Yamaha SPX50D - Manual (Page 6)

® UTILITY Button
This button accesses a list of utility functions allowing editing
of effect titles, MIDI control programming and increment
footswitch recall range programming.
Direct Recall Buttons (REV/DLY Group, MOD & OTHERS,
DIST Group)
These buttons provide fast direct access to the SPXSOD’s
three major effect groups.
® TRIGGER Button
When the TRIGGER button is pressed and its LED indicator
is lit, a footswitch plugged into the rear-panel MEM./TRG.
FOOT SW jack can be used to trigger three of the SPXSOD’s
effects: ADR-Noise Gate, Reverb & Gate, and Triggered
Pan. Press the TRIGGER button a second time to restore
the foot switch’s normal memory selection function.
® BYPASS Button
The BYPASS button switches the selected effect ON or
OFF, leaving the direct signal only when BYPASS is active.
® TUNER OUT Jack
The TUNER OUT jack can be connected directly to an elec­
tronic guitar tuner allowing convenient tuning without the
need to unplug your instrument from the SPX50D input and
connect it to the tuner.
® INPUT Jack
Your instrument or other audio-signal source can be con­
nected here or to the duplicate INPUT jack provided on the
rear panel. The front-panel INPUT jack takes priority, so if
sources are plugged into both the front- and rear-panel IN­
PUTS, only the front-panel INPUT will be active. The INPUT
accepts a mono 1/4” phone plug, and is unbalanced.
