CHAPTER 2 CFM OPERATING PROCESS
CFM-1006
CFM-1006 can provide 8 net input signals and 10 Mic input signals to create a
16*8 intelligent mixer. The detailed process is shown in the diagram:
Each function module allows for configuration and modification of parameters
via NSP-100 software and can download them to the CFM hardware device.
CFM-1006 device can be used independently separated from computer at the
very moment of successfully downloading and confirming the DSP parameters.
The stand alone system structure is as follows

9
Copyright © 2009 Digispider. All rights reserved.
www.digispider.net
The DSP function can be controlled by the NSP-100 software.
1.Phantom power ON/OFF: CFM1006 can provide a +48V phantom power
for each input channel, just click Phantom button of the relevant number, when
the button turns green，it indicates that phantom power is providing power for
the Mic of that channel.
2. Gain adjustment of Mic: Select a certain channel Mic gain dialogue window
from IN1 to IN10, you can open the Mic gain adjustment dialogue window.
There are total 10 steps to choose, after a proper Mic gain rank is selected, this
detailed gain value will be indicated on the dialogue window in the software
interface.
3. Input level adjustment: The level control of all input channels can be
adjusted (from -60~+12dB). Select a certain level control window, open the
level control window. Drag fader to complete adjustment, the detailed level
value can be seen on the interface, also can be input a certain value into the
interface directly for setting.

4. DSP arithmetic：Noise gate, high-pass filter, low-pass filter and equalizer, all
of these have icons and a bypass I/O.
DSP adjust interface
5. Setting priority for input channel ：Priority setting for meeting
participators. When people who have high priority speak in MIC, the low priority
people’s level in input channel(s) will be decreased automatically. Setting
interface is as shown below:
Priority setting interface
Priority “0”is the highest, “1”is medium, “2” is the lowest. And the detailed
decreasing value can be set between -60~0dB when low priority user and high
priority user meet together, also the recover time for low priority user can also
be set.

6. Mix enable: Green indicates Mix is open, red indicates close.
Mix control I/O and mixer position
7. Mixer: after getting through the mix enable, Input channel enters a matrix
mixer. You can select several audio of inputting channels for mixing at a certain
output port via button in the matrix.
Right click the mouse then pop up the interface as follow:
Set Atrri to Default: set the mixer DSP parameters to default value.
Copy Atrri: Copy the mixer DSP parameters for the other device usage.
Paste Atrri: Paste the mixer DSP parameters from the other CFM.
Current Input Mix: open or close the all current input channel.
Current Output Mix: open or close the all current output channel.
All Mix: open or close the all mix channel.
Set Attributes: adjust the level of the channel.
AutoSet Attenuation: set the auto adjust mode for the CFM-1006.
In the auto mode, the user should open the all mic and speakers. The mixer will
be adjusted automatic after the auto test for avoid the feedback.

CFM-0800
Being different from CFM-1006 conference mixer, CFM-0800 conference
extended unit only has local Mic input ports, net input/output ports, but no
analog output ports. So, it has to be used together with CFM-1006 device for the
extension of Mic input ports. The process of signal working is as follows:
One CFM-1006 can receive eight CobraNet signals from the network. So there
are eight CFM-0800 can be connected to the CFM-1008 for expand.

CHAPTER 3 BASIC OPERATION
Hardware of CFM conference mixer can provide various forms of audio ports,
LED/LCD display and all of the function setup can be customized by the
command of NSP-100 software via network. CFM can be used independently
separated from NSP-100 software after the very moment of successfully
confirming parameter setup.
According to different application situation, it can divide into two modes: stand
alone mode and network mode
STAND ALONE MODE
CFM can work in stand alone mode, controlled by dedicated NSP-100 software.
Recommend to use this mode in small conference discussion system (the
number of microphone less than 10 and number of mixer less than 6)
In stand alone, connect the computer network card to the CFM -1006, whose
functions are controlled via dedicated software NSP-100, with cross-over cable.
The operation is listed below.
Step 1
Connect the computer network card to the CFM -1006 with cross-over cable,
conference microphone to the Line/Mic IN ports at the rear panel and output
equipment to the LINE OUT ports. The maximum length of the CAT-5 cable is
100m.
Step 2
Startup CFM, and wait for CFM start to work in normal status with all LCD and
indicator lights turn light.
Step 3
Add the CFM into the software NSP-100 in a right way, please refer the NSP-100
user’s manual and CFM quick start guide.
Step 4

15
Copyright © 2009 Digispider. All rights reserved.
www.digispider.net
According to the situations, it is possible to adjust the gain of mic, gain of output,
priority and something like DSP processing to enhance effect via the dedicated
software.
Step 5
Users can confirm the previous setup after attaining the expected output effect
and next time can use CFM independently without computers.
EXPAND MODE
The input channel can be expanded by CFM-0800 using the CobraNet port if the
conference system need more than 10 mic input. One CFM-1006 can receive
eight CobraNet signal from the network. So there are eight CFM-0800 can be
connected to the CFM-1008 for expand.
Step 1
Using switch to set up network between several CFM devices and the controlled
computers. The maximum length of the CAT-5 cable between the switch and
CFM device is 100m.
Step 2
Startup CFM device, and add every equipment into the NSP-100 software
system. Then, set up the receiving/sending relation between them. Please refer
to the NSP-100 software user’s manual or CFM quick start guide.
Step 3
According to the situation, adjust the I/O of microphone and mixer, and get into
use. Please refer to the NSP-100 software user’s manual or CFM quick start.
