C2N- DAP8 Full Parametric EQ Controls Module 

 

Parametric Equalizer Control Signals 

SIGNAL TYPE 

(D/A, I/O)*

FUNCTION 

Store_PRE 

DI 

On the rising edge of Store_PRE, the current 
filter values will be stored in the preset specified 
by Preset# 

Recall_PRE 

DI 

On the rising edge of Recall_PRE, the filter 
values of the specified Preset#_FB will be 
recalled and propagated to the outputs. 

Recall_PRE1 through 
Recall_PRE5 

DI 

These inputs offer a simpler way to recall a 
preset directly. Preset#_FB will be updated, thus 
Store_PRE will store the last preset recalled.

Filter_Band 

AI 

Each channel has 6 programmable filter sections. 
This variable selects which band (from 1 to 6, or 
0 for no band selected) to operate on. Specifying 
a band will display the current mode, frequency, 
bandwidth and gain for that filter. (Not all 
parameters apply to all filters types.)
