CABLE CONNECTIONS
The TRAIL103 supports high or low impedance operation. In this sense, its rear panel
has 2 Euroblock connectors to select its working mode. The HI-Z INPUT connector allows
the system to work in high impedance (100V line) and the LO-Z INPUT connector in low
impedance.
(*)
The type of connection depends on the type of installation: on lighting rail, on surface or
on truss. By default, the TRAIL103 is mounted for rail installation. In this case, its
connection is by means of stripped cable clamp terminals. If you wish to install on a
surface or truss, the audio cables must be cut for connection to a screw terminal block
(for more information see chapter 7).
To make the connection in the speaker, it has a male Euroblock type connector, which is
connected to the high or low impedance input (
HI-Z IN
or
LO-Z IN
), depending on the
type of installation:
•
HI-Z IN
: the connector for the 100 V line will allow you to configure the maximum
power that each unit will work with. Thus, in areas where a low sound level is
desired, terminals 0 (black wire) and 15W (blue wire) will be used to connect the
speaker; while in areas where a higher level is desired, terminals 0 (black wire) and
30W (red wire) will be used. If the speaker is used in 70V installations, the
corresponding powers for the 100V position will be reduced to half those indicated
on the connector terminals. In the case of installations at 50V, to a quarter.
