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.

- 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 6

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.
