® Connect RM-RK130 to the REMOTE terminal on the amplifier with the remote cord
provided for RM-RK130. .
© RM-RK130 boosts the 45 Hz frequency within the range of 0 dB to + 18 dB. Adjust the level.
while listening to the sound.
The POWER lamp lights in green while
RM-RK130is turned on.
III Input LEVEL controller
The input level can be adjusted with this controller when this unit is connected to other source
equipment. Adjust the level while listening to the sound. This controller is preset to MIN when
the unit is shipped.
l!I LPF (Low-Pass Filler) controller
Adjust the cutoff frequency (the Low-Pass Filter transmits frequencies lower than the cutoff
frequency) within the range of 50 Hz to 300 Hz. Adjust the level while listening to the sound.
This controller is preset
to 50 Hz when the unit is shipped.
mPHASE switch
Select either normal (NOM) or reverse (REV), which reproduce a better sound. This switch is
preset
to NOM when the unit is shipped.
II BASS BOOST controller
Turning this boosts the 45 Hz frequency within the range at 0 dB to +18 dB. Adjust the level
while listening
to the sound. This controller is preset to MIN when the unit is shipped.
iii SUBSONIC filter controller
Adjust the cutoff frequency (the subsonic filter rejects frequencies lower than the cutoff
frequency) within the range of 20 Hz to 50 Hz. This controller is preset to 20 Hz when the unit
is shipped.
iii POWER/PROTECTOR lamp
The lamp lights in green while the unit is turned on. II the lamp does not light or lights in red
with the unit on, some trouble has occurred (see "TROUBLESHOOTING").
