Tieline MHB Input Extender – ViA Microphone Input Expander

Product Overview

The Tieline MHB input extender is a microphone input expansion unit designed specifically for the Tieline ViA portable IP audio codec, providing additional balanced mic inputs and monitoring to support more presenters and guests on location. It connects to the ViA using the dedicated rear-panel expansion port, so extra microphones appear within the ViA’s routing matrix just like the built-in inputs. This lets engineers build larger round-table, panel or sports commentary setups around a single ViA, without adding a separate mixer or codec. The compact MHB enclosure is designed for field use, with robust connectors and straightforward front-panel controls that keep setup time to a minimum during fast-paced remotes.

Key Features

• • Microphone input extender purpose-designed for the Tieline ViA portable IP codec.

• • Adds extra balanced microphone inputs to the ViA, appearing as additional channels in the ViA’s internal audio matrix.

• • Balanced mic preamps with broadcast-grade headroom and low-noise performance for use with dynamic or condenser microphones (phantom power supplied from the ViA where supported).

• • Front-panel gain controls and status indication for quick level setting in the field.

• • Additional headphone or monitor output options to provide individual monitoring for extra contributors during remotes.

• • Single-cable connection to the ViA codec using the dedicated expansion interface; powered from the ViA or from an external supply depending on configuration.

• • Rugged, compact metal housing optimised for outside broadcast and portable operation.

Applications

Use the Tieline MHB input extender whenever you need more microphone positions than the three built-in mic/line inputs on the ViA, such as sports commentary booths, panel discussions, OB vans or complex talk shows on location. By expanding the available inputs on a single codec, it simplifies cabling and control, reduces the amount of hardware you need to transport and lets you keep all routing, mix-minus and recording functions inside the familiar ViA interface.
