10 | JL Audio - XD500/3v2 Owners Manual
Note: In any of the three modes, the preamp
output signal is not affected by any crossover
filter selected (if the input signal is full-range, the
preamp output will be full-range).
Note: When the “Input Voltage” switch is in its
“Low position, the level of the “Preouts” signals
matches the input signal levels (unity gain). When
the “Input Level” switch is in the “high” position,
the level of the input signal is attenuated –12 dB
to produce a line level signal at the “Preouts”.
This ensures a proper line level signal output
under both conditions.
SPEAKER OUTPUTS
The XD500/3v2’s speaker outputs are designed
to accept 16 AWG - 8 AWG wire. To connect the
speaker wires to the amplifier, first back out the
set screws on the top of the terminal block, using
the supplied 2.5 mm hex wrench. Strip 1/2 inch
(12 mm) of insulation from the end of each 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 place, tighten the set
screw firmly, taking care not to strip the head of
the screw.
The XD500/3v2’s main channels are designed to
deliver power into speaker loads equal to or greater
than 2 ohms when using a “stereo” configuration
and speaker loads equal to or greater than 4
ohms when using a “bridged” configuration. The
subwoofer channel is designed to deliver power into
subwoofer loads equal to or greater than 2 ohms.

Bridged Mono Subwoofer Output
Speaker loads below 2 ohms nominal per
channel (or 4 ohms bridged) are not
recommended and may cause the amplifier
to initiate a protection mode which reduces
power output.
BRIDGING CONSIDERATIONS
Bridging is the practice of combining the
output of two amplifier channels to drive a single
load. When bridged, each channel produces
signals of equal magnitude, but opposite polarity.
The combined output of the two channels
provides twice the output voltage available from a
single channel. The XD500/3v2 has been designed
for bridging of its main channel pairs without the
need for input inversion adaptors.
To bridge the main channels, use the
“Left +” and “Right –” speaker connectors
only (the “Left –” and “Right +” remain
unused). The bridged channel pair will
deliver optimum power into a 4 ohm load.
When a the XD500/3v2’s main channels are
bridged, they will deliver 200W x 1 into a 4 ohm
load or 150W x 1 into an 8 ohm load. Operating
the bridged channels into a load lower than 4
ohms is not recommended.
A bridged pair of channels requires that both
channels in the pair receive input. You must
connect the mono or stereo source signal to
both the left and right inputs of the bridged
channel pair. Connection of only one input will
result in reduced power output, increased
distortion and can cause the amplifier to
overheat. Do not do this!
When the pair of the XD500/3v2s main
channels are operating in bridged mode, the
output will be in mono (only one channel). This
mono channel can contain only right channel
information, only left channel information, or
the sum of the signals from right and left input
channels. In order to achieve one of these options,
configure the inputs to that pair of channels in
one of these two ways:
