less than 30 meters, the cable can be straight through or crossover. If the distance between
devices is more than 30 meters, the cable must be a crossover.
Refer to Table 1 for the Ethernet pin types.

• 1070V audio connection cable
This cable is used to connect the DCS to the DA as well as the DCS to the loudspeakers in the
broadcasting zones. Shielded cables with a cross-section of 1.3mm
2
(wire gauge of 16AWG)
are recommended.
• DA backup power supply cable
This cable is used to connect DCS, DA to DC backup power supply. The wire of 9AWG is
recommended for DA, and the wire of 16AWG is recommended for DCS.
• Power amplifier audio input cable
Audio input cables are provided in the package containing the DA, but the lengths of these
cables are limited. If these cables cannot meet the requirements of the system wiring situation,
users need to obtain or create appropriate cables themselves. Please prepare such audio
input cables with the specifications as listed in Table 2. This cable should be a direct
connection.

DA fault information output
• When the DA is working properly, the
output voltage is VCC(12V-24V)
• When the DA faults, is protected, or
undergoes self-testing, the output
voltage is GND(0V)
