Functional Description
The RPX-2300 is a stereo 2-way/mono 3-way active crossover for bi-amplified sound systems. The
Linkwitz-Riley filters with adjustable crossover frequencies offer a constant summed amplitude
response and are complemented by 25Hz Low Cut Filters for the inputs, as well as a Mute function
and Phase reverse for all outputs. An additional subwoofer output with separate crossover frequency
control makes this unit effectively a 3-way crossover if required.

AC inlet and fuse holder. Use the supplied AC cord to connect the unit to AC mains. Make sure
voltage and frequency stated and set on the unit comply with your local AC supply. The fuse
can be accessed by the small drawer at the AC inlet. To change the fuse, unplug the AC cord
first, pull out the fuse drawer and replace the fuse ONLY with a fuse of SAME voltage and
rating. If the fuse blows again after replacement, hand over the unit to qualified service person-
nel.
MODE SWITCH. This switch determines whether the unit works in 2-way stereo mode or in
3-way mono mode. Please note that depending on the position of this switch, the functional
assigment of front-panel controls and rear-panel connections might change. For the front
panel control funtion assignment, the ACTIVE CONTROL LEDs (8) indicate the setting and func-
tional assigment. On the rear panel, please see the functional indication printed on the panel.
NOTE:
Do NOT change this switch setting when the sound system is switched on.
INPUT connector (channel A and B). These are mono inputs via balanced XLR jacks.
FREQUENCY RANGE switch. This switch determines whether the front-panel rotary frequency
control (11) works either in the 44 to 930 Hz or 440 Hz to 9.3 kHz range.
LOW OUTPUT connector (channel A and B). These are the balanced XLR connectors for the
low frequency band output signal.
HIGH OUTPUT connector (channel A and B). These are the balanced XLR connectors for the
high frequency band output signal in stereo 2-way mode. The assigment changes depending
on the setting of the MODE switch (2).
SUBWOOFER OUTPUT connector. This is a the balanced XLR output for the mono subwoofer
signal. The cut-off frequency is determined by the front-panel frequency control (16) and the
level set by the front-panel control (17).
ACTIVE CONTROLS indicator. This row of LEDs illustrates the functional assignment of the
front panel elements depending on the setting of the MODE switch (2).
INPUT GAIN control (channel A and B). This sets the main input gain with a ±12dB range. The
presence of a signal and a possible clipping of the input are indicated by the LEDs on top of the
control. The CLIP LED shall only light up occasionally at the signal peaks.
LOW CUT switch (channels A and B). This switch activates the 25 Hz high-pass filter with a 12
dB/Octave slope for protection against infrasonic signals.
LOW/HIGH XOVER FREQUENCY control (channel A and B). This control sets the crossover
frequency between the low and high frequency bands. Depending on the setting of the MODE
switch, the assignmnent changes in 3-way mono mode, where the control in channel A serves
as the Low/Mid and the control in channel B as the Mid/High crossover frequency setting.
OUTPUT LEVEL control (channel A, B and S). These controls allow to adjust the output level for
the high/low frequency band and the subwoofer individually with a ±6dB range. Depending on
the setting of the MODE switch, the assignmnent changes in 3-way mono mode, where the
HIGH level control in channel A is disabled; the LOW level control in channel B serves as the
MID level control, and the HIGH level control in channel B as the HIGH level control.
