Hammond Model A, Manual, Page: 62 / 298

CABLES
Each console is shipped from the factory with cables sufficient for an
ordinary installation having a single tone cabinet. It has a 15 foot 2 conductor
line cord for connecting to an AC wall outlet, and a 35 foot console-to-cabinet
cable (6 conductor or 5 conductor, depending on the console model) to connect
to the first power amplifier. In case the console is located an unusually long
distance from the tone cabinet, additional 6 or 5 conductor cable must be
ordered. If the console has an echo switch, a 5 conductor cable of the required
length must be ordered separately to connect it to the echo tone cabinet. (See
Echo Organ Wiring, on page 3 of this section).
For installations having two or more tone cabinets, cable suitable in length
must be secured to connect between cabinets. Each power amplifier has a 6
pole input plug and a 5 pole coupling receptacle for connecting additional
amplifiers.
TYPES OF CABLES USED
6 Conductor console-to-cabinet cable used onion models A, B, AB, BC,
BCV, BV, C, CV, D, DV, E, G, RT. This is used only between these models
of consoles and the first power amplifier, and has a 6 pole plug at one end and
a 6 pole receptacle at the other. It consists of two AC wires, two grid (signal)
wires, a B plus wire to carry plate current from the first power amplifier to
the console preamplifier, and a ground (signal return) conductor, which is
actually a shield over the B plus wire. This cable is especially designed for
use with the Hammond Organ and is approved by the Underwriters Laboratories
for that purpose.
5 Conductor console-to-cabinet or cabinet-to-cabinet cable. This is identical
to the 6 conductor cable except that it has no shield and one end has a 5 pole plug
instead of a 6 pole plug. It has no B + conductor, the fifth wire being used for
ground. It is used for carrying power and signal between amplifiers, since a B +
connection is never needed beyond the first power amplifier; to connect an
echo cabinet, since in this case also no B + connection is required; and as a
console-to-cabinet cable for models where the console preamplifier has its own
power supply. In case 5 conductor bulk cable is not available, a 5 conductor cable
assembly may be made from 6 conductor bulk cable, using the shielded wire for
ground and leaving the shield disconnected. NOTE: 5 conductor console -to-cabinet
cable is used with Models B-2, B-3, C-2, C-3, RT-2, RT-3, A-1OO, and D-100.
3 Conductor cabinet -to -cabinet cable. This is used for carrying only the
signal between amplifiers, and is used for connecting cabinets when external AC
power circuits are employed. It is standard 3 conductor indoor telephone cord
and has 5 pole plugs on both ends. A cable may be made up with a number of
plugs along its length in order to connect several cabinets together. This wire
can be secured from your local electrical jobber.
