Make sure that the selected mains voltage of the Crossover is according to the
mains voltage of your region.
Make sure that the mains switch on the rear of the Crossover is set to O
(O=O/On=I).
The standby switch on the front panel has to be set to
(standby).
Connect the supplied power cord to the Crossover and an appropriate mains
socket outlet.
If the supplied power cord does not match your mains socket outlet, please contact your dealer.
Turn o all devices you wish to connect to the Crossover.
With the RCA button on the rear you select the RCA input. If pressed, the RCA
input is active, otherwise the XLR input is used. Connect the outputs of your
preamplier to the inputs of the Crossover. Please use appropriate audio cables
(XLR, RCA).
Audio cables not included in the scope of delivery.
Connect the input of your subwoofer power amplier(s) to the LOW Output of
the Crossover.
You can connect a stereo, two mono or one mono power amplier to the Crossover. In case of a mono subwoofer
application, switch the LOW Mono/Stereo Switch to Mono – both LOW Outputs L and R feed the mono signal.
Audio cables not included in the scope of delivery.
Connect the input of your main power amplier(s) to the MID-HI Output of the
Crossover.
Audio cables not included in the scope of delivery.
If you own an SPL device supporting AMP CTL output(s) you can trigger standby
and operation. Therefore connect the AMP CTL output of the SPL device with a
mono mini jack cable to the AMP CTL input of the Crossover.
The Standby switch has to be set to ON in order to control the Crossover Standby via AMP CTL.
Mono mini jack cable not included in the scope of delivery.
You may also use other V trigger controller. The Crossover is in operation
mode when a switching voltage of Volt DC is applied to the AMP/CTL input.
As soon as the Volt DC is removed, the Crossover switches back to standby mode.
Use a mono mini jack cable where the tip is plus and the sleeve is minus.

If you own SPL Performer power ampliers or other ampliers using V trigger
inputs you can connect the AMPCTL outputs of the Crossover with mono mini
jack cables to the AMP CTL of the ampsto trigger on and standby.
Up to ampliers can be triggered together.
Mono mini jack cable not included in the scope of delivery.
Power up
Turn down the volume of the connected devices.
Switch on mains switch on the back of the Crossover (On = I).
The right VU Meter is dimly lit red.
Operation
Switch the Crossover from standby into operation by setting the standby switch
to ON.
Both VU Meters now lights up brightly.
Standby
Switch the Crossover into standby by setting the standby switch to
( = Standby).
If the Crossover is connected via AMP CTL input with an SPL device supporting
AMP CTL output(s), the Crossover is triggered between standby and operation
together with the SPL device.
The Standby Switch has to be set to ON in order to control the Crossover Standby via AMP CTL.
Power down
Turn down the volume of the connected devices.
Switch o mains switch on the rear of the Crossover (O = O).
The VU Meters no longer lights up.

LOW Section Setup
Choose the LOW crossover frequency (Linkwitz Riley low pass lter) with the
LOW X-OVER switch: , , , , or Hz. The roll-o is dB/octave.
Use the PHASE switch and the PHASE control to shi the LOW signal phase from
-° to +° for phase aligning subwoofer and main speaker positions.
If you switch the LOW Mono/Stereo Switch to Mono – both LOW Outputs L and
R feed a LOW mono signal.
The output level of the subwoofer can be varied from -dB to +dB with the
LOW Level control.
MID-HI Section Setup
Choose a MID-HI crossover frequency (Linkwitz Riley high pass lter) with the
MID-HI X-OVER switch: , , , , or Hz.
Select the roll-o with the ROLL-OFF Switch: or dB/octave.
Normally the crossover frequency is equal to the LOW setting.
The MID-HI crossover can be disabled with the MID-HI X-OVER On/O switch in
case the top speakers shall operate full range.
Basic Controls
The Crossover is equiped with a Hz low cut lter. If on (Hz) the input signal
is ltered below Hz by dB/octave for both frequency ranges – LOW and
MID-HI.
With the VU meter sensitivity switch you can lower the displayed VU levels by
or dB in case you are running hot signal levels.
You can select the VU meter source: the LOW frequency range, the MID-HI
frequency range or the input signal.
