8. The EQ Function Bar . This row lets you choose between GEQ (Graphic) and PEQ (Parametric)
equalizers. You can also Bypass the EQ temporarily to hear the sound with and without the
effects of your tuning. The Reset button resets the channel completely to return the EQ filters
to flat. There are also buttons for the EQ parameters: Band selection, Frequency selection, Gain,
and Q Factor. You can click into these boxes to make fine tuning of each parameter.
9. The EQ Graph : The graph shows you exactly what you are doing to the output signal
going to your amps. In this graph to can Drag-and-Drop the buttons of each EQ filter to make
adjustments of Frequency and Gain. Then make fine adjustments using the PC’s keyboard
arrows. Simply click into one of the parameter boxes and use the keyboard arrows. The active
channel’s EQ plot will always be visible, as will the crossover plot for the active channel. At
the right side of the graph, the color-coded buttons let you choose any other channels
whose plots you want to see as well. The area under the active channel’s crossover will always
be highlighted. This allows you to see at a glance what frequency areas you can work on in
the active channel, and which frequencies fall into a different channel’s crossover range.
10. Output Levels : Output levels allow you to balance the levels of the speakers. Ideally they
should all be near 0dB.
Then you can back off any speakers that are too loud. The main level control can have gain up
to 12dB for low power head units. But you reduce signal to noise ratio when you are set
above 0dB. It is far better to keep the output at 0dB and adjust the amplifiers, if you need
more volume.
