IFB
If using the phone line or handset interface for an IFB feed, the bal-
anced male XLR output may be used to feed an IFB earpiece or
other device. If using the 1/4” cue input / wireless adapter jack for
the telephone connection, the IFB feed must be taken from one of
the 1/4” headphone jacks. This also applies if you are planning to
record both sides of the conversation while using the 1/4” wireless
adapter jack for the telephone connection.
Bluetooth Wireless Technology
While the mono audio path is easy to follow on the block diagram
shown on Page 16, the stereo audio path is slightly different. When
in stereo mode, the left and right audio paths from the Bluetooth
device are mixed together before reaching the Receive bus. This is
a full bandwidth (20 Hz to 20 kHz) mono path, so you will hear the
full audio signal, but it will be mixed to mono.
The transmit path is a bit more creative. The left channel of the
Bluetooth enabled stereo receive device will receive the mic mixer
output with a bandwidth of 20 Hz to 17 kHz. The right channel will
receive the Cue Input signal.
Keep in mind that cell phones do not offer transmission of stereo au-
dio signals. This stereo headset mode is typically “listen only” from
music player portables.
