C1.2 User Manual

5.1.7 FACTORY SETTINGS
Serial number: Displays the serial number of your C1.2. This serial number is also written on a sticker at the
back of your C1.2.
Firmware version: Indicates the version of the firmware that the C1.2 is currently running. Periodically
check CH Precision’s website to see if a newer version is available. It could add new features or correct
bugs. Note that the CH Control App indicates that a device is not up to date by displaying its name in
orange instead of red.
Update firmware: Selecting Update launches the C1.2 firmware update process. A USB flash disc drive with a
valid set of firmware must be inserted in the A-shaped USB port. Please refer to the corresponding section of
this manual for more detail on firmware update procedure.
Factory reset: Resets all parameters to their default factory values. This can be useful if you made some
changes that you don’t know how to revert.
Installed options: Lists the hardware configuration of your C1.2.
Remote control code: Selects to which set of RC5 commands the C1.2 will respond to. Pre1 is the standard RC5
Preamplifier set, Pre2 is an alternate RC5 Preamplifier set (it corresponds to the set of commands the C1.2
remote control sends by default). When ‘None’ is selected, the C1.2 cannot be controlled by a remote control
anymore.
Device mode: Preamplifier (volume control on) or Converter (volume control off)
Calibrate: Launch automated calibration left and right channel DAC stage. It takes about 40s per channel to
complete. For optimal performances, please make sure the C1.2 is warmed-up (i.e. turned on for more than an
hour) before running calibration.
