An overview of the LS9
LS9-16/32 Owner’s Manual
■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 multi-
effects, which include reverb, delay, multi-band compres-
sor, 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 play-
back. 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 (admin-
istrator, guest, user), and the functionality available to
each non-administrator user can be restricted. Passwords
can be specified for the administrator and users, prevent-
ing important settings from being changed accidentally.
Information specific to each user (user level, system set-
tings, 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 your-
self.
■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.
