Chapter 3 System installation
C-MARK DRD28A equipment is simple to be installed and used. You only need to connect C-MARK the
DRD28A to a computer with the serial port cable. Then by operating the software of the computer, the
processing and setup of 8 channels audio signal input can be achieved.
A consolette can be set up through software control of C-MARK the DRD28A. It is suggested that this
mode be used in small audio amplifying fields.
The operation and installation steps are as follows:
Step 1:
Connect C-MARK DRD28A equipment with the computer directly through a serial port cable, and
connect the audio source input to the Line/MIC input interface of C-MARK DRD28A rear panel,
and connect the external amplifying device to the output interface of the rear panel (shown as the
following schematic drawing).

Step 2:
Switch on C-MARK DRD28A equipment, then wait for the lighting of its LCD screen and all indicating
light, and enters the normal working condition.
Step 3:
Add C-MARK DRD28A to its software. For more details, please refer to the chapter four Fast
installation setting of the control software.
Step 4:
Adjust the parameter setting of C-MARK DRD28A DSP processor through the DRD28A software in
line with application requirement.
Step 5:
By downloading current DSP parameter setting, the DRD28A can work seperately according to the
setup parameter, with computer control no longer needed.

FAQ Answers to frequently asked questions
1What features does C-MARK DRD28A has?
C-MARK DRD28A audio processor has 8 analog input and 8 analog output ports. It can
simultaneously process 8 channels signal through the analog input, and output the signal to the
corresponding port. Point to point or point to multipoint signal transmission can be realized
Specially designed DRD28A software helps the testers to carry on the system setting conveniently.
This software is direct-viewing. By dragging the mouse, you can complete may complete the
parameter setting of the audio signal transmitting. All the parameter settings are solidified in the
equipment. Once the setting is completed, the system can work separately from the computer.
2What is the delay for C-MARK DRD28A?
The delay can reach 87s when the signal is transmitted through C-MARK DRD28A.
3Must there be a real-time connection between C-MARK DRD28A software system and C-MARK
DRD28A system?
No. Each DRD28A equipment has memory cells, once the route connection setting is completed, we
only need to download and solidify this setting information to C-MARK DRD28A equipment, and the
DRD28A system will run separately, without any connection to the computer.
4In which fields can C-MARK DRD28A be applied?
C-MARK DRD28A audio processor can be widely used in fields such as stadiums, schools, hotels,
parks.
5Why can not C-MARK DRD28A software work properly?
Check whether C-MARK DRD28A software has been installed.
6Why can not the route configuration information be downloaded to correctly to the DRD28A
equipment?
Please check whether the equipment is online, or whether the parameter configuration in software is
consistent with the actual parameters or the equipment is connected correctly.
