AD122-96 MX

Warm-up and Calibration

The recommended warm up time is 15 minutes. The AD122-96MX feature self-calibration for
consistent long-term accuracy. A complete calibration cycle (about 5 seconds in duration) is activated
at power on. A calibration cycle may be initiated by pressing both the EXIT and GO buttons
simultaneously.
The final stage of calibration occurs when audio signals in the range of -25 dB on the AD's meters are
fed to the analog inputs. This signal can be music program that is consistent in level and varies just
above and below -25, or a tone at -25 dB.
This final calibration needs to occur:
1.) After the unit is powered "On" and the initial calibration cycle is finished.
2.) Any time the clock frequency or clock source of the AD122-96MX is changed.
3.) If the AD122-96MX has been "idle" with the power "on" but no signal has been fed to its
inputs for more than one hour.
To see the operation of the final calibration after changing the clock source, with no signal present at
the analog inputs, switch on a tone at -25 dBFS feeding the analog inputs. For a few seconds after the
tone is switched "on," the level displayed on the meters will change slightly until finally settling on
"-25 dB."

Factory Defaults

The AD122-96MX can be reset to the factory defaults by holding down the EXIT button while turning
"On" the AC power. Continue to hold down the EXIT button until the unit finishes initializing and the
main screen appears:
The factory settings will not be stored unless you go to the Default Parameters screen and store them in
the RAM Preset.
In some instances, when the AD122-96MX is not operating in a consistent manner, resetting to the
factory presets may restore stable operation. It is advisable to go through the menus and write down
your settings before resetting to the factory presets. After resetting, you can go back and change the
settings to the ones you wrote down, and store them in the RAM presets.
Please Note: Soft Saturation settings are NOT stored in the RAM presets.
