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.

The ISOMAX 2 is a Countryman classic, still delivering the industry’s
tightest pattern control for an all-purpose mic. Available in omni, cardioid,
hypercardioid, and bidirectional/gure 8 versions, the ISOMAX 2 offers truly
frequency-independent patterns—unlike competing mics that become
omnidirectional at low frequencies. This precise response captures strings,
wind, brass and percussion beautifully, with exceptional gain before feedback
and excellent rejection of the rest of the band. What’s more, they’re so
affordable, you’ll find plenty of ways to use them!
Applications
• Inside or outside musical
instruments, placed on or hung
over stages and hidden in sets for
theater, motion pictures, and TV.
• Audience mics and stage oor mics.
• Available in all directional patterns
including omnidirectional, cardioid,
hypercardioid, and bidirectional/
figure 8.
Style
• Sleek, small, lightweight mic
doesn’t distract the instrumentalist
or the house
• Lightweight and easy to hang
without scaffolding, eliminating the
risk of bulky equipment falling on
performers or the house.
Performance
• Textbook-perfect polar patterns
for excellent stereo separation and
rejection of unwanted sounds.
• Very low distortion at the high
sound levels encountered
inside instruments, with super-
flat frequency response for an
uncolored, very clean sound.
• Directional pattern is frequency-
independent, so the microphone
doesn’t become omni at low
frequencies.
• Excellent gain before feedback.
• Handles very high SPL.
