If an I/O card (expected to go on sale in the future) that supports the external head amp (Yamaha
AD8HR) remote protocol is installed in an LS9 slot, you’ll be able to remotely control parameters
such as the external head amp’s phantom power (+48V) on/off, gain, and HPF from the LS9.
For an example of actual connections, refer to the owner’s manual of the I/O card.
Here’s how to control the external head amp (subse-
quently called “external HA”) from the LS9 via an I/O
card installed in a slot.
1
Connect the LS9 and external HA.
Refer to the owner’s manual for the I/O card and for
the external head amp.
2
Repeatedly press the [RACK 5-8] key to
access the EXTERNAL HA screen.
The EXTERNAL HA screen includes the following
items.
1 COMM PORT box
This box lets you select the communication port for
the currently-installed I/O card(s).
You can choose from the following communication
ports.
● SLOT {SLOT1}
Select the communication port for the I/O card
installed in the slot {slot 1}.
● SLOT2 (LS9-32 only)
Select the communication port for the I/O card
installed in slot 2.
B ID / Model name / +48V master
This displays information for the external HA
mounted in the rack. The ID number is assigned auto-
matically as 1 to 2 {1 to 4} in the order in which
devices are connected to the I/O card. This area also
shows the on/off status of the master phantom power.
C Virtual racks
These are two {four} racks in which remotely control-
lable external HA units can be mounted. If an external
HA is mounted, its settings (gain setting, phantom
power on/off, HPF on/off) are shown. When you move
the cursor to a rack and press the [ENTER] key, the
EXTERNAL HA popup window for that rack will
appear.
D EXTERNAL HA PORT SELECT popup but-
ton
This button accesses the EXTERNAL HA PORT
SELECT popup window, where you can specify the
input ports to which the external HA mounted in the
rack will be connected.

To select the communication port for the I/O
card, move the cursor to the COMM PORT
box, use the dial or the [DEC]/[INC] keys to
select a port, and press the [ENTER] key.
4
To specify the input ports for an external
HA, move the cursor to the EXTERNAL HA
PORT SELECT popup button for that rack,
and press the [ENTER] key.
