1.
AC line input
– Connect the included IEC power cable.
2.
Network connector
– Connect one end of a Cat5e or Cat 6 cable to primary port, and the other to the
100/1000BaseT switch carrying audio (if a Dante-enabled model) traffic and control traffic. Note that a
single RJ-45 jack is used for both audio and control functions. However, these two functions each have
their own MAC address and IP address and therefore can be on the same network, or different
networks. The PC running the FLX-E application must be on the same network as the control port.
3.
Analog audio input connectors
– Connect balanced audio inputs here using the removable 3-pin 3.5mm
connectors provided. Note the polarity is ground-minus-plus from left to right for each of the four
available analog input channels. Single-ended inputs may also be used. See the diagrams below
illustrating proper connections for both balanced and single-ended sources.

4.
Remote volume control/mute/RS-232 connector
– Connect a 10KΩ potentiometer between the +10V,
RVC, and ground connection as shown in
. This volume control controls
all
local output
levels. A contact closure is also provided for fire alarms and other security systems. Ground the MUTE
pin to mute all local outputs. Audio will return at previously set levels when the short is removed. An
RS-232 controller can be connected between the TX/RX and ground pins. Refer to
for the
RS-232 command set.
Note that the FLX-E is a DCE device, that is, the transmit pin from the RS-232
