Monitor XLR output, IFB 1 XLR output and IFB 2 XLR output.
IFB 3 and 4 XLR outputs will contain audio from phone line 2 (if active).

FAQ’s
? Can I connect a microphone to the input?
! No, the Monitor Send XLR input is a line level input so you cannot
use a microphone without a pre-amp. This input is for connection of a
line level audio signal only
.
? If I have the unit plugged in to an AC power source while I am
using it, will it recharge the battery?
! No, this device does not have a rechargeable battery. You should
only use an alkaline battery. Battery life will depend on how many
devices are connected and how the unit is being used.
? Can I talk to all four IFB outputs at the same time?
! No, the Monitor handset and Monitor Send XLR inputs can only be
connected to one IFB output at a time, using the Monitor selector
switch.
? I hear the called party on the handset but they can’t hear me.
! This unit was designed to work only with an electret-type handset.
Try using an AT&T, Sony or Lucent handset.
? Can I use the Four IFB to conference the phone lines together?
! No, the telephone lines cannot be bridged together on this device.
? How does each IFB line talk to the monitor?
! The IFB connectors are listen only. The four IFB outputs can be set
to receive audio from any of the four telephone lines but they cannot
send audio. Only the Monitor handset (or line level input from your
mixer, etc) can talk to the called parties on the telephone lines or to
the IFB outputs.
