CONTENTS

1. INTRODUCTION
Thank you for choosing tm stagetec systems’s Desk 16 Mini – Standalone.
We created the Desk 16 Mini as a high quality paging microphone for Audio over IP networks. It boasts a 2 port
Ethernet switch (1x 1Gb Copper and 1x SFP cage - allowing for various fibre or copper connections), Dante Network
audio, Mic Input, Line Input, Line Output, an inbuilt speaker with volume control and GPIO.
The Desk 16 Mini is powered by PoE (Power over Ethernet) or runs via an external PSU. Redundancy is provided
between both power sources.
The Desk 16 Mini (Standalone) supports up to 8 paging and 8 intercom zones routable over a Dante network.
Please read this manual before attempting to operate your new device to ensure reliable operation for years
to come. For any additional questions that are not addressed in this document, feel free to contact tm stagetec
systems directly.

3. GETTING STARTED
3.1 What’s in the box?
Start by removing the Desk 16 Mini from its shipping carton and check it for possible damage. Also check whether
all accessories have been supplied.
Please be careful while unpacking as sharp edges may cause injuries.
The shipping carton contains:
• Desk 16 Mini
• Gooseneck Microphone
• Power Supply
• Owner’s manual
If anything appears to be missing, please contact tm stagetec systems.
3.2 Installation
Install the Desk 16 Mini in the designated location. Please be aware that the chosen installation location should be
a dry area that is not subjected to extreme heat and has suitable ventilation.
Never remove the outer casing of the Desk 16 Mini under any circumstance. Doing so may compromise electrical
safety and mechanical protection. Be aware that any modification to the unit will void warranty.
3.3 Connections
Powering the device
Please use the supplied power supply to power the device by connecting the phoenix connector to the power input
of the Desk 16 Mini. Be sure to follow all local safety regulations regarding power connections.
Alternatively, if you have a switch with POE (Power Over Ethernet) capabilities you may connect an ethernet cable
from the switch to Lan Port 1 on the Desk 16 Mini to power it.
Sockets/Interfaces
Now you are ready to establish all required connections. The following sockets are provided:
• RJ45 ethernet connection (POE enabled)
• AES In/Out (RJ45) - Not available on standalone model
• SFP cage for fibre or copper SFP
• DB9 Connection for Line level audio and GPIO connections.

4. DEVICE CONFIGURATION

5. OPERATION
The Desk 16 Mini features 16 multifunction buttons. On the Standalone model, the first 12 are assigned to
Dante Transmitters of the device, with each button sending the microphone out a single Dante Transmitter or a
combination of Transmitters. The final 4 buttons are assigned to functions of the panel.

13
When a button is pressed, the panels microphone input is routed out the corresponding Dante Transmitter(s).
When a signal is received on a Dante receiver, the corresponding button/channel will flash, and the signal will be
routed to the built-in monitor speaker.
Volume Down – Decreases the volume of the panel’s built-in speaker.
Volume Up – Increases the volume of the panel’s built-in speaker.
Answer – When a page is received, pressing the Answer key will route the microphone out the corresponding
output to where the signal was received. i.e If a page is received on Dante receiver 2, the answer key will route the
microphone out Dante Transmitter 2.
Up to 8 Desk 16 Mini’s can be used in a simple intercom system, without any external matrix mixers. With an
external Matrix, the system can be scaled further.
