AKG MF M Flush Mount Flange Module for DAM+ Microphones with Blind Cap

AKG MF M: A DAM+ Microphone Position Built Into the Table

The AKG MF M is a flush-mount flange module for DAM+ Series microphones that recesses a complete microphone position into the tabletop rather than mounting it on the surface. Its slim body integrates a DAM+ Series powering module, so the electronics that give a DAM+ gooseneck its output live underneath the table and out of view, and the gooseneck itself can be detached and removed whenever the position is not in use. A blind cap is supplied to seal the connector outlet, leaving a flush interface in the table and protecting the contacts against dust. The AKG item number is 3165H00220. It is the mounting choice for rooms where the furniture matters as much as the audio.

Why Structure-Borne Noise Is the Problem It Solves

Reducing body noise transmitted from tables is the function AKG names first for this module, and it is the reason a flush flange beats a surface bracket acoustically. Structure-borne noise is vibration that travels through solid material rather than through air, so a pen tapped on a boardroom table, a laptop set down or an elbow shifting on the surface arrives at the capsule as a thump with no acoustic path to attenuate it. Isolating the microphone where it meets the table intercepts that energy before it reaches the capsule, which is why the flange is specified alongside the switchable bass roll-off available on the DAM+ powering modules rather than instead of it. Council chambers and courtrooms feel this most, because those are the rooms where papers, gavels and water glasses share a surface with an open microphone all day.

The Powering Module Goes Inside the Flange

Every DAM+ gooseneck ending in M has no output of its own and requires a separate powering module, and the MF M is designed so that module fits inside the flange body instead of dangling below the table on a cable. That arrangement matters at commissioning time because the powering module is where the phantom feed, the bass roll-off setting and, on the programmable version, the switch and indicator behaviour all live, so putting it in a fixed, protected, repeatable location means every seat in a room is configured identically. Integrators specifying a 40-seat chamber can therefore prepare the flanges on the bench, set every module the same way, and install a known-good assembly at each position. That repeatability is what turns a large conference fit-out from a bespoke job into a production line.

The Blind Cap and the Room With Nothing on the Table

A special blind cap ships with the module and seals the connector outlet whenever the microphone has been lifted out, leaving an attractive flush interface in the table and sealing the connector against dust. Rooms that serve more than one purpose need exactly this, because a chamber used for a formal hearing on Tuesday and a community meeting on Wednesday cannot leave 40 goosenecks standing to attention through both. Facilities managers get a table that wipes clean with nothing protruding, while the AV department keeps a fixed, wired, phantom-fed position ready to accept a microphone in seconds. Broadcast panel desks, executive boardrooms and multipurpose lecture tables all end up specified this way for the same reason.
