ENGLISH
“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.
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).
LOWPASS FILTER CONTROL
The JX monoblock employs a 12dB/octave
low-pass active filter for its internal channel. This
feature is designed to attenuate frequencies above
its filter frequency, so that the system’s subwoofers
do not reproduce any audible mid-range content.
The low-pass filter is fully variable between
50 Hz and 200 Hz via the Filter Frequency
control knob. 80 Hz (as shown in the diagram
below) is a good starting point for system tuning.
“PREOUTS”
The JX monoblock incorporates a pass-
through preamp output (Preouts) section,
designed to make multiple amplifier systems easy
to set up. This section consists of a pair of RCA-
type jacks marked “Preouts”.
These preamp outputs deliver the same signal
that is being fed to the Low-Level inputs. (If the
input signals are full-range, the preamp outputs
will be full-range). This signal is not affected by
the bass boost or Filter processing selected for the
amplifier.
IMPORTANT!
!
The "Preouts" of the JX250/1 and JX500/1D
will not pass signals from the Hi-Level inputs.
The JX1000/1D will pass signals from the
Hi-Level inputs and will attenuate them to
Low-Level.
