It’s Under Control
®
SPEAKER WIRE TERMINATION
Install the four supplied phoenix connectors into the audio zone outputs on the
AD-4x. Connect the positive and negative wires for each audio channel output,
keeping the proper orientation of positive and negative signal for each speaker
connection. Typically, two-conductor speaker wire uses red to denote positive
and black to denote negative. Some types of wire indicate positive with a line
running through the insulation. Four-conductor wire can also be used. This
has four separated wires in one outer jacket, making it possible to run a single
speaker wire to a zone for its pair of speakers. This type of wire typically uses
red and black for one speaker and white as positive and green as negative for
the second speaker.
CAUTION: Do not short speaker wires together if they are connected to
the AD-4x, as damage to the unit may result.
IR CONTROL OF AD-4x
A 3.5mm mono mini jack labelled CTRL IN, located on the rear of the AD-4x
allows for hard-wired IR control from a control system. A library of infrared
codes is available within the RTI Integration Designer programming software or
on the RTI website (accessible to RTI dealers only). Installations can have up to
8 AD-4x units installed. To allow discrete IR control each unit is given a unique
ID (see page 13). Discrete IR code libraries are available for each unique ID.
RS-232 CONTROL OF AD-4x
A DB-9 jack offers RS-232 control of the AD-4x from an RTI or third-party
control system. A set of RS-232 codes is built into the Integration Designer
programming software and a two-way driver is available on the RTI website
(dealer section).
NOTE:
DO NOT use both RS-232 and IP for control simultaneously. Using both
control methods at the same time will affect control reliability.
