The Interspace MasterCue V5 is a sophisticated, rack-mountable audio follow video (AFV) and machine control module designed for broadcast automation and master control environments. Its primary function is to provide frame-accurate, deterministic control of external devices—such as video servers, tape decks, or graphics engines—while simultaneously managing the routing and mixing of associated audio channels. The module acts as the central intelligence for creating seamless transitions between program sources, executing complex "cues" that coordinate video switching, audio crossfades, and downstream device triggers from a single timeline or command. This level of integration is critical for unattended or lightly staffed broadcast operations, enabling the execution of intricate on-air events with precision and reliability.

A core strength of the MasterCue V5 lies in its advanced audio processing and mixing capabilities. It functions as a digital audio mixer, capable of handling multiple stereo pairs, applying gain and delay adjustments, and performing clean crossfades between audio sources that are locked to the corresponding video cuts. The system manages audio embed/de-embed processes and ensures perfect lip-sync throughout the broadcast chain. It interfaces with industry-standard routers and switchers via serial protocols (like VDCP, P-Bus, or EmBER+) and GPIO connections, allowing it to orchestrate an entire playout and production ecosystem. Configuration is achieved through dedicated software, where operators can build and visualize event timelines, set audio levels, and define device control parameters.

Built for mission-critical 24/7 operation, the MasterCue V5 emphasizes stability and redundancy. It is designed to integrate into a master control switcher frame or operate as a standalone unit, often paired with redundant power supplies and control networks. The module provides comprehensive monitoring and logging, alerting engineers to any deviations from the programmed events. By consolidating video switching, audio mixing, and machine control into a single, tightly synchronized hardware platform, the MasterCue V5 eliminates the timing uncertainties inherent in using separate, software-based systems. It delivers the robust, frame-accurate performance required for flawless commercial insertion, program junctions, and complex live-to-tape production.
