5. CROSSOVER SETTINGS

5.1 SELECTING THE OPERATION MODE
The RI-450-200 is a multi-channel concept amplifier with inte-
grated active crossovers and thus, offers different amplification
modes which can be set by the operation mode slide switches.
Two of these switches can be found on the RI-450-200 amp.
These switches enable you to configure each stereo channel
pair to work in either in fullrange, highpass or even lowpass
mode. Therefore - before you get started with the settings of
crossover frequencies and input gain adjustments - you must
select the appropriate operation mode for each channel pair of
your RODEK amplifier, depending on the speaker system that
is connected and driven by the amp. This will make sure that
every speaker system is only working in its proper frequen-
cy operation range, for which the speaker was designed. For
example select HIGHPASS, if the speaker is a component- or
coaxial type, or lowpass in case of a subwoofer system - and
finally FULL(range) if the pass band frequency of the stereo
channel is already controlled by a head-unit with an integrated
DSP based active crossover.
