Level and Distance Autocalibrate
First, prepare the calibration microphone supplied with the C 2, by unscrewing its barrel to open
the battery compartment, inserting the AA battery supplied with its + (button) end toward the
switch, screwing the barrel back on, and pushing the microphone’s On-Off switch toward the dot.
Plug the microphone into the “Cal Mic” input on the front of the C 2. Then sit in your favorite
listening chair, holding the microphone with its mesh screen pointing upward. Tilt the Master
remote’s thumbpad to scroll down to the autocalibration mode you want (level or distance),
press the center of the thumbpad to start the calibration, and sit back.
At the start of
distance autocalibration
, the C 2 checks the ambient noise level again, then
plays repeated brief bursts of low-level test noise signals through each speaker in turn. Distance
autocalibration requires about two minutes, and during this time the on-screen display shows
which speaker is being measured, how near completion its measurement is, and the required
delay, in ms (milliseconds) that the C 2 will apply.
Note: Autocalibration is a precision measuring and adjusting technique that
requires a reasonably quiet environment. Do not move the microphone once
calibration starts. And do not talk or make noise during autocalibration, especially
level autocalibration, as high ambient noise or fluctuating noise levels may
interfere with and interrupt the process.
If autocalibration is interrupted by extraneous noise, the OSD will ask for silence,
count down for five seconds, and then resume from where it left off. It will keep try-
ing to autocalibrate until it either succeeds or it gives up and displays “Exit to Abort.”
To exit Autocal, press the ESC (escape) button on the Master remote, not the Exit
button on the front panel.
If the subwoofer cannot be autocalibrated after three tries, the OSD will request
that you adjust subwoofer level manually, as discussed under “Level setup,”
above. If the subwoofer’s level is still too high or low, adjust the gain of the inter-
nal or external amplifier powering it.
