11. RC-NET Input/Output Port
Control signal can transmit through this network port.
RC-Net is based on RS-485 transport protocol, which owns function of RS485 data exchange, to
realize large-scale real data transmit.
12. LAN& RC-NET Switch
Use this switch to choice Network control way, you can determine to control it by Ethernet or
RC-NET.
13. LAN Network Control Port
DLM808 can connect with Ethernet switch via this port. On LAN network control port, you can
see two LEDs, they are connection status indicator (green) and signal transmit indicator(yellow).
-- If the yellow LED goes out, means no signal transmits; while if yellow LED is on, but green one
goes out, means the device detects network, but no connection.
-- If green LED is on ,means network connects well.
14. Optional Module
Usually it is prepared for DANTE module to insert in, which can be used for audio input/output
expansion.
15. Power Inlet
Connect AC voltage, 100-240VAC, 50-60Hz.
16. Power Switch
Press it to turn on/off the device.

DLM808 can connect with PC by internet
port on router. After successfully connected,
please click the file named SystemEditor on
PC, you can see initial page as below picture
shows, which can set connection of each
device.
1. Configuration of IP Address
When connect DLM808 with PC by internet port on router:
Before connect devices on software control page, please set IP
address of DLM808 and router first, below gives steps(pay
attention that the toggle switch on DLM808 rear panel should be
at LAN side):
1). Click “Connect” control on top right corner, a search dialog will
jump up, click “Scan” button, it will automatically search IP and
MAC address in the system, as below picture shows. Then click
“Connect” button to build communication. The “Status” control in
top right corner indicates the communication status, which will
light green if connect right, while off means fail to connect.
2). If fail to connect following above step, then please key the IP address in “Choose IP” text field,
then click “Connect” button. After connecting successfully, you can see device information in the
lower-left corner, as below picture shows.
2. Configuration of Device Connection on Initial Page
Below picture shows you the connected status.
How to connect?
1). Add Device
Click the device under “Config DeviceList”
and drag it to the middle area, then release
mouse, the device will be added to this
area,
2). Delete Device
Right-click the device, select “Delete
Module” to delete it.
3). Configuration of Device ID
Right-click the device, select “Change DeviceID” , a dialog appears as below picture shows,input
a new Device ID in the text field, then click “OK” button to change
it.
After successfully connected devices, double click DLM808 on this
initial page to enter DSP control page, which will be introduced
later.

3. Input DSP Channel
1). Device Data
After connecting PC with DLM808 and communication right, here you can see information about current
channel, device name, ID number etc. If Connect Status icon is green, means communication is right; While
off means communication is fault.
2). Expander/Gate
In this area, you can adjust parameter of EXP/Gate , the curve in coordinate will change with parameter’s
change.
The Expander is used for adding input dynamic range according to user’s demand.
- Threshold
Click the control to set Gate threshold of selected channel. This threshold value determines the open level of
Gate. Actually, all input audio signal that higher than threshold value can go through, the range of threshold
value is -64dB to 20dB.
If input signal is lower than threshold, the Expander can enlarge it with setting ratio, then output the signal.
If input signal is larger than threshold, output signal will be the same with input signal, which means ratio
is 1:1.
If adjusting the ratio to max(∞), Expander will change to noise Gate.
- Ratio
Click the control to set ratio of input signal to output signal. That is the dynamic change value of Expander’s
input signal/dynamic change value of Expander’s output signal.
- Attack
Click the control to set the interval time from selected channel’s signal beyond threshold to open noise Gate,
the time can be set from 10 to 150ms.
Signals that increase slowly need lower attack, because if set the attack value too high, it may cause “click”
noise. Actually, all Gate may cause “click” noise when operation, but it can be avoid if set properly.
