1/2. AMPO CH1/CH2 output:
The output provides the 100V (EU type)/70V (US type) audio signal from power amplifier, CH1 is
for internal amplifier channel, and CH2 is for external amplifier channel.
3. A/B line zone outputs (zone1~zone8):
Connect the loudspeakers to the zone outputs. Each zone output is consisted of two
loudspeaker line outputs. The open, short and bad impedance faults can be detected by system
for both speaker lines.
The secondary unit is capable of handling 1000W speaker load per zone, 2000W max. per
unit.
4. Relay output control:
There are eight relay outputs, and they can be programmed as close/open contact to an external
device.
5. EVAC control input:
There are nine EVAC inputs on BTQ-SG8/SL8, they can be programmed for
and to monitor the external contact. Each channel supports 3 modes:
Monitored contact mode: The system can monitor the evac input and detect faults (4 status:
on, off, open and short).
Disable: The cables which connect to evacuation input will not be monitored (faults will not be
detected).
Voltage mode: Trigger the input by a voltage change (OPEN/CLOSE) with an external 24VDC
source provided by external devices. The cable is not monitored in this mode.
6. 24 VDC output:
The 24VDC (max. 0.8A) power is shared by the two 24VDC outputs on BTQ-SG8/SL8 and the
remote consoles.
If the BTQ-SG8/SL8 is connected to an external 24VDC power supply such as connect to
the battery charger, then the max. current will be 1.3A.
7. Logic input control:
There are eight logic inputs designed to work with simple contact or button, that are two states
input (open contact, close contact), which can be specified as logic input to monitor security
devices such as power supply, and those control input can put the system into a security mode
