used to control the volume of the input channels respectively. Knob
“
MIC VOL
”
is used to control
the volume of microphone. Clockwise turning represents volume increase, while anticlockwise
turning represents volume decrease.
Volume of the 100 zones is integratedly controlled by the knob on the panel of the equipment, i.e..
the equipment is not provided with separate control for simultaneous volume increase or decrease for
the 100 zones.
4.4 Paging and Priority Functions
Paging includes remote paging and paging of microphone connected to the equipment. The control
of zones by the remote pager enjoys priority over addressable host and PC control software. When
the zones are switched upon on the remote pager for paging, the five zone scope selection keys on
the panel of the equipment can be used to view the operation status of zones during the paging. Any
operation over the zones by addressable host and PC control software other than the operation by
remote pager will be invalid.
When the remote pager is conducting paging operation for a particular zone, if the zone is switched
on on the remote pager, then all the zones for background music will be switched off, then the paged
zone will be switched on. After the paging, use key
“
ALL OFF
”
on the pager to switch off all the
zones or the power of remote pager, and all the zones will resumed to the pre-paging operation status.
When the pager is conducting paging for all the zones, gently press
“
ALL ON
”
key on the remote
pager to switch on all the zones. In this case, the equipment will switch off the zone playing
background music first, then switch on all the zones. After the paging, gently press key
“
ALL OFF
”
on the pager to resume the status of playing background music of the zones.
The system can also perform paging over the zones by the microphone connected to the equipment.
Prior to the paging, gently press the key for ringing alert
”
on the panel to obtain the ringing tone.
Ringing volume can be adjusted by the ringing volume adjustment knob (1) on the panel of the
equipment. Adjust the microphone volume to the optimal position (until no howl is available for the
microphone), and then carry out paging for the zones.
When the system is playing the audio input by AUX1 interface, paging over zones can also be
performed by microphone. Input signal of AUX1 interface and ringing signal are the same priority
signal, and the output terminal can transmit three signals, any of which can cover the audio signal
input by AUX2, AUX3 and AUX4.
Note for Operation:
1.
When the host is off, at least 10 minutes is required for re-energization.
2.
When withdrawing from the remote paging (by pressing key
“
ALL OFF
”
of the remote pager),
please power off the microphone of remote pager at the same time, otherwise, the surrounding
sounds can still reach the zones switched on after the resuming via the microphone of pager.
