INTRODUCTION
Before you begin…
Thank you for purchasing one of the DK Meter family members.
With the DK T7 you are well equipped to meet the growing challenges within Audio and Loudness metering.
The DK T7 complies with all major Broadcast loudness standards and delivers outstanding
metering precision and clear read-outs, not merely on Loudness, but across the full range of audio metering
tools.
The DK T7 toolset makes it application-fit for any audio and loudness setup in broadcast, film & post production
as well as live transmission and recording.
With the clear DK T7 readout and compliance in your line of sight, you are always safe and sound.
About this manual
This manual will provide you with a quick overview of the DK T7 operation, tools and options, as well as an in-
depth look at the more advanced parameters and facilities of DK T7.
The manual covers the following product models:
DK T7
DK T7 Stereo
PT0T7
Software versions: 01052014
Happy reading!
Please note: DK-Technologies reserve the rights to change the content of this manual at any time. The latest
revision of this manual can be downloaded from: www.DK-Technologies.com
DK T7 vs. DK T7 Stereo –The Difference
The two models are very closely related and this manual covers both versions of DK T7 / Stereo.
The sheer difference is that while DK T7 includes SDI I/O and 8 ch. AES I/O, the DK T7 Stereo is limited to 2 ch.
of AES I/O and no SDI.
This means that any functionality and comment of this manual related to more than 2 inputs channels or SDI
signals is only relevant for the regular DK T7.
The product is referred to as DK T7 throughout this manual.

Basic Operation
Touch Zones & Navigation
The DK T7 is a multi-touch sensitive device allowing for both slides, tap and
Press & Hold functions.
The basic operation of the DK T7 is based on simply touch the area of the screen
that you would like to interact with.
Touching
Touching a specific area, will call up the relevant menu points and allow you to
alter settings in an instant.
Exiting a menu is always done by hitting the top menu bar on the left hand side.
Selecting a Parameter
When inside a menu, there are several ways of selecting a specific parameter.
1) Touching the desired parameter directly. This also used to open/close folders inside the menu structure
2) Sliding the menu until your parameter is in sight by simply sliding your finger up/down the screen on
the mid-left hand side of the menu
3) Moving the cursor to the desired position by sliding on the far right hand side of the menu.
Auto Storing Feature in the DK T7
The DK T7 features an ‘Instant Store’ facility that constantly stores any parameter change to the current preset.
This means that there is no need for manually storing presets, as your changes take effect at the moment of
performing them

Meter Views –an Overview
This section gives you a quick overview of the different views available in the DK T7.
StarFish View
The StarFish view, builds on
the heritage of the famous DK-
Technologies MSD meter range
and features a Vectorscope
alongside a bargraph section
allowing for both level and
loudness views. In addition, the
four text readouts are
displayed on the upper right
section of the screen.
In addition to the regular
meters and read-outs, the
StarFish view features a Time
code display below the
StarFish®, which allows you to
follow either the internal time-
code used during Loudness
automation or external SMPTE time code.
Moving Coil Mode
DK T7s StarFish view offers and alternative setup showing Moving coils
rather than bargraphs. There are two moving coil modes; ‘regular’ and
‘dual’ The ‘Moving Coil dual ’ mode allows you the ultra-wide Moving Coil
instrument displaying left and right channel in the same instrument,
while the regular mode will give you a separate moving coil instrument
for each input channel.
Picture Preview
The Picture preview confidence monitor, enables you to quickly monitor
the picture from the incoming SDI stream (3G/HD/SD) to ensure that you
are monitoring the correct stream. The Picture preview field may be
turned on/off or ‘dragged’ in position and resized to your liking.

9 | P a g e
Graphical LEQ
View
The Graphical LEQ view, allows
for several different
simultaneous views.
On top of the four standard text
readouts and phase meter, it
features level bar-graphs
adhering to the defined scale,
while the dual Loudness bars are
referring to the defined loudness
scale. In essence, this means
that two independent scales are
viewed at the same time.
Furthermore, the Loudness level
is plotted against time as a
graphical track on screen,
allowing for a historical view.
Loudness may also be logged via the DK Logging application against either internal time or external SMPTE time
code (free of charge).
Additionally, four extra text readouts may be defined on the top right section of the screen.
FFT 1024 View
The FFT view, simply features a
1024 band FFT spectrum
analyzer.
The FFT analyzer may be used
to check the spectral content of
individual channels in great
detail. This allows to check for
unwanted noise signals high and
low, as well as review the
spectral balance of your source
signal.
The FFT features detailed cursor
and Zoom functions allowing
ultra high precision spectral
review.

& Audio Routing
Understanding the Basic Signal flow of the DK T7
As you are probably already aware, the DK T7 is a quite complex product with a lot of different signal routing
sources and destinations i.e. SDI, AES, Analogue as well as internal signal sources with destinations of
Bargraphs, Text Readout, StarFish, FFT, Loudness measurement and Downmix possibilities.
In order to simplify the overall routing, the DK T7 features a semi-automated routing scheme based on the
different signal source Types.
This allows you to simply select the appropriate source and type/role for your bargraph meter and DK T7 will
automatically define the rest of the routing.
For the same reason, it is very important for you to set up the bargraphs correctly, as this will define the rest of
the metering setup.
There are three important parameters to be aware of in setting up your Bargraph meter:
-Source Select –touching the top legend bar of the meter
-Source Label or Naming –touching the top legend bar of the meter
-Defining the Type of your source –touching the actual bargraph element
Reading through the below # 1, 2 and 3 sections will give you an understanding of the basic setup parameters.
