Rear Panel Controls and Functions

IFBT4 Rear Panel
XLR Jack
A standard XLR female jack accepts a variety of input sources depending on the
setting of the rear panel MODE switches. XLR pin functions can be changed to
suit the source depending on the positions of the individual switches. For detailed
information on the setting of these switches see the owner's manual.
MODE Switches
The MODE switches
allow the IFBT4 to ac-
commodate a variety
of input source levels
by changing the input
sensitivity and the pin
functions of the input
XLR jack. Marked on
the rear panel are the
most common settings.
Each setting is detailed
in the chart. Switches
1 and 2 adjust the XLR
pin functions while
switches 3 and 4 adjust
the input sensitivity.

Power Input Connector

The IFBT4 is designed to be used with the DCR12/A5U external (or equiva-
lent) power source. The nominal voltage to operate the unit is 12 VDC,
although it will operate at voltages as low as 6 VDC and as high as 18 VDC.
External power sources must be able to supply 200 mA continuously.

Antenna

The ANTENNA connector is a standard 50 ohm BNC connector for use with
standard coaxial cabling and remote antennas.
