User's Manual

The new I2 Instrument Microphone has been engineered from the ground up
for natural on- and off-axis frequency response, low noise, and precise polar
patterns with deep nulls. Its tiny size makes it perfect for distance miking that is
invisible in front of audiences on camera.
Complete Control: Flexible close
miking techniques are aided by
Countryman’s line of instrument
mounts, which position securely and
gently to strings, brass, and more.
Effortless Possibilities: Small size
and sonic precision makes it ideal
for X-Y, M-S, and other techniques
that rely on accurate coincident
positioning and consistent patterns.
Unparalleled Precision: The I2 maintains excellent pattern control and
frequency response at all angles, for uncolored recordings and reduced
feedback issues.
