System Description
APPLICATIONS
The DynamicTalk system is a universal motorised microphone lift system
remotely controllable through RS 422 or GPI with a Dynamic LED Ring for
“ready to talk” and “talk” indications.
DynamicTalk is an universal XLR microphone lift. Also available in a
customised version for all types of conference microphones systems.
FEATURES
– Universal microphone lift system
– Two different modes of operation: PA (public address) or conference
(controlled by external conference system control)
– Up / Down mechanical function controlled by push button on cover plate,
and external control by AHnet protocol (RJ45) or external contact close. The
AHNET is an addressable RS422 protocol to externally control the equipment
– Dynamic LED Ring for “ready to talk” and “talk” indications
– Push button on upper cover plate to use externally (GPO)
– Push button to MUTE function in PA mode, or to use as GPO in conference
mode
– In PA mode, the microphone is muted when it is down
– AHDT LS: for microphones with a maximum length of 400 mm, including
connector and foam windscreen*
– AHDT LM: for microphones with a maximum length of 500 mm, including
connector and foam windscreen*
– AHDT LL: for microphones with a maximum length of 600 mm, including
connector and foam windscreen*
* Total microphone lenght must take into account the connector and foam windscreen

Controls
UP & DOWN MOVEMENT
On the upper cover plate, there are three buttons to control the functions and
to external control other devices (GPO).
1. UP/DOWN: Controls the elevation and retraction of the microphone lift.
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: In PA mode this button is used as MUTE function. Press the
button once and the LED ring will appear in red indicating that the MUTE
function is deactivated and it's ready for the user to talk to the audience.
Press the button again to activate the MUTE function and silent the
microphone, which will be indicated by the green LED ring.
• Conference mode: In Conference mode the microphone is controlled
by the external conference system. This button then, 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.
4. Dynamic LED Ring: The system has a LED Ring to indicate the status of the
microphone: RED indicates that the MUTE function is deactivated and GREEN
indicates that the MUTE is activated. When the equipment is configured to
work on Conference mode, the LED Ring is externally controlled by GPI on
the SubD9 external control connector.

MICROPHONE LENGTH SETTING PROCEDURE
DynamicTalk 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 slowly, and gets stuck inside.
The microphone length can be adjusted using the Monitor Configurator
Tool, but there is also a quick procedure that doesn’t require the use of a
PC and cable:
1. Disconnect the 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 to 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 the Power connector

Product Handling
Please follow the figure below for a correct product usage of the DynamicTalk
microphones.
To avoid any product malfunctions, do not attempt to bend the microphone
to the incorrect angle or outside the microphone's working area.
Please note that ware to the microphone and pop screen surface can
occur.
