APPLICATIONS
DynamicTalk is an elegant retractable system for gooseneck
microphones with exclusive features. It not only makes the microphone
disappear within the desk surface but it also provides a pleasant light
to indicate its status. Thanks to its protective and patented lighting
ring, the microphones can be safely stored and protected making
meeting and conference spaces more flexible and versatile.
DynamicTalk provides two different working modes: PA and
Conference. When in PA mode, a push button placed on the stainless
steel cover plate allows to activate or de-activate the microphone,
and the LED ring will indicate the status by changing colour from red
to green. The system will automatically silence the microphone when

9
retracting. When in Conference model, the microphone will always be
active and both the light ring and the access to the push button on
the cover plate will be available via GPI and GPO for remote control.
DynamicTalk is available in 3 sizes: for 400 mm, 500 mm and 600
microphones. The system can be adjusted to the exact length of the
microphone via AHnet and AHlink. The AHlink is an excellent tool to
diagnose, verify and configure DynamicTalk.
Features
• Universal lift system for gooseneck XLR 3 pin microphones
• Stainless steel cover plate with 3 buttons
• LED lighting ring to indicate microphone status, 360º
• Serial control and remote diagnosis

AHLINK
AHlink is used to control and set up the unit.
By default, the AHlink signal on the unit is deactivated. To activate the
AHlink signal, press during 2 seconds the Up/Down microphone button
located on the cover plate, or contact close GPI2 pin to GND during 2
seconds. When the AHlink signal is activated, 5 beeps will sound inside
the unit to indicate that the AHlink signal is active.
The unit automatically deactivates the AHlink signal if there is no device
(mobile or tablet) connected for more than 2 minutes. You can also
deactivate the AHlink signal using the APP on mobile or tablet. When
the AHlink signal is deactivated, a long beep sounds indicating that the
AHlink is not longer available on the unit.
To control and set up the unit using AHlink, download AHlink from the
App Store (IOS system) or from Google Play (Android system). The App
is free. Execute the AHlink on your mobile phone.
On the AHlink App options, it
is recommended to not select
Auto Connect and select Portrait
