Effective Date: 28 Jun 2021
The dual ICS connections may be used to allow the DZMx Plus to be connected to two
different audio panels on the aircraft, or to allow different audio connections to be used
simultaneously.
Mirroring Audio on Dual ICS Connections
If the DZMx Plus has connections to two audio panels but it is desirable to have the
same audio mirrored to both, select Mirror Audio to ICS2. Toggle slider to activate and
select
DONE
Providing for Modems to be Connected to Separate ICS Connections
The two ICS connections may be used to allow the DZMx Plus modems or connected
Bluetooth device to connect to separate ICS channels, allowing separate calls to occur
on the separate respective ICS channels.
Typically, this is used where ICS1 and ICS2 are connected to different audio positions
on the ICS.
Each of the modems and Bluetooth device may be allocated to either ICS1 or ICS2.
Simultaneous Calls
DZMx installations with more than one modem can make two calls simultaneously.
Making and receiving the first call works the same way as described above. However,
to make the second call, a long press is required to use the speed dial, phonebook, or
menu keys.
Note: While on two calls, both parties can hear you, but they are unable to hear each
other.
Call Priority
A modem which has been given priority will automatically mute all other calls when it
makes or receives a call. When a priority call has ended, it automatically unmutes any
other call. This can be particularly useful if a call on a modem is vital to vehicle aircraft
operations. By default, call priority is off, however it can be enabled using the "Call
Priority" setting for each modem in DZMx Connect. Go to Settings > Audio > Modems.
This option can be found in the settings under the audio section. This setting is
particularly useful for simultaneous calls on a single ICS channel.
Audio from the DZMx to the ICS
Audio from the DZMx Plus is connected direct to the ICS input, and its levels adjusted using
the DZMx Plus audio menu.
Audio from the ICS to the DZMx Plus (microphone installation)
The DZMx Plus can be installed in aircraft systems with either high impedance or low
impedance microphones. Most (but not all) civil aircraft operate high impedance (electret)
microphone systems. Refer to
microphone connections.
