A. Notes on Rigging Safety
Please read these instructions carefully before you begin setting up the system!
1.1 Intended Use
Specifications for intended use include the
following:
• When rigging enclosures, make sure that the load
is centered directly under the suspension point on
the rigging frame.
• The rigging frame may be tilted (not to be
confused with curved!) no more than 10% (6°).
Note that the specifications for intended use
require you to read and heed all of the operating
instructions and comply with inspection and
maintenance requirements.
Any use other than specified is unintended. The
manufacturer shall not be liable for damages
resulting from unintended use.
1.2 Unintended Use
Improper use of rigging frames and incorrect
handling of this load-carrying equipment can pose a
serious danger. Never
• use rigging frames to exert diagonal force or
tension on loads,
• use a crane to dislodge stuck or immovable loads,
• lift people,
• strike, knock or dent rigging frames,
• heat-treat or weld rigging frames,
• exceed the truss’s maximum load-carrying
capacity
Note that in addition to the above specifications,
the operational safety regulations of VBG 9
(accident prevention regulations of the German
employers’ liability insurance association) apply.

Electrical and Acoustical Data
The CTA 208 enclosure features two 8" cone chassis
speakers and four 1" B&C high frequency drivers
with a front-mounted acoustical lens in a CD horn
configuration. An internal passive crossover with a
crossover frequency of 2 kHz addresses the drivers
via a special acoustic lens. The CTA 208 enclosure‘s
nominal electrical power-handling is 500 watts
RMS at 8 ohms impedance. It produces 105 dB
(1W@1m) sound pressure, measured under halfspace conditions. Maximum SPL measured under
the same conditions at one meter is 134 dB at 10%
THD. The CTA 208 radiates at a horizontal angle of
100°. Frequency response ranges from 95 Hz to
19 kHz (±3 dB).
Connections
The ports are out of harm‘s way on a recessed
connector panel on the CTA 208‘s back. It offers
two Speakon® NL 4 connectors. Pin assignments
are pin 1+ = mid/high +, 1– = mid/high-.
Caution: Please connect just one CT 208 to each
CTA 118 Sub enclosure. The second port serves to
connect a power amp in parallel (up to two CTA 208
at 4 ohms).
1.1 Specifications, CTA 208
A professional two-way system featuring cylindrical
wave technology, this cabinet serves to set up
vertical line arrays and project a coherent wavefront
across the entire frequency range. The precisiontuned enclosure sports two 8" midrange speakers.
Four 1" high-frequency drivers address two constant
directivity horns with 100° horizontal directivity via
a special acoustic lens. Vertical directivity depends
on the number of CTA 208s in use.
The housing is made of 15/18 mm birch plywood
coated with black PU varnish. Its fully integrated
rigging hardware adjusts to four 0°, 3°,6° and 9°
angles for setting up line arrays. An integrated
pole mount offers two tilt angles of 3° and 11°. An
impact-resistant steel grille covers the front.

ConTour Array™ 1.4
ConTour Array™ rigging hardware consists of the
following parts:
• a rigging frame with two shackles for attaching
motors or chain hoists.
• integrated rigging points on the side and back for
flying ConTour Array™ CTA 208 Mid/High units.
• three quick-release pins per CTA 208 for
connecting the enclosure to the rigging frame.
Important note on pins: Quick-release pins connect
rigging hardware and speaker enclosures, and their
proper function must be tested and verified. Pins
must always engage fully in the (fitted) hole. Under
no circumstances may these pins release on their
own when subjected to tractional forces. The nib in
the center of the pinhead must always be depressed
to insert pins; it releases the ball detents in front.
Once the pin engages in the hole, the nib must ease
back to its initial position.
1.1 Mounting the Rigging Frame
It takes two people to perform these tasks. Remove
the quick-release pins from the enclosure. Set the
rigging frame on the enclosure. First attach the two
front connectors. Turn the rigging frame‘s connector
component down and slide it into the rear
rigging connector.
Insert the rear pin through the hole labeled 0°.
Attach to the rigging frame the shackle that accepts
the motor hook. Your choice of pick point depends
on how sharply you aim to curve the array later.
Note: Depending on application, you may not be
able to select a pick point with a shackle. In this
case, use two shackles and a suitable O-ring as
shown in Figure 9.
Check all pins on the top rigging frame to ensure
they seat firmly. Attach the motor to the shackle.
Important: Ensure the motor‘s chain bag hangs
freely and does not rest on the rigging frame!
Engage the motor to lift the cabinet from the case.
Roll the case off to the side. Remove the two front
pins from the enclosure you wish to mount and fold
down its connector component. Now you can rig
further cabinets.
Tip: If you intend to rig additional enclosures, we
recommend that you attach all the required speaker
cords to the rigging frame now because this task
becomes more difficult as the array grows higher.
Be sure to use cords of sufficient length!
1.2 Setting the DualCurve™ Angle
Curve the two CTA 208 cabinets using the rear
connector component. You have four angles to
choose from, 0°, 3°, 6° and 9°. Remove the pin on
the rear, insert lead the connector into the rigging
track and secure the connector component with the
pin as pictured.
1.3 Rigging Additional
CTA 208 Mid/High Enclosures
Hoist the mounted CTA 208 Mid/High cabinets to a
height that allows you to roll a second case holding
two enclosures under the array. Remove the two
front pins from the enclosure you wish to mount.
Move the second case with two additional CTA 208s
into position. Slowly lower the top two cabinets
until the two front connectors engage. Insert the
two front pins first, ensuring they engage fully and
securely (see Figure 11 a). You may have to shift
the two enclosures slightly to ease the pins into
position. To attach the rear connector component,
you must swivel it out of the track and ensure it
faces down (see Figure 11 b). Insert the pin through
the hole labeled 0°, 3°, 6° or 9° as required.
Hoist the array consisting of four CTA 208
enclosures high enough to remove it fully from the
case. Secure the hoisted array against blasts of wind
or unintentional twisting to prevent it from moving.

