and minimizing interference.

In summary, the Parasound PAL-65, PAL-45, and PAL-80 amplifiers showcase an impressive blend of power, technology, and build quality. With features designed to enhance the listening experience, each model serves its purpose, whether for casual listening or high-performance audio setups. Parasound continues to uphold its legacy in the audio industry by delivering amplifiers that meet the diverse needs of music enthusiasts and home theater operators.
