MULTI-SPEAKER INSTALLATION CONSIDERATIONS
■
■
To ensure optimal operation of your amplifier or receiver,
you must show it a load that it can handle safely.
This generally requires the use of impedance matching
devices when connecting multiple speaker pairs
■
■
Calculate the impedance matching settings
(refer to the table below as a guide)
■
■
Total speaker wattage must be within the amplifier’s
power output capacity
■
■
Always double check settings and test impedance is
correct before connecting to your amplifier
When installing multiple speakers to an amplifier output, it’s important to consider the following:
