3. Important safety instructions
1. Read this manual
2. Heed all safety warnings
3. Follow all instructions
4. The user should never incorporate equipment or accessories not approved by Ohm
5. Safety warnings
Sound systems are capable of producing high sound pressure levels which can lead to a
hearing damage especially in long term exposition.
To prevent damage to hearing avoid being too close to speakers in operation.
The generally accepted standard to minimize hearing risk is based on an exposure to
85 dBA for a maximum limit of eight hours per day, followed by at least ten hours of recovery
time at 70 dBA or lower (at which the risk of harm to healthy ears is negligible). Then
a “3 dB exchange rate” formula is applied, which means that for every 3 dB above 85 dBA,
the maximum exposure time is cut in half.
Noise levels above 140 dB are not considered safe for any period of time, however brief. For
children, the World Health Organization recommends no exposure above 120 dB.

CT-10, CT-12 and CT-15 loudspeakers are fitted with threaded mounting holes, suitable for attaching
flying hardware or a wall-mount bracket. The details of the mounting points are shown in the
drawings. (pages 13, 15, 17)
5.1 Wiring
Ensure that all possible installations connections comply with the applicable safety guidelines
and that the size and strength of cables are sufficient. Ensure that all connections are secured
against coming loose.
Never use signal cables or power cords for suspending, aligning or securing the system.
Never use signal cables or power cords that are frayed.
To prevent the risk of electric shock, do not connect the loudspeaker with the amplifier switched
on.
CT-10, CT-12 and CT-15
These speakers are equipped with two parallel-wired Speakon connectors,
connected 1+/1- & 2+/2-
To avoid loss of power, the cables should have a minimum wire gauge of 2 x 4 mm2and more for
long distances. Ohm recommends using 2 x6 mm2cable and high quality Speakon connectors.
5. Installation
Installation should only be carried out by experienced technicians.
Before any installation indoors or outdoors ensure all risk assessments required are carried out.
Any technicians responsible for assembling, safe set up and use of the sound system on site must
be aware of all risk assessments.
Falling speakers can be FATAL. Always ensure that adequate attention is given to safe installation
especially when external forces could have a bearing on the stability of the speakers.
Before setup ensure every possible eventuality is addressed in order to prevent the system from
becoming unstable, i.e: uneven ground, weather conditions, unstable fixing points or people
knocking against the system.
Remember that speakers can also move as a result of vibrations.
Consult a professional rigger or structural engineer prior to suspending loudspeakers. Always
check the safe working load limit of the structure supporting any loudspeaker. Make sure that the
rigging hardware is adequately rated to handle the actual load in accordance with current health
and safety guidelines.
Avoid installing loudspeakers in places exposed to harsh weather conditions.

Verify that the polarity of the connections to all of your loudspeakers are correct. When more
than one loudspeaker reproduces the same frequencies, but with opposite polarity, there will be
sound cancellations. Therefore, if any of the loudspeakers are wired so that the +/- connection
polarity is reversed with respect to the others, incorrect reproduction will result. Most notably,
the bass response will suffer. This is especially true when loudspeakers are situated in adjacent
positions where the sound waves readily interact with each other.
Two cabinets can be connected in parallel, at which time the signal can be linked through from
one loudspeaker to the next. Make sure that the linked cabinets total impedance is more than the
minimum impedance indicated on the amplifier.
Systems total impedance can be calculated with the following formula:
6.1 Amplification
There is no exact answer to the question of what amplifier size you should use for a loudspeaker.
The loudspeaker power rating in Ohm’s specifications only means it has passed a standard power
test. This provides a rating that can be used as a point of comparison with other loudspeakers.
This rating does not necessarily correspond to the best amplifier size to use nor is it a measure
of a “safe” amplifier size to use. Rather, the amplifier should be sized according to both the sound
levels required and the type of audio signals that will be reproduced. If you are unsure of how to
determine this, consult with a qualified professional or contact Ohm Technical Support.
Preventing damage to the loudspeaker is a function of operating your audio system so that the
loudspeaker is not stressed beyond its design limits.
6. OPERATION
1
1/imp 1st cabinet + 1/imp 2nd cabinet + 1/imp nth cabinet
Normally systems minimum impedance should not be lower than 2 ohms, with Ohm D class
amplifiers not lower than 4 ohms.

