Parasound PAL-80 Observing Correct Speaker Wire Polarity, Paralleled Stereo Operation, 4 Ω

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.
