"BASS BOOST" CONTROL
The JX monoblock includes a single band,
boost-only bass equalizer controlled by a rotary
knob marked "Bass Boost". This control has a
boost range of 0dB (full-counterclockwise) to
+12dB (full-clockwise) and is centered at 45 Hz.
JX250/1D • JX500/1D • JX1000/1D
REMOTE LEVEL CONTROL
With the optional RBC-1 Remote Level
Control (sold separately), you can control the
subwoofer volume from the front of the vehicle.
The RBC-1 connects to the jack
labeled "Remote Level Control" on the
Connection Panel of the JX Monoblock
amplifier, using a standard telephone
cable (supplied with the RBC-1).
When connected to the amplifier, the
Remote Level Control operates as follows.
At full counter-clockwise rotation, the audio
will mute completely. At full clockwise
rotation the level will be the same as if
the RBC-1 was not connected at all. In
other words, it operates strictly as a level
attenuator. This control will not affect the
"Bass Boost" feature of the JX Monoblock.
Care should be taken to securely mount this
control in a manner that does not interfere with
vehicle operation.
When setting the amplifier's input sensitivity,
the Remote Level Control should be unplugged or
at full clockwise rotation (maximum level).
