computer. This program is sometimes referred to by the shorter name of

Windows Setup Program: (Velodyne recommended interface) Software that runs on a Windows

Windows interface. The software is used to:

- Initiate Self-EQ, Auto-EQ

and Manual-EQ optimizations

- Display the subwoofer’s frequency response curve

- Display the parametric filter curves

- Save and open Digital Drive

files with subwoofer’s settings and for Manual-EQ only, the frequency response

curve that results from these settings

- Save settings to the subwoofer’s memory

• TV Screen Display and Remote Control Commands: This combination is often referred to by the shorter name of

TV Screen interface because settings and command choices are shown on your TV screen. The TV screen interface and

remote control can be used together to:

- Control and display preset EQ and parametric filter settings

- Initiate Self-EQ, Auto-EQ

and Manual-EQ optimizations

- Display the subwoofer’s frequency response curve

- Display the parametric filter curves

- Save settings to the subwoofer’s memory

MANUAL ORGANIZATION

You need to only use one interface for optimization or viewing of settings and frequency response curves. We recommend the Windows

interface as it is usually much easier to connect your subwoofer to your computer than to your TV screen. Also, the Windows interface

allows you to see the parametric filter curves and save settings to files on your computer. These features aren’t available with the TV

screen interface. Because you only need to use one interface, skip to the part of this manual that covers the interface you want to use:

• Part One - Windows User Interface for Optimization (Recommended Interface)

• Part Two - TV Screen User Interface for Optimization

Each diamond represents one of the eight parametric filters. The small number by each indicates the EQ number of the

parametric filter that diamond represents.

The filters are numbered 1 to 8 from left to right.

- The green line is the curve for a single parametric filter.

- The blue line is the summation of all parametric filter EQs.

- After one complete sweep tone, the frequency response updates.

- You can use the mouse to grab and drag the filter to a new frequency and level. Moving the diamond up and down changes the

level of boost or cut. Moving it side-to-side changes the frequency of the selected EQ filter.

- Once a parametric filter’s EQ graph has a peak or dip, you see a horizontal line with small diamond handles appear through the

latest filter at the maximum or minimum level. Moving one of the diamonds at the end of this line towards the filter center diamond

raises the filter Q, narrowing the bandwidth. Moving it away from the filter center diamond widens the bandwidth lowering the Q.
