●Screen expansion and legends
On the left-hand side of the graphical screen are four icons to help precise settings. The top Arrow icon expands the graphical screen to the size of the window.Clicking this icon again from the expanded screen expands it to the full display size. In either of the expanded settings, clicking the X-icon at the top left will collapse the graphical area to the default setting.

The T(ext) icon will place the frequency, Q and gain values of each EQ and filter setting in the graphical screen. 

For very accurate settings of EQ or filtering you can click the Looking Glass icon.

●Delay, limiter, compressor
Settings for channel delay, limiter (-48 to +24 dBu) and Limiter release rate (10 to 100 dB/s) settings.Plus a button to enter the rms compressor menus.Channel delay can be set in a variety of distance or time units from the drop-down list.

●Compressor settings window
Clicking on the compressor button brings up the compressor menu.
In the compressor menu you can set the parameters of the rms compressor.You can set the threshold, attack, hold, and release time, the compression ratio and the make-up gain.Next to the controls is a VU meter that also displays the gain reduction (GR). Be sure to use the ‘Back’ button to return to the output menu.
