Audio-Technica ATM650 HyperCardioid Dynamic Instrument Microphone

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.

When using the ATM650 in settings with a stage monitor speaker, the speaker should be located 135° off axis (45° off the rear of the microphone). This placement, in conjunction with the microphone's uniform hypercardioid pickup pattern, will virtually eliminate the possibility of undesired audio feedback.

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 more secure, permanent installation.

Features:

• Tailored for extended-range, high-fidelity vocal reproduction
• 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 articulate vocal reproduction
• Multi-stage grille design offers excellent protection against plosives and sibilance without compromising high-frequency clarity
• Corrosion-resistant contacts from gold-plated XLRM-type connector
• Rugged, all-metal design and construction for years of trouble-free use
