QSC KC12 - Factory Reset

21
• A+B+C – Channels A+B+C are sent from the output, but not Bluetooth, POST-DSP
• B-THRU – Channel B input signal is sent through, bypassing PRESETS and DSP
• EXT SUB – Applies system delay to time-align an external subwoofer that is immediately adjacent to the KC12 (<1ms), allowing for
optimal coupling.
• Output Level – Output level can be controlled independently to gain stage your system when connecting to loudspeakers,
subwoofers, or mixers from this output.
◦ -100 to +25 dB. Unity (0 dB) is default.
NOTE: When daisy-chaining a KC12 to another KC12 via the B ASSIGN OUTPUT, turn the GAIN KNOB of the receiving
KC12 all the way to max level for correct gain staging.
SETTINGS: Additional functions of the loudspeaker
• FIRMWARE VERSION – The current firmware version and the factory default name of the
loudspeaker are listed on the top bar of the settings menu. Users are
unable to edit this field.
• SCENES – Specific settings of the loudspeaker (PRESETS, CONTOURS, SUB LEVEL DELAY,
EQ, REVERB, OUTPUT) can be saved and recalled as a “SCENE”.
◦ SCENE 1 – User can recall (only) SCENE 1 which will factory restore all Scene-
savablefeatures
◦ SCENE 2 through 5 – User can SAVE and RECALL scenes with unique user settings forcommonly-used deployments
• SUB ONLY MODE
◦ OFF (Default) – The KC12 can be operated as a full system that includes the KC12T top box.
◦ ON – The KC12 MF/HF channel is muted.
NOTE: Do NOT operate the KC12S without the KC12T attached unless “SUB ONLY MODE” is ON within the Utilities
menu. If the KC12S is operated without KC12T attached and “SUB ONLY MODE” is not ON, consistent audio output will
not be possible.
• LED – Selects which combination of front and rear LEDs illuminate.
◦ FRONT and REAR (default)
◦ FRONT ONLY
◦ REAR ONLY
• SECURITY – A 4-digit code can be entered to lock the loudspeaker settings from being adjusted, until the code is re-entered. To
enter a code, use the Selector Knob to select a number, then press the ENTER button, and rotate the Selector Knob to the desired
number (0-9). After a number has been chosen, press the ENTER button again, and repeat the process for the remaining 3 digits.
After a code has been entered and the loudspeaker is locked, the user interface will return to the Home Screen, and a message will
be displayed alerting the user that the unit is locked. When any button is pressed, the SECURITY screen will be displayed, and the
user must follow the instructions above to re-enter the code to unlock the system.
◦ FULL – The entire system is locked, and no functions (including GAIN) can be accessed
oradjusted
◦ PARTIAL – The system is locked and no functions can be accessed or adjusted, but GAIN
knobs remain functional for Channel level adjustment
• UTILITIES – System Level Functions
◦ FACTORY RESET – Restores all parameters to the factory defaults. This function is permanent
and cannot be undone.
◦ TEST TONE – A test tone from 20 Hz to 20 kHz will sweep through the system allowing the
user to hear if all of the drivers are functioning properly. If you do not hear a
tone in the subwoofer or top box, or if the sound is distorted, please contact
QSC Service for assistance.
• REGULATORY – Statements for regional regulatory compliance.