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.

2. Ground stacking
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.

Four keys operate the device - Menu, Enter,
Up and Down.
Menu/ Esc:
This key accesses the controller’s menu structure
and exits a menu level.
Enter:
This key confirm changes and access menu levels.
Up and Down:
These keys navigate within a menu level and
increase and decrease displayed values. Please refer
to the menu structure quick guide at the end of the
chapter to learn more.
3.1 Level
You can adjust input levels from – 96 dB to +6 dB in
0.5 dB steps. Use the Up or Down keys to select the
gain setting and confirm your selection with Enter.
Note: The Level parameter adjusts the level after the
analog-to-digital converter to balance out varying
(system) levels. Level does not influence the input
signal’s volume in front of the analog-to-digital
converter. If the display reads “Digital Clip ?! Check
Input !” be sure to reduce the level at the mixing
console. In this case, the signal is saturating the
analog-to-digital converter, distorting the signal’s
rectangular waveform to create square waves. This
sounds extremely annoying and will eventually
destroy the power amp and speakers.
Tip: If you wish to reduce the volume of the lower
mid/high unit in the array – say, because it hangs
low and listeners are close to this unit – you can
use Level to do this. However, Level also affects the
subwoofer’s volume. Increase Sub Level by the same
value to compensate for the difference.
D. The ConTour Array™ DDO-Pro™ Controller
Fig. 16: DDO-Pro™ network
Fig. 17: DDO-Pro™ Controller panel
Net Ports link several CTA 118 Subs in a
communication network. Use CAT 5 network cables
or professional Ethercon cables with a metal plug
to do this. Connect the first CTA 118 Sub’s output to
the next unit’s input, and so forth.
Note: This is purely a data interface. The DDO-Pro™
Net Port does not send audio signals.
If you wish to adjust controller settings (for example,
filter, gain or delay), you can do this on any CTA 118
Sub’s control panel. Automatically, the unit becomes
the master controller and sends parameter changes
to all networked CTA 118 Subs (up to 32 units).
Note: It does not send "Utilities" menu settings.
Caution: If you wish to use another CTA 118 Sub and
a ConTour Series™ cabinet (CT 108, CT 112, CT 115) for
near-fill or in-fill applications alongside CTA 208
speakers in a larger rig, DO NOT network it! Otherwise
the connected CT 108, CT 112 or CT 115 will adopt the
settings entered for the mid/high array.
2. Audio Signal Routing
Use an XLR cord to connect the signal source to
the first CTA 118 Sub’s signal input. If you wish to
connect further CTA 118 Subs to the source, do this
using the Signal Through ports. The XLR port’s pin
assignments are: pin 1 = ground, 2=+, 3=–.
Be sure to read section 3.1 covering maximum input
signal level and digital clip error and heed these
guidelines.

