Power Supply
Remove the lid of the battery
compartment and insert 6 AA
batteries, making sure that they are
correctly oriented.
* To avoid malfunction and/or
damage to speakers or other
devices, always turn off the
power on this unit and
disconnect any other devices when installing or replacing batteries.
* When closing the lid of the battery compartment, first insert the
catches on the lid into the matching cavities, then push the lid down
firmly until you hear a click.
Using Batteries
Please note the following points.
• If there are batteries in the unit while an AC adaptor is being used,
normal operation will continue should the supply of current
be interrupted (power outage or power cord disconnection).
• Use only alkaline batteries (LR6). You cannot use any other type of battery.
• Battery Life
Used continuously at maximum power: approx. 13 hours
(These figures will vary depending on the actual conditions of use)
• When operating on battery power only, the unit's power indicator (p. 6)
will become dim when battery power gets too low. Replace the batteries
as soon as possible.
• Sounds may distort easily or may cut off when played at high
volume as the battery power begins to fade, but this is normal
and does not indicate a malfunction. Either replace the batteries
or use the AC adaptor included with the unit.
1. Insert the DC plug of the supplied AC adaptor into the unit's AC
adaptor jack.
By anchoring the AC adaptor cord using the
cord hook, as shown in the illustration, you
can prevent situations such as the adaptor
becoming unplugged or unreasonable
pressure being exerted on the AC adaptor
jack.
* To avoid faulty operation or damage to the
speakers, you should disconnect the unit from other devices and
switch off its power when connecting the AC adaptor.
2. Connect the supplied power cord to the AC adaptor, and plug
it into an AC outlet.
Place the AC adaptor so the side with the indicator (see illustration)
faces upwards.
* The indicator will light when you plug the AC adaptor into an AC outlet.
Using the Unit With the AC Adaptor
Please note the following points.
• Although the unit can operate on batteries alone, connecting the AC
adaptor to the unit while it has batteries inserted ensures that power
is supplied from the AC adaptor, reducing battery consumption.
• Use only the AC adaptor included with the MICRO CUBE RX.
Use of other AC adaptors may damage the amp or result in other problems.
Once the connections have been completed, turn on power to your various
devices in the order specified. By turning on devices in the wrong order, you
risk causing malfunction and/or damage to speakers and other devices.
1.
Make sure that all volume controls on the MICRO CUBE RX
and connected devices are set to 0.
2. Turn on all the devices connected to the MICRO CUBE RX's INPUT
jack and AUX IN jack.
3. Turn on the MICRO CUBE RX.
4. Adjust the volume levels for the devices.
5. Before switching off the power, lower the volume on each
of the devices in your system, and then turn off the devices
in the reverse of the order followed when switching them on.
NOTE
Due to a circuitry protection feature, this unit requires a few moments
after power up before it is ready for normal operation. To avoid
sudden, high-volume sound, always make sure to have the volume
level turned down before switching on power.
NOTE
Even with the volume all the way down, you may still hear some
sound when the power is switched on and off, but this is normal,
and does not indicate a malfunction.
Attach the supplied strap to
the strap pin as shown in the
illustration.
NOTE
Attach the strap securely so that it does not easily become
detached. If the strap is loose, and you use it that way when
carrying the MICRO CUBE RX, the amp could be dropped,
possibly resulting in damage or injury.
NOTE
Use only the provided strap. The included strap is meant for
exclusive use with the MICRO CUBE RX. Do not use this strap
for other products.
NOTE
Do not spin or swing the MICRO CUBE RX while holding it by
the strap. This is extremely dangerous, as it may cause the strap
to become detached; or, if the motion is repeated enough, may
even break the strap.
