To connect your TOPP PRO RT-DRIVE DLM808 to a PC, follow these steps:

1. IP Address Configuration:

• Ensure the toggle switch on the DLM808 rear panel is set to the LAN side.

• Open the SystemEditor software on your PC.

• Click the “Connect” control in the top right corner to open the “Device Scan Window”.

• Click the “Scan” button. The software will automatically search for the IP and MAC addresses of connected devices.

• Select your device and click the “Connect” button to build communication. The “Status” control will light green if the connection is successful.

• If the automatic scan fails, manually key the IP address into the “Choose IP” text field and click “Connect”.

2. Device Connection on Initial Page:

• **Add Device:** In the SystemEditor, click and drag the DLM808 device from the “Config DeviceList” on the left to the middle area of the window.

• **Delete Device:** Right-click the device in the middle area and select “Delete Module”.

• **Change Device ID:** Right-click the device, select “Change DeviceID”, input a new numeric ID (4 bit) in the dialog box, and click “OK”.

After successfully connecting the device, double-click its icon to enter the DSP control page.

Within the DSP control software for the TOPP PRO RT-DRIVE DLM808, you can adjust the following parameters for each channel:

Expander/Gate (Input Channels only):

• **Threshold:** Sets the level (-64dB to 20dB) at which the gate opens. Signals above this level pass through.

• **Ratio:** Sets the ratio of input signal to output signal for signals below the threshold. Setting it to max (∞) turns the Expander into a noise gate.

• **Attack:** Sets the time (10 to 150ms) it takes for the gate to open once the signal exceeds the threshold.

• **Release:** Sets the time (0.01 to 1 second) it takes for the gate to go from open to fully closed.

Equalizer (8-band):

• **High/Low Pass Filters:** Pass higher or lower frequencies, respectively. You can set the frequency and filter type.

• **EQ Frequency:** Sets the center frequency (20Hz to 20KHz) for each of the 8 bands.

• **Q:** Adjusts the bandwidth of the frequency band (0.4 to 24). A higher Q results in a narrower bandwidth.

• **Gain:** Boosts or cuts the selected frequency band by -24dB to +24dB.

• **Type:** Selects the filter type for the EQ band (Peak, L.Shelf, H.Shelf).

Compressor:

• **Threshold:** Sets the level (-30dB to 20dB) above which the compressor starts to reduce the signal level.

• **Ratio:** Determines the amount of gain reduction (1:1 to 10:1 up to limit). For example, a 4:1 ratio means for every 4dB the input goes over the threshold, the output will only increase by 1dB.

• **Attack:** Sets the time (10 to 150ms) it takes for the compressor to apply gain reduction.

• **Release:** Sets the time (10 to 1,000ms) the compressor takes to return to normal gain after the signal drops below the threshold.

For each module (Expander, EQ, Compressor), there are also Bypass buttons to disable processing and “Flat” buttons to reset all parameters to their default values.

On the “Martrix” tab of the control software, you will see a grid where input channels are listed on the left and output channels are listed across the top. To assign signal flow:

1. Locate the input channel you want to route (e.g., IN02) on the left side of the grid.

2. Locate the output channel you want to send it to (e.g., OUT 02) at the top of the grid.

3. Click the small block at the intersection of that input’s row and that output’s column.

4. When clicked, the block’s background will turn green. This indicates that the audio signal from the selected input channel will now flow to the selected output channel.

You can assign one input channel to multiple output channels by clicking the corresponding blocks in that input’s row. You can also assign multiple input channels to a single output channel by clicking multiple blocks in that output’s column. A signal will not pass if its corresponding block is not activated (green).

On the “Save/Load/Copy” tab in the control software, you can manage presets and channel settings:

Managing Presets:

First, select whether you are working with the “Device” memory or “LocalPC” files.

• **Save:** In Local PC mode, select a preset from the Preset List, then click “Save” to save the preset from your PC to the DLM808’s memory.

• **Load:** In Local PC mode, select a preset from the list and click “Load” to load the preset from your PC to the DLM808.

• **Delete:** In Device mode, select a preset from the list and click “Delete” to remove it from the DLM808’s memory.

• **Recall:** In Device mode, click the “Recall” button to recall all presets in the Preset List.

Copying Channel Settings:

1. In the “Channel Copy” section, use the “Copy from” dropdown menu to select the source channel (e.g., Output CH01) you want to copy settings from.

2. In the “To channels below” section, check the boxes for the destination channels you want to copy the settings to.

3. You can click “Select All” to choose all available channels as destinations.

4. Click the “Copy” button to apply the settings from the source channel to all selected destination channels.

The “System” tab in the control software for your TOPP PRO RT-DRIVE DLM808 provides the following functions:

• **Reset to Factory Setting:** Click this button to reset all setting parameters on the device to their original factory defaults.

• **Change device name:** Click the button under “Device Name” to open a dialog box where you can change the current device name.

• **Password Setting / Lock System:** These functions allow you to secure the device settings.

• **Language:** Allows you to change the language of the software interface.

You can configure the LAN module through its web interface by following these steps:

1. **Search for the IP address:** Use the PC control software (“Matrix System Editor”) to search for the IP address of the LAN module connected to your network.

2. **Open the configuration page:** Open a web browser on your PC and enter the IP address you found in step 1 into the address bar. This will take you to the configuration web site.

3. **Log in:** A login prompt will appear. Use the default password “system” to log in.

4. **Configure parameters:** The web page will show configuration options for TCP, UDP, and UART settings. You can change parameters as needed.

Important: DO NOT change the Baud rate and TCP PORT. You can change any other parameters. After making changes, click “Update” and then restart the device.
