JellyFish™

DK Technologies’ trademark ‘JellyFish®’ display was first launched on audio only meters. It was later developed

to provide the alternative ‘StarFish® display and both included in the PAM PiCo. Both modes provide a picture of

the surround audio field in 5.1, 6.1 or 7.1 channel modes. The display has the front center channel arranged

towards the top with other directions are marked.

The image here shows the StarFish® mode with equal audio on all legs. In JellyFish® mode, the same signals

would produce a circular display. Typical sound fields have energy in a variety of directions and more complex

shapes are created which give an indication of the directions having significant amplitudes.

Surround display size

The default setting places an audio compressor in the drive to the surround display. This provides a relatively

consistent display size from which phase indications can easily be read, which is the primary purpose of the

surround display, amplitude being read from the Bargraphs.

Loudness Bargraph(s)

The Loudness Bargraph enables your loudness readings to be monitored side-by-side with the regular amplitude

Bargraphs.

The specific loudness parameter displayed on the Loudness Bargraph may be set in the Quick setup menu; Input

and Channel order, or in the Advanced Menu; Meter Setup/Loudness Option.

In addition to the loudness reading, Start/Reset buttons for initiating and resetting the overall Loudness Capture

are supplied as well. These are described in detail in the Loudness Setup - Capture section.

Meter Text Readouts

The four Meter Text Readouts allow for completely customized view of four parameters in addition the regular

audio tools.

The custom setup of each of the four Readouts may be set in the Quick Setup menu; Window Text Read-out or

the Advanced Menu; Meter Setup; Windows Text

Reclaim Factor

The Reclaim factor indicates how much you can increase your signal while still staying within your loudness

target.

The Reclaim Factor is essentially the difference between the absolute gated loudness and the dynamic gated

loudness.

By making sure that your material is always above the dynamic gate threshold, the reclaim factor ensures

optimal loudness within the given standards.

Graphical Loudness

Loudness values can be shown graphically against time using the Graph LEQ function.

The Graphical Loudness display allows for up to 3 minutes of loudness to be mapped against time.

The Graphical Loudness view is reached by sliding once to the left of the basic Bar graph display (view 2 Portrait,

View 3 Horizontal).
