Preouts
The XD600/1 incorporates a pass-through
preamp output section, so that additional
amplifiers can be easily added to the system.
The preamp output delivers the same signal that
is connected to the XD600/1’s inputs.
The preamp output signal by any crossover
filter selected (if the input signal is full-range, the
preamp output will be full-range).
If you plan to use the “Preouts” 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.

The XD600/1 is designed to deliver power into
subwoofer loads equal to or greater than 2 ohms.
The XD600/1’s subwoofer outputs are
designed to accept 16 AWG - 8 AWG wire. To
connect the subwoofer 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.
You will notice that there are two “+” positive
connections and two “–” negative connections.
This is to facilitate multiple subwoofer wiring.
The two positive and two negative connections
are connected in parallel inside the amplifier
They are not stereo outputs. Connecting two
subwoofers, each to one set of positive and
negative terminals, will result in a parallel
subwoofer connection. If only connecting one
pair of subwoofer wires, it is not necessary to use
both sets of connections.
Subwoofer loads below 2 ohms nominal are not
recommended and may cause the amplifier
to initiate a protection mode which reduces
power output.
