Controls
On upper cover plate, there are tree push buttons to control the functions
and to external control other devices (GPO).
1. DOWN: Control the down microphone lift movement
2. Customized: The central push button, is used to control external
devices. The contact close button (GPO) is present on SubD9
connector to external control other devices
3. TALK or GPO: The third push button has two different functions
PA mode: Working in PA mode, this button is used as MUTE
function. Press one time the button, the ring LED goes to red
indicating that the mute is not active and you can talk to the
audience. Press once the button, the ring LED change to green
indicating that the MUTE is active and the microphone is not
working
Conference mode: In conference mode, the microphone is
controlled by the external conference system. Then, this button
has no function and the contact close of the push button is present
on the SubD9 control connector (GPO). In this case, there are two
GPO buttons available
-Dynamic ring LED: The system has a ring LED to indicate the status of
the microphone: RED the MUTE is not active, and GREEN the MUTE is
active. When the equipment is configured to work as conference mode
the RING LED is external controlled by GPI on the SubD9 external
control connector

the last device of the RS422 bus
-AHnet: RJ45 CAT5 connector for addressable RS422 control. There is a
loop through connector to use as signal RS422 output. You can
connect up to 30 units on the same RS422 bus
-AHnet ADDRESS: Using the AHnet protocol, this is the number of the
device into the RS422 addressable bus
Microphone length setting procedure.
Dynamic Talk is designed to work with microphones of different lengths.
Two signs to identify an incorrect setup of the microphone length are:
•The microphone do not goes down completely.
•The microphone goes down too low, and gets stucked inside. The
microphone length can be adjusted using Monitor Configurator Tool, but
there is a quick procedure not requiring the PC and the cabling
PROCESS
1. Disconnect Power connector
2. Set switch 5 to ON position
3. Set the length of the microphone in the rotatory
switch, in cm. For instance, if the microphone is
40cm, set the rotatory switch as: tens=4, unit=0)
4. Connect Power , there will be a 5 beep sound
5. Disconnect Power
6. Set switch 5 to OFF position
7. Set the AHnet address in the rotatory switch,
the default setting is address 01 (tens=0, units=1).
8. Connect Power connector
