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.
Adjusting the treble 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
master level at 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
PageNet matrix.
