Installation guide
This chapter deals with the practical aspects of
installing the Intellivox loudspeaker column.
•
SI units are used as a default, all mentioned
dimensions are stated in meters or millimeters.
•
Unless stated otherwise, column dimensions refer to
the standard Intellivox-2c, which has the electronics
module mounted at the low end of the enclosure.
Dimensions of other Intellivox models can be taken
from the appropriate datasheet.
2.1 Items in the box.
The following items are shipped with each Intellivox
column:
Table 1 List of shipped items.
•
The mounting brackets as well as the connector set
are packed in one of the top end boxes of the main
packaging.
2.2 General considerations.
As already mentioned, mounting height and position
are important parameters in relation to the acoustical
performance of the system. Unless specified otherwise
by the sound system designer, the Intellivox column
should be mounted in a position exactly perpendicular
to the listening plane. Contrary to a conventional ‘low
Q’ loudspeaker system, minor mechanical
misalignment may lead to a degraded coverage and
intelligibility.
Unless otherwise stated by the designer, the Intellivox
column with a-symmetrically placed transducers,
should be mounted with the ‘high frequency acoustical
center’ at the lowest position.
The Intellivox is mains powered, the mains ground
terminal should always be connected to a proper safety
ground. Other safety regulations may also require a
separate mains distribution network or an un-
interruptible mains power supply (UPS).
The Intellivox requires a signal source. For this
purpose preferably a symmetrical line level (0 dBV)
signal can be used. Alternatively the audio input can
be supplied by an existing 70V/100V network (if the
default transformer balanced input board is installed).
Refer to chapter 3.2 and chapter 2.4 for more
information.
The Intellivox is equipped with a RS-485 network
interface. This interface serves two basic purposes. The
first one is to adjust all relevant parameters (i.e. gain,
‘steering’ angle) during installation. Secondly it might
be used to integrate the Intellivox into a network for
continuous surveillance and ‘on line’ control. In cases
where these last mentioned network options are not
required, the RS-485 wiring can be omitted. One
should however realize that the existence of network
wiring greatly simplifies the transfer of the initial
parameters as well as any future DSP software
upgrades or functional check-ups, especially in
situations where a unit is located on a position which is
hardly accessible. Refer to chapter 3.3 for more
information about the RS-485 network.
If more then one unit has to be connected to the RS-
485 RS-485 network network, make sure that every
unit is set to a unique network address before
connecting to the RS-485 network. The network
address can be changed by connecting the individual
device via an RS-232 to RS-485 adapter to a host PC
running WinControl the appropriate software. More
information can be found in the help file of
WinControl.
