point where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid
injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in
any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does not operated normally, or has been dropped.

is set to "MONO/BTL". These jacks are not to be used
when the mode switch áD is set to "FIXED".
u INPUT Jacks (FIXED)
Used to connect the input signal to the amplifier.
Connect the jacks to the OUTPUT jacks on the preamplifier, etc.
One each cable can be connected to the [R] and [L]
jacks when the Mode switch t is set to "FIXED".

t is set to "VARIABLE" or "MONO/BTL".
i AC IN Jack
Used to connect the supplied AC power cable to the
amplifier.
Connect the other end of the AC power cable to
household AC outlet.
(Switch position: Right)
The amplifier works as a stereo power
amplifier (100W/8 ohms x 2 CH). Use
the INPUT jacks (FIXED) y as input
jacks.
The LEVEL adjustment knobs w on the
front panel are bypassed and inoperable.
(Switch position: Left)
The amplifier works as a monaural amplifier in BTL mode (300W/8 ohms x 1
CH). Use the [R] jack of the INPUT jacks
(VARIABLE) y as the input jack.
The input signal level can be adjusted
with the [RIGHT] knob of the LEVEL
adjustment knobs w on the front panel.

● Connection of the REMOTE POWER CONTROL Trigger
By connecting the REMOTE POWER CONTROL Trigger, the activation/deactivation of power on a Flying Mole
power amplifier equipped with REMOTE POWER CONTROL Trigger Input can be interlocked with the activation/deactivation of power on this device. Refer to the owner’s manuals of the devices to be connected as well
before connecting cables.
1.
Remove the attachment to the REMOTE POWER CONTROL connectors.
2. Remove insulation material around the ends of the supplied remote connection cables and twist the wires until they are stranded securely.
3. Insert the wires into the holes in the attachment and tighten the screws
to fix the cables.
* Connect the other ends of the cables to the connector for the device whose
power is to be interlocked as in the steps 1 to 3 above.
(The connector is also attached to the REMOTE POWER CONTROL jacks
of the device to be connected.)
4. DConnect the connectors to the REMOTE POWER CONTROL jacks of
the amplifier and of the other product.
•To control the power of the amplifier from the other product, connect the con-
nectors to the "IN" of this product and to the "OUT" of the other product.
•To control the power of the other product from this product, connect the con-
nectors to the "OUT" of the amplifier and to the "IN" of the other product.
* Commercially available vinyl insulated cables can be used as well. • Compatible cable type is AWG24 to AWG12.
Refer to the steps 1 through 4 above when connecting cables and make sure that the polarity is correct.

*Twist the wires of the speaker cable until they are stranded securely and take care not to leave any part of the stranded wires out
–
of the speaker connector when connecting the speaker cable. If the wires come in contact with the rear panel or the wires at the
positive terminal come in contact with the wires at the negative terminal, the protection circuit may be activated to stop the normal
operation of the product.

Caution
●
This product has DC amplifier circuit construction. (Sound signal goes through no capacitor from input to the speaker
output.)
Therefore, a little noise may be heard when the power is turned on or off depending on the connected device.
●
This product processes digital signals. This product may cause harmful interference to other equipment depending on
environments where they are used. If interference is caused, install the product where the interference is minimized.
In general, it is effective to keep the product as far away from the interfered equipment as possible. Bad receiving condition
may be experienced, especially if an indoor antenna or a feeder line is used for TV or radio broadcasting, because their
receiver sensitivity of airwaves tends to be low and is vulnerable to external influence. In such a case, an outdoor antenna
or a coaxial cable is recommended.

Never use liquids such as benzine, thinners,
etc., chemically treated cloths, and do not spray
any aerosol type insecticides on the amplifier.
Clean the case using only a soft, dry cloth.
If the amplifier becomes soiled, mix a solution
of water and a neutral detergent then dampen
a soft cloth in the solution, wring out as much
of the solution as possible, and clean the am-
plifier. Then use a soft, dry cloth to wipe the
Soft cloth
surface dry.
