Countryman Associates Isomax 2 All-Purpose

Unlike other choir mics, Countryman's unique Isomax II-H hypercardiod mic is designed to pick up the whole choir evenly. That means the front row of singers doesn't overpower the back rows, and nobody sounds like a soloist simply because he or she is closest to the mic.

With our comprehensive guide to hanging the mics, you can eliminate unwanted noise from the audience, musicians, and monitor speakers. Best of all, the Isomax II-H's coverage pattern reduces the number of mics necessary to capture the whole choir.

You can fly these tiny, lightweight microphones almost invisibly from a thin wire spanning across the choir, rather than suspending bulky equipment from high ceilings. That makes our choir mics infinitely easier to replace, position and control - without the risk of equipment accidentally falling and injuring people below.

Supplied with windscreen, cable spool, stiffener for hanging and phantom-powered preamp.

Applications:

• Virtually invisible mics for choir, stage and audience

Performance:

• Unusually uniform pickup over entire choir or production
• Text book perfect cardioid and hypercardioid polar patterns for excellent stereo separation and rejection of unwanted sounds
• Precision directional patterns are uniform with frequency
• Excellent gain before feedback
• Handles high SPL

Style:

• Sleek, small, lightweight mic doesn't distract performers or house li> Easy to hang without scaffolding

Durability:

• Special 50' cable won't twist with temperature changes.

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, and 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.

Frequency Response:
ISOMAX 2 O: 20 Hz to 20 kHz
ISOMAX 2 C, H: 50 Hz to 20 kHz

Overload Sound Level: 150 dB SPL @ 1% THD

Output Impedance: 600 Ohms +/- 2% balanced, transformerless. Will drive load impedance without distortion at full rated SPL.

Maximum Noise Level:
ISOMAX 2 O: 25 dB SPL A-weighted
ISOMAX 2 C, H: 29 dB SPL A-weighted

Power: Phantom, 6 to 50 Volts @ 4 mA. Voltages below 24V will result in reduced overload SPL.

Dimensions: 5/16” (8 mm) x 5/8” (16 mm) x 5/32” (4 mm) excluding cable strain bushing.

Sensitivity: -57 dB (0 dB = 1 V/Pascal. Open circuit)
