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 located so that its location or position does not interfere with its proper ventilation.

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 and size and with the 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) be left plugged into the
outlet when left unused 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 when:
A. The power supply cord or the plug has been damaged; or
B. Objects have fallen into, or liquid has been spilled onto the product; or
C. The product has been exposed to rain; or
D. The product does not appear to operate normally or exhibits a marked change in performance; or
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.

ATTENTION: RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR

An equilateral triangle enclosing a lightning flash/arrowhead symbol is
intended to alert the user to the presence of uninsulated “dangerous
voltage” within the product’s enclosure which may be of sufficient
magnitude to constitute a risk of electric shock.

An equilateral triangle enclosing an exclamation point is intended to alert

Warning

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.

1. ON/OFF SWITCH
Caution: Always turn the Crossover ON before the amplifier, and turn it OFF after the amplifier or
transients harmful to the speakers may result .

2. CROSSOVER FREQUENCY CONTROLS:
These select the crossover frequencies of the LOW and HIGH ways.
They’re a low cut for the HIGH and a high cut for the LOW. You can
Select the frequencies between 250 Hz and 6 Hz.

3. L/H OUTPUT LEVEL CONTROLS:
These are used to adjust the output level of each way: LOW and HIGH .

4. LOW CUT SWITCHES 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
frequency speaker resonance.

10. STEREO INPUT CONECTORS:
Connect your L/R stereo input signal to either the balanced XLR or the unbalanced 1/4" input jacks.

11. OUTPUT CONECTORS:
Connect to your amplifiers via these unbalanced 1/4" output jacks.

12. AC VOLTAGE SELECTOR SWITCH:
Before plugging in the power cord, check to see that the unit is set for the proper voltage for your
area:~115V (60Hz) or ~230V (50Hz).

13. AC CORD

Specifications and design subject to change without prior notice for improvement purposes

5. PHASE SWITCHES:
These allow switching the polarity to invert the signal phase on the HIGH ways. This is done after
the output levels are set to correct audible phase problems.
Caution: Before pressing the PHASE switches, always lower the outputs of your power amplifiers to
avoid possible speaker damage.

6. 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.

7. SUBWOOFER OUTPUT LEVEL CONTROL:
This is used to adjust the SUB WOOFER output level.

8. SUBWOOFER LOW CUT SWITCHES:
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.
