RODE Microphones NT4 - Manual (Page 8)

• The NT4 is an easy to use, precision stereo
condenser microphone. Choirs, orchestras, drum
over-heads, solo or ensemble instruments, and
many other situations may all be recorded with
the ambience and ‘space’ that only a true stereo
microphone like the NT4 can capture.
• The two capsules used in the NT4 measure 1/2” in
diameter and have a cardioid polar pattern. The
cardioid patterns pick-up sound from in front of
the microphone and reject sound from the rear.
This helps with reducing unwanted sound such as
reverberation and audience sound from the rear of
the capsules.
• It is crucial when stereo recording to have the
capsules closely matched, as in the NT4. The
polar frequency response of each capsule must
be matched because much of the sound in an XY
stereo arrangement is picked up off-axis by each
capsule. The tone can be varied by rotating the
NT4 on its axis, so that the capsules are pointing
towards different areas of the sound source. It is
recommended that you experiment with subtle
position changes to help you achieve your desired
results. The matched capsules of the NT4 allow
for an accurate response when recording a wide
variety of sources in various locations.
• To ensure the lowest noise/distortion, your mixer
input gain control should be set so that the Peak
Program Indicator (PPI) LED fl ashes ON during
peaks (high levels) of the program source (Voice/
Instrument). If there is no PPI, adjust the input
gain while listening for distortion of the sound. As
distortion is heard, reduce the gain gradually until
the sound is undistorted (clean).
