Warning

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.

ATTENTION: RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR

An equilateral triangle enclosing an exclamation point is intended to alert the user to the presence of important operating and service instructions in the literature enclosed with this unit.

IMPORTANT SAFETY INSTRUCTIONS

WARNING-When using electric products, basic precautions should always be followed, including the following:

1.Read all the 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 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.

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.L/M/H OUTPUT LEVEL CONTROLS:

These are used to adjust the output level of each way : LOW, MID and HIGH .

3.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.

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.LH 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 SWITCHES:

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 switches, always lower the outputs of your power amplifiers to avoid possible 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 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.

10.AC CORD

11.L/M/H OUTPUT CONNECTORS:

Connect to your amplifiers via these balanced XLR output jacks.

12.STEREO INPUT CONECTORS:

Connect your L/R stereo input signal to these balanced XLR input jacks.

13.SUBWOOFER OUTPUT CONECTOR:

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 serviced by qualified personnel.
