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.
