Mic/Line Inputs Processing

The mic/line input processing chain in DSP Configurator is visually represented by a string
of blocks (see figure 35). Each block contains a specific processor or type of processor. For
example, the Input Gain block contains a fader to boost or attenuate incoming signal, the
Filter block contains several types of filters, and so on. Inputs 1 - 4 contain the following
signal chain:
• Input Gain Block
Input Filter Block
•
• Input Dynamics Blocks
Figure 35.
Input Gain Block
Double-click the Input Gain block (as seen to the right) to open the Input Gain
dialog box.
The Input Gain dialog box provides controls to configure
the input gain stage of the input processing path.
Input Name — This name changes to match the default
1
or user defined input name.
Gain Fader — Provides up to 60 dB of gain or 18 dB
2
of attenuation. Click the fader once and press the
<Up Arrow> or <Down Arrow> keys to adjust the fader
up or down in 1 dB steps. Press the <Page Up> or
<Page Down> keys to adjust the fader up or down in
10 dB steps.
dBFS Meter — This meter displays the input signal level
3
in dBFS, ranging from -60 dBFS to 0 dBFS. Once the
signal reaches or passes -1 dBFS (default) or the clip
threshold defined in the Options dialog box (see
Options on page 33), the clip box located at the top of
the meter lights red.
dBFS Numeric Readout — This read-only text box
4
displays the numerical value of the input signal level in
dBFS.
Input Gain Text Field — This text field allows the user to
5
enter a gain or attenuation value in 0.1 dB steps.
Polarity Toggle Button — Inverts the signal polarity of
6
the selected input. When the button displays the black + symbol on a gray field ( ), the
polarity is normal. When the button displays the black - symbol on a yellow field ( ), the
polarity is inverted.
Mute Button — Mutes signal at the input stage, preventing it from going any further in
7
the signal processing chain.
OK Button — Confirms changes and closes the Input Gain dialog box.
8
Cancel Button — Reverts any changes made to the contained parameters back to
9
their states when the current instance of the Input Gain dialog box was opened and
closes the dialog box.
Input Gain Help Button — Opens the Mic/Line Input Gain topic in the
¢
DSP Configurator Help file for further assistance in configuring input gain.
