70V/100V/8 Ohm Settings
There are several jumpers on the Amplifier
Boards that are used to configure the amplifiers for
use with a 70V distributed system, a 100V
distributed system, or an 8-ohm load.
The SP2400 is shipped with the jumpers set for
70 Volt operation in U.S. versions, and 100 Volt
operation in European versions. You will need to
change these jumpers only if you require a different
configuration than the default settings. Refer to the
following illustration for the locations of the jumpers.
Note: Each amplifier board must be configured
separately.
