Specifications

Each intercom line has its own intercom line terminal impedance switch placed at

the rear panel of the unit.

By default, all the switches must be in Master (M) mode.

CAUTION: Never leave the intercom line without terminal impedance, because a bad

operation of the units connected to the line would take place.

LINK SWITCH

The channel link switch (LINK ABCD) , allows to join all the the channels so that the

same signal appears in all channels. If the channels are linked, the units connected to the

channel A can communicate with the one connected to the channel B, C and D and vice

versa, and the calls carried out in any channel will arrive to all the units connected to all

channels. If the channels are linked, the units connected to the lines are no longer

independent, forming a single group where everyone is talking and listen for the same

communication channel. In the base station this common channel is channel A. The

remaining channels are no longer operational. To make the link, press the LINK switch

located on the rear panel.

Linking is commonly used in rehearsals to share all the team information.

CAUTION This operation must be carried out with the base station power off to avoid

undesirable transients.

EASY LINK. ALL INTERCOM LINES IN A SINGLE CONNECTOR

The EASY link connectors allows connection of all the intercom lines to another

base station with a single not inverting RJ45 CAT5e or better cable (widely used in

computer networks).

Each intercom line on the connector has a LED power indicator, so that a short circuit in

any of the lines, will mean that the correspondent LED remain off, and the rest of the lines

are operative. The connector is duplicated (both connectors are wired internally in parallel)

allowing easy daisy chain connection between bases. Maximum lenth of the wires used

must no reach 20 meter in total to avoid voltage drops. When more lenth is needed the

installation must be done with standard XLR3 cabling.

The main intercom wiring must be done from the Master intercom base station and by

using the standard XLR3 connectors.
