1. INPUT: DSC02 Dante Interface receiver,
connecting with Dante network switch.
The network LED will illuminate yellow when
the unit is connected to the Dante network.
The network LED will illuminate green /
blink when the unit has an IP address and is
communicating to the Dante network.
Note: Dante receiver will need the power
from the switch with PoE function..
Note: In AUTO mode, when receiving the
signal from Dante network, the amplifier will
be triggered ON.
2. LEVEL : Adjust the level of output.
3. HPF: High Pass Filter (80Hz)
4. TRIGGER IN : Apply 12VDC to this
connector to active the unit.
5. TRIGGER OUT : Provide 12VDC to
trigger another device.
6. OUTPUT SELECT SWITCH :
4Ohm/8Ohm and HIZ for 70V/100V.
7. SPEAKER : Connect with 4 Ohm or
8 Ohm speakers.
8. 70V/100V: Connect with
Constant-Voltage speakers directly.
