16 VA-EOL per zone).
5. AMP: The amplifier source which is connected to the zone (external amplifier, VO3 etc.).
VO3 is channel that only generate the pilot tone in case no amplifier channel is in used.
6. ZA: The impedance value (ohm) for Line A of one zone.
7. ZB: The impedance value (ohm) for Line B of one zone.
8. ZA&B: The impedance value (ohm) for Line A and Line B in parallel.
9. Realtime: The realtime impedance measurement of Line A and Line B in parallel.
10.Diff (%): The difference between Reference A/B and Measure value (ohm) in percentage.
11.Tolerance (%)---ADJ.: Define the tolerance of impedance value to detect a bad impedance
fault. For instance, if the reference is 1000 ohm and the tolerance is set to 15%, the range of
good impedance will be 850 ~ 1150 ohm. If the measured impedance is 1300 ohm, a bad
impedance fault will be recognized by the main controller/secondary unit.
: Set the tolerance of impedance value via arrow up/down button.
Synchronized adjustment: If the zones enable this option, their tolerance value will be
adjusted synchronously.
12.GET.: When the system is constructed, users needs to get the impedance value of the
speaker lines for further reference. This value will be utilized to detect faults of zones.
13.Clear.: Reset the reference value. This will disable the zone monitoring, but the measured
value is still updated.
5.1.11.2.3 Monitoring settings of VA-EOL (3 wire)
1. EOL: Indicate the zone of VA-EOL. The displayed number on [EOL] column depends on the
quantity of VA-EOL users have set on [EOL Size].
2. Enable: Enable/disable the monitoring of each speaker line branch by using VA-EOL.
3. ID: Set the ID of the connected VA-EOL.
4. ZA&B (ohm): Detect the impedance value of speaker line A and line B when the connected VA-
EOL switches off.
5. ZA + /A - realtime (ohm): Detect the impedance value of paralleling speaker line A+ and line A-
when connects to the VA-EOL.
6. ZB+ realtime (ohm): Detect the impedance value of paralleling speaker line B+ when connects to
