• Two types of input terminals are provided on the rear for input
connections.
( 1 ) 2P terminal (marked HOT, E)
It is provided for direct input (unbalanced, 10k ohms) without
using plug-in module. This terminal is directly connected with
a potentiometer inside.
(2) Plug-in module input
Select the desired module according to application.
• Plug the module into INPUT PORT, sliding it between the guide
rails, and secure with two screws.
• When INPUT PORT is not occupied, cover the PORT with the
blank panel, and secure it with screws.
•
Be sure that INPUT-LEVEL SWITCH is in the proper position
for the module used or the equipment connected to DIRECT
INPUT TERMINAL.
• When the P-906A or P-912A is used in combination with a mixer
preamplifier or serves as an incremental power amplifier, normally
