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  
Crossover ON before the amplifier, and turn it OFF after  
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. Theyre 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. Theyre 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.

10. POWER CONNECTOR  
The IEC jack is used to connect the power cord to the AC Power Source.  
(Caution: Do not remove the center grounding pin.)  
11. L/M/H OUTPUT CONNECTORS:  
Connect to your amplifiers via these balanced XLR output jacks.  
12. BALANCED INPUT CONNECTORS (Combo 1/4TRS & XLR):  
Connect your L/R stereo input signal to these balanced combo jacks. These combination 1/4TRS (Tip/Ring/Sleeve)  
phone jacks and XLR jacks are compatible with either type balanced connector and are wired as Tip/Pin 3 = (+),  
Ring/Pin 2 = (-), and Sleeve/Pin 1 = Ground.  
13. SUBWOOFER OUTPUT CONNECTOR:  
Connect to your subwoofer amplifier via this balanced XLR output jack.  
14. 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).  
15. FUSE COMPARTMENT :  
Replace with only the same type fuse (0.5A/250V). If it blows continuously, do not use the unit until it has been serv-  
iced by qualified personnel.
