SPEAKER OUTPUTS

The JX400/4D's speaker outputs are designed
to accept 16 AWG - 8 AWG wire.
Each pair of the JX400/4D's channels are
designed to deliver power into speaker loads equal
to or greater than 2 ohms per channel when using
a "stereo" configuration and speaker loads equal
to or greater than 4 ohms per bridged pair of
channels when using a "bridged" configuration.

Speaker loads below 2 ohms nominal per
channel are not recommended and will cause
the amplifier to enter a protection mode.
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 JX400/4D has been designed
for bridging of its channel pairs without the need
for input inversion adaptors.
To bridge a pair of channels, use the
"Left +" and "Right –" speaker connectors only
(the "Left –" and "Right +" remain unused).
When bridged, each channel will deliver
optimum power into a 4 ohm load.

When a pair of JX400/4D channels are
bridged, they will deliver 200W x 1 into a 4
ohm load or 140W x 1 into an 8 ohm load.
Operating a pair of bridged channels into a
load lower than 4 ohms is not recommended
and will cause the amplifier to enter a
protection mode.

Any bridged channel pair must be fed by both
Input Channels corresponding to it (Left and
Bridged
Right). Failure to do so will result in significant
audible distortion.
When a pair of the JX400/4D's channels are
operating in bridged mode, the output will be in
mono (only one channel). This mono channel
can contain right channel only information,

left channel only information or the sum of
the information from both the right and left
channels. In order to achieve one of these options,
configure the inputs to that pair of channels in
one of these two ways:
1) Left Channel Only or Right Channel Only
Information: If you wish to send a left-only
or right-only signal to a pair of the JX400/4D's
channels, use a "Y-Adaptor" to split the single
channel signal into both left and right RCA
inputs. This option is useful when using a
pair of the JX400/4D's channels to drive left
channel speakers only and the other pair of
the JX400/4D's channels to drive right channel
speakers only.
2) Left + Right Channel Information:
When bridged and fed by a stereo input, a pair
of the JX400/4D's channels will automatically
combine the left and right channels into a
summed mono (left + right) channel. This
option is useful when using a pair of the
JX400/4D's channels to drive a subwoofer
system or a summed mono center channel.
