1 Pascal = 10 dynes/cm2 = 10 microbars = 94 dB SPL Specifications are subject to change without notice.

Setting Up the ATM650 Microphone

Attach the microphone to a compatible stand using the provided AT8470 stand clamp.
If needed, use the threaded adapter to fit the microphone onto different stand sizes.

Connecting the Microphone

Connect the ATM650 microphone to your audio recording device using the included Integral 3-pin XLRM-type connector.

Positioning the Microphone

Place the microphone in a hypercardioid pattern for optimal sound capture. Experiment with different angles to find the best position for your recording.

Maintaining the Microphone

Store the microphone in the soft protective pouch when not in use to prevent damage. Clean the microphone regularly with a soft cloth to remove any dust or debris.

Product Usage Instructions

Tailored response for musical instrument pickup–guitar cabinets, snare and another 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.
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.
