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.
