rts and their function

NETWORK connector

This connector allows the LS9 to be connected to a Win-
dows computer via a CAT3 (transfer rate: maximum 10
Mbps) or CAT5 (transfer rate: maximum 100 Mbps) com-
patible Ethernet cable. This is used mainly for controlling
mix parameters or editing scene memories and libraries
from the dedicated “LS9 Editor” application program.

WORD CLOCK IN/OUT connectors

These are BNC connectors used to transmit and receive
word clock signals to and from an external device. The
WORD CLOCK IN connector is internally terminated by
a 75 ohm resistor.

2TR OUT DIGITAL jack

This is a coaxial jack that outputs the digital audio signal
of a specified channel in consumer format (IEC-60958).
This is used mainly to output STEREO/MONO channel
signals.

2TR IN DIGITAL jack

This is a coaxial jack that inputs a stereo digital audio sig-
nal in consumer format (IEC-60958). The signal input
from this jack can be patched to any input channel.

MIDI IN/OUT connectors

These connectors are used to transmit and receive MIDI
messages to and from external MIDI devices. The MIDI
IN connector receives messages from an external device,
and the MIDI OUT connector transmits messages from
the LS9. These are used mainly for recording LS9 param-
eter operations or scene/library changes on an external
device, or for remotely operating LS9 parameters.

LAMP connector (LS9-32 only)

This is an XLR-4-31 connector that supplies power to a
separately sold gooseneck lamp (e.g., Yamaha LA5000).
The brightness of the lamp can be adjusted in the screen.

AC IN connector

Connect the included power cable to this connector to sup-
ply power to the unit.

POWER switch

This switch turns the power on/off.

Grounding screw

To ensure safe operation, be sure to ground the LS9
securely. The included power cable has a three-conductor
plug, so if the AC outlet is grounded the LS9 will be
grounded appropriately. If the AC outlet is not grounded,
establish a secure ground connection from this screw. Cor-
rectly grounding the unit is an effective way to eliminate
hum and interference noise.

Cooling fan vent

This is the vent for the cooling fan inside the console.
When placing the console, be careful not to block this
vent.
