  • Files saved using later Editor or console versions cannot be loaded into earlier versions.
  • Please note that some types of USB flash memories cannot be used for firmware updates, or cannot be accessed from the LS9 at all.

How to update the firmware

  • Before performing any firmware upgrade it is good practice to back-up console data to a USB memory device.
    1. Copy the following file to root directory of your USB memory.
    LS9Px_xx.PGM (x_xx shows the version number.)
    2. Insert your USB memory and power on.
    3. LS9 detects the file and shows the following message.
    "Start Loading? CANCEL[DEC]/OK[INC]"
    4. Then press [INC] key to start updating the firmware.
    5. Wait until completing the update. LS9 automatically restarts and becomes ready to use.
    6. Initialize LS9.

Performance Limits and Specifications

  • If the LS9 Editor does not return online, reset the Input Port/Output Port in the LS9 Editor "System Setup" dialog box, then select the ports again to return online.
  • Severe fragmentation of USB memory may stop the recording/playback function of the USB memory recorder.
  • The LS9 cannot recognize the files whose name start with a two-byte character.
  • Sorting titles too quickly using up and down arrow buttons on the TITLE LIST screen of the USB memory recorder will sometimes result in a malfunction and moving of another title.
  • While playing back an audio file using the USB memory recorder, the last part (maximum 400 ms) may not be played back.
  • The USB memory recorder cannot play back WMA Professional audio files.
  • The title list of USB memory is updated whenever USB memory is inserted or a file is added to or deleted from the SONGS folder in the YPE folder. Please note that update may take some time for a number of files.
  • If USB memory is disconnected while recording with the USB memory recorder, it will not play back properly since the file process is incomplete.
  • A bitmap file created by the user can be displayed on the CONSOLE LOCK screen with some restrictions, including that the file be uncompressed, 8/16/24/32 bit color, and 300KB or less.

Main Revisions and Enhancements


  • Improved the performance in which the LS9's panel operation was infrequently slow when the LS9 was connected with the LS9 StageMix.

Fixed Bug

  • Increased the stability of remote control of an external head amplifier. Through this, the following conditions have been eliminated or minimized than under the LS9 firmware V1.30:
    - Appearance of the "No Response from External HA" message.
    - Termination of communication.
  • Fixed a problem within the Flex15GEQ, when paste or recall was performed to the Flex15GEQ and to which a different band from the copied data or recall data was set, the setup was not reflected correctly.
  • Fixed a problem in which you could not reset the gain to 0 dB in rare cases for the selected band by simultaneously pressing the EQ [Q] encoder and the EQ [GAIN] encoder.
