AVT Magic TH6

The Olympic Channel is a new, ground-breaking digital platform where fans can experience the power of sport and the excitement of the Olympic Games all year round, and is available worldwide via mobile apps for Android and iOS devices and at olympicchannel.com

Test Bench Made by: Yeray Alfageme, Broadcast Systems Engineer at OCS (Olympic Channel Services).


The Magic TH6 unit by AVT is a hybrid telephone system that combines POTS or VoIP interfaces on the telecommunications side, and analogical and digital interfaces on the audio signal side, all in one unit, making it possible to operate with either of these connections interchangeably.


Specifically, it has up to 6 analogical POTS lines for conventional telephony or a VoIP interface through its LAN port with the availability of a further 6 lines when configuring it towards our own PBX. If we choose the VoIP option, our PBX permitting, we can benefit from HD-Voice with increased bandwidth of our call up to 7 KHz, allowing us to use the unit as a transfer system, or even for commentators’ positions if need be.


The unit is rugged and does not feel like an “empty box”, like similar units on the market. The case is not weak, and the cabling and internal circuits are correctly fastened inside, making it perfect for uses in OB Vans or more complex environments than in permanent studio installation.

The rear side is straightforward and easy to connect. All the connectors of the same type are grouped together, which permits connecting all our communication lines, controls, either LAN or through tallies, and our audio connections easily. But if I were to nit-pick, I’d say it doesn’t have a redundant power supply, which may not make it suitable for high-availability environments.


In addition to the 6 POTS lines, if we have acquired this model, and the LAN control, Tally and series connections for the keypad, we find 4 XLR connectors for the two analogical inputs and outputs, as well as a 15-pin connector for the two pairs of AES. We also find another two RJ-11 ports, the same as those of the POTS lines, but here, they offer the possibility of connecting two headsets for smaller operating environments where we don’t have the benefits of a complete intercom system.


On the front, we see a set of 7 LED indicators for power, alarm and the 6 available communication lines. Its back-lit LCD screen with 4 effective lines is more than sufficient and marks a great difference compared to traditional models made by other manufacturers. A pair of buttons to interact with the screen and a navigation spider with a standard numeric button pad for telephone systems is on the right.


The navigation and use of this panel are limited but sufficient for environments such as mobile units where the connections are permanent during the entire production, or in simple environments where, with the help of the headset, we can operate the equipment directly from its front panel without needing any software.
