User Manual

- 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.
