User-Congurable DSP Functions
On the right side of the Control Properties window, in the upper dark grey section, you will see a frequency response graph. Underneath it
are controls for 12 lters. To select a lter, click the button above its white data elds; then either type in your values, use the up-down ar-
rows or scroll with your mouse to adjust the parameters. At the far left is a high pass lter; its low pass counterpart is at the far right. These
lters have three controls: Cutoff Frequency, Type (Bessel, Butterworth, etc.), and Slope. The pair of lters to the inside are shelving lters,
with controls for corner frequency and boost/cut.
The center section gives you control of 8 fully parametric lters, with controls for center frequency, boost/cut and bandwidth in octaves.
When you activate a lter, its button turns green and it appears on the graph – each lter appears in a different color. A solid white line
shows the overall EQ curve. The Bypass All button at the bottom of this section lets you compare ltered and unltered signals quickly.
All lter parameters can be controlled with the scroll wheel on your mouse. Click inside the control eld and scroll to set: Gain,
Bandwidth, Frequency, etc.
Below the EQ section in the left side of the light grey area, you’ll nd controls for the Compressor. The controls – Threshold, Ratio, Attack
Time, Release Time and Soft Knee – are similar to the EQ controls. You can type in values, use the Up/Down buttons, or scroll with your
mouse to nd the values you want.
Under Signal you will nd buttons that set the compressor’s trigger point at Above, At or Below the Knee. When the compressor is
operating, the Bypass button is red and the Gain Reduction meter on the right side of this section lights up. To turn the compressor off or
compare the un-compressed output, click the Bypass button.
To the right of the compression Reduction Meter is the Make-Up Gain control. This control can be used to restore RMS levels of the com-
pressed signal to those expected of the signal pre-compression. It has a range of 0 to +12 dB.
The RHAON input module’s DSP has 340 milliseconds of signal delay available if you are using the 48 kHz sample rate; 170 milliseconds if
you are using 96 kHz.. Use either the up-down arrows or the slider control to adjust the delay time.
