Studio Technologies Model 381 On-Air Beltpack

Just imagine a broadcast tool that seamlessly integrates cutting-edge audio technology with user-friendly operation meet the Model 381 On-Air Beltpack. This compact yet powerful device is engineered to support complete broadcast "stand-up" on-air positions, leveraging Dante audio-over-Ethernet technology to deliver superior audio performance. With main and talkback output channels, talent cue (IFB) input, and sidetone capabilities, the Model 381 is a versatile solution for broadcasters.

The Model 381 is fully compatible with Dante Domain Manager (DDM) software and adheres to the AES67 standard, ensuring smooth integration into modern networked audio environments. Designed for broadcast sports, live entertainment, eSports, news-gathering, and streaming applications, this beltpack offers professional audio quality and an intuitive user experience. A single Power-over-Ethernet (PoE) connection, along with a dynamic or phantom-powered microphone and headphones or earpiece, is all you need to get started.

Configuration is a breeze with the STcontroller software, allowing you to adjust microphone preamplifier gain, P48 phantom power, headphone signal routing, sidetone operation, and talkback button action. The Model 381 boasts exceptional audio quality, characterized by low distortion, minimal noise, and high headroom, thanks to its meticulous circuit design and robust components.

The Model 381 serves as an "all-Dante" solution for on-air talent, offering two Dante audio input channels for talent cue signals and two output channels for main and talkback functions. The integrated sidetone feature provides a microphone confidence signal when needed. The top-panel pushbutton switch combines talkback and "cough" functions, with five configuration options to tailor its operation to your needs.

Setup is straightforward: connect via an etherCON RJ45 jack to a PoE-enabled network switch, providing both power and digital audio. The 3-pin XLR microphone input accommodates both dynamic and condenser microphones, with optional P48 phantom power. Stereo headphones or a monaural earpiece connect easily to the headphone output jack, with rotary controls for adjusting talent cue signal levels.

The Model 381's durable aluminum alloy enclosure is lightweight and rugged, featuring a stainless steel belt clip for easy attachment. Its curved top surface minimizes interference with clothing and visibility on camera. The device connects to a LAN via a 100 Mb/s twisted-pair Ethernet interface, using a Neutrik etherCON RJ45 connector for secure connections in demanding environments.

Utilizing Dante audio-over-Ethernet technology, the Model 381 supports two Dante transmitter and two receiver audio channels, assignable via the Dante Controller software. It supports sampling rates of 44.1, 48, 88.2, or 96 kHz with a bit depth of up to 24, ensuring high-quality digital audio transmission. The unit is also compatible with the AES67 interoperability standard and Dante Domain Manager software.

The Model 381's audio performance is top-notch, featuring a low-noise, wide dynamic-range microphone preamplifier and a VCA dynamics controller to preserve audio quality. Configuration options allow selection of the audio source for the Dante main output channel, either pre- or post-compressor. The digital audio is processed through a 32-bit microprocessor, ensuring precise control and flexibility.

With the STcontroller software, users can configure the Model 381 to suit specific applications and preferences, without the need for mechanical switches or button sequences. Options include microphone preamplifier gain, P48 phantom power, headphone output performance, sidetone operation, and talkback button function. The sidetone feature offers three configuration choices, and the talkback button can be customized with five options.

Future-proof your setup with the Model 381's capability for firmware updates via a USB connector, ensuring ongoing enhancements and compatibility. The device utilizes Audinate's Ultimo integrated circuit for the Dante interface, with firmware updates available through the Ethernet connection.

In summary, the Model 381 On-Air Beltpack is a sophisticated, reliable, and flexible solution for professional broadcasters, offering unparalleled audio quality and ease of use in a compact form factor.
