TURN-ON LEAD
The XD700/5 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 XD700/5’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 2.5mm 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 (not the
insulation) is firmly gripped by the wire clamp in
the terminal.
INPUT SECTION
The XD700/5’s input section allows you to send
signals to the amplifier section through the use
of two, four or six differential-balanced inputs.
Input connections are via up to three pairs of
traditional RCA-type jacks.
If you wish to send six discrete channels into
the XD700/5, simply use all six inputs and set the
“Input Mode” switch in the “6 Ch.” position. The
amplifier will automatically combine the Sub Ch.
input signals to mono.
If you prefer to use only four channels of input
into the XD700/5, set the “Input Mode” switch
in the “4 Ch.” position and use the Ch 1 & 2 and
Ch 3 & 4 Inputs. In this mode, the XD700/5 will
derive its subwoofer channel signal from a sum
of all four input signals. The bass will not fade
when the signal is faded by the head unit from
front to rear.
You may also choose to apply only two
channels of input to deliver signal to all five
amplifier channels. To do this, set the “Input
Mode” switch to “2 Ch.” and use only the inputs
to channels 1 & 2. In this mode, Channel 3 will
operate with the Channel 1 signal and Channel
4 will operate with the Channel 2 signal. The
amplifier will automatically combine the main
input signals to mono for the Subwoofer Channel.
