PageNet 88
Zone Paging System
Operating Manual

ProductDescription
The PageNet is an 8 zone matrix system designed to accept up to 8 zone paging microphones, 4 program sources and 1
priority input. The heart of the system is the PageNet 88 matrix which allows any of the 4 program inputs to be assigned
to any of the 8 output zones. Up to 8 zone paging mics (PageNet 88M only) can be used with the system, allowing any
combinationofthe8zonestobepagedfromanyof8differentlocations.ThePageNet88Misanattractive,compactdesk

to confirm to all other users that the system is busy. An internal pre-announce chime (defeatable) will automatically
trigger into the desired zones when they are paged from any of the mics.
PriorityMuting:The PageNet system features multiple levels of priority.PagingMic 1 will mute Mics 2-8 while Paging
Mic 2 will mute Mics 3-8. Any program source operating in to a selected zone will be muted by any paging mic when an
announcement is broadcast in to that zone.
An added feature of the PageNet system is that zones can easily be removed from the paging function via front panel
buttons on the matrix. For example, if a meeting room in a hotel is not to be disturbed, then that zone can be easily taken
out of the paging chain. Likewise at the end of the meeting, the room can again be added to the paging function.
The PageNet 88 matrix includes treble, bass, program level, mic level, and master level controls for each zone. The rear
panel has 4 auxiliary inputs with trim controls and 8 line level XLR inputs designed to accept the audio input from the
PageNet 88M Zone Mics. Eight 15 pin ‘D’ female connector are also included to accept the switching and logic
information from the zone mics. Outputs to the zone amplifiers are provided via 8 line level XLR outputs.
The PageNet system has facilities for DC backup and also includes evacuation and alert tones which can be triggered
remotely. These “emergency” tones have overall priority and, if activated, will be heard in every zone regardless of any
switch setting. An audio sum, emergency input is also provided. The PageNet is in a metal 2 rack unit chassis suitable
fordesk or rack mounting. The unitwill operate from 240VAC-50Hz,or 12-24VDC. 115VAC-60Hzisavailable on special
order.
PageNet 88, Zone Paging System
Front Panel Features
Prog 1, Prog 2, Prog 3, Prog 4 Buttons
Eachzone has a program select function where any one of the 4 program/auxiliary inputs can be switched on in that zone.
To select a program simply depress one of the program buttons. The unit is designed so that only one program can be
active per zone. In other words, if program is running through a zone and a second program button is selected, then the
first one will automatically switch off.

Treble Control
Each zone has a recessed (screwdriver adjustable) treble control. Setting this control in the centre position will give a flat
treble response. Adjusting the treble control in a clockwise direction will provide up to 10 dB of treble boost @ 10 kHz.
Adjustingthetreble control in a counter-clockwise direction will provide up to 10 dB of treble cut @ 10 kHz. This control
affects everything running through that particular zone.
Bass Control
Each zone has a recessed (screwdriver adjustable) bass control. Setting this control in the centre position will give a flat
bass response. Adjusting the bass control in a clockwise direction will provide up to 12 dB of bass boost @ 100 Hz.
Adjusting the bass control in a counter-clockwise direction will provide up to 12 dB of bass cut @ 100 Hz. This control
affects everything running through that particular zone.
Prog Control
This control adjusts the level of the selected program source in that particular zone. As mentioned earlier, the matrix will
accept up to 4 auxiliary/program sources. Trim (gain) controls are provided on the rear panel so that all of the sources can
be matched in level. Therefore when you change programs in a zone by pressing the front panel buttons, the level
between the sources should be consistent. The ‘Prog’ control (screwdriver adjustable level control on the front panel)
can be seen as the overall auxiliary level control for that zone.
Mic Control
The PageNet matrix will accept up to 8 x PN88M zone paging microphones. Each has the ability to select and page into
any combination of zones. A ‘Mic’ level control is provided on the front panel for each zone. This control governs the
level at which paging occurs in that zone, from any mic. Each microphone also includes a trim (gain) control in the base
so that each can individually be setup to compensate for different voice levels, or for high ambient noise situations. The
trim control simply allows for each mic to be setup for a particular application. The overall level of paging in each zone
is controlled by the ‘Mic’ control on the front panel.
Master Control
Each Zone has a Master level control labeled Master 1, Master 2 etc. This control adjusts the overall level for that zone.
In other words, the level being sent to the zone amplifier. The Master level control affects both the program and mic
inputs, meaning that while both the ‘Prog’ and ‘Mic’ levels can be adjusted individually, they are both affected by the
Master control. When setting up these level controls, standard gain structure rules apply. For example do not have the
masterlevelat near maximum if both the ‘Prog’ and ‘Mic’ levels are turned way down. The general rule is to try and have
all level controls set so that nothing is turned all the way down, or near maximum.
The controls mentioned above are duplicated for each of the 8 zones.
Page Enable
Eight buttons labeled Zones 1-8 are provided under ‘Page Enable’. This section allows zones to be removed from the
paging function. With all 8 buttons pressed, paging can go to any zone. A zone button in the ‘out’ position means that
that particular zone cannot be disturbed by paging. The zone will however still receive any selected program source as
well as any emergency signal that has been activated. This feature is especially useful for meeting or conference rooms
which may not wish to be disturbed by paging announcements.
Power Switch
The switch marked “Power” turns AC mains power ‘On’ and ‘Off’ to the PageNet system. Rocking the switch in to the
‘Up’ position turns on the AC power. When the switch is in the ‘On’ position, a blue LED located above the switch will
illuminate. If the PageNet matrix is connected to a 12-24 volt DC supply, this switch will not effect the operation of the
system from the DC supply. If both AC and DC are connected, then the PageNet will continue to operate normally when
this switch is turned ‘Off’. The DC supply needs to be disconnected from the rear panel to completely ‘turn off’ the
PageNetmatrix.

