Intellivox DDC Installation Manual Installation Guide EN 6

2.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:

•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.
