User Manual

- 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.
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.
