Quick guide
If you just want to get going
If you just want to get going with your new DK Meter right away, here are a few simple steps to get it up and
running.
1. Connect the included power supply or power your meter directly from your computer USB port.
2. Powering up your meter, you will see the on-board quick setup guide –if you want to disregard that,
slide across the three touch buttons from left-to-right (you can always return to the guide later).
3. Connect the DK Meter AES 1 to the appropriate audio output and play audio.
4. You will now see the default meter view in stereo or surround sound depending on your model and
options (fig xx). This view includes four main sections:
Meter Text Readouts –Integrated Loudness, Reclaim factor, Loudness Range and Peak Level
(true peak)
Digital PPM –Showing True Peak
Vectorscope/GonioMeter –Showing sum/difference content
Phase Correlation –showing phase information
For more information on the individual tools, please refer to the ‘display tools and options’ section of this manual.

Basic Operation
Mounting your DK Meter
The DK Meter is supplied with an adjustable mounting bracket. The top piece is
mounted onto the DK Meter with the two included screws, while the desktop
piece is mounted with four screws.
Additional fixing options and mounts are available from DK-Technolgies.com or
from RAM on http://www.rammount.com .
The included model number is: RAP-B-138U
Power Supply
The DK Meter comes with a plug-top power supply with a USB outlet. If being
used in conjunction with a computer or USB hub, any conventional USB-A outlet
with the standard USB 5 volt supply may be used instead of the included power
supply unit.
This elegant feature not only makes the DK Meter easier to bring along, but also
conveniently allows the DK Meter to power up with the relevant computer of your
setup.
Navigation
The general navigation on the DK Meter is achieved through the three capacitive touch sensitive buttons below
the screen.
Each touch button corresponds to the on-screen button and dynamically changes name as relevant.
In addition, swiping across the three buttons from left-to-right or vice versa, allows you to change the overall
meter view or selected menu.
Note: When fixing the mounting plate to the rear of the meter, use only
the screws supplied –damage may be caused by using longer screws, or
different mounting back plate.

Sliding Windows and Views
The sliding function described above allows you to easily move from one meter setup to another, as well as
entering the background Quick setup, preset and Setup menus. Here is a quick overview of the immediate
windows that you can slide between:
In every DK Meter there are four basic meter views in addition to ‘Preset and Quick Setup’ Menu and the
‘Advanced Setup Menu’. The three meter views are; PPM+Vectorscope, PPM Loudness history and Horizontal
Loudness history and Horizontal Bargraph. Additionally, the DK4 meter features another two landscape views
which may be obtained for DK1, DK2 and DK3 as software upgrades i.e. the ‘MSD Landscape Views’ and the FFT
analyzer.
See more details about the individual meter views in the Meter View Section of this manual.
Menu Navigation
When inside a menu (Quick setup or Advanced setup), the three touch buttons become your navigation. The left
most button moves the cursor up, the center button moves the cursor down and the right most button becomes
a ‘select’ function.
At any point is it possible to ‘slide’ across the buttons to exit the current menu.
In several of the menus, a folder structure has been designed to hold the many parameters and functions of the
DK Meter.
To open or close a folder, move the cursor on top of the folder and press ‘select’. You are now exposed to the
folders inside, including potential sub-folders.
Tip: Selecting an empty line and hitting ‘Select’ will close the current folder.

The Preset and Quick Setup
When powering up your meter for the first time, the ‘Preset and Quick Setup’ menu will be shown as the first
display.
The Preset and Quick Setup menu, allows for a simplified and fast way of setting up you DK Meter. More
advanced settings and functions are edited in the ‘Setup’ menu reached by sliding from right to left.
The Quick Start Guide will give you a few basic tips on operation and setting up your meter.
Let’s walk through the different folders:
Here are the four simple steps to follow to set your
meter up in a few minutes:
Step 1 Preset List –Select the preset you
want to work with
Step 2 Input and Channel Order –Select
your preferred input and choose your
desired Loudness bar-graph
Step 3 Scale and Loudness Setup –Select
your Scale and Loudness setup of choice
Step 4 Meter Text Read Out –Define what
four parameters you want to see on the Meter
Text Read Out.
Step 1- Preset List
The DK Meter holds a list of presets that allows you a fast starting point,
as well as showcasing some of the different tools included in the Meter.
Any of the presets can be edited to become a custom user preset.
Selecting a preset is as easy as moving the cursor to the desired preset on the list and hitting the ‘Select’ button.
DK Meter always has a preset selected and changes are instantly stored upon exiting to the Meter view, be it;
meter setup, background parameters and display appearance.
Dynamic preset naming
When advancing in the Quick Setup, the selected preset name will dynamically reflect your choices.
The dynamic preset name includes the following information:
Input Source –channel count and Order –Loudness Setup - Scale
Note: The power-up showing of the Quick Start Guide may be disabled by unchecking the ‘Show this panel
on power up’ parameter (the change is stored upon exiting to the meter viewings).

Dynamic Preset Example
The naming of a preset may be customized in the ‘Advanced Setup Menu’ under the Audio Global/Preset Folder
(see more in the ‘Setup Menu’ section).
Step 2 - Input and Channel Order
The Input and Channel Order section allows you to easily select both your
preferred input source and the order of the incoming channels.
The list of input and channel order only displays inputs and channel setups
allowed by the current meters specific hardware and software configuration.
More advanced input and channel routings may be accessed in the Advanced Setup Menu.
The following inputs may appear depending on your specific Meters ability and interfaces:
Analogue
Digital
De-embed
All interfaces may be selected as 2.0, while only Digital and De-Embedded allows for 5.1 setups.
5.1 setups allow for two different channel orders:
LRC –corresponding to the EBU channel order: Left, Right, Center, LFE, Ls, Rs
LCR –corresponding to the SMTPE channel order: Left, Center, Right, Ls, Rs, LFE
Choosing ‘User Def’ will make the meter fall back on the settings of the more advanced ‘Setup’ menu, allowing
you to tailor input source and channel order in more advanced ways than those offered in the Quick Setup.
Step 3 - Scale and Loudness Setup
This menu allows you to define exactly what scale and specs your bar graphs
should perform to.
Select the desired scale by moving the cursor in place and hit ‘Select’.
The scale list includes:
IEC 268 I
BBC –IEC 268 II
IIB –IEC 268 II
DIN
SMPTE VU
FBTV –DIN
NBC –Ultra VU
LEQM –RMS LEQ
ITU –RMS LEQ
DMU1 –DMU1630
DMU2 –DMU1630
40A –Dorrough
40C –Dorrough
EBU –IEC 268-18
Web Peak
PPM4 –Loud 10
Any scale will be applied to the chosen Meter view.
