Arrakis MARC-OB Output Module Board

What This Arrakis MARC-OB Output Module Board Actually Is This is the Output Module Board for the MARC-15 console, the core module that comes standard with every MARC-15 mainframe and handles the console's fundamental output routing regardless of how you configure the rest of your board with mic, line, phone, or Bluetooth modules. Since the MARC-15 is built around a fully modular design where every function lives on its own independent module, the Output Module Board is what actually generates and manages the console's three stereo Program output mixes along with the Monitor, Headphone, and Cue systems that every MARC-15 depends on. Unlike input modules, which vary based on how many mic or line channels a particular station needs, this output module is a fixed, standard component included with every MARC-15 mainframe regardless of channel configuration. How This Module Handles the Console's Core Output Routing The Output Module Board manages the MARC-15's three separate stereo Program output mixes, each including mono mixdowns, giving your station the ability to run on-air programming, background production work, and a third independent mix simultaneously without any of them interfering with one another. Alongside these three Program buses, this module also handles the Monitor, Headphone, and Cue systems that operators depend on throughout a normal broadcast day. Because this module sits at the center of the console's output architecture, it's what actually ties together whatever combination of input modules you've chosen, routing all of that incoming audio out through the correct buses regardless of your specific mic, line, phone, or USB module configuration. Why This Module Standard on Every MARC-15 Mainframe Every MARC-15 mainframe ships with this Output Module Board included as a standard component, since the console's output routing, metering, timer, and built-in cue-talkback functionality all depend on it regardless of how many or which type of input modules you've selected. This is different from the console's input modules, where you choose your own combination of mic, line, phone, USB, Bluetooth, and studio monitor modules based on your specific studio needs, since the output side of the console handles a consistent set of core functions that every MARC-15 configuration relies on in the same way. Whether you're running an 8-module, 12-module, or fully populated 15-module mainframe, this output module works identically across all three configurations. How the Headphone and Monitor Systems Function Through This Module The headphone output managed by this module includes both a stereo, balanced, line-level output suitable for driving an external amplifier, along with a dedicated headphone amp output specifically built for driving low-impedance headphones directly. This dual output approach gives studios flexibility in how they handle headphone monitoring, whether that's feeding a larger studio monitoring system or driving headphones directly at the operator position without needing additional outboard amplification. The module's monitor system works alongside this same output architecture, giving operators a genuine, reliable way to check their mix without disrupting the actual on-air feed. Why Reed Relay Isolation Matters for This Module's Logic Functions This module includes a control room muting logic output specifically designed for triggering an on-air light, and that output is reed relay isolated to eliminate the potential for ground loops, a common source of noise and interference issues in broadcast wiring. Rather than sending this logic signal directly, the reed relay is meant to trigger another relay that actually powers the on-air light itself, keeping the console's internal circuitry properly isolated from whatever external light fixture and wiring your studio uses. This kind of careful electrical isolation reflects the broader engineering philosophy behind the MARC-15, where reliability and clean signal handling take priority throughout every part of the console's design. Who Should Be Concerned With This Output Module Since the Output Module Board ships standard with every MARC-15 mainframe, most buyers won't need to purchase this separately when buying a new console. This module becomes relevant specifically for existing MARC-15 owners who need a replacement output module due to damage or wear, since the console's modular design means this component can be serviced or swapped independently rather than requiring the entire mainframe to be sent in for repair. For any MARC-15 owner troubleshooting output, metering, or headphone monitoring issues, this module is exactly the component responsible for that functionality across the whole console.
