| 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.
The ATM250 includes an AT8471 isolation clamp to provide
secure mounting, versatile positioning and effective dampening of
unwanted mechanical noise.
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.
Features:
- Frequency response tailored for kick drum, percussion, brass,
and
- other highly dynamic instruments

feedback
- Corrosion-resistant contacts from gold-plated XLRM-type
- connector
- Rugged, all-metal design and construction for years of
trouble-free
- use
- Includes isolation clamp for shock protection, secure
mounting and
- easy positioning
