Parameters can be changed on the properties panel in three ways. The faders can be drag and dropped to a new value, the value
can be scrolled up or down using the up/down buttons to the right of the value windows, and finally values can be directly typed
into the value windows. The response graph will adjust according to the new values and vice versa, adjustments in the graph
window will be reflected in the fader positions and values in the properties panel.
The High and Low pass filters only has a single fader for the corner frequency. This may be adjusted in exactly the same way as
the faders for the PEQ's. The 'Type' drop-down for the high pass offers two types of filter and slopes from 24dB to 48dB per
octave, for the low pass Butterworth, Bessel and Linkwitz Riley are available with slopes from 6 to 48dB per octave. The high
pass for the main out is 48dB per octave Linkwitz Riley only.
To summarise, there are four ways to adjust filter parameters;-
1. Click and drag on the graph
2. Click and drag the properties faders
3. Use the up/down value buttons in the properties section
4. Directly type values into the value boxes.
Whilst this might seem over-versatility, it is intended to offer several options to suit the way that the system is being operated.
If adjustments are being made with the Lenovo tablet PC in tablet mode with the stylus whilst walking around a venue, certain
options may be easier to use than if you were sitting at a desk with a mouse plugged in to the PC.
The Main out also has a limiter to protect the connected mid-top cabinet from excessive power. This is located at the top right
of the EQ window above the properties section;-
The Limit is the threshold point in dB and can be adjusted from -18dBu to +2dBu. The Attack time can be adjusted from 0.3ms
up to 90ms and the release is a factor of the attack time, either x2, x4, x8, x16, x32 or x64.
