Your new Ovation guitar is equipped with the latest in a series of preamps
that have provided musicians with leading-edge performance designed spe-
cifically to complement the unique character of Ovation guitars.
Please refer to the appropriate diagram on the following pages to help ac-
quaint yourself with the features and functions of your instrument.
VOLUME: Adjusts the overall output level of the preamp.
BASS: Adds or subtracts the low frequency content of the signal.
MID: Controls the amount of a broad range of frequencies in
the middle of the sound spectrum of the guitar.
MID1: Controls the amount of power in lower middle frequencies.
MID2: Controls the amount of power in upper middle frequencies
TREBLE: Adds or subtracts the high frequency content of the signal.
EQ IN/OUT: Engages or bypasses the EQ controls.
PRESHAPE: Engages or bypasses a fixed tone enhancement circuit.
MID SHIFT: Moves the center frequency of the midrange control.
NOTCH SW: Enables or disables the Notch Filter (see ).
NOTCH POT: This control is used to tune a very sharp and deep filter
designed to reduce feedback when using high-gain amplifi-
cation. At a high volume level, your guitar may “feedback”
causing a low, steady tone to come from your speakers.
With the notch filter enabled, slowly tune this control to
the feedback frequency (CW=higher frequency, CCW=lower
frequency) until the feedback is reduced.
TUNE/CAL: This switch turns on the built-in tuner for approximately 60
seconds. Press a second time while playing a note and this
pitch will become the calibration point for operation
(handy when tuning to an “out-of tune” instrument). During
the tuning operation the guitar output will be muted. If you
finish tuning prior to the 60 second timer returning the tuner
to idle (and un-mute), you may press this button again to
manually return the preamp to normal operation.
TUNER LEDs: These LEDs indicate the note being played and whether it’s
sharp or flat. Tune string up or down until the LED lights.
BAT: When steadily illuminated, indicates that the battery is low
and should be changed soon. Also intermittently flashes
when plug is inserted into jack to confirm normal operation.
RELEASE: Pressing this button will release the module from its recep-
tacle. Use this button to access to the battery compartment.
MODULE: The preamp is housed within this module and mates to the
receptacle mounted in the body. Remove this module to gain
access to the battery compartment. See the illustration on
the last page for instructions on replacing the battery.

The XLR jack on the OP-50 gives you a professional, balanced-
line connection to mixers and high-end acoustic amps. The phan-
tom power capability allows your mixer to power the preamp.
Any XLR cable with a ground-to-shell connection (Ovation P/N
9658-0) is required for the auto power-on function. A “dummy
plug” (Ovation P/N 9659-0) inserted into the 1 /4"jack can be
used instead, if the proper XLR cable is not available.
The 1 /4" jack on all models provides an unbalanced, line-level
connection to most any amplification system. Inserting a plug
into this jack also turns on the preamp system. Please note
that the tuner is functional without any connection.
