ADVANCED APPLICATION – LARGE AREA, MULTIPLE SPEAKER SYSTEMS
Large areas such as gathering rooms or banquet halls may require more than a single pair of speakers. Multiple speakers can be connected to the same amplifier channel. This application requires careful understanding of the amplifiers capabilities.
1)Determine what the minimum speaker impedance the amplifier can handle. This should be noted on the amplifier or the amplifier’s instruction manual. Typically, most amplifiers can had a minimum of
2)The XA and XB series speakers are
3)The XA and XB series speakers provide a third wiring post for this type of application. Remove the yellow plastic cap to expose the “+8” wiring post. Using the “+8” wiring post will make the XA and XB series speaker
The figure above shows multiple speakers connected to a single output amplifier channel by using FIM (flexible impedance matching). To make sure the impedance matches the amplifiers minimum 4- ohm specification, the “+8” post is used. The yellow cap that was once on the “+8” post is moved to the “+6” post as an added precaution.
Note: A
Be sure to verify the amplifiers minimum impedance capability.
