Handling of compact discs
CA UTI ON
1 - Introduction
The GA-30CD has been designed for the playback
of CD-DA (standard audio) format discs. In addition
to ordinary 3-inch and 3-inch CDs, it can also play
properly recorded CD-R and CD-RW discs.
Always place CDs in the tray with their labeled sides
•
facing upward.
To remove a disc from its case, press down on the
•
center of the disc holder, then lift the disc out, holding it carefully by the edges.
Avoid getting fingerprints on the signal side (the
•
non-label side). Grime and dust may cause skipping,
so keep discs clean and store them in their cases
when not being played. To clean the signal side of a
disc, wipe gently with a soft dry cloth from the center towards the outside edge.
Keep discs away from direct sunlight, and places of
•
high heat and humidity. If left in such places, warping could result.
Do not affix any labels or stickers to the label side of
•
the disc. Do not write on the disc with ballpoint pens.
Do not use cracked discs.
•
Only use circular compact discs. Avoid using non-
•
circular promotional discs, etc.
The GA-30CD cannot play CD-R/RW discs that are
•
not finalized.
Several record companies have released music discs
•
that use Copy Control and other copy-protection
systems in an effort to prevent piracy. Since some
of these discs do not comply with the CD specifications, the GA-30CD may not be able to play them.
After opening the CD player cover, if the CD is still
•
spinning, wait until it has stopped before removing it.
Do not use any record spray, anti-static solutions,
•
benzene, paint thinner or other chemical agents to
clean CDs as they could damage the delicate playing
surface. This may cause CDs to become unplayable.
Discs should be returned to their cases after use to
•
avoid serious scratches that could cause the laser
pickup to “skip.”
Beware of condensation
If the unit (or a compact disc) is moved from a cold to a
warm place, or used after a sudden temperature change,
there is a danger of condensation; vapor in the air could
condense on the internal mechanism, making correct
Precautions for placement and use
Do not place the unit in the following types of places.
Placement in such locations may cause malfunction or
reduce sound quality.
Unstable places or places with frequent vibrations
•
Near windows or in direct sunlight
•
Near heating devices or other extremely hot places
•
Extremely cold places
•
Damp or poorly ventilated places
•
Placing this amplifier near another power amplifier or
another device with a large transformer can cause hum.
Using commercially available CD stabilizers or printable
recordable discs with this player will damage the
mechanism and cause it to malfunction.
Never use a disc that has had a stabilizer mounted to it.
The residual adhesive may cause the disc to stick to the
turntable of the GA-30CD. If it sticks to the turntable,
you will need a technician to get it out.
operation impossible. To prevent this, or if this occurs,
let the player sit for one or two hours at the new room
temperature before using
Adjust the distance and angle between the devices if
this occurs.
Operation of the GA-30CD near a television or radio
may cause color distortion on the television screen
or noise in the radio signal. If this occurs, move the
GA-30CD farther away.
Use of mobile phones and other wireless devices near
the GA-30CD may cause the amp to produce noise
during use or when calls are made or received. If this
occurs, turn off the device or move it away from the
GA-30CD.

guitar signal.
3BOOST switch
Turns the internal distortion circuit ON and OFF.
OFF: The input guitar sound is heard clearly
without distortion. The GAIN knob changes
the input signal volume.
ON: The activated distortion circuit produces a
more powerful guitar sound. When ON, the

the two side speakers (3-inch). In addition to the CD
Trainer output, the effects output can also be sent to
the side speakers.
The SIDE VOLUME level is set to play CDs that have
low overall volume at a sufficient volume level. For this
reason, some CDs that have a loud overall volume may
sound distorted when played back through the amp's
speakers or attached headphones at a high level. If this
happens, please adjust the SIDE VOLUME to stop the CD
sound from distorting.
Adjust high frequencies.
