DSP Control

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.

DSP Control

- Release

Click the control to set the amount of time for the gate to go from open to fully close. It can be set from

0.01 to 1 second. Note: A fast release abruptly cuts off the sound once it has fallen below the threshold, A slower release smoothly changes from open to closed, much like a slow fade out. If the release time is too short, a click can be heard when re-open the gate .

- Bypass

Click Bypass, it will illuminate red, all input signals will bypass control of Threshold, Ratio, Attack and Release to flow to next block, these parameters can not be adjusted.

- Flat EXP

Click this button to flat all set parameters to be default.

- Polarity

Click this button to invert the phase of the selected channel's signal (to alter the phase by 180°). If the phase reverse is active the button will illuminate. The Polarity control can be used to correct audio signals which are out of phase as well as to cancel/reinforce each other.

3). Equalizer

In this area, you can adjust parameter of Equalizer(EQ) , the curve in coordinate will change with parameter’s change. EQ can compensate and correct frequency characteristic, through which to make its frequency response characteristic curve to be more smooth and straight. On DLM808, you can adjust 8 band EQ.

- High Pass Filter

This is a high-pass filter. It can pass higher frequencies. When set to its lowest position, the filter is off. Type indicates the filter’s type that you selected, different type means different shape and different filter frequency range.

- Low Pass Filter

This is a low-pass filter. It can pass lower frequencies. When set to its highest position, the filter is off. Type indicates the filter’s type that you selected, different type means different shape and different filter frequency range.

- EQ Frequency

Click the control to set the center frequency of the equalizer's Low/Low-mid/High-mid/ High band separately. The center frequency is the middle of the pass-band between the lower and upper cutoff frequencies which define the limits of the band. The center frequency can be set from 20Hz to 20K Hz.

- Q

Click the control to set the Q for the Low/Low-mid/High-mid/High band separately. The Q is the ratio of the center frequency to the bandwidth. If the center frequency is constant, the bandwidth is inversely proportional to the Q, which means that if you raise the Q, the bandwidth will be narrowed. It can be adjusted from 0.4 to 24.

- Gain

Click the control to set the gain attenuation or boost at the center frequency for the Low/Low-mid/High-mid/High band separately. It can be set from -24 to +24 dB. When Gain is 0dB, center frequency and Q are all invalid.

- Type

To select current filter type of current EQ, option is Peak/L.Shelf/H.Shelf.

- EQ Bypass

Click this button to bypass all signal to next block, if EQ bypass function is active the button will illuminate. If it is not active,signal will be processed at this block and then flow to next block.

- Flat EQ

To flat all setting parameters to default.

DSP Control

4). Compressor

In this area, you can adjust parameter of compressor. Compressor will compress signal that higher than threshold with specified ratio, then output it. The curve in coordinate will change with parameter’s change.

-Threshold

Click the control to set the compressor threshold for selected channel. If amplitude of an audio signal exceeds a certain threshold, the compressor will reduce the level of this signal with specified ratio; If amplitude of an audio signal is lower than this given threshold, compressor won’t work, signal will flow to next block directly.

If setting ratio to “+∞”, compressor will be limited.

Threshold can be set from -30dB to 20dB.

- Ratio

Click the control to set the compression ratio for selected channel. The ratio determines the amount of gain reduction. For example, a ratio of 4:1 means that if input level is 4 dB over the threshold, the output signal level will be 1 dB over the threshold. The ratio can be set from 10:1 to 1:1 until limit.

- Attack

Click the control to set the compressor's attack setting for selected channel. The attack setting is the period when the compressor is decreasing gain to reach the level that is determined by the ratio. You can set the attack from 10 to 150 milliseconds.

- Release

Click the control to set the compressor for selected channel. Release sets the length of time the compressor takes to return to its normal gain once the signal level drops below the threshold. Release can be set from 10 to 1,000 milliseconds.

- Bypass

Click this button to bypass all signal to next block, if compressor bypass function is active the button will illuminate. If it is not active,signal will be processed at this block and then flow to next block.

- Flat COM

To flat all setting parameters to default.

- Delay

Delay here can engage and disengage the delay function for selected Channel. Move the slide below it to set delay time. Only if delay function is active can set the delay time. If Bypass beside it is enable, the parameter can not be adjusted.

5). Current input channel selection

Click channel button 1-8, corresponding background LED will light, which means current channel is selected, you can set parameters on this channel.

6). Input channel mute control

Click it, the background LED will light, which means it enable mute function on current channel.

7). Input channel Meter control

Select the block and slide it to adjust current channel’s volume.

8). Input channel Meter dynamically indication

DSP Control

4. MATRIX

1). Assign of input and output channels

In this area, there are many small blocks, click one block, its background turns green, audio signal flow from left input channel to top output channel; while the signal won’t go through any channel if it is not active. Below figure gives an example:

a. Click the block as a marked, its background turns green, means that signal input from channel Local 02 will be assigned to output channel Local

02. But the input channel Local 02 wouldn’t be assigned to other output channels because there is no other block activates. b&c. Click the block as b&c marked, their background turn green, means that signal input from channel Local 03 and Local 04 will be assigned to output channel Local 03. Other channels that inactive won’t be assigned to any other output channel. d&e. Click the block as d&e marked, their background turn green, means corresponding input channel signal will be assigned to corresponding output channel. And so on...
