3. Connections: Basic System Setup
0
Input IMPEDANCE Switch
This switch determines the input impedance of the
INPUT R and L/MONO jacks, and the front-panei INPUT
jack. When directly connecting a guitar or other high-
impedance instrument to the FX900, set this switch to
the "1M" position. The "1 Ok" setting is appropriate for
standard audio equipment and other line-level sources.
0 Input Level -20dB/+4dB Switch
This switch aiiows the input sensitivity of the FX900 to
matched to the type of source equipment used. When
connecting the FX900 to professional equipment that
has +4 dB outputs, set the input ievel switch to the
"+4dB" position. The "-20dB" setting is the best choice
for most home-use audio equipment.
0 INPUT R & L/MONO Jacks
The INPUT R and L/MONO jacks allow either stereo or
mono signals to be fed to the FX900. Stereo signals
should be fed to both jacks, while a mono signal should
be fed to the L/MONO jack only. Inserting a plug into the
L/MONO jack only causes the FX900 to function as a 1 -
in/2-out type signal processor. The L/MONO jack
duplicates the function of the front-panel INPUT jack
described in the following section. If plugs are inserted
into both the front and rear-panel inputs, the front-panel
input jack takes priority.
0 OUTPUT R and OUTPUT L Jacks
These are the main stereo outputs from the FX900. We
recommend using both outputs and connecting them to
the corresponding right and left channels of a stereo
sound system, since the full impact of many of the
FX900 effects can only be appreciated in stereo. If,
however, only a mono sound system is available, use
either the OUTPUT R or OUTPUT L jack.
0 Output Level -20dB/+4dB Switch
This switch is used to match the output level of the
FX900 to the input sensitivity of the amplifier, mixing
console or other device it is feeding. For compatibility
with standard line-level inputs the ”-20dB" setting
should be appropriate, while the "+4dB” setting should
be used when the FX900 is connected to professional
equipment that has +4dB inputs.

MIDI IN Connector
The MIDI IN connector accepts MIDI signals from an
external MIDI device such as a MIDI foot controller,
keyboard, etc. The FX900 will accept MIDI PROGRAM
CHANGE messages to directly select effect programs,
or MIDI CONTROL CHANGE messages via which
individual effect parameters may be remotely controlled.
fSee page 43 for further details!
0
MIDI THRU/OUT Switch
Selects either MIDI THRU or MIDI OUT operation for the
MIDI THRU/OUT connector, described below.
0
MIDI THRU/OUT Connector
When the MIDI THRU/OUT switch is set to "THRU,"
MIDI signals received at the MIDI IN connector are re­
transmitted via this connector in real time, allowing other
MIDI devices to be "chained" to the FX900.
When the MIDI THRU/OUT switch is set to "OUT," MIDI
data corresponding to operation of the FX900 is
transmitted via this connector.

0
REMOTE Connector
This connector accepts the optional FC900 remote foot
controller unit, allowing convenient foot control of effect
group switching, program selection, bypass switching,
and other functions.
® FOOT VOL 1 and 2 Jacks
Optional Yamaha FC7 Foot Controllers connected to the
FOOT VOL 1 and 2 jacks can be used to control
specified effect parameters in real time.
[See page 45 for further details]
dJ) MEMORY INC/DEC Jack
An optional Yamaha FC4 or FC5 Footswitch may be
connected here for convenient foot-controlled selection
of effect programs. The range of effect programs that
can be selected is determined by the UTILITY mode
Footswitch Memory Recall Range Edit function (page
48).
rSee page 48 for further detailsl
dD BYPASS Jack
An optional Yamaha FC4 or FC5 Footswitch connected
here performs exactly the same function as the front-
panel [BYPASS] key. Press the footswitch once to
activate the bypass mode, and again to turn bypass off.
