System Connectivity and Electrical Requirements
The gooseneck microphone features an integrated XLR-3-12 equivalent 3-pin male connector at the base of its φ12 mm copper alloy shaft. This balanced connector plugs directly into compatible phantom-powered XLR female receptacles on mixer-amplifiers, audio processors, lectern connection plates, or dedicated tabletop bases. Because the unit utilizes an electret condenser transducer element, active DC phantom power is mandatory for operation.
System engineers and AV technicians must verify that the upstream audio mixer, preamplifier, or digital signal processor supplies constant phantom power within the rated range of 9 V to 52 V DC across the balanced line. Connecting the unit to an unpowered dynamic-only microphone input will result in zero audio signal transmission. The 120 Ω balanced rated impedance supports long cable runs to audio distribution racks without high-frequency loss or signal degradation.
Mechanical Mounting and Base Compatibility
Mechanical integration can be achieved through surface-mount XLR sockets on speech desks, podiums, conference tables, or via an external weighted base. The microphone is designed for direct plug-in compatibility with the optional ST-800 dedicated desktop microphone stand base, which provides stable tabletop placement for conference rooms, auditoriums, and lecture halls.
- Base Mounting: Align the 3-pin XLR-3-12 equivalent connector with the mating receptacle on the ST-800 stand or desk flange, inserting firmly until the XLR locking mechanism engages securely.
- Windscreen Attachment: Slide the included dedicated windscreen accessory over the electret condenser capsule head prior to deployment to guard against breath moisture, environmental dust, and plosive air blasts.
- Weight Handling: With a net unit weight of 135 g (total catalog gross weight of 0.6 kg), the lightweight copper alloy assembly exerts minimal strain on mounting sockets and table fixtures.
Acoustic Positioning and Gooseneck Adjustment
The 420 mm overall shaft length incorporates two separate flexible adjustment points positioned along the body. These dual flex zones allow precision angle configuration, enabling the sound technician or presenter to align the cardioid capsule directly toward the speaker's mouth while maintaining a clean line of sight across lecterns and meeting tables.
The unidirectional cardioid polar pattern provides tight directional pickup across the 60 Hz to 20,000 Hz frequency response range. Proper alignment maximizes acoustic gain-before-feedback and rejects off-axis ambient noise in reverberant environments such as worship places, shopping malls, and large auditoriums. Operating temperature must be maintained within the rated limit of 0 °C to +40 °C (32 °F to 104 °F).
