HYPERCARDIOID DYNAMIC INSTRUMENT MICROPHONE

Tailored response for musical instrument pickup–guitar cabinets,

• snare and other percussion

Hypercardioid polar pattern reduces pickup of sounds from the

• sides and rear, improving isolation of desired sound source

• Durable performance for professional applications

• Special dual-wall floating construction reduces handling noise and assures consistent performance from mic to mic

• Hi-ENERGY

neodymium magnet for improved output and

transient response

• Multi-stage flat grille design is engineered to enable easy placement as close as possible to sound source

• Corrosion-resistant contacts from gold-plated XLRM-type connector

• Rugged, all-metal design and construction for years of trouble-free use

Output from the microphone's XLRM-type connector is low impedance (Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2 hot” – positive acoustic pressure produces positive voltage at Pin 2.

To avoid phase cancellation and poor sound, all mic cables must be wired consistently: Pin 1-to-Pin 1, etc. For a high-impedance (Hi-Z) mic input, connect a Lo-Z balanced cable to a Hi-Z matching transformer (A-T CP8201 or equal) at the equipment input.

Take care to keep foreign particles from entering the windscreen. An accumulation of iron or steel filings on the diaphragm, and/or foreign material in the windscreen's mesh surface, can degrade performance.

Note: Remove the rubber sleeve at the base of the microphone handle to use the AT8471 isolation stand clamp (not included) for

manent installation.
