Setup & Maintenance
Setup:
To insure proper operation and to avoid potential safety
hazards, place the unit on a firm, level surface. Do not
plug or unplug the instrument or speaker cable while
the amplifier power is on. Rack-mounting this unit is
not recommended.
Heat & Ventilation:
For proper ventilation, make sure there is at least 8
inches (20cm) of clearance around the sides, top, back
and front of the amplifier. Avoid using in extremely hot
or cold locations and areas that are exposed to direct
sunlight, or near heating equipment. The heat sink fins
and ventilation slots that form part of the enclosure are
specially designed to displace heat generated by the
amplifier. Placing other electronic equipment near these
heat-dissipation systems may possibly affect the long-
term reliability of both your amplifier and the other equip-
ment.
Moving the Unit:
Before moving the unit, be certain to disconnect all cables.
Make sure that you disconnect the unit from the AC
outlet. If Traveling with the unit frequently, we recom-
mend a road case or gig bag to protect it from scratches
and road wear.
Cleaning & Maintenance:
Clean only with a dry cloth. Never use benzene, thin-
ner, alcohol, or other volatile cleaning agents. Do not
use abrasive cleaners, as they may damage the finish
of metal parts. Avoid spraying insecticides near the
unit. No other maintenance should be necessary.
MicroBass-III Series
Quick Start
Plug It In:
Set the power switch to Off and connect the supplied
power cord, from the amplifier's AC receptacle, to an
AC power outlet of proper voltage and power rating
(see safety information on page 3 for details).
Connect Your Cabinets:
Connect your external speaker cabinets to the ampli-
fier outputs marked SPEAKER OUTPUTS. If you
are using two 8 ohm or one 4 ohm external cabinet
with an MB Series combo, turn the internal speaker
off by pressing the switch out. Be sure not to exceed
the recommended speaker load below.
Maximum Recommended Speaker Loads:
EXTERNAL
SPEAKER(S)
1 x 8 ohms
1 x 4 ohms
2 x 8 ohms
If you are using a Gallien-Krueger HMS (Horn Man-
agement System) compatible speaker cabinet, set the
cabinet's bi-amp switch to Full Range.
Initial Front Panel Control Settings:
Set all EQ controls and the Boost control to 12 o'clock
(The MBS does not have a boost control). The Voic-
ing Filters should be turned all the way down to get a
flat response. Set the Input and Master Volumes at 0.
Connect Your Bass:
Using an instrument (shielded) cable, connect your bass
to the Input jack and press the power switch on.
Input and Master Volume Settings:
Set the master to 12 o'clock then gradually increase
the preamp volume control to a comfortable listening
level. If you hear distortion at low volume settings, try
pressing in the -14dB pad. If it's still distorted, try
turning the volume down on your bass.
