Amplifier Outputs Processing
The amplifier output processing chain in DSP Configurator is represented by a string of
blocks as seen in figure 90. Each block contains a specific processor or type of processor.
The processor chain is as folllows:
•
Amplifier Output Trim Block
•
Amplifier Output Delay Block
•
Amplifier Output Filter Block
•
Amplifier Output Dynamics Block
•
Amplifier Output Attenuation Block

Amplifier Output Processing Chain
Amplifier Output Trim Block
One trim block is available for each amplifier output channel. The trim block functions
the same as the line/AT output trim block (see
Line/AT Output Trim Block
on page 52
information on configuring output filters).
Amplifier Output Delay Block
One delay block is available for each amplifier output channel. The delay block functions the
same as the line/AT output delay block (see
Line/AT Output Delay Block
on page 53 for
information on configuring output filters).
Amplifier Output Filter Block
One filter block is available for each amplifier output channel. This filter block functions the
same as the line/AT output filter block (see
Input Filter Block
on page 36 for information
on configuring output filters).
High-Pass Filter Information
For high impedance amplifiers like the NetPA U 1004-70V/100V and
NetPA U 1002-70V/100V, a fixed high-pass filter is inserted into the output chain of the
amplified outputs. This filter takes up one of the filter slots in the output filter block. This
high-pass filter is inserted to prevent the saturation of the transformer cores in the 70V/100V
speaker chain by low frequency content. The filter corner frequency and slope can be
adjusted. The frequency adjustment has a lower limit of 35 Hz. The filter cannot be deleted,
and the filter type cannot be changed.
