Installing The Speakers - Boston Acoustics PRi665 Manual Del Usuario

Connecting three speakers to an amplifier channel is generally not recommended. But if it is done it should be
done using a combined series/parallel connection. Two examples of this type of connection are shown below.
The example on the left shows two speaker in series with the third connected in parallel to one of them. The
third speaker could be connected to either of the speakers connected in series. It could also be connected to
main "+" and "–" terminals instead of the "LOOP" connectors. The example on the right shows two speakers in
series with the third connected in parallel at the amplifier terminals - a variation on the "home run" connection.
The connection methods are electrically the same and produce an impedance of about 1 ohms.
For any system installation more complicated than this you should consult a professional installer for advice on
appropriate equipment, and to be sure the system is connected for best performance and reliability.

Installing the Speakers

Once the installation location has been prepared and the speaker has been connected, the installation of the speak-
er is easy. Simply lift the speaker into the installation hole. Use a phillips screw driver to pivot the mounting clamp
arm outward and draw them down against the back of the mounting surface. Then gradually tighten the mounting
clamp screws, alternating among them, until the speaker is firmly clamped in place. Do not use excessive force when
tightening the mounting clamp screws. Then press the speaker grilles into place to complete the installation.
Listening Levels and Power Handling
The listed power recommendations assume you will operate your system in a way that will not produce distortion.
Even very rugged speakers can be damaged by a relatively low power amplifier if it is producing distortion.
If you hear a harsh, gritty noise, turn down the volume. Prolonged or repeated operation of your speaker with a
distorted signal from the amplifier can cause damage that is not covered by the warranty.
