4. Connection

2-way stereo setup
For using the CCR 24 as a 2-way
stereo crossover, refer to the
following wiring diagram:
Quasi-3-way stereo setup
For using the CCR 24 in a quasi-3-way stereo configuration, the
SUB-BASS output must be used to feed the separate power
amplifier for the bass speakers:
Sub Bass
Amp 3 (Sub)

5. Operation / Setting hints

As both channels 1 and 2 are absolutely identical, the following
instructions refer only to one channel. All control elements on the
CCR 24 are recessed-mounted, allowing for manipulation only
with the help of a small screwdriver or similar tool. This way, the
risk of accidental alteration of the settings is highly reduced.
POWER LED
The unit is turned on by connecting the supplied mains cable to
the power supply. The green POWER LED on the front panel indi-
cates that the unit is connected to the mains power.
X-OVER frequency selector switch
The CCR 24 offers 16 fixed crosso-
ver frequencies, selectable via the
X-OVER hex-code rotary switch:
60 Hz; 80 Hz; 100 Hz; 125 Hz; 150
Hz; 200 Hz; 250 Hz; 300 Hz; 600
Hz; 800 Hz; 1kHz; 1.2kHz; 1.5kHz;
2kHz; 2.5kHz; 3 kHz. Having fixed
frequencies has the advantage of
100% tracking accuracy
between the highpass and lowpass filters.

Lowpass GAIN control
The GAIN control allows for free
adjustment of the lowpass signal
gain from -15 dB to +15 dB.
Lowpass PHASE control
The lowpass PHASE control
potentiometer allows to vary the phase of the lowpass signal from
0 to 180 degrees in reference to the highpass signal. This function
is important to avoid sound de-gradation by cancellation of super-
imposed frequencies which are out of phase.
Highpass GAIN control
The GAIN control allows for free
adjustment of the highpass
signal gain from -15 dB to +15 dB.
Highpass PHASE switch
This switch reverses the highpass signal phase, which means the
same as shifting it by 180 degrees in reference to the lowpass.
This pushbutton-switch is recessed-mounted and requires a small
tool (screwdriver, match etc.) for operation. The yellow REVERSED
LED indicates the inversed highpass phase.
