Q & A
How can the internal GEQs be set up to work on the console's outputs?
Press the [RACK 1-4] and [RACK 5-8] keys simultaneously to open the Virtual Rack, and set up
the required input and output routing from there. These settings can also be made from the individual
RACK displays: refer to page 159 of the Owner's Manual.
How can the internal GEQs be connected into the system?
Specify the IN and OUT points to insert a GEQ unit into the desired point in the signal path. Prefer
to page 161 of the Owner's Manual.
What is Flex15GEQ?
Flex15GEQ is a stereo 1-band graphic equalizer that allows you to use up to 15 bands at a time.
Can I copy the settings from channel A of a Flex15EQ equalizer from the library to a 1-band GEQ?
The equalizer library settings are saved with the equalizer type, so it is not possible to copy the
settings from one type of equalizer to another. Refer to page 174 of the Owner's Manual.
How is Rev-X different from other reverb effects?
The Rev-X reverb effect is smoother and has superior high-frequency characteristics. This new
algorithm was originally an option that was sold separately, but it is now included in the LS9 consoles.
How can I apply the internal reverb to the monitor outputs?
Press the [RACK 1-4] and [RACK 5-8] keys simultaneously to open the Virtual Rack, and set up
the required input and output routing from there. These settings can also be made from the individual
RACK displays: refer to page 159 of the Owner's Manual.
RACK 6 and 8 seem to have fewer internal effects than RACK 5 and 7.
RACK 5 and 7 additionally have Freeze (a simple sampler) and HQ.Pitch effects.
What's the difference between EQ Type 1 and Type ?
When boosting two adjacent frequency bands the Type  equalizer produces less interference
between bands. But when cutting adjacent bands the Type 1 equalizer has a deeper effect.
Can MY cards be used to expand I/O capacity?
A variety of Mini-YGDAI cards offering I/O expansion in a range of audio formats can be
used. The MY4-DA card can be used, for example, to add four more analog MIX outputs with XLR
connectors. An MY8-ADDA card could be used to add 8 analog inputs and 8 analog outputs via
Euroblock connectors. For digital I/O the MY16-AE could be used to provide 16 inputs and outputs in
AES/EBU format. Refer to page 187 of the Owner's Manual for details on supported cards.
Can 96 kHz cards such as the MY16-AE96 be used?
Yes. The card can be used, but the LS9 and card sampling rate will be either 44.1 kHz or 48 kHz.
Can outboard devices be inserted into the signal path?
An optional I/O card can be used for outboard inserts. Refer to page 101 of the Owner's Manual
for details.
Can the inputs and outputs of the MY8-ADDA96 card be used as inserts?
Yes. Select the slot in which the MY8-ADDA is installed from INSERT the channel HOME display.
Are there any MY cards with built-in head amplifiers?
There are no MY cards with built-in head amplifiers, but you can combine an MY16-AE card with
the AD8HR remote head amplifier or the MY8-ADDA96 card with the MLA8 to provide additional
head amplifiers for microphone input.
Does the AD8HR allow remote control?
Not currently. I/O cards with HA remote protocol communication capability are planned for the
future. Check our home page for release details.
Can litlight lamps be used? What are the lamp specifications?
-volt 5-watt lamps can be used.
How can the Ether connector be used with the Studio Manager?
To connect via the Ether connector, the DME-N Network Driver must be installed in addition to the
Studio manager, and the LS9 must be registered in the DME-N Network Driver.
I can't connect to the Studio Manager.
Since the connection is made via the Ethernet connector, the proper settings must be made to
allow communication. Refer to page 16 of the Owner's Manual for details.
I've checked and re-checked my connections, and I keep getting a "Wrong Port Setting" error.
The computer is connected properly.
Connect the LS9 to the computer using a CAT-5 cross cable. Some computers are capable of
automatically rectifying this problem.
When I LINK with the Studio Manager, I'm asked for a password.
The user status is "Administrator" and a password has been specified. Check with the system
administrator for the password, or change the user status to "Guest." Refer to page 187 of the Owner'
s Manual for details.

What's the difference between the MIX and MATRIX buses?
