Yamaha FX500B - Manual (Page 6)

3. Connections: Basic System Setup
O
DC12V IN Jack and Cable Clip
The DC output cable from the supplied AC Adaptor
should be connected here. When connecting the power
supply, make sure that the FX500B POWER switch Is
in the OFF position (extended), then plug the AC
adaptor output cable into the DC 12V IN jack, and
finally the adaptor's AC plug into a convenient AC wall
outlet. The cable clip located immediately below the DC
12V IN jack helps to prevent accidental unplugging of
the power supply during use. Wrap the DC cable firmly
around the clip a few centimeters from the plug end.
CAUTION!
Do not attempt to use a different AC adaptor to power
the FX500B. The use of an incompatible adaptor may
cause irreparable damage to the FX500B, and might
pose a serious shock hazard I
I INPUT Jack
This jack duplicates the function of the front-panel
INPUT jack described in the following section. It is
important to note, however, that only one of the INPUT
jacks can be used at a time. If plugs are inserted into
both the front and rear-panel inputs, the front-panel
input jack takes prbrity.
I OUTPUT LEVEL Selector
This switch is used to match the output level of the
FX500B to the Input sensitivity of the amplifier, mixing
console or other device it is feeding. For compatibility
with standard line-level Inputs the -10 dB setting
should be appropriate, while the -20 dB setting should
be used when the FX500B is connected to a high-
sensitivity input — the input of a bass amplifier, for
example.
o OUTPUT R and OUTPUT L Jacks
These are the main stereo outputs from the FX500B.
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 FX500B effects can only be appreciated in stereo.
K, however, only a mono sound system is available,
use either the OUTPUT R or OUTPUT L jack.
o PHONES LEVEL Control and PHONES Jack
For private listening or practice when an external
sound system cannot be used, a pair of standard
stereo headphones (with a 1/4" stereo phone plug or
appropriate adaptor plug) can be plugged into the
PHONES jack. The PHONES LEVEL control adjusts
the headphone listening level.
O MIDI IN Connector
The MIDI IN connector accepts MIDI signals from an
external MIDI device such as a MIDI foot controller,
keyboard, etc. The FX500B 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._______

O MEMORY INC/DEC, TRIGGER (TAP TEMPO DELAY)
Jack
An optional Yamaha FC4 or FC5 Footswitch may be
connected here for convenient foot-controlled selection
of effect programs or "tap tempo delay" control in which
the footswitch is used to set delay time for the delay
effects. The funetbn of the footswitch is determined by
the UTILITY mode Foot Switch Function Select
funetbn (page 22). The range of effect programs that
can be selected when the footswitch is assigned to
memory selectbn is determined by the UTILITY mode
Footswitch Memory Recall Range Edit funetbn (page
23).
o 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.
