AES Lock Indication
The AES enabled DK Meters feature an AES lock indicator, allowing you to instantly confirm that the meter is
locked onto the incoming signal. When clocking to an incoming AES signal, AES1 needs to be fed the master
clock. Given that a valid clock and lock is achieved, AES1 will light up green.
The corresponding AES inputs will be green when valid data is received in sync with the incoming clock on AES1.
Goniometer – Vectorscope
The Goniometer is automatically chosen when StarFish™ or
JellyFish™ are enabled and only 2 channels are routed to
the Bar-graph section (please the Matrix section for further
details).
The Goniometer or Vectorscope, displays phase and
amplitude information on the Left and Right input channels.
Phase correlation
When the Goniometer, StarFish™ or JellyFish™ are selected, the left most part of the display is a phase bar-
graph with purple graticule lines. This displays information on the main left/right inputs, with the factory supplied
default for this being the first AES input. Other signals can be chosen using the internal matrix.
Audio meters are rarely used to display pure sine waves and the term “in-phase” is applied here meaning a
signal where the mono sum is equal to or greater than the higher of the left and right signals. “Out of phase” is a
signal where the mono sum would be less than the higher of
the left and right signals.
Signals which are predominantly “in phase” have a green
marker in the upper half of the range. Fully correlated signals
such as double mono read on the +1 mark. Signals which
are “out of phase” are shown with a red marker in the lower
half of the range.
With no input, with only the left or right driven or with
correlated mono but with a 90 phase shift, the marker
position is the halfway point with the upper section of the
marker green and the lower part red.
StarFish™
The StarFish™ is the development in the JellyFish™ surround audio
display, developed by DK-Technologies many years ago. It provides a
picture of a 5.1 surround audio field. The display has the front center
channel arranged towards the top with other directions as marked.
The image here shows the StarFish™ display with equal audio on all
legs. 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. Unlike the earlier JellyFish™
display which with the same signal would have shown a circle, the
StarFish™ takes into account the summation occurs when there is coherent (in-phase) content between legs
