Hardware
MP-16 and DS-16 Front Panels
The Telos Infinity MP-16 is a 19inch 1RU, 110mm (4.3 inch) deep sturdy rack mounting metal case. DS-16 is a Desktop Station constructed from a combination of a metal chassis and plastic trim parts. All operational controls are accessible on the front Panel and some configuration is possible from the front Panel menu.
Mic Selection Switch (A)
Microphone Input (B)
A front Panel socket supports an optional screw-in gooseneck microphone. The adjacent switch enables or disables the front Panel gooseneck microphone.
TRS Jack Micropohone Connection
Menu Key (C)
The Menu Key puts the unit into Menu Mode. When operating in Menu mode, the Contact Keys change function to display menu options and parameters, which are user adjustable.
Shift Key (D)
The Panel is capable of supporting more than 15 contacts. When more contacts are programmed to the unit than it can display on the front Panel at one time, the additional contacts may be Grouped into different layers, or Shift Pages. The Shift Key scrolls through the different Shift Pages (layers) of contacts, only accessing pages that have been assigned a contact until finally returning to the first page at the end of the cycle.
Main Output Volume Control (E)
The top rotary encoder on the unit provides the volume control function for the main output (either the internal speaker, headset or the rear Panel output when configured to output incoming talkback). Rotating the encoder clockwise increases the volume. Rotating the encoder counterclockwise decreases the volume. Pushing the encoder in mutes/unmutes the listening function.
Internal Speaker (F)
An internal speaker is fitted within the Panel, allowing the unit to be used without a headset. The speaker is mounted into a sealed baffle, designed to optimize speech reproduction.
Aux Output Volume Control (G)
The bottom rotary encoder provides the volume control function for the Auxiliary output on the rear Panel. This functions in the same manner as the Main Output Volume Control described above.
Home Key (H)
The Home Key acts as an “escape” key and returns the unit to the upper operating level and to the 1st shift page, from wherever the unit may be in the menu or shifted page structure.
Last Caller Key (I)
The bottom right key of the unit displays the last contact that has called the Panel and keeps a list of the last 20 incoming callers received. The Last Caller ‘stack’ can be cleared by lifting the key for 5 seconds.
Contact Keys (J)
Each of the contacts has its own key. Pressing the key down enables the Talk function and pressing the key up enables the Listen function or answers an incoming call.
Headset Selection Switch (K)
Headset Input (L)
All Telos Infinity products feature a standard 4-pin XLR chassis male connector (where fitted) for headset connection. 5 pin variants may be available at a later date or via special order following consultation with the factory.
4-Pin XLR Connections
MP-16 and DS-16 Rear Panels
The rear Panel of the INF-MP-16 and DS-16 consist of the following connectors:
Analog Inputs (A)
Two female 3-pin XLR connectors (where fitted) are provided. They can be configured to accept either a mono microphone input (left XLR only), or as a stereo line input. Phantom Power is supported when the input is configured for microphone use. When used in mono microphone mode, the right XLR (where fitted) is disabled.
XLR Input Modes
XLR Input Connections
Analog Line Outputs (B)
Two male 3-pin XLR connectors (where fitted) are included which provide a +4 dBu line level output. They can be configured to output either an audio source (an input to Infinity), assigned from the Livewire+™ AES67 network, or the talkback/ comms audio sent to the internal speaker. It is also possible to assign a combination of the two when the external XLR connectors (where fitted) are set in dual mono mode.
XLR Output Modes
XLR Output Connections
GPIO (C)
A DB-15 socket connector provides 5 GPIO Inputs and 5 GPIO Output pins(where fitted). The pinout is consistent with other Telos Alliance products. GPIO connections are user-assignable.
DC Input (D)
A secure screw-lock +12 VDC input is included. This can be used to provide a redundant power source (recommended) or primary power if a PoE source is not available.
DC Power Connector
Network Connections (E)
Two 1000-based T network connections are provided. One Ethernet port is for the input and PoE, and the other port may be configured as a separate control or a network “through” for connecting to Expansion Panels.
Primary (with PoE)
Secondary Loop Through
Headset Input (F) DS-16 Model Only
All Telos Infinity products feature a standard 4-pin XLR chassis male connector (where fitted) for headset connection.
