INPUT SECTION
The XD200/2v2’s input section allows you to
send signals to the amplifier section through the
use of two differential-balanced inputs.
Input connections are via up to one pair of
traditional RCA-type jacks.
Input Voltage Range:
Input Voltage Range: A wide range of signal
input voltages can be accommodated by the
XD200/2v2’s input section (200mV – 8V). This
wide range is split up into two sub-ranges,
accessible via the “Input Voltage” switch:
“Low”: for preamp level signals
“High”: for speaker level signals
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 the position you should select.
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 wires of the source unit or small
amplifier onto a pair of RCA cables or plugs,
or use the JL Audio ECS Speaker Wire to RCA
adaptor (XD-CLRAIC2-SW).
Line output converters are usually not needed
with the XD200/2v2. If you find that the output
cannot be reduced sufficiently with a direct
speaker level signal applied to the amplifier and
the “Input Voltage” switch in its “High” position,
you may use a line output converter or voltage
divider to reduce the signal level.
