. CROSSOVER SETTINGS

5.1 SELECTING THE OPERATION MODE
The R680N is multi-channel concept amplifier with integra-
ted active crossovers and thus, offers different amplification
modes which can be set by the operation mode slide switches.
Three of these switches can be found on the R680N amp. T hese
switches enable you to configure each stereo channel pair to
work in either in fullrange, highpass or even bandpass mode.
Therefore - before you get started with the settings of crosso-
ver 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. T his will make sure that every
speaker system is only working in its proper frequency operation
range, for which the speaker was designed. For example select
HIGHPASS, if the speaker is a component- or coaxial type, or
BANDPASS in case of a kickbass or subwoofer system - and
finally FULL(range) if the passband frequency of the stereo
channel is already controlled by a head-unit with an integrated
DSP based active crossover.
5.3.1 HIGHPASS FOR COMPONENT AND
COAXIAL SPEAKERS
Before you start your adjustments, all tone controls (i.e. Bass,
Treble), fader/balance and loudness featured on the head unit,
must be set to their respective neutral or center position.
Please take a look at the chart below, featuring the suggested
high-pass cross-over frequency settings for coaxial- and com-
ponent speaker systems - and adjust the highpass control of
each channel pair that drives satellites speaker systems accor-
dingly. T he most important factor for the individual adjustment
of the highpass crossover frequency is the reproduction of
mid-bass frequencies and the resulting power-handling of the
speaker system. T his setting is always a compromise. T ry to find
a highpass crossover point, that will suit your personal listening
preferences and - at the same time - also considers the physical
(cone excursion) capabilities of your speakers best.
