An overview of the LS9 ■ Effects and graphic EQ that can be patched into a desired signal path There are eight virtual racks, in which you can mount effects or graphic EQ and then patch them into the desired signal route. Graphic EQ can be mounted in racks 1-4, and effects or graphic EQ can be mounted in racks 5-8. You can simultaneously use up to four high-quality multieffects, which include reverb, delay, multi-band compressor, and various modulation-type effects. These can be used via an internal bus, or inserted into a desired channel. For the graphic EQ you can select either 31-band graphic EQ or Flex 15 GEQ. These can be inserted into the desired channel or output. The Flex 15 GEQ allows you to adjust the gain for any fifteen of the thirty-one bands. Since two Flex 15 GEQ units can be mounted in a single virtual rack, a total of up to sixteen graphic EQ units can be used simultaneously. ■ A recorder function that's useful for sound checks or recording mixes A recorder function is provided, allowing you to use USB memory to record the output of the STEREO bus or a MIX bus, or assign an audio file in USB memory to a desired input channel or monitor output and play it back. Supported file formats are MP3 (MPEG-1 Audio Layer-3) for recording, and MP3, WMA (Windows Media Audio), and MPEG-4 AAC (Advanced Audio Coding) for playback. However, DRM (Digital Rights Management) is not supported. This function is convenient when you want to record the mix output of a specific bus, or if you want to play back a song from the speakers during the sound check. ■ Cascade connections in the digital domain A second LS9 console or a digital mixer such as the Yamaha M7CL or PM5D connected via a digital I/O card installed in a slot can be cascade-connected in the digital domain. Of the MIX buses, MATRIX buses, STEREO (L/R) bus, MONO buses, and CUE (L/R) bus, the desired buses can be merged, and all mixed bus signals can be cascaded individually. ■ Security functions that can be specified at user-level or system-level User levels can be distinguished into three levels (administrator, guest, user), and the functionality available to each non-administrator user can be restricted. Passwords can be specified for the administrator and users, preventing important settings from being changed accidentally. Information specific to each user (user level, system settings, and user-defined key settings) can be stored on USB memory as a "user authentication key." By loading your own user authentication key from USB memory, you can instantly set up the ideal operating environment for yourself. ■ I/O card expansion The rear panel provides one slot (LS9-16) or two slots (LS9-32) in which separately sold mini-YGDAI cards can be installed. AD cards, DA cards, or digital I/O cards can be installed in these slots to add inputs and outputs port. 10 LS9-16/32 Owner's Manual
