Optimus CONCERTMATE 690 42-4035 Portable Electronic Keyboard

PREPARATION

CONNECTING POWER

For portable use, you can power your Concertmate 690 using internal batteries. Using optional adapters, you can also power it from a standard AC outlet or your vehicle’s cigarette lighter socket.

Notes:

• Connecting an AC or DC adapter automatically disconnects internal batteries.
• Always disconnect an AC or DC adapter when you finish using the Concertmate 690.

Using Batteries

Your Concertmate 690 can use six AA batteries for power. For the best performance, we recommend alkaline batteries, such as RadioShack Cat. No. 23-552.

Cautions:

• Use only fresh batteries of the required size and recommended type.
• Do not mix old and new batteries, different types of batteries (stan- dard, alkaline, or rechargeable), or rechargeable batteries of differ- ent capacities.

1. Set MODE to POWER OFF.
2. Press the tab on the battery compartment cover in the direction of the arrow, then pull up to remove the cover.
3. Put the batteries into the compartment as indicated by the polarity symbols (+ and –) marked beside the compartment.
4. Replace the cover.

Notes:

• If you do not plan to use the Concertmate 690 with batteries for a week or more, remove the batteries.
• If the Concertmate 690 sounds weak or does not work properly, replace all six batteries. Do not mix old and new batteries.

Caution: Dispose of old batteries promptly and properly.

Cautions:

• Always remove old or weak batteries; batteries can leak chemicals that can destroy electronic parts.
• Dispose of old batteries promptly and properly.

Using AC Power

You can power your Concertmate 690 from a standard AC outlet using a 9-volt AC adapter, such as Cat. No. 273- 1656.

Cautions:

• You must use an AC adapter that supplies 9 volts of DC power and delivers at least 500 milliamperes. Its center tip must be set to negative, and its barrel plug must properly fit the Concertmate 690’s DC 9V jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the Concertmate 690 or the adapter.
• Always plug the AC adapter into the Concertmate 690 before you plug it into the AC outlet. Always unplug the AC adapter from the AC outlet before you unplug it from the Concertmate 690.

1. Set MODE to POWER OFF.
2. Insert the AC adapter’s barrel plug into the DC 9V jack on the rear of the Concertmate 690.
3. Plug the adapter into a standard AC outlet.

Using Vehicle Battery Power

You can power your Concertmate 690 from your vehicle’s cigarette lighter socket using a DC adapter, such as Cat. No. 270-1562.

Cautions:

• You must use a DC adapter that supplies 9 volts of DC power and delivers at least 500 milliamperes. Its center tip must be sent to negative, and its barrel plug must properly fit the Concertmate 690’s DC 9V jack. The recommended adapter meets these specifications. Us- ing an adapter that does not meet these specifications could damage the Concertmate 690 or the adapter.
• Always plug the DC adapter into the Concertmate 690 before you plug it into the cigarette lighter socket. Always unplug the DC adapter from the cigarette lighter socket before you unplug it from the Concertmate 690.

1. Set MODE to POWER OFF.
2. Connect the adapter’s 5.5 mm outer diameter/2.1 mm inner diameter plug to the adapter’s cord, matching TIP to negative (-).
3. Set the adapter’s voltage switch to 9 volts.
4. Insert the adapter’s barrel plug into the Concertmate 690’s DC 9V jack.
5. Plug the other end of the adapter into the vehicle’s cigarette lighter socket.

10. To stop an auto-rhythm, press START/STOP again.

Using FILL-IN

The Concertmate 690 lets you insert a variation into any of its 100 preset auto-rhythms.

While an auto-rhythm is playing, press FILL-IN. The Concertmate 690 inserts a 1- to 2-measure variation, then automatically resumes the original rhythm pattern at the end of the current measure. To insert another variation, press FILL-IN again.

To insert a variation longer than 1-2 measures, hold down FILL-IN. The Concertmate 690 plays the variation until you release FILL-IN, then automatically resumes the original rhythm pattern at the end of the current measure.

USING AUTO ACCOMPANIMENT

After you select an auto-rhythm, the Concertmate 690 lets you automatical- ly add a harmonic accompaniment.

You can select from two auto accompaniment types- easy random fingering or standard fingering. Both methods are explained in detail in the following sections. But, in brief, to add an auto accompaniment pattern, first set MODE to CONCERT CHORD for easy random fingering or to FINGERED for standard fingering. Then use the “accompaniment keys” (the 18 keys with raised labels above them) to select the chord. Use the rest of the keys to play the melody.

Easy Random Fingering

The easy random fingering method lets beginning keyboard players easily select and play a chord. The number of accompaniment keys you press determines the type of chord played. The following chart shows the type of chord that plays when you press one, two, three, or four accompaniment keys at the same time.

The lowest note you play determines the key of the chord. For example, if the lowest note is C, the Concertmate 690 plays a C chord.

Note: You can press any labeled note(s) to the right of the lowest note in the chord to produce a minor, seventh, or minor seventh chord.

Follow these steps to start easy random fingering auto accompaniment.

1. Set VOLUME to MIN.
2. Set MODE to CONCERT CHORD.
3. Select and enter an auto-rhythm.
4. To start the auto-rhythm and auto accompaniment at the same time, simply press the desired accompaniment key(s). To start the auto-rhythm before you begin the auto accompaniment, press START/STOP. Then, at the desired interval, begin the accompaniment by pressing the accompaniment key(s).
5. Adjust TEMPO △/▽ and VOLUME to the desired levels.
6. To change chords without interrupting the rhythm, simply press the auto accompaniment key(s) required to form the new chord.
7. To stop auto accompaniment and auto-rhythm, press START/STOP.
   Note: After you press the auto accompaniment key(s), the keyboard plays until you press other keys to play a different chord or until you press START/STOP.

ADJUSTING THE POLYPHONY/TEXTURE

The Concertmate 690 lets you adjust the polyphony and texture of its sound.

Note: “Polyphony” refers to the level of harmony and the number of notes played to produce the sound. “Texture” refers to the sound’s quality or depth.

Your Concertmate 690 is automatically set to high-level polyphony/texture every time you turn it on and begin play- ing.

To switch to low-level polyphony/texture at any time during play, simply press SOUND POLY/TEXTURE. To switch back to high-level polyphony/ texture, press it again.

Based on the selected feature and the polyphony/texture setting, you can play as many as eight notes at the same time, or as few as one note.

Note: It might be difficult to tell the difference between the high- and low-level polyphony/ texture settings at low (MIN) volume with certain sound selections. If this occurs, adjust the volume slightly toward MAX and try again.
