  The blue lamp illuminates while the unit is turned on.

  The lamp lights in green while the unit is turned on. When the lamp does not light or lights in 

red with the unit on, it indicates there may be any trouble (see "TROUBLESHOOTING"). 

  Turning this boosts the 45 Hz frequency within the range of 0 dB to +12 dB. Adjust the level 

while listening to the sound. This control is preset to MIN when the unit is shipped. 

  The input level can be adjusted with this control when this unit is connected to other source 

equipment. Adjust the level while listening to the sound. This control is preset to MIN when 
the unit is shipped.

CROSSOVER fi lter switch 
OFF:  Normally, set to this position. The switch is preset to this position when the unit is 

shipped. 

LPF:  Set to this position when you want to turn on the LPF (Low-Pass Filter) switch (the 

Low-Pass Filter transmits frequencies lower than the cutoff frequency).

HPF:  Set to this position when you want to turn on the HPF (High-Pass Filter) switch (the 

High-Pass Filter transmits frequencies higher than the cutoff frequency).

  Turning this adjusts the cutoff frequency within the range of 50 Hz to 400 Hz. Adjust the level 

while listening to the sound. This control is preset to 50 Hz when the unit is shipped.

•  Use a relay if your system employs too many amplifi ers. 
•  Confi rm the battery voltage (11 V to 16 V). 

The POWER/PROTECTOR lamp lights in red and/or the unit heats up abnormally. 
•  Use the speakers of suitable impedance.
•  Correct the speaker wirings if they are short-circuited.
•  Leave the unit turned off for a while to cool it down. 

No sound is heard. 
•  Confi rm the connections for power supply (see "POWER SUPPLY" on page 1).