MIX buses have VARI and FIXED types. The VARI type allows the send level to be varied for AUX
type operation, while the send level of the FIXED type is fixed at nominal for BUS type operation. The
MATRIX buses are used to further group the MIX bus signals. MATRIX buses have variable send level
and no other types. Refer to pages 1 and 14 of the Owner's Manual for details.
How are the MIX buses used? Are there no AUX or GROUP outputs?
The MIX buses have VARI and FIXED types. Use VARI type is ideal for AUX send applications,
while the FIXED type is suitable for group sends. Refer to pages 1 and 14 of the Owner's Manual for
details.
The number of MIX outputs and OMNI OUTs are different.
The OMNI outputs are the physical output connectors on the rear panel. The stereo outputs,
16 MIX bus outputs, 8 MATRIX bus outputs, and monitor outputs are all internal signals that can
be assigned to the OMNI OUT connectors. Only the signals that will actually be used need to be
assigned to the OMNI OUT connectors. If you need more physical outputs, you can expand the
console's output capacity by installing Mini-YGDAI cards in the expansion slot(s). Refer to page 97 of
the Owner's Manual for details.
What's the difference between the MIX bus VARI and FIXED types, and how are they switched?
MIX buses have VARI and FIXED types. The VARI type allows the send level to be varied, while
the send level of the FIXED type is fixed at nominal. The type can be switched via the MIX parameters
in the SETUP display. Refer to page 1 of the Owner's Manual for details.
What's the difference between the OMNI OUTs and AUX or BUS outputs?
The OMNI outputs are the physical output connectors on the rear panel. The MIX bus output
signals (AUX and GROUP) can be assigned to these connectors as required. Refer to page 97 of the
Owner's Manual for details.
There is no ST OUT connector. Where's the stereo output?
Output signals are assigned to the rear-panel OMNI OUT connectors for physical connection
to external devices. With the initial default setup the stereo outputs are assigned to OMNI OUT
connectors 7 and 8 on the LS9-16, and to OMNI OUT connectors 15 and 16 on the LS9-. Refer to
page 95 of the Owner's Manual for details.
What can you do via the RECORD display?
The RECORD display makes it easy to record to a USB memory, or play back audio files saved on
a USB memory. Refer to page 105 of the Owner's Manual for details.
What kind of files are used by the USB Memory Recorder?
Files recorded on the LS9 are recorded in MP format. In addition to MP files, WMA and AAC
files can be played back. Refer to page 105 of the Owner's Manual for details.
I copied some MP files from my computer to a USB memory that I then connected to the LS9, but
I can't see the files.
Audio files will only be recognized by the LS9 if they are placed in the SONG folder inside the YPE
folder on the USB memory. Refer to page 108 of the Owner's Manual for details.
How long can I record or play to or from a USB memory using the USB Memory Recorder?
10 minutes of 18 kbps audio data corresponds to about 10 megabytes of memory, so with a 18
MB USB memory you can record or play back for up to approximately  hours.
Can I monitor the recorder's playback output while recording?
You cannot record to and playback from a USB memory at the same time. Refer to page 105 of
the Owner's Manual for details.
Can I connect an external hard disk to the USB connector?
Only operation of USB memory devices with a capacity of  gigabytes or less is guaranteed.
External hard disks cannot be used.
What is the quality level of the head amplifiers?
The head amplifiers are inherited from Yamaha's top-line PM consoles, and have been specially
tuned for exceptionally musical response. The HA gain setting can be stored with scene data.
When adjusting the head amp gain the sound cuts out at some points.
The internal gain control is designed to switch over every 6 dB, causing a brief interruption output.
What's the difference between the Flex15GEQ and the 1Band GEQ?
The 1Band GEQ modules are single-channel 1-band graphic equalizer on which you can boost
and/or cut all 1 bands. The Flex15GEQ units are stereo graphic equalizers with 1 bands, 15 of
which can be boosted or cut simultaneously. You can also use the faders to directly control boost or
cut in individual bands. Refer to pages 161 and 16 of the Owner's Manual for details.
Does the LS9 support multi-speaker surround?
The LS9 has an LCR mode (using L, R and Center buses), but you also use the MIX or MATRIX
buses to control other multi-speaker setups. If you need surround panning for recording or post-
production applications, however, you might need to consider one of Yamaha's digital production
