●
Avoid using your amplifier in the following locations to prevent
possible damage:
• In direct sunlight or next to heating equipment.
• Extremely cold or hot locations.
• Locations exposed to high humidity or excessive dust.
• Locations subject to strong shocks or vibration.
●
Before making any connections, make sure that the power on the
amplifier and any external devices is switched OFF.
●
To protect the speaker from possible damage, always set the
VOLUME knob to “0” before switching the power ON/OFF.
●
When connecting a speaker to this unit make sure to turn OFF the
power first.
●
Do not apply excessive force to the switches and controls.
●
Your Yamaha powered speaker is a precision musical instrument.
Handle it with care and avoid dropping or bumping it.
Precautions
●
Operating temperatures will rise during use. Make sure the ampli-
fier is used in a well-ventilated area. The AS60-112T should be
placed in a position were there is at least 30cm (12”) clearance
from the wall on the sides, top and back of the amplifier.
●
For safety, always remove the power plug from the AC wall outlet
if there is any danger of lightning striking in your area.
●
Keep the amplifier away from neon signs or fluorescent lighting to
prevent noise pickup.
●
To prevent damage and possibly electrical shock, never open the
case and tamper with the internal circuitry.
●
Never use benzene, thinner or other volatile liquids for cleaning, as
these chemicals may cause damage or discoloration to the finish.
Always use a dry, soft cloth to wipe off dust and dirt.

q
INPUT Jack (INPUT)
This is the AS60-112T’s INPUT jack.
Connect the instrument or the output from an external device to this
jack.
When using the Silent Violin, Viola, or Cello, use a standard monaural
plug cable to connect the LINE OUT jack on the instrument to this jack.
* Before making any connections, make sure that the power switch is set to
OFF.
w
Volume Control (VOLUME)
Controls the volume of the speaker.
e
Equalizer Switch (EQ ON/OFF)
This is the ON/OFF switch for the equalizer circuit (TREBLE, MIDDLE,
BASS). Set to ON (
>
), the equalizer circuit is active and the three knobs
r
can be used to adjust their respective frequencies. Set the switch to
OFF (
?
) if you want to produce only the direct sound created by the
instrument or external device, with no additional alteration.
r
Equalizer Controls (TREBLE, MIDDLE, BASS)
Controls the level of their respective frequencies. TREBLE (high fre-
quencies), MIDDLE (middle frequencies), BASS (low frequencies). When
set to “0”, the tone will be flat, rotate the knob to the left (minus) to cut
the frequency, and rotate to the right (plus) to boost the frequency.
t
Expansion Output Jack (LINE OUT)
The signal received via the INPUT jack is transmitted from this jack al-
though with its impedance converted (the signal also bypasses the equal-
izer circuit). When adding another powered speaker unit, such as an-
other AS60-112T, connect the additional unit to this jack.
y
Power Switch & Lamp (POWER)
This is the AS60-112T’s power switch. When the switch is depressed,
the lamp next to the switch will light.
* To protect the speaker from damage, always make sure that the Volume
Control
w
is set to “0” before the power is switched ON/OFF.
