The preset panel is a set of terminals which allows the user to rewire the C# through A presets. This panel is accessed from behind the organ.

Here's a picture of a preset panel:

(Often, a little cloth bag of screws (for altering the presets) is found hanging on the preset panel.)

+
+!! Changing the Preset
+
+The organs which have preset panels came with a card with instructions on how to change the presets,
+and which had a spreadsheet on which one could note the currently wired-up preset settings.
+A scan of this card is available in the [A-100 manual|http://www.theatreorgans.com/hammond/faq/a-100/a-100.html] (figure 17)
+The text of the card follows~:
+
+ <b>Preset Panel</b>
+
+ The tone signals from the preset keys are carried by color-coded wires to the divided preset panel in the back of the console.
+
+ Each preset wire, carrying a single harmonic, is fastened under a screw on the bar which represents the desired intensity of that harmonic.
+ This is equivalent to setting a harmonic drawbar to the corresponding number.
+ One part of the preset panel is used for the swell (upper) manual and the other for the great (lower) manual and pedals.
+
+ When shipped each organ has its presets set up as shown in the playing instructions furnished with the organ.
+ Preset combinations may be changed at will by removing the console back and following the directions on a card inside.
+ This card is reproduced below. (Figure 17)
+
+ <b>Directions for Making Pre-Set Panel Connections</b>
+
+ There are 9 color-coded wires threaded through one of the lower holes for each pre-set key.
+ Above each hole are 9 binding posts arranged in vertical order,
+ and above the uppermost binding post is a name plate specifying the pre-set key associated with the row of wires below.
+ The lowest binding post is that of zero strength and corresponds to a harmonic control pushed all the way in.
+ The uppermost binding post is of 8 strength and corresponds to a harmonic control drawn all the way out.
+ The bus-bar strips for each level are extended to the left where they are marked with their appropriate strength numbers.
+ For example, suppose the combination 006523411 is to be set up on the D# of the upper manual.
+ It will be found helpful, especially when setting several combinations, to use the follow chart:—
+
+ <?plugin OldStyleTable
+ | Manual | Key | Brown | Red | Orange | Yellow | Green | Blue | Violet | Grey | White
+ | Upper | D# | 0 | 0 | 6 | 5 | 2 | 3 | 4 | 1 | 1
+ | | | | | | | | | | |
+ | | | | | | | | | | |
+ ?>
+
+ With a screw driver remove the connections already made on the D# "Upper Manual" row of binding posts
+ and separate the 9 wires from each other.
+ Referring to the chart above, the brown and red wires are twisted together and connected with the binding post
+ on the level marked "0" (lowest level).
+ Next the white and grey wires are inserted under the binding post on the level marked "1".
+ Similarly, the green wire is connected on level "2," the blue wire on level "3,"
+ the violet wire on level "4," the yellow wire on level "5,"
+ and the orange wire on level "6."
+ The binding posts should be firmly tightened over the wires to insure good electrical contacts.
+
+ <?plugin OldStyleTable
+ |||^ *Color Code Explanations*
+ ||| Each group of 9 wires is color-coded as follows:
+ | Sub-fundamental | (brown drawbar) | brown wire
+ | Sub-3rd harmonic | (brown drawbar) | red wire
+ | Fundamental | (white drawbar) | orange wire
+ | 2nd Harmonic | (white drawbar) | yellow wire
+ | 3rd Harmonic | (black drawbar) | green wire
+ | 4th Harmonic | (white drawbar) | blue wire
+ | 5th Harmonic | (black drawbar) | violet wire
+ | 6th Harmonic | (black drawbar) | grey wire
+ | 8th Harmonic | (white drawbar) | white wire
