Transportation & care
Transportation
Prior to transportation, always remove all
cables from the cabinets. During transpor-
tation, protect the cabinets against slipping
or falling over. If necessary, secure the
cabinets with fastening straps or similar
devices.
Environmental conditions
Do not expose the cabinets to rain, snow or
other sources of humidity. If used outdoors,
protect the cabinets appropriately.
Placement of cabinets
Supporting surface
The cabinets must only be placed on level
and firm surfaces or on highstands. The
handles on the cabinets are only intended
for transportation and must not be used for
Riggging. If subwoofers are used as a support
for the cabinets, an additional security device
(e.g. strap or rope) must be provided to
prevent the upper cabinets from 'crawling'
off the subwoofer due to vibrations.
Positioning
To allow the sound to propagate freely and
reach all listeners, the cabinets should always
be placed clear above the audience.
The Club series cabinets are capable of
producing high sound levels. To prevent
hearing damage, do not place the cabinets
too close to the listeners.
Connection of cabinets
Impedances
When one or more cabinets are connected to
an amplifier output, the total load that the
amplifier output 'sees‘ must always be
observed. In order to make use of the full
output power potential of the amplifier, the
connected total impedance per channel
should be equal to the lowest allowed load
value for the amplifier.
If, for example, the lowest allowed load
impedance for an amplifier is 4 ohms, a total
load of 4 ohms will yield the highest possible
output power without overloading it.
When more cabinets with identical impe-
dances are connected to an amplifier output,
the total load that this output 'sees' can be
calculated using the following formula:
cabinet impedance
total load =
amount of cabinets
As an example, two cabinets with each
8 ohms impedance exhibit a total load of
4 ohms to the amplifier output.
As all Club series speakers have 8 ohms
impedance (with the exception of CD 212.1,
which has 4 ohms) and most amplifiers can
handle loads down to 4 ohms, connecting
two Club series speakers to each amplifier
channel will increase the total system power.