3.2 Key Lock – Preventing
Unauthorized Access
Locking Keys
You can lock the CTA 118 Sub’s keys to prevent
unauthorized or unintentional access. To lock keys,
press the MENU key, use the arrow up and down
keys to select the menu option Keylock (if not
already selected) and press the ENTER key. The LCD
now reads Are you sure? Press the ENTER key again
to lock keys.
Unlocking Keys
To unlock keys, press the MENU key, use the arrow
up and down keys to select the menu option Keylock
(if not already selected), and press the ENTER key.
The LCD now reads Are you sure? Press the ENTER
key again to unlock keys.
3.3 Utilities
Sync Remote
When you confirm the Sync Remote command, the
unit sends the current settings to all networked
controllers. The control panel currently in use is the
master. This feature comes in handy if the network
connection fails.
Noise Reduction
You can activate Noise Reduction on demand. It
mutes signal paths when the rig is off-line. The unit
ships with this feature deactivated.
LCD Contrast
Adjust the display’s contrast to taste using the Up
or Down keys. Confirm your selection with Enter.
Factory Reset
When you confirm this function, ALL settings reset
to their factory defaults. For example, you could use
it to set all delays to 0 ms and levels to 0 dB.
Delay Base
Select the preferred delay display reading - meters
(m), feet (ft) or milliseconds (ms). Select the
option with the Up or Down keys and confirm your
selection with Enter.
3.4 Sub Delay
Sub Delay is a time alignment tool, that is, it
compensates differences in mid/high units’ and
subwoofers’ response times. Like Sub Level, Sub
Delay controls subwoofers’ and mid/high units’
relative delay.
For example, if you place subwoofers well in front
of mid/high units, you must delay the subwoofers
accordingly. Do this by adjusting a positive
delay value in the Sub Delay menu. If you place
subwoofers well behind mid/high units, you must
enter negative values to compensate.
Caution: Negative Sub Delay values delay the signal
path from the subwoofer to the mid/high unit,
causing overall system latency! Experience has
shown that this method compensates differences of
15 ms or 5 m without latency problems. The control
range sweeps from -30 ms to 29.6 ms.
3.5 Delay
Delay controls the overall delay of a system
comprised of subwoofers and mid/high units. The
highest setting is 72.6 ms.
3.6 Sub Level
You can adjust the balance of volumes between the
subwoofer and mid/high unit from -12 dB to + 6 dB
in 0.5 dB steps. Use the Up or Down keys to select
the Sub Level and confirm your selection with Enter.
3.7 System Setup
A special filter preset is available for each
configuration (see fig. 19 a-f). Be sure to assign
the same preset to each DDO-PRO™ controller for
every configuration (1 to 4 CTA 208s). Use the Up
or Down keys to select the right preset and confirm
your selection with Enter.

Regularly check the vents to ensure air flows freely
in and out. Clean the foam rubber filters whenever
necessary. Remove the vent grille on the back to do
this.

Spare Parts
Note:
• If your equipment needs service, please turn
to your HK AUDIO dealer or the HK AUDIO
distributor in your country. They stock the
required spare parts.
• In the event of a defect, always indicate the
defective device’s serial number. This way the
HK AUDIO service team can immediately find out
if an update is available for your product.
• Use only original HK AUDIO replacement speakers
and parts! Most were developed especially for HK
AUDIO products and are not available direct from
speaker manufacturers!
3. Replacing Loudspeakers
and Voice Coils
3.1 1", 8" and 18" Speakers
Proceed as follows to replace the given speaker:
• Unfasten and remove the Phillips screws holding
the grille in place. Remove the grille. These screws
are on the CT 118 Sub’s front panel and the
CTA 208’s side and bottom panels.
• Unfasten and remove the hex head bolts holding
the speaker in place.
• The speaker is now detached. Disconnect the
speaker wires.
Caution: When installing and connecting a
replacement speaker, ensure the polarity is correct!
Red= positive, black = negative
1. Maintenance
3.2 The Drivers’ Voice Coils
Proceed as follows to replace the drivers’ voice coils:
• Remove the front grille as described above.
• Unfasten the four screws holding the horn yoke
and remove the horn and driver from the baffle.
Disconnect the wires connecting the driver. Ensure
correct polarity when installing and connecting
a replacement speaker! Red= positive, black =
negative
• Unfasten the voice coil housing’s hex head bolts
using a 3 mm wrench.
• Take the lid off the voice coil housing.
• Replace the voice coil.
Important note: Replace the voice coil in a clean
working environment only. Be sure to keep dust
and dirt out of the open driver. If despite your
precautions particles manage to get in, use a strip
of adhesive tape to remove them or carefully blow
compressed air into the back of the driver to whisk
the particles out. When installing the new voice
coil, ensure it is centered properly. Proceed as
follows to check this:
Close the cover of the voice coil housing and
reconnect the cords (red = positive, black =
negative). Feed a sine wave signal with a frequency
between 1000 Hz and 1500 Hz into the mid/high
enclosure’s input. Sweep through the frequency.
If you hear abrasive noises like crackling or
scratching, the voice coil is not centered properly.
Reopen the voice coil chassis and turn the voice coil
a bit until it renders the signal cleanly!
4. Checking Speakers’ Phase
As a precaution, always check the components’
phase using a suitable phase-checker after replacing
speakers. To do this, connect the CTA 208 mid/high
unit to the CTA 118 Sub using a Speakon® cord.
Note: If you are checking the CTA 208 mid/high
unit in passive mode with an external power amp,
you will get a different phase reading! Therefore
always use the CTA 118 Sub for phase checks.
Connect the phase-checker to the CTA 118’s signal
input. It may be advisable to lower the input level on
the DDO-Pro™ Controller!
The speakers’ phases should read as follows:
With CTA 118 Sub:
18" woofer: In phase (+)
8" speaker: Out of phase (-)
1" driver: In phase (+)
CTA 208 passive:
8" speaker: In phase (+)
1" driver: Out of phase (-)