6.2 Signal Processing
External processing is often needed, for example, to accommodate particular program material,
less than optimum acoustics, feedback control, or personal taste. Processing units are also be
used to set the delays and crossover between cabinets.
CT-10, CT-12 and CT-15 Phase and impedance corrected crossover networks are designed for high
power applications and the mandatory use of external EQ provides unrivalled tonal balance and
transient response.
All the latest Ohm signal processors can be accessed by the Ohm Spyder software which is
available for download on the Ohm website. www.ohm.co.uk/ohm_downloads.htm. Please check
back regularly to ensure you have the latest version. (Always ensure that your current settings
are backed up before installing new versions of the software to avoid deleting settings). Read the
manual for Spyder Software for further information.
6.3 Protecting the Speakers
In general, audio signals should not be over driven. If an Ohm power amplifier is overloaded at
the output stage(clipping), the amplifier will activate a clipping warning signal. The signal must
be reduced as soon as it sounds distorted. The Ohm warranty does not cover the damage to the
speaker/s or consequential damage caused by overloading the system.
6.4 Ground loop
If the cabinet makes a loud humming or buzzing noise after the speaker has been connected,
check that there is no ground loop in the system. Some amplifiers and system controllers have
a ground lift switch. Try to set these switches to the “lift” position one after the other to get rid
of the problem. Always use a “clean” power supply for the sound, meaning that the same power
supply does not run, for example, the lighting system, which may cause interference to the sound.
It is also possible that the ground loop is before the amplifications (in mixing desk, effects or
equalizers) so all other sources need to be checked if it continues.
Never try to get rid of the ground loop by disconnecting the protective earth contact at the mains
connector! This is extremely dangerous!
Use only high-quality audio connectors and cables and if possible only balanced outputs.

7. Service and Maintenance
If for any reason your Ohm product fails, contact the Ohm Technical Support (support@
ohm.co.uk) or your local dealer (check the Ohm website), this applies to both warranty and
non-warranty faults.
Faulty rigging parts can potentially cause serious consequences and liabilities, so for any rigging
hardware problems contact Ohm to determine the appropriate service solutions.
The metal components of the cradles and stacking systems are covered by a textured powder
coating which will protect them against short term moisture. All the cabinets and rigging parts
should always be stored, transported and used under dry conditions. CT-10, CT-12 and CT-15 are
not designed for long-term outdoor use.
7.1 Performance Testing and Periodic Inspection
Complete inspection of the enclosure and a listening test and formal measurements should be
done periodically. The interval between such tests will depend on system usage and the conditions
of use, but make sure these inspections are made at least yearly. All the transducers should be
tested regularly to make sure they work as intended. A sine wave sweep at approximately 10% of
rated power will usually reveal possible transducers and enclosure problems, faults usually cause
some distortion, buzzes or rattles.
Faults in internal components and wiring usually cause transducers to stop working or to be
intermittent. Only trained technicians may inspect and fix the connection problems.
Take extra care when inspecting all the rigging hardware. Visually inspect all rigging parts each
time they are used to detect all possible conditions that may affect load handling capability (i.e.
wear, deformation, cracks, corrosion).
7.2 Cleaning and Cosmetic Repairs
If the exterior surface requires cleaning, use a damp cloth to remove any dust and dirt and use a
dry cloth to finish the cleaning. Do not use any cleaning solvents or abrasives.
All the CT range cabinets are painted with a high quality paint. Enclosures that are designed
for road-use, may over time show signs of wear and tear during normal use, for paint touch up,
contact Ohm or your dealer for re-painting or to purchase the touch up paint and instructions for
its application. Before paint touch up, fix any cosmetically damaged wood parts using common
woodwork methods and materials.
