11.0EX-6
When troubleshooting an
EPS-16
PLUS with an OEX--6 that is not operating properly, you will
need
to
determine whether the EPS-16 PLUS
or
the OEX--6 is at fault. Ifpossible. try the
OEX--6 with another
EPS-16
PLUS.
or
try
the problem
EPS-16
PLUS
with
a different
OEX-6.
The operation
of
the OEX--6 can be tested using the following procedure:
a.
Load and select the sound called 6-0UT TEST.
b.
While playing the same note
on
the keyboard. listen to each
OEX-6
output individually.
You
should hear a single square-wave tone
in
each output and the tone in each successive output
should
be a semitone higher in pitch than the previous output.
Note that the
OEX--6 outputs
are
not designed to drive headphones directly and should
be
plugged into a suitable line-level pre-amp such
as
a mixing board.
*
If
the
EPS-16
PLUS
itself
is
defective,
the
problem
is
in
the
Main
Board.
