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.

Connect the LS9 and external HA.
Refer to the owner’s manual for the I/O card and for
the external head amp.

access the EXTERNAL HA screen.
The EXTERNAL HA screen includes the following
items.

This box lets you select the communication port for
the currently-installed I/O card(s).
● SLOT {SLOT1}

installed in the slot {slot 1}.

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.

lable external HA units can be mounted. If an external

EXTERNAL HA popup window for that rack will
appear.
