IMPORTANT SAFETY INSTRUCTIONS
When using this electronic device, basic precautions should always be taken, including the following:
1. Read all instructions before using the product.
2. Do not use this product near water (e.g., near a bathtub, washbowl, kitchen sink, in a wet basement, or near a
swimming pool, etc.).
3. This product should be used only with a cart or stand that will keep it level and stable and prevent wobbling.
4. This product, in combination with headphones or speakers, may be capable of producing sound levels that
could cause permanent hearing loss. Do not operate for a long period of time at a high volume level or at a
level that is uncomfortable. If you experience any hearing loss or ringing in the ears, you should consult an
audiologist.
5. The product should be positioned so that proper ventilation is maintained.
6. The product should be located away from heat sources such as radiators, heat vents, or other devices
(including amplifiers) that produce heat.
7. The product should be connected to a power supply only of the type described in the operating instructions or
as marked on the product. Replace the fuse only with one of the specified type, size, and correct rating.
8. The power supply cord should: (1) be undamaged, (2) never share an outlet or extension cord with other
devices so that the outlet’s or extension cord’s power rating is exceeded, and (3) never be left plugged into
the outlet when not being used for a long period of time.
9. Care should be taken so that objects do not fall into, and liquids are not spilled through, the enclosure’s
openings.
10. The product should be serviced by qualified service personnel if:
A.
B.
The power supply cord or the plug has been damaged.
Objects have fallen into, or liquid has been spilled onto the product.
C. The product has been exposed to rain.
D. The product does not appear to operate normally or exhibits a marked change in performance.
E.
The product has been dropped, or the enclosure damaged.
11. Do not attempt to service the product beyond what is described in the user maintenance instructions. All
other servicing should be referred to qualified service personnel.

1. POWER SWITCH:
To turn the unit ON or OFF, press the upper or lower
portion of this button. The internal power LED illuminates
when the unit is turned “ON”. (Caution: Always turn the

PLEASE READ THIS MANUAL
BEFORE OPERATING THIS UNIT
Caution : To prevent malfunctioning
and/or possible equipment damage:
Before plugging the unit into the power
source: (1) the voltage selector switch
should be set for the correct voltage for
your area (115V or 230V) and (2) all
equipment connected to the crossover
outputs should be turned off or all the
inputs turned down.
the amplifier or transients harmful to the speakers may result.)
2. L/M/H OUTPUT LEVEL CONTROLS:
These are used to adjust the output level of each way: LOW, MID
and HIGH .
3. LOW CUT BUTTONS FOR LOW WAY:
These insert low cut filters in the LOW way of each stereo channel
with a 12dB/Octave, 30 Hz HPF to minimize problems from subsonic
frequencies in the signal, to suppress hum, and to prevent low fre-
quency speaker resonance.
4. MH CROSSOVER FREQUENCY CONTROLS:
These select the crossover frequencies of the MID and HIGH ways. They’re a low cut for the HIGH and a high
cut for the MID. You can select the frequencies between 480 Hz to 7 kHz.
5. LM CROSSOVER FREQUENCY CONTROLS:
These select the crossover frequencies of the LOW and MID ways. They’re a low cut for the MID and a high
cut for the LOW. You can select the frequency between 70 Hz to 1 kHz.
6. PHASE BUTTONS:
These allow switching the polarity to invert the signal phase on the MID and HIGH ways. This is done after the
output levels are set to correct audible phase problems.
Caution: Before pressing the PHASE BUTTON, always lower the outputs of your power amplifiers to avoid pos-
sible speaker damage.
7. SUB CROSSOVER FREQUENCY CONTROL:
This selects the crossover frequency of the SUB WOOFER way. You can select the frequency between 50 Hz to
250 Hz.
8. SUBWOOFER OUTPUT LEVEL CONTROL:
This is used to adjust the SUB WOOFER output level.
9. SUBWOOFER LOW CUT BUTTON:
This inserts a low cut filter in the SUBWOOFER way with a 12dB/Octave, 30 Hz HPF to minimize problems
from subsonic frequencies in the signal, to suppress hum, and to prevent low frequency subwoofer speaker
resonance.
