SWR WorkingPro 2x10C Instrucciones De Funcionamiento página 10

Before changing your speaker setup, a basic
knowledge of impedance ratings is essential to
the quality of your sound and the safe opera-
tion of your equipment.
The general rule is: if you connect a speaker
load with a total impedance that's equal to the
minimum impedance rating of your amplifier,
you'll be OK—as long as the speakers are rated
to handle the power output from your ampli-
fier.
The illustration shows the impedance totals of
different speaker combinations. NOTE: All SWR®
bass speaker enclosures, as well as most others,
are wired "in parallel" (not series), therefore, this
section applies to parallel speaker connections
only.
All speakers in a group should have the same
impedance so that each speaker will receive the same amount
of power from your amplifier. If impedances are different, the

speakers with lower impedances will be much louder than
the rest. For example, with an 8–ohm speaker and a
16–ohm speaker both connected to your amplifier, the
8–ohm speaker will be twice as loud (and get twice the
power) as the 16–ohm speaker. Calculating total power
handling capacity and positioning speakers of different
impedances becomes complicated!
Δ CAUTION!—Operating with a speaker load below
the minimum impedance rating of your amplifier
can easily overheat the amplifier and cause dam-
age. Operating above the minimum impedance
rating will reduce the amplifier's maximum power
output potential.

power rating issues go to the SWR Website at
