MAIN OFF/ANTIPHONi\L ON CONTROLS
These tablets operate when an antiphonal speaker system is connected to your Rodgers Organ.
The basic concept of an antiphonal division is to place antiphonal speakers at the opposite end of the room from
the main sound source. This placement allows greater musical flexibility because the sound originates from either end of
the listening area, or from both ends simultaneously.
The MAIN OFF tab shuts off the sound of the main body of speakers, and the It\NTIPHONAL ON tab turns on the
auxiliary, or antiphonal
speakers.
NOTE: If the l\tIAIN OFF tab is depressed, the .ANTIPHONAL ON must also be depressed, or the organ will not sound
through either system.
TRANSPOSER
The Transposer will raise or lower the pitch of the organ four semitones (half-steps) in either direction. It is con-
trolled by a knob at the right hand side jamb. The Transposer is especially useful for accompanying, eliminating the need to
mentally transpose music on the printed sheet into a different key. Many singers need a key change to accommodate their
voice range, sometimes as far as amajor third in either direction. The Transposer accomplishes these key changes \vith the
touch of a piston.
Jt\nother important feature of the Transposer is that it returns to normal pitch (0 piston) automatically when the
organ is shut off,or when the combination action Cancel piston is pushed. This avoids the problem of the organ being in the
wrong key the next time it is played.
