Difference between D SERIES V3.0 and V2.0
Unlike the D series V3.0 version, which uses high-quality capacitors, power tubes, and other imported components, the V2.0 D series utilizes Chinese domestic components. This version primarily focuses on cost-effectiveness to meet various customer needs, while still retaining the features of the High Quality Nichicon capacitors and 2 ohms stable operation.Exclusive to V2.0, silicon-carbide output devices deliver cool-running, high-efficiency power; a temperature display active by default for continuous status monitoring; and a rear-mounted bracket that creates a vibration-isolated, road-tough rack connection.
D4-1300 V2.0 FEATURE:
►High Quality Nichicon capacitors from Japan
►Silicon-carbide transistors,Stable at 2 ohms long-term load
►Active PFC,soft-switching for high adaptability
►Wide voltage range of 90V-270V for harsh environments
►Efficiency,energy conservation, environmental protection
►Standby sleep mode,power-saving and durable
►High Quality XLR*/Speakon connectors
►Damp Factor >5000 @20-200Hz,Powerful and profound low frequency
►Temperature display module, real-time monitoring
►Rack-locking rear bracket—shock-absorbed and flight-ready
►D4-1300 ideal for line array,full range speaker.(Not recommended for subwoofer)
Optional Temperature Display Screen
REAR BRACKETWhen the amplifier is mounted from the front, the rear bracket connects to the back of the rack case, providing support for the weight of the amplifier's rear. By securing the rear of the amp, the bracket minimizes movement and stress on the internal electronics, which is critical during transport where vibrations are constant.

Dimensions and Cooling system
NOTE:
The size is 437mm inside of the device(without the cover plate and front panel).The size is around 472mm of the complete device,but a little bit different size in the different front panel.Some series with different size that had not shown,please learn it in the parameter.
Tunnel through cooling system:
Cold air comes in from the front panel of the equipment, forms a duct through the radiator to take the heat away and out from the rear panel of the equipment.
