Remote Turn-On - JL Audio Slash v2 1000/1V2 Owner's Manual

remote turn-on

The 1000/1v2 uses a conventional +12V remote
turn-on lead, typically controlled by the source
unit's remote turn-on output. The amplifier will
turn on when +12V is present at its "Remote"
input and turn off when +12V is switched off. If
a source unit does not have a dedicated remote
turn-on output, the amplifier's turn-on lead can
be connected to +12V via a switch that derives
power from an ignition-switched circuit.

insert the bare wire into the receptacle on the
front panel of the amplifier, seating it firmly so
that no bare wire is exposed. Smaller wire than
12 AWG can be used, but it may be necessary
to strip 1 inch of insulation from the wire and
fold the bare wire in half prior to insertion.
While holding the wire in the terminal, tighten
the set screw firmly, taking care not to strip
the head of the screw and making sure that
the wire is firmly gripped by the set screw.

The 1000/1v2 employs a differential-balanced
input topology that provides the user with a high
degree of input flexibility while retaining superior
noise rejection. This type of circuit also allows
the 1000/1v2 to accept high-voltage inputs from
factory source unit outputs without excessive
distortion or noise problems.

1) Input Connections: A standard left/right pair
of RCA type jacks is used for input on
the 1000/1v2. You may run a stereo or a mono
signal into the inputs of the amplifier. The
amplifier's input section automatically sums
stereo signals to mono for the internal
amplifier section and for the "LP" "Filter
Mode" of the "Preamp Output" section.
!
IMPORTANT
If you plan to use the "Preamp Output" in
"Full-Range" or "HP" mode to feed a stereo
amplifier, you must connect a stereo signal to
the input of the amplifier. A mono signal into
the amplifier will result in a mono signal out of
the preamp output. (It's a great amplifier, but it
doesn't do magic).
The amplifier will operate with only one input
connection (left or right), but will require an
increase in input sensitivity to overcome the loss
of signal. If a mono input signal is to be run, we
recommend that you use a "Y-adaptor" like the
JL Audio ECS model XB-CLRAICY-1F2M to split
the mono signal into both inputs of the amplifier.
2) Input Voltage Range: A wide range of signal
Subwoofer Output input voltages can be accommodated by
the 1000/1v2's input section (200mV – 8V).
This wide range is split up into two sub-
ranges, accessible via switches located in the
"Amplifier Input Section" of the amplifier.
MONO OUTPUT ONLY
The "Low" position on the "Input Voltage"
switch selects an input sensitivity range
between 200mV and 2V. This means that
the "Input Sens." rotary control will operate
within that voltage window. If you are using
an aftermarket source unit, with conventional
preamp-level outputs, this is most likely the
position that you will use. The "High" position
on the "Input Voltage" switch selects an input
sensitivity range between 800mV and 8V. This
is useful for certain high-output preamp level
signals as well as speaker-level output from
source units and small amplifiers. To use
speaker-level sources, splice the speaker output

IMPORTANT
The output of the amplifier will decrease
for a given input voltage when the "Input
Range" switch is placed in the "High" position.
Conversely, the output will be higher with
the switch in the "Low" position. While this
may sound counter-intuitive, it is correct
as described.
3) Input Sensitivity Adjustment: Located
next to the "Input Voltage" switch, in the
"Amplifier Input Section", is a rotary control
labeled "Input Sens.". Once the appropriate
"Input Voltage" range has been selected, this
rotary control can be used to match the source
unit's output voltage to the input stage of the
amplifier for maximum clean output. Rotating
the control clockwise will result in higher
sensitivity (louder for a given input voltage).
Rotating the control counter-clockwise will
result in lower sensitivity (quieter for a given
input voltage). To properly set the amplifier
for maximum clean output, please refer to
Appendix A (page 14) in this manual. After
using this procedure, you can then adjust
the level of the amplifier by adjusting the
input sensitivity downward, if the amplifier
requires attenuation to achieve the desired
system balance. Do not increase the "Input
Sens." setting for any amplifier in the system
beyond the maximum level established during
the procedure outlined in Appendix A (page
14). Doing so will result in audible distortion
and possible speaker damage.
