ECHO ORGAN EQUIPMENT FOR THE HAMMOND ORGAN
An echo tone cabinet (or group of cabinets) may be used with any type of Hammond
Organ console. The echo cabinet is usually placed at some distance from the console
and from the main cabinet; for instance, at the opposite end of a church. An echo
switch mounted on the console enables the organist to play through the main cabinet
alone, the echo cabinet alone, or both together. Any standard Hammond tone cabinet
may be used.
The echo switch has three positions. When it is set to the left the main tone
cabinet (or cabinets) will sound, and when set to the right the echo cabinet will
sound. With the switch in the center both main and echo will sound simultaneously.
The switch controls only the signal circuits, and all cabinets remain energized as
long as the console is turned on.
Figures 1 and 2 show how the main and echo tone cabinets are connected to the
console. and figure 3 is a schematic circuit of the echo system.

The echo kit includes all necessary parts for installation in consoles Models B, BC,
BCV, BV, C, CV, D, DV, G, RT, B-2, C-2, RT-2, B-3, C-3, & RT-3, with the exception

A 5-conductor cable must be ordered separately, of suitable length to reach from the
console to the echo cabinet, in addition to the desired echo cabinet (or cabinets).
