I2 INSTRUMENT

MICROPHONE

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.

12 Instrument Microphone Competitor Microphone

Unparalleled Precision: The I2 maintains excellent pattern control and frequency response at all angles, for uncolored recordings and reduced feedback issues.

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.

I2 Instrument Microphone: Frequently Asked Questions

Which pattern should I choose?

To get the best performance, know the angles where your microphone is most sensitive to sound, and which angles offer the best rejection of unwanted sounds.

• The omnidirectional pattern picks up all sounds from all directions equally. It has the flattest frequency response, the lowest noise level, and is the least susceptible to wind noise and vibration. The omnidirectional microphone is often used for recording and sound reinforcement of acoustic instruments such as percussion, guitar, saxophone, and piano.
• The cardioid pattern is most effective at picking up sound directly in front of the microphone, and is least sensitive to sound directly behind the microphone. Overall the cardioid picks up about 1/3 less ambient noise than the omnidirectional, so the working distance (the distance a performer could be positioned from the microphone) is approximately 1.7 times that of the omni. The cardioid is an excellent choice when you can position the microphone directly toward the sound you wish to record (a lead singer, for example) and directly away from unwanted sound sources (a crowd or loud monitor).
• The hypercardioid pattern has a narrower pick up pattern in front than the cardioid, overall better rejection of ambient noise, and the working distance is about twice that of the omni. The hypercardioid has a small "pick-up lobe" directly behind the microphone. This means that the maximum rejection areas are behind and to the sides (about 60 degrees away from the rear of the microphone on either side). The hypercardioid is the best choice when the loudest unwanted sounds—like speakers—can be positioned in these nulls.

How can I mic a piano?

FOR MONO. USE OMNIDIRECTIONAL WITH CARM SHOE OUT FOR STEMO. USE CARDIOIDS BACK TO BACK SPACED 1/4+

For mono: use double-sided foam tape to attach an I2 Omni facing the lid of the grand piano near the center board, or positioned over the strings on a mic stand. For stereo: place two I2 Cardioid mics on edge 1/8" apart facing left and right. The lid should always be open 3" to 6" (Closing the lid creates a "boxy" sound.)

If the lid must be closed or removed, place an I2 Omni on one of the support braces near the middle of the instrument, as shown. Experiment with placement to avoid resonances. For stereo try one on the long support near the middle and one near the upper treble section.

For upright pianos try affixing an l2 Omni to one of the central backposts, as shown. Experiment with placement as not all parts of the soundboard resonate the same. Two mikes in different areas should yield even better results.

How can I mic a saxophone?

The I2 Brass Instrument Mount has vibration-damping jaws that tightly grip the bell, with an adjustable wire that can be positioned at the center of the bell or placed to capture sound through the keys.

How can I mic a violin / viola?

The I2 Violin Mount positions the microphone between the bridge and tailpiece in a secure, vibration isolating mount. Point the microphone toward the violin body.

How can I mic a cello / double bass?

The positioning arm on the I2 Cello Mount allows for a variety of microphone positions, including under the bridge or over the F-hole. Make sure the silver (active) side is pointed toward the body.
