ConTour Array™ 1.4
Depending on application, use two or three
ConTour Array™ subwoofers as the stack‘s base.
Set the desired number of subwoofers on top of
one another.
Caution:
Secure the ground stack to prevent it from tipping!
Use the M10 bushings on the back of the CTA 118
subwoofer and the ground-stack connectors to do
this.
Mount mid/high units individually, one after
another, on the top CTA 118 Sub. Use the ConTour
Array™ stack plate as the base and connector to
the subwoofer. Attach it to the CTA 118 Sub’s pole
mount using the M20 thumb screw. The stack plate
lets you easily adjust mid/high units without having
to move the subwoofer. On this stack plate, you can
freely select the desired down-tilt between 0° and 9°
in 1.5° increments.

3. Mains and Generator
Power Supply
Connect no more than two CTA 118 Subs to one
mains phase (16 A). If you use the Powercon
Link port, connect no more than one further CTA 118
Sub. The 13 A limit on maximum input current
(see label) applies to Great Britain because UK
power cables are approved to 13 A only. 16 A
current is permissible in other countries using EU
power cables.
Caution: If you must power the CTA 118 Sub with
a generator, ensure the generator is running before
you switch the system on. Never switch systems
off and on with the help of the generator! This
can damage the PWM power amps’ switching
power supply!
Note: The Powercon Link is not available for
100-120-volt units.
