AKG H600 Shock Mount with Height Adjustment for DAM Goosenecks

AKG H600 Shock Mount: Twenty Decibels, Set Height and a Locking Clutch

The AKG H600 is a low-profile shock mount for permanent installation of E and ES version gooseneck modules from the Discreet Acoustics Modular series, specified by AKG for the maximum attenuation of structure-borne noise in the series at 20 dB. It requires a 2.1 in (53 mm) mounting hole, uses a low-profile plastic shell around a flexible inner rubber boot, includes a locking clutch that prevents easy removal of the gooseneck module, and ships with the A608 insert, which grips the narrow section of the gooseneck and allows custom height adjustments. Item number 2426X00030 identifies it. Against the H500 in the same family it trades a slightly larger hole for eight more decibels of isolation, a security feature and a way of setting height. Those three additions are what make it the specification for public and civic rooms.

Twenty Decibels and a Shell That Stays Out of Sight

Attenuation of 20 dB is the headline figure, and understanding what it represents explains why a designer would cut a larger hole to get it. Structure-borne noise is vibration that reaches a microphone through the object it is mounted to rather than through the air, so a gooseneck in a lectern hears knuckles on the reading surface, papers dragged across it, pens set down and footsteps travelling up a hollow plinth, and 20 dB of attenuation reduces the pressure arriving at the capsule roughly tenfold; that is the difference between a bang the audience notices and a movement nobody registers. Achieving it without a bulky housing is the second part of the design, since the shell is low profile and sits close to the surface, so a finished lectern or a veneered conference table shows a small collar rather than a piece of equipment. Broadcast and studio desks, where the shot matters as much as the sound, ask for exactly that combination.

Height Setting Through the A608 Insert

Height is the adjustment installed goosenecks most often need and least often get, and the supplied A608 insert is how this mount provides it. AKG describes the insert as gripping the narrow section of the gooseneck and allowing custom height adjustments, which in practice means the module can be set to sit lower or higher in its boot rather than only at the depth the mount would otherwise fix it at; that becomes important when a lectern is used by speakers of very different heights, or when several positions around a conference table have to present microphones at a matched height for a tidy result on camera. Consistency across a room is the real prize, because a bench of six delegate positions with visibly different microphone heights looks unconsidered even when every channel sounds fine. AKG does not publish a numeric height adjustment range for the insert, so no figure is quoted here and the range should be confirmed against the specific gooseneck being installed.

The Locking Clutch and Rooms Nobody Supervises

Security is the third distinction, and it is often the reason a specification lands on this mount rather than the simpler one. A locking clutch prevents easy removal of the gooseneck module, which converts a microphone from something that lifts out in a second into something that stays where it was installed, and in a public-access room that is a genuine requirement rather than a nicety: a lectern in a civic building, a pulpit in an unattended house of worship, a university teaching wall, a courtroom bench or a council chamber all sit unsupervised for long stretches, and equipment that can be lifted out tends to be. Installation is a single 2.1 in (53 mm) hole, so the mechanical work is no harder than for the unlocked version. Conference tables needing set heights per seat, resonant or hollow surfaces that transmit noise readily, and any room where a missing microphone would stop proceedings are the usual homes for this part.
