Yes. The number of inputs and outputs can be expanded by using cascade connections or installing mini-YGDAI cards. See the following URL regarding mini-YGDAI card support. http://www.yamahaproaudio.com/myguide/index.php
Yes. To remotely control LS9, you will need the following software:
LS9 Editor, Studio Manager, and DME-N Network Driver can be downloaded free of charge from the following URL.
http://www.yamahaproaudio.com/downloads/firm_soft/
To connect LS9 to your computer, connect a CAT3 or CAT5 Ethernet cable from the LS9's rear panel NETWORK connector (RJ-45) to the computer's LAN terminal.

No, simultaneous operation from multiple computers is not possible. Only a single LS9 can be controlled from a single computer (LS9 Editor).
By using LS9 Editor, you can control most mixer settings and parameters while viewing them on your computer screen.
One of the greatest advantages of using LS9 Editor is that you can edit the console's internal settings even while offline. This means you can setup routing, GEQ, effects, and dynamics, as well as assign names before arriving at a location,. Since the screen of your computer gives you a realtime view of the state of the mixer, you can use your computer as an external display for the LS9, or control the LS9 in realtime from your computer.
Also you can use your computer's keyboard to rapidly enter or edit channel names or scene names.
No.All functions of the LS9 are accessible from the control interface on the LS9 itself. A computer is not necessary.
There is no connector specifically for wireless networks. Connect your wireless LAN transceiver to the LS9's rear panel NETWORK connector.
Yes. You need to install a mini-YGDAI card that supports the remote protocol for control of Yamaha AD8HR units. You will be able to turn on/off the external mic preamp's phantom power (+48V) and adjust parameters such as gain and HPF remotely from the LS9. You may also store/recall these settings as scenes.

Yes. LS9 can be cascaded with other LS9 mixers or digital mixers equipped with a slot such as the Yamaha M7CL, PM5D, or 01V96. You can also cascade the LS9 with an analog mixer via an AD/DA card. There is no limit on the number of units that can be cascade-connected. The signal delay will increase depending on the number of units between the cascade master and cascade slave devices.
The following parameters are linked for cascade connected LS9s.
No, data for each device must be managed by each device
No, channels may only be moved within a single device.
No, only channels within the same device can be linked.
By installing an AVY16-ES card, you can connect and remotely control up to two AD8HR units with the LS9-16 and up to four AD8HR units with the LS9-32.
Yes, but the number of connectable units will not simply be doubled. Since LS9 does not have dedicated connectors for cascading, a slot is used for cascade connections. Thus, the answer will vary depending on the number of used buses and the type of mini-YGDAI card.
The table below show an example of when a 16 channel I/O card that divides the connectors into groups of 8 channels is used. For an MY16-AE card, the table below indicates the relationship between the number of AD8HR units, the number of cascade buses, and the total number of input channels.
| Cascade bus channels | Number of AD8HR units that can be connected | Number of analog input channels | Number of digital input channels |
|---|---|---|---|
| 8ch | 2 units | 48ch | 4ch |
| 16ch | 0 units | 32ch | 4ch |
| Cascade bus channels | Number of AD8HR units that can be connected | Number of analog input channels | Number of digital input channels |
|---|---|---|---|
| 8ch | 6 units | 112ch | 4ch |
| 16ch | 4 units | 96ch | 4ch |
| 24ch | 2 units | 80ch | 4ch |
| 32ch | 0 units | 64ch | 4ch |

Four multi-effect processors are provided. These four effects can also be used as 31-band GEQ or Flex15 GEQ.

Functionality for Add- on effects is not provided. However LS9 comes with the equivalent of Add-on effect AE031: REV-X as a standard feature.
Yes. A de-esser is provided on Dynamics 2, and can be used on any input channel.

A maximum of eight 31-band GEQ units, or
sixteen Flex15 GEQ units (eight sets) can be used.
The two types can also be used in combination.

An example of using two 31-band GEQ units and fourteen (six sets of) Flex15 GEQ units in combination
In a normal 31 band GEQ you can boost or cut as many of the 31 faders as you like.
In a Flex 15 you can only boost or cut 15 faders at one time, but you get two independent channels.
It's the same quality EQ and the same number of bands, just a limit on the number you can use at the same time.
Yes.
In the GEQ screen, turn FADER ASSIGN on, and you'll be able to use the top panel faders to control the GEQ.

Input/output for insertion can be assigned only via a mini-YGDAI card.
By installing an MY8-ADDA96 card, it is possible to connect eight channels of analog input/output.
Yes. In the input patching screen, you can assign any input to a ST IN channel.
In the default state, the outputs of virtual racks 5--8 are assigned so that they can immediately be used as effect returns.
Recall Save takes priority.
To obtain a stereo CUE signal the POST PAN button of the CUE screen must be on.
However, be aware that with the POST PAN button on, you will no longer be able to use input CUE to monitor the signal being sent to the MONO bus from an input channel that's set to LCR mode.

No, there is no VCA group function.
Instead, you can use the Channel Link function. The Channel Link function allows you to link and move faders while preserving level differences.
By moving a fader while holding down the SEL key, you can adjust individual faders without affecting other faders in the same group.

Yes, eight mute groups are provided.
A dedicated mute master key is not provided, but you can assign this function to a user-defined key and use it as a mute master key. User-defined keys 9 and 10 are already assigned as the master keys for mute groups 1 and 2.
Mute groups 1-8 can be used with both input channels and output channels. Both can exist within the mute group of the same number, and operated simultaneously.
When you turn mute on, the channels belonging to that mute group will be set to the state in which their panel (ON) key is off, and will not output a signal. The LED of the panel (ON) key will blink, indicating that it is muted.

Use the Channel Link function. With the Channel Link function, you can control the Ch On status of multiple channels by using the [ON] keys.

Yes, sine wave (variable 20 Hz-20 kHz) and pink noise (with Burst function) are provided.

No, delay is not provided for the headphone output.
It is 600 ms (approximately 206 meters).

Yes. If you've assigned one channel of a stereo-paired Mix/Matrix bus to a custom fader, both channels will move in tandem when you move the custom fader.
Multiple faders cannot be assigned to a single custom fader.
However, input channel faders that are assigned to stereo-assigned Mix/Matrix buses or LinkFader groups will move in tandem.
Yes. Holding down the SEL button overrides any channel links allowing you to do operations on individual channels . On mixers such as the 01V or DM2000, you can hold down the SEL button and operate a fader to adjust its level without affecting other channel-linked faders.
The LS9-16 has 16, and the LS9-32 has 32.
You can increase the number of mic inputs by connecting an external preamp such as AD8HR. AD8HR is an AD unit with remotely controllable mic preamps.
Up to two units can be connected to the LS9-16, providing 32 additional mic inputs.
Up to four units can be connected to the LS9-32, providing 64 additional mic inputs.
In order to connect AD8HR's, a mini-YGDAI card must be installed in the LS9's slot.
If the AVY16-ES card is installed, you'll be able to remotely control the mic preamp gain.
Yes.
For all channels, all mic preamp settings including the preamp gain and phantom power can be stored/recalled as a scene.
In addition, by installing an AVY16-ES card, you can connect up to two (on the LS9-16) or four (on the LS9-32) AD8HR units with remote mic preamps, and store/recall their gain settings as part of the scene.

Yes, phantom power is available on all channels.
