ORTF Stereo Skill:
When recording with ORTF microphone, keep the microphone
•
at least 1 meter away from the ensemble.
Adjust the microphone position so that the room space could
•
be heard, while excellent direct sound is maintained.
Keep the most of the ensembles/orchestra within 90° coverage.
•
Keep the microphone high enough that each instruments/artists
•
has an un-block direct path to the microphone.
Set the PAN control to extreme Left and Right. Do not pan the
•
signal in between L and R.
Choose a high quality recorder, or mixer.
•
Adjust the nominal recording level at about -18dBfs for clas-
•
sical music without compressor/limiter, while keep the peak at
about -3dBfs to -6dBfs.
Always use a shock mount.

What is “ORTF”?
ORTF is brief from “Office de Radiodiffusion
Télévision Française”. This standard was estab-
lished for stereo broadcasting that brings optimal
stereo performance to most audio systems. 2
cardioid capsules arranged with 110°
open angle and 17 cm space away.
The benefits of ORTF brings more spa-
cious sound than coincident XY tech-
nique, yet avoid “hole in the center” problem of
spaced AB technique which exhibits very good
spacious sound.
ORTF technique balanced excellent stereo po-
sitioning, and spacious sound that please most
of the audience than AB or XY/MS stereo tech-
nique. ORTF is a technique that can be easily
handled by beginners or video production crews
with a fix ORTF stereo microphone such as
S502. Experienced engineer can also takes this
advantage with S502, or use a pair of S241 with
stereo bracket for ORTF recording.
Maintainence
Condenser microphone shall be kept in low hu-
midity environment for best sound performance.
S
tore the condenser microphones in air-condi-
t
io
ned room or dehumidifier to keep away form
moi
sture. Clean air is another important factor.
Keep
away from smoking environment to avoid
tar re
siduals.
