Audio-Technica ATM650 Dépliant
• 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.
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
mater ial 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.
