2.2 Usage
2.2.1 Control Button
The control button has different meanings in different situations, also depending on
whether it is pressed briefly or pressed and held for longer period. All the operation
functions are logical and intuitive:
Short press when the speaker is on will toggle the AntiMode correction ON
–
(status led GREEN) and OFF (status led ORANGE).
Long press when the speaker is on and microphone connected will begin the
–
AntiMode automatic room calibration process. (more info on chapter 2.4)
Long press when the speaker is on but without the microphone connected will
–
begin Active Suspension (ASCM) calibration (more info on chapter 2.5)
Short press in the middle of the calibration process (AntiMode or ASCM) will
–
abort the calibration and return the settings of the previous calibration.
Short press when the speaker is in STANDBY (led is RED) will turn on the
–
speaker.
2.2.2 Status LED
Status LED signals the user about different situations and statuses
Green LED indicates that the speaker is on and Antimode is engaged
–
Orange LED indicates that the speaker is on and AntiMode bypassed
–
Blinking orange LED indicates that the speaker is performing calibration
–
Red LED indicates that the speaker is in "Stand By" state or in the middle of
–
calibration
Blinking red LED is warning about input level nearing A/D saturation threshold or
–
some error condition (See errors and warnings)
2.2.3 Input Gain Control
The input gain control adjusts the input sensitivity of the input A/D converter.
Attention: always keep the input gain setting in minimum while performing AntiMode
calibration to avoid any disturbances originating from the audio source or cables. If
the A/D converter is almost saturating due high input voltage, the status led will start
blinking red light. If the the input voltage becomes too high, some amount of
distortion can occur. To prevent this, the input gain control can be adjusted to a lower
value.
