Room Correction
The Room Correction adjustment, which is part of the Automatic
Calibration procedure, uses four microphones to measure the acoustic
characteristics and modal properties of the listening room and then
applies specific parametric filters to the outputs. The main advantages of
the Room Correction adjustment are:
• it addresses what is important for the audio – the objective is not to
make the numbers better, but to make the audio sound better.
• resonances are a feature of the room – treating them helps the entire
room, and improves the bass uniformity of the room.
• the amount of correction can be adjusted by the listener.
• the calibration is simple and reliable – it can even screen out external
noise sources.
For more information about the Room Correction adjustment and why
it’s an important part of enabling the system to run at optimal
performance levels, refer to the “Understanding Room Correction”
section in the Appendix.
Room Correction is not available with manual calibration.
Automatic
Calibration
Follow the steps below to perform the Automatic Calibration procedure.
The calibration is done in two steps: Check Microphones and Run
Calibration. Until the Check Microphones test is performed successfully,
the Run Calibration menu option is grayed out and not available. This
prevents calibration errors due to potential microphone problems and
verifies that the Nº502 can accurately detect all of the microphones before
beginning the calibration.
Note The HSG microphone kit is required for the Automatic Calibration procedure.
Do not use other microphone brands.
Be sure to read and observe the care and handling instructions included
with the microphone kit to ensure optimal microphone performance.
Caution!
The microphones and cables included in the HSG microphone kit are
delicate and require careful handling. Dropping or otherwise physically
abusing the microphones may cause errors during use or irreparable
damage to the microphones. Treat the microphone cables carefully; do
