About the Anti-Feedback Function
When automatic measurement is
not completed
• If you press the AUTO button to start the calibration
without a microphone connected or with the volume
level turned down too low, SA-1000 outputs an error
sound from the speaker and stops analysis. If this occurs,
check your connections and settings.
• If the surrounding noise level is too loud or the
microphone position is too far, SA-1000 outputs an error
sound from the speaker and stops analysis. If this occurs,
the ANALYSIS indicator light goes off.
• If you press the ON/OFF button while the ANALYSIS
indicator is lit, the indicator light goes off, and the anti-
feedback function is switched off. The results of the
correction process are stored in memory, though, so
turning the function on again returns the function to its
previous status. However, turning off the power clears
the results of the correction.
• SA-1000 does not respond to panel operations while in
ANALYSIS calibration. It responds after the calibration
is completed.
• Anti-feedback does not work for AUDIO and
KEYBOARD input.
• The sound quality is altered somewhat while the anti-
feedback is operational.
• With some settings, feedback may not be suppressed,
even after you have run the anti-feedback process with
the AUTO button.
