Regardless of the edit mode selected, there are two means to enter edit mode: pressing the Edit button or pressing
any DSP block button. Use the < SELECT > buttons to navigate to the top line of any edit screen, and the Value
Up and Down buttons to navigate to any other Edit screen. As a short-cut, press a DSP block button to jump to the
last selected screen of said block and navigate as above to reach the desired screen.

5.9 DSP Parameters

The following section is a detailed description of every DSP parameter available in the Dx46; grouped by DSP block,
in order of the signal flow of the Dx46.

Not all parameters may be accessible in every preset and, depending on the configurations set by the contractor/
installer, not all presets and/or preset values may be available for editing. Changes to preset availability, parameter
availability and preset value ranges can only be set using the IRIS-Net application.

When configuring a PA or loudspeaker system, there are a variety of different scenarios that will require time align-
ment or delay compensation. Some of the different scenarios are:
• Delaying a set of loudspeakers to act as under-balcony fills or delay towers in a concert PA
• Aligning a PA system to the sound source on a stage, or aligning the "tops" to the "subs"
• Timing correction to compensate for the offset acoustic centers of individual transducers within a loudspeaker cabinet
• Delay offset for one or more loudspeakers in a cluster to improve coverage and overlap effects
Some applications will only encounter a few of these needs, while others will encounter all of them, such as in a
theater with a center cluster of horn-loaded loudspeakers, subwoofers, and under balcony delay speakers.
With other DSP products, a designer must make use of only one or two delay sections, which means that a designer
must carefully think about how to calculate delays, how to add offsets to individual channels so that delay section
can perform multiple tasks. This can result in a confusing DSP structure and more potential for delays being adjusted
improperly. The Dx46 provides dedicated delay sections to perform each of these delay scenarios independently,
which provides easier setup, adjustment and programming.
SIGNAL GENERATOR
The integrated signal generator of the Dx46 can generate following signal types:
• Sine signal
• White Noise
• Pink Noise
