The ASCENT EC2400 4 in 1 MPEG-4 AVC/H.264 HD encoder is a professional HD audio & video encoding

and multiplexing device with powerful functionality. It is equipped with 4 HDMI (or SDI) input channels

allowing for 4 HD programs can be processed simultaneously. It adopts the MPEG-4 AVC/H.264 High

Profile encoding format to guarantee the highest picture quality. The EC2400 has an ASI input and can

multiplex the input TS with the 4 encoded programs to generate a stream output through ASI and IP. In

addition, the PSI/SI information can be inserted into an MPTS output. In conclusion, the EC2400’s highly

integrated and cost-effective design makes the device widely used in varieties of digital distribution

systems.

between 2 rows of machine frames should be 1.2 ~ 1.5 m and the distance

between a machine frame and a wall should be no less than 0.8 m.

Machine Hall Floor Electric Isolation, Dust Free

Volume resistivity of ground anti-static material: 1×107 ~ 1×1010Ω

Door & Window Install rubber strips to seal door gaps and dual-level window glasses.

Wall Can be covered with wallpaper or non-bright paint.

Fire Protection Fire alarm system and extinguisher

Power Device power, air conditioning power, and lighting power should all be

independent of each other. Device power requires AC power 220V 50 Hz.

Please check carefully before running.



Good grounding designs are the basis of reliability and stability for these devices. Good

grounding is also the best guarantee against lightning arresting and interference rejection.



All machine frames should be connected by protected copper strips



Coaxial cable outer conductors and isolation layers should maintain proper electrical

conduction with the metal housing of the device.



The grounding conductor should be copper in order to reduce high frequency impedance.



The grounding wire should be as thick and short as possible and avoid circling.



Users should make sure both ends of the grounding wire are good conductors and rust-

resistant.



Users should not use any other device as part of the grounding electric circuit.



The area of conduction between the grounding wire and device’s frame should be no less than

25 mm2.



Connect the device’s grounding rod to the frame’s grounding pole with copper wire.

The grounding wire conductive screw is located at the right end of the rear panel, and the power

switch, fuse, and power supply socket are right next to that. The power switch is on the left, the power

supply socket is on the right, and the fuse is between them.



Connecting Power Cord

Insert one end into the power supply socket, and insert the other end to an AC power source.



Connecting Grounding Wire

The grounding resistance should be less than 1Ω.

Caution

Before connecting power cord to EC 2400 4-in-1 MPEG-4 AVC/H.264 HD

Encoder, user should set the power switch to “OFF.”

The signal connections include the input signal cable and the output signal cable. The cables look like
