TELOS INFINITY BP-2

Digital Intercom Beltpack

INTRODUCTION

The INF-BP-2 is a dual communication channel digital Beltpack that includes the additional ability
to monitor an auxiliary program audio feed. Unlike traditional analog intercom beltpacks, each
communication channel may be configured to be part of a partyline, group, IFB, or a point to point contact
regardless of the physical connection of the device to the supporting network.

The BP-2 connects over a supporting 100Mbps Ethernet network with 24-bit/48 KHz uncompressed
digital audio carried as Audio over IP (AoIP) using the Livewire+® AES67 industry standard.

The BP-2 is powered by PoE (Power over Ethernet) either directly from the network switch or via an
external PoE source. Additionally, multiple BP-2 beltpacks may be daisy-chained from the network
switch to one another.

Call Indicators (A)

This indicator will light up when a Call message is received.

Call Keys (B, J)

Each channel includes a Call key which is available when either a partyline or a point to point contact is
assigned to a channel. Pressing this key will trigger a call message to other intercom devices assigned to
the same partyline, or the other point to point contact.

Talk Keys (C, I)

Each of the two channels has its own talk key. Pressing and holding the Talk key will activate a “press to
talk” function and the microphone will be muted when the Talk key is released. Pressing the talk key for
one second or less will latch the talk function on until the Talk key is pressed and released again.

Channel Volume Controls (D, H)

Each channel has its own volume control. The volume encoders are located on the side of the beltpack
just below where the keys. Rotating the encoder clockwise increases the volume, and rotating the
encoder counterclockwise decreases the volume. Volume encoders are also used to scroll through
parameters and values when the beltpack is operating in Menu Mode.

Menu Key (E)

The menu key toggles the BP-2 between normal operating mode and the Menu Mode. To enter the Menu
Mode, press and hold this key for 5 seconds. Similarly, to quickly exit the Menu mode and return to
normal operating mode, press and hold the Menu Key for 5 seconds.

Internal Microphone (F)

The BP-2 includes an internal condenser microphone and may be used without a headset if desired.

Internal Speaker (G)

The BP-2 includes an internal loudspeaker and may be used without a headset if desired. The internal
speaker allows the user to hear program audio, or audio from whomever is speaking to them.

Note!

The BP-2 automatically detects when a headset is connected and will change the
listening mode to headset instead of the internal speaker.

Talk Indicators (K)

Each channel includes a Talk indicator next to the Talk key which will light up when the Talk function
is enabled.

Rear Panel

The rear panel of the BP-2 includes the following connectors:

A

B

C

D

Headset (A)

This male XLR connector will be either 4-pin (standard) or 5-pin (option), depending on how the unit
is ordered. The 4-pin XLR supports a single earmuff (mono) headset with microphone. The 5-pin XLR
supports a dual earmuff (dual mono or stereo) headset with microphone.

Program Input Volume control (B)

This encoder directly adjusts the listening volume of the Program Input audio.

Network Connections (C, D)

Two 100-based T network connections are provided. One ethernet port is marked ‘Primary’ for the input
(C), and the other port is a ‘Secondary’ network output (D) for daisy chaining beltpacks.

Note!

The BP-2 required Power over Ethernet (PoE) to operate. If the unit does not power
up, verify that PoE is available, and that the cable is plugged into the primary
connector.

BASIC OPERATION

BASIC OPERATION

Talking

To talk to a desired channel, simply press the “Talk” key. The Talk key operates in one of two modes,
depending on the user’s action:

• Momentary (also called “Push to Talk”): Press and hold the Talk key for longer than 1 second. The talk
function will be enabled (on) if the Talk key is pressed. As soon as the Talk key is released, the talk
function will be disabled.

• Latched: Pressing the Talk key quickly (less than 1 second) will latch the talk function on. Pressing the
Talk key again will disable the talk function.

When the Talk function is active, the Talk LED located next to that channel’s Talk key will be lit.

Calling

To send a call signal to other members of a partyline, press the Call button. The Call LED will light on all
beltpacks of the partyline, including the beltpack which initiated the call signal.

Adjusting the Listening Volume

Each channel has its own individual volume control on the side of the beltpack.
To adjust the listening volume, turn the encoder on the side of the beltpack nearest to the channel.

• Turning the volume control in a clockwise direction (to the right) increases the volume.

• Turning the volume control in a counter-clockwise direction (to the left) decreases the listening
volume.

• To adjust the listening volume of the Program Input, adjust the volume encoder on the bottom of the
beltpack.
