Turn-On Lead; Input Section - JL Audio NexD M1000/1v2 Owner's Manual

TURN-ON LEAD

The M1000/1v2 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.
The M1000/1v2's "Remote" turn-on connector
is designed to accept 18 AWG – 12 AWG wire. To
connect the remote turn-on wire to the amplifier,
first back out the set screw on the top of the
terminal block, using the supplied 2.5 mm hex
wrench. Strip 1/2 inch (12mm) of wire and insert
the bare wire into the terminal block, seating it
firmly so that no bare wire is exposed. 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.

INPUT SECTION

The M1000/1v2's input section allows
you to send signal to the amplifier section
through the use of two differential-
balanced inputs, one for the left channel
signal and one for the right channel signal.
Connection is via RCA-type jacks.
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. 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" to split the mono
signal into both inputs of the amplifier.
Input Voltage Range:
The M1000/1v2's input section is designed to
accept signal voltages from 100mV – 4V. This
will accommodate all preamp level signals and
many speaker level signals.
To use speaker-level sources, simply splice the
speaker output wires of the source unit onto a
pair of RCA plugs for each input pair. (or use
JL Audio part XD-CLRAIC2-SW) No "line
output converter" is needed in most cases.
If you find that the output cannot be reduced
sufficiently with a direct speaker level signal
applied to the amplifier, you may use a "line
output converter" or voltage divider to reduce the
signal level.
