3.3.2 Audio Outputs
In this menu amplifier outputs, preamp outputs and LINK connection for slave
equipmentare configured
a) Amplifier
Amplifier output manages the main amplifier and backup amplifier at the same time.
•
Master PA Vol, Master VA Vol, Mute:
•
Eq Enable y Eq Settings
: It allows to activate and configure parametric equalizer
at the input.
•
Loudness
. It activates the automatic equalization isophone system adapted to
human ear.
•
Advanced
. Advanced configuration parameters of the amplifier-
◦
Amplifier
N. It allows to activate or deactivate the amplifier supervision and
visualize the gain (19 kHz) and temperature gain.
◦
Common config.
The failure detection parameters and the 70 V lines mode
can be configured.
b) Pre-Out
Pre-amplified outputs can be used for external amplifiers for zone power boost or
emergency alarm recorder. Each output has independent volume adjustment.
•
PA Volume, VA Volume, Mute
.
•
Link to zone
. It configures the zones where it gets integrated, to receive the same
audio as this zone.
c) VA Rec-Out:
Recording output is assigned to output Pre-out 4, so t plays
voice messages emitted to the zones in evacuation mode
3.3.3 Speaker Line configuration. <Speaker Lines>
For each zone you can individually configure your label and line supervision
parameters.
•
Supervision
: Enables or disables line / zone supervision
•
Line Status:
Indicates if the status of the system is correct or faulty. Possible
status are:
◦
Sup. Off: Supervision deactivated
◦
Earth Fault: Leakage fault in speaker line
◦
Calibr. Error: Calibration error, impossible to calibrate line impedance.
◦
Invalid M: Out of range measurement.
◦
Open C: Open circuit or higher impedance than calibrated.
◦
Short C: Short circuit or lower impedance than calibrated.
◦
OK: Line measurement is ok.
•
LastMeas Z
: Reports the impedance value of the last measurement.
•
Nominal Z:
It is the impedance value saved at the time of calibration.
