Introduction

The Model 381 On-Air Beltpack offers a unique combination

of audio resources to directly support a complete broadcast

“stand-up” on-air position. Using Dante® audio-over-Ethernet

technology, the unit provides main and talkback output chan

nels, talent cue (IFB) input, and sidetone capabilities, as well

as essential user controls in a compact, portable package. The

Model 381 is compatible with the Dante Domain Manager™

(DDM) software application and is AES67-compliant for

direct integration into many contemporary networked audio

applications.

Optimized for broadcast sports and live entertainment events,

eSports, news-gathering, and streaming broadcast applica

tions, the Model 381 allows incredibly simple deployment while

maintaining “pro” audio quality and an intuitive user experience.

With just a Power-over-Ethernet (PoE) connection, a dynamic

or phantom-powered microphone, and a pair of headphones

or an earpiece, the unit will be ready for “on-air” deployment.

The STcontroller software application is used for configuring

operating parameters including microphone preamplifier gain,

P48 phantom power, headphone signal routing, sidetone opera

tion, and talkback button action. The Model 381’s audio quality

is excellent, with low distortion, low noise, and high headroom.

Careful circuit design and rugged components ensure long,

reliable operation.

Applications

The Model 381 provides an “all-Dante” solution for one on-air

talent location. Two Dante audio input channels supply the user

with their talent cue (IFB) signals. Should the cue signal be

“mix-minus” an integrated sidetone function can provide the

user with a microphone confidence signal. Two Dante audio out-

put channels, one designated as main (for “on-air” use) and the

other talkback, are routed via the associated local-area network

(LAN) to inputs on Dante-compatible devices. A pushbutton

switch, located on the Model 381’s top panel, provides a combi-

nation talkback and “cough” function. When talkback is not ac

tive audio associated with the microphone preamplifier is routed

to the Dante main output channel; the Dante talkback

output channel is muted. When the talkback function is

active audio is muted on the Dante main output channel and

activated on the Dante talkback output channel. The audio

switching is performed in the digital domain and is virtually

“click-free.”

Setup and Operation

Set up and operation of the Model 381 is simple. An ether-

CON® RJ45 jack is used to interconnect with a standard

twisted-pair Ethernet port associated with a PoE-enabled

network switch. This connection provides both power and

bidirectional digital audio. A broadcast headset or handheld

(“stick”) microphone can be directly connected to the unit’s

3-pin XLR microphone input connector. This input is compat

ible with dynamic or condenser microphones. An integrated

P48 phantom power source can be enabled if desired. Stereo

monaural headset, or even a monaural earpiece are connected to the headphone output jack. Two “push-in/push-out” rotary controls (potentiometers or “pots”) make it easy to set the level of the talent cue signals level being sent to the 2-channel headphone output. The STcontroller software application is used to configure the wide range of Model 381 operating parameters. This allows the unit’s performance to be optimized to meet the needs of specific applications.

in which they are assigned to the headphone output channels can be configured. In addition, the operation of the two rotary controls can be selected. These unique choices allow almost any required headphone monitoring situation to be implemented. Whether for use in on-air sports, in an eSports broadcast, or as a production support tool, the Model 381 should be able to achieve the desired configuration. The integrated sidetone function can be configured to operate from among three choices.