Rear Panel Features
AC Power Inlet
The 3 pin IEC power inlet is located on the bottom left of the rear panel and accepts a standard mains power lead fitted
with an IEC connector. Before plugging in a power lead, please check the rear panel to ensure that the voltage label
shows the correct AC operating voltage for your part of the world. The inlet is equipped with an in-built AC fuse holder
fitted with a 1 Amp slow blow fuse plus a spare fuse. Pleaseensurethat the mains power cord is disconnectedbefore
attemptingtocheckor replacethis fuse. Power consumption is 25 VA (max).
Terminal Strip
The terminal block below the mains power inlet provides a number of functions. A ‘Phoenix’ connector block (supplied)
can be unplugged for easy cable connection. This terminal block carries the following features:
12VDC: ThePageNetmatrixwilloperatefrom12-24VDC.Simplyconnect DC power source to the +/– terminals.
SUM: Thiscan be seen as a 5th auxiliary input. Connecting a linelevel source to the ‘SUM and ‘COM’ (see below) allows
a 5th input to be active to all zones. This input mixes with all other inputs and is transmitted to every zone irrespective of
the status of ‘Page Enable’ section. The 5th or SUM input can become a priority input by simply making and holding a
contact closure (COM and EMERGENCY). When an EMERGENCY contact closure is held, the SUM signal will have
overall priority and be broadcast into every zone (including de-selected zones) while the contact closure is held. Such
an input may be used for an external evacuation signal, or for special pre-recorded announcements. A Trim control for
the SUM is provided internally.
EMERGENCY: When used in conjunction with COM as a contact closure, this trigger will mute all program sources
while the closure is held. It may be used in conjunction with the ‘SUM’ input (see above) or simply used as an overall
mute switch (possibly to shutdown the unit in the event of a separate evacuation system being activated)
ALERT: The Alert terminal is an activation point (when used with COM) for the in-built Alert tone generator. The Alert
tone will mute all program sources when it is active.
EVAC: The Evac terminal is an activation point (when used with COM) for the in-built Evacuation tone generator. The
Evac tone will mute all program sources when it is active.
15 Pin Connectors
Eight15 pin ‘D Sub’ connectors are provided as a logic input from each of the8zone microphones. 15 core shielded cable
is recommended (pin configuration-back page). Cable lengths from the matrix have been tested to 100 metres. Micro-
phones1 and2havepriorityover Mic’s3-8andneed to bewiredbackto the matrix.Theseneedto be wiredwithout
looping. Microphones 3-8 however can either be cabled back to the matrix or ‘daisy-chained’ (15 pin input and output
connectors are provided on each mic). No more than 3 mics are to be ‘daisy-chained.’ Although the 15 pin logic cables
can be daisy-chained, please note that the audio from each mic (mic cable) needs to be individually wired from each mic
back to the matrix (see Zone Inputs).
Zone Outputs
An output is provided for each of the eight zones. Each is an active balanced XLR connection with a nominal level of 1.5
volts @ 600 ohms. This signal is designed to run into the balanced line level input of a power amplifier. It can however
be used with unbalanced inputs over reasonably short runs. The pin connections are; pin #1-earth; pin #2-high (+); pin
#3-low (-). When used in unbalanced applications, do not connect Pin 3 to ground.

Zone Inputs
The matrix includes 8 zone inputs. In other words, the audio from each of the PN88M zone microphones. Each of these
balanced XLR inputs is line level. While other line level sources could be plugged into these inputs, the only way to
direct them to go anywhere is via a PageNet mic console. Much of the switching logic for the system is included in the
zone microphone which, apart from pre-amping the signal from mic to line level, also tells the system where each input
is to be sent. In summary, these inputs are really only designed for PageNet zone mics. Please note that the audio from
eachmic must be wired back to the matrix.
Program Inputs
4 program source inputs are provided. Each input features dual RCA inputs and is suitable for a variety of sources
including Tape decks, CD players, digital message players and wireless mics with line outputs.
Program Input Trim Controls
A recessed trim (gain) pot is provided for each of the 4 program source inputs. The trim pots are provided so that each
source can be matched in level so that the volume is consistent when a user switches between program sources in a
zone.
OtherInternalAdjustments
Thefollowing adjustments involve access totheinside of the PageNetmatrix.This should only beattemptedby a
qualifiedtechnician. Always turn off the AC powerandremovetheACpowercord before attempting to access the
insideof the unit.
Pre-Announce Chime Defeat: The PageNet system ships with an active pre-announce chime meaning that a
chime is activated automatically when a zone is paged. The Pre-Announce chime can be defeated for any or all zones by
moving an internal jumper (for each zone). A pre-announce on/off jumper for each zone can be found on the main board
behind the Zone Input XLR’s.
Pre-Announce Level Control: This pot adjusts the level of the Pre-Announce chime. The one pots affects the
pre-announce level in all 8 zones. The pot is labeled ‘R70’ and can be found on the main board behind the Zone Input
XLR’s.
Alert and Evac Tone Level Control:The Evac/Alert trim pot, labeled ‘R71’, can be found on the main board
behind the Program Input RCA’s. It adjusts the level of both the Alert and Evac tones.
Sum Level Trim:The Sum level trim pot, labeled R72’, can be found on the main board behind the Program Input
RCA’s. It adjusts the level of the sum input (rear panel Phoenix connector).
WiringandConnectorInformation
