2. DC POWER INPUT AND BATTERY CHARGE TERMINAL
The emergency power supply and battery charging port can connect DC 24V battery.
- Priority is given to AC power when both AC and DC power are both input. DC power is activated when
AC is cut off.
- When operating in emergency power mode and the battery voltage is about 20V, system operation
indicator “DC” will flash and if the voltage drops below 19V, system will be in standby mode to protect the
battery.
※
Notices
1. When in standby mode due to low voltage, battery can be recharged (20V) by AC power.
2. Before connecting the battery, please check for proper polarity (+,–).
3. Please note that it may cause electric sparks when connecting the battery.
3. AC FUSE
If any problem occurs with the AC power, fuse in the unit will cut the AC power to protect the unit. When
replacing the fuse, replace with the same capacity as listed.
4. AMP IN/OUT TERMINAL
External amplifier input terminals are located in the back of the unit when separate/additional power
amplifier is needed.
※
Note: When using built-in amplifier, input/output terminals must be connected to each other.
1) AMP OUT (AMP OUT)
- Connect built-in amplifier (100V/33.3
Ω
or 70V/16.6
Ω
) terminals to AMP IN terminals.
- Pay attention to Group A,B and polarity (+, –) connections.
2) AMP IN (AMP IN)
- Amplifier out terminal which can be connected to (AMP OUT) or connect to external amplifier. The input
can be used for local broadcast through speaker ZONE selection button on the front panel.
3) How to Connect
- When using only the built-in amplifier:
AMP OUT (A, B) to the AMP IN (A, B), while observing
correct polarity (+,–).
- When using both Internal and External Amplifier:
Connect an output of the two groups to the amplifier input
and the external Amplifier output to the other group input.
※
Caution: When connecting an external amplifier, connect
HIGH IMPEDANCE output to AMP IN terminal.
Do not connect amplifiers rated 1200W or
higher. Also, each ZONE output must be 500W
or less.
