1.2 About Tango

TANGO - Networked Communications Platform

The Tango TNG-200 is Riedel’s first fully-networked platform based on the AES67 and AVB standards. With its

own dedicated Intercom application, it can be turned into a cutting-edge and flexible solution for a variety of

communications scenarios.

Riedel’s Tango TNG-200 offers powerful processing capabilities, 2 integrated Riedel Digital Partylines, 2 AES67

and AVB compatible ports, 2 Ethernet ports, 1 option slot, and redundant power supplies. Tango TNG-200 is

1.5 RU high and features a low mounting depth and a low noise design. All Riedel current and legacy

Intercom panels, including the new 2300 Smartpanel, are fully compatible with Tango.

The sunlight readable, high-resolution, full color TFT display ensures perfect readability at all times,

extending the range of possible applications and providing maximum ease of use. The intuitive front panel

controls enable users to easily recall presets and adjust audio levels.

PULSE

Intuitive Configuration Software

Riedel’s Pulse is the configuration software for the Tango TNG-200 platform. It enables access, setup and

control of any aspect and function of the Tango TNG-200 platform and its installed applications, combining

intuitive handling features such as drag and drop as well as 3D views for easy programming.

The Pulse user manual is a separate document and available on the Riedel Website.

http://www.riedel.net

Intercom Application

Riedel’s powerful Intercom Application for TNG-200 turns the Tango platform into an efficient Intercom

system, enabling users to tailor the system according to their needs including matrix size, starting with a 40 x

80 system. The software offers full backwards compatibility with the whole range of Riedel control panels

and accessories. It is configurable by Pulse, Riedel’s Intuitive configuration software for the Tango TNG-200

platform and its applications.

Figure 1: Tango system overview (example)

1.3 Audiopatch

All panel types that are operated with a Tango with the firmware version 1.0 and the Pulse software version

1.0 are preconfigured with static audio patches, which cannot be modified. This functionality is enabled in a

future version of Tango and Pulse.

There are two audio patches preconfigured that can be toggled by the headset key on the panel.

The following tables and figures are illustrating the preconfigured audio patches.
