AKG HM1000 Modular Hanging Microphone Module 32.8 ft Cable XLR Output

AKG HM1000: Modular Hanging Module With Cable and Powering Built In

The AKG HM1000 is a hanging microphone module from the Discreet Acoustics Modular series, supplied with a permanently attached 32.8 ft (10 m) twist-resistant cable and an integrated inline phantom power adapter that terminates in a 3-pin balanced XLR male connector. It does not include a capsule, and that is the fact to settle before ordering: the module is the flown mount, the cable and the powering stage, while the polar pattern is chosen separately by threading on one of the compatible capsule heads. Because the powering adapter is already part of the assembly, no additional module is needed to reach a phantom-powered console, install mixer or automixer input. For an integrator that means a ceiling can be cabled and hung before anyone decides how wide the pickup needs to be.

Choosing the Capsule After the Ceiling Work Is Finished

Five capsule patterns fit the threaded system connector at the business end of this module: the CK31 cardioid, the CK32 omnidirectional, the CK33 hypercardioid, the CK47 shotgun and the CK80 supercardioid. Polar pattern determines how much of a room a flown microphone hears, and separating that decision from the mounting work is genuinely useful in a live building, where the reverberation and loudspeaker layout a designer predicted on paper is not always the room a commissioning technician finds. Contacts at the capsule joint are gold-plated and self-cleaning, and the connection is a metal thread rather than a press fit, because the whole point of specifying this class of hardware is that nobody wants to go back up to a truss to chase an intermittent microphone. Swapping a hypercardioid head for a cardioid on a lift in twenty minutes is a far better outcome than re-hanging a fixed microphone.

HM1000 Versus the Modular Plus HM1000 M

Two versions of this hanging module exist and they are not interchangeable, so the suffix has to be read carefully. This one, without the M, belongs to the earlier Discreet Acoustics Modular generation: it takes the CK31 family of capsules and brings its 10 m cable out through an integrated inline phantom power adapter to a standard 3-pin male XLR, needing nothing else. The Modular Plus version, designated HM1000 M, instead accepts the newer CK41, CK43 and CK49 capsules and terminates its cable on a Modular Plus system connector, which means a separate Modular Plus powering module is mandatory before it can reach an XLR input. Integrators servicing an older sanctuary or chamber should confirm which generation the capsules on the shelf belong to, because ordering across the divide produces two parts that physically will not work together.

Integrated Cable, Aiming Clamp and the Slow-Drift Problem

Cable is integral rather than an accessory, and its 32.8 ft (10 m) of specially treated lead is engineered against a specific long-term failure. Ordinary microphone cable keeps a memory of the spool it came from, and as a room warms and cools across a season that memory unwinds, rotating a flown microphone off the aim an installer set on ladder day; the treatment here resists that twisting, and owners credit it with keeping ceiling microphones on target for years. A spring steel hanging clamp completes the mechanical picture by gripping the cable and holding the capsule at a chosen vertical angle, which is what allows three or four modules across a wide choir riser to be aimed identically for consistent level from side to side. Buyers do note that 10 m is adequate for most ceilings and occasionally short for high truss work, so the run to the nearest wall plate is worth measuring before the lift is booked.

Powering, Filtering and Visual Status Indication

Phantom power from 9 to 52 V feeds the assembly at a low 2 mA draw, delivered through the inline adapter that also applies a 250 Hz low-cut filter and presents the 2,000 ohm-friendly balanced output. Low current consumption is more than a footnote on an install job, because a phantom supply in a compact install mixer or an automixer frame is shared across every input, and a ceiling array of four or six hanging modules on a modest supply is exactly where an inefficient microphone starts to misbehave. A switchable LED ring gives visual confirmation during commissioning, the supplied light-ring expander enlarges that indicator for long sight lines in a large chamber, and the ring can be defeated entirely for a blacked-out ceiling or a camera-facing position. Most technicians use the indication during soundcheck and switch it off before the room opens.

Ceiling Arrays, Retrofits and Who Specifies This Module

Applications concentrate wherever a microphone must be flown rather than stood: choir and ensemble pickup from ceiling or truss positions, theatre stage-area coverage, audience and ambience capture for broadcast and live stream, and ceiling microphone arrays across conference and board rooms. All-metal construction with a non-reflective treatment suits ceilings that appear on camera, which is why courtroom and hearing-room installers use it for record-keeping pickup and why lecture-capture rooms adopt it for room microphones that must not clutter a table. Retrofits are the other strong case, since an existing capsule from the earlier modular series can be re-hung on a new module without touching the capsule inventory. Between the integrated cable, the built-in powering and the free choice of pattern, it is the flown mount that lets an installer plan the ceiling first and the acoustics second.
