modules installed (if 18 rooms were required then there would be 5 output modules installed).
The output connectors are RJ45 and their pin outs are fully described in the Section on Cabling. There are
two jumpers to configure, upper or lower tier on each module. These are already configured before ship-
ment and need no further adjustment.
B. This is a red LED and it will illuminate whenever there is a power short in any of the four output cables
connected to that output module. Please refer to the cabling section for proper wiring of the CAT-5 con-
nectors.
C. This is one of ten input connectors for the incoming audio. It is a screw terminal pluggable connector,
speeding installation and ensuring a durable trouble free termination of the audio cable. Please refer to the
cabling section for proper wiring of the audio connectors.
D. This is trim control to adjust the level of the incoming audio.
E. Max Audio Input is a digital switch that establishes how many audio sources can be selected from the
wall plate. If only 5 audio sources are available, then this switch would be set to 4 and the wall plate indi-
cator would only go as high as 4 before it returned to 0.
F. Page audio input (one of two). It is a screw terminal pluggable connector and it is designed to accept a
balanced line level input source, typically from a microphone preamplifier, mixer or telephone system.
G. There are two adjustments on each of the two page inputs. The trim adjust control is used to establish
the typical operating level (see Setup Section). The threshold control is set so that any signal on the incom-
ing line will automatically activate the page circuitry. This feature eliminates the need for a push to talk
switch on the microphone or near the microphone.
H. A red LED will illuminate any time the associated page circuit is activated. This is basically an installa-
tion aid.
J. This toggle switch enables or disables the ability to program the wall plates. Typically after a system is
installed and checked out this switch would be placed in the disabled position.
K. This toggle switch selects the type of page mode of operation that is desired.
FCFS (first come first served) automatically puts the first microphone to activate the page circuitry in
charge. The second microphone will not interrupt it.
Page One Priority will let the page one microphone take over at any time it is activated.
L. These two DIN type connectors are used to power the unit. One wall mount transformer will power a
minimum of 16 rooms (all rooms using the speaker outputs in each room) or 32 rooms if only headphones
and/or line level outputs are used (see section on cabling for more information).
