To prevent shock hazard, all three connections must ALWAYS be used. Connect the MOON P-7 only to an AC source of the proper voltage; Both the shipping box and rear panel serial number label will indicate the correct voltage. Use of any other voltage will likely damage the unit and void the warranty AC extension cords are NOT recommended for use with this product.
Your new preamplifier is a true dual-mono design, whereby each channel operates completely independent of the other. The performance of your P-7 will continue to improve during the first 400 hours of listening. This is the result of a “break-in”...
In the event that the surface you have chosen isn’t perfectly level, each of the four (4) legs of both your P-7 are height adjustable; carefully using your fingers, you can either raise each leg by turning the cone underneath clockwise, or lower each leg by turning it counterclockwise.
2) engage the effects of the signal processor. The monitor component’s outputs must be connected to the P-7’s “Tape Monitor In” and its inputs must be connected to the P-7’s “Tape Monitor Out”.
Note: To change the balance between the left and right channels, please refer to the section “Remote Control Operation”. The “Input +” and “Input -” buttons allow you to choose which input source you wish to listen to. The MOON P-7 dual-mono preamplifier has a total of seven (6) inputs;...

(ii) exit from the Setup procedure by pressing the “Setup” button three times or (iii) continue with the Setup procedure and either assign the 12 Volt trigger outputs or reset the P-7 back to factory default status (see the following examples).

(continued) The MOON P-7 is equipped with two 12 Volt trigger outputs. When an input is assigned to a 12 Volt trigger, the device connected to the trigger will automatically start-up whenever you switch to that input. The default setting for all seven inputs is on.
Figure 2: Rear panel of MOON P-7 Preamplifier The rear panel of the MOON P-7 dual-mono preamplifier will look similar to Figure 2 (above). There are three rows of input and output connectors. On the top row is a full-function bi-directional RS-232 port control and status for custom integration or automation and uses a DB9 connector.
In the event that you plan to be away from your home for a few days, powering off the preamplifier may not be a bad idea. Once fully “broken-in”, please keep in mind that your P-7 will require several hours of playing time before it reaches its peak performance after you’ve powered it up again.
For example, when one conductor is carrying a signal of +10 Volts, the other will be carrying a signal of –10 Volts. When these two inverted signals on a balanced line are output from the MOON P-7, any noise picked up by the interconnect will be eliminated since a differential circuit amplifies only the difference between these two signals: Noise on a balanced interconnect will be equal on both conductors and therefore not be processed.
