THE CONNECTOR PANEL?
O MIDI IN Connector
MIDI signals from external MIDI devices can be fed to this
terminal to remotely select effects, set the pitch shift of the
PITCH CHANGE A effect, and trigger some other effects.
0 MIDI THRU Connector
The MIDI THRU connector simply re-transmits any data re­
ceived at the MIDI IN connector, permitting convenient
“chaining” of MIDI devices.
@ BYPASS FOOT SW Jack
An optional Yamaha FC5 footswitch or equivalent connected
to this jack can be used for foot control of the BYPASS
function.
o MEM./TRG. FOOT SW Jack
An optional Yamaha FC5 footswitch or equivalent can be
used to sequentially select any group of effects from the 100
available memory locations, permitting a sequence of effects
to be set up to match the flow of a live performance. When
the TRIGGER button is pressed and its LED indicator is lit,
the footswitch can be used to trigger three of the SPXSOD’s
effects; ADR-Noise Gate, Reverb & Gate, and Triggered
Pan.
o R & L OUTPUT Jacks
These two rhonayral 1/4" phone jacks deliver the stereo out­
put signal from the SPX50D to subsequent amplification or
mixing equipment. These jacks can be connected directly to
the inputs of guitar amplifiers, keyboard amplifiers, recording
equipment or mixing consoles. Since many of the SPX50D
effects are true stereo effects, we recommend connecting
both output jacks to the corresponding inputs of a stereo or
two-channel sound system in order to get the best possible
sound. If this is not possible, connect either of the OUTPUT
jacks (L or R) to the amplification equipment used.
@ INSERT IN and OUT Jacks
The INSERT IN and OUT jacks allow connection of a second
signal processor to the SPX50D which can be activated or
bypassed by using the INSERT button.
e INPUT Jack
The rear-panel INPUT jack duplicates the function of the
front-panel INPUT jack. Either — but not both — can be
used to receive the signal from your instrument or other
audio signal source. The front-panel INPUT jack takes prior­
ity, so if sources are plugged into both the front- and rear-
panel INPUTS, only the front-panel INPUT will be active.
