Switch controls on/off distribution of DC power to connected modules. Compatible connectors facilitate simple connections to associated 5100-Series modules.


Model 5110 Mic/Line Input ModuleThe Model 5110 Mic/Line Input Module is a compact, self-contained 2-channel module intended for use in custom broadcast, live-performance, and general audio applications. Offering a "building block" of resources, the Model 5110 provides two channels of high-performance audio capability in an easy-to-use yet technically sophisticated package. The module's basic functions include selectable input gain, 48 V phantom power, status LED indicators, and analog and digital audio outputs. Module operation requires only an externally-provided source of 12 Vdc. Advanced features include user control "lock out," metadata insertion, and remote monitoring/control capability. Applications for the Model 5110 include sports broadcasting booth packages, remote news gathering "fly-packs," stadium audio/video interface (I/O) locations, and government/corporate/performance space infrastructure projects. Versions are available for compatibility with SMPTE® and EBU analog and digital audio reference levels.

Model 5121 Mic/Line Input ModuleThe Model 5121 Line/IFB Output Module is a compact, self-contained 2-channel module intended for use in custom broadcast, live-performance, and other specialized audio applications. The module provides broadcast and production talent cueing interfaces, specifically two line-level ("dry") and one IFB ("wet") outputs, in an easy-to-use yet technically sophisticated package. The module's basic functions include selectable analog and digital audio inputs, input level and status LED indicators, two analog line-level outputs, and a 2-channel DC-biased ("wet") broadcast-standard IFB output. Remote monitoring capability is included to support advanced applications. Module operation requires only a source of analog or digital audio, along with an externally-provided source of 12 Vdc. Applications for the Model 5121 include sports broadcasting booth packages, remote news gathering "fly-packs," stadium audio/video interface (I/O) locations, and other broadcast-infrastructure projects. Versions are available for compatibility with SMPTE® and EBU analog and digital audio reference levels.

Model 5132 Party-Line Interface ModuleThe Model 5132 Party-Line Interface Module is a compact, self-contained unit for use in custom broadcast, live-performance, and general party-line intercom applications. The module provides a high-quality 2-channel party-line to analog line-level ("4-wire") audio signal interface in an easy to use yet technically sophisticated package. The module's basic functions include two channels of 2-wire-to-4-wire conversion with auto-null capability, input and output level metering, a +28 Vdc party-line power source with two channels of 200 ohm intercom audio termination, and DC output control and status monitoring. With the internal party-line power source enabled, beltpack user devices can be directly connected. Alternately, the Model 5132 can be connected into an existing party-line system that includes a power source and intercom audio terminations. Two sets of 4-wire analog inputs and outputs interface the Model 5132 with a variety of external audio transport, intercom, and infrastructure equipment. Module operation requires only an externally-provided source of 12 Vdc. Advanced features include remote control and monitoring capability. Applications for the Model 5132 include sports broadcasting booth packages, remote news gathering "fly packs," stadium audio/video interface (I/O) locations, and government/corporate/performance space/aerospace test infrastructure projects. Versions are available for compatibility with SMPTE® and EBU analog and digital audio reference levels.

Model 5140 Intercom Interface ModuleThe Model 5140 Intercom Interface Module provides a unified connection interface for both party-line (PL) and 4-wire (line-level) intercom systems, offering a reliable and easy-to-use "I/O" panel for remote broadcast and infrastructure applications. The Model 5140 was specifically designed to allow "guest" users, including media crews, production or uplink trucks, and temporary equipment, to be quickly and efficiently linked to ports on a host intercom system. By providing both party-line and 4-wire connections a fixed or mobile facility can offer user's maximum flexibility in their system interconnect. This can reduce the effort required to "link" systems, help to ensure excellent audio quality, and minimize the involvement of senior engineers and technicians. Versions are available for compatibility with SMPTE® and EBU analog and digital audio reference levels.

Model 5150 Video Generator ModuleThe Model 5150 Video Generator Module is a compact video generation module designed to enhance production and delivery options for the education, corporate, worship, and broadcast markets. Supports a video input and a video output by way of standard BNC connectors. Optional optical transceiver module provides an optical output in addition to the electrical output. Can be used stand-alone or connected directly with other 5100-Series modules for video transport, audio input, audio output, IFB, and intercom applications.

Model 5152 Video Generator/Audio Embedder ModuleThe Model 5152 Video Generator/Audio Embedder Module is a compact module includes all the features of the Model 5150 with the addition of allowing four stereo digital audio signals to be embedded into the SDI signal. The eight channels of audio will always be embedded, whether or not an external SDI source is present. The four digital audio inputs are compatible with the digital audio output provided by the Model 5110 Dual Mic/Line Input Module. Up to four Model 5110 modules can be directly connected. Can be used stand-alone or connected directly with other 5100-Series modules for video transport, audio input, audio output, IFB, and intercom applications.

Model 5154 Video Generator/Audio De-Embedder ModuleThe Model 5154 Video Generator/Audio De-Embedder Module is a compact module that includes video generation as well as de-embedding of audio arriving from the incoming electrical or optional optical SDI signal. Audio outputs are in the form of four 75 ohm, unbalanced stereo digital audio signals for a total of eight channels. Can be used stand-alone or connected directly with other 5100-Series modules for video transport, audio input, audio output, IFB, and intercom applications.

Model 5180 Ethernet Switch ModuleThe Model 5180 Ethernet Switch Module is a combination 5-port copper (UTC) Ethernet switch and single-mode optical fiber Ethernet media converter.
