INTRODUCTION
The ONE-PTT dynamic microphone adds more versatility to your ONE unit.This new

inside the unit, you do not need to add an external power supply. With the
included microphone stand, you can hang this microphone to the ONE 500 side
for a fast and easy call. You can also fix it to any other surface following
your preferences.
DESCRIPTION
This accesory is designed to use in ONE systems, it includes an audio preamp board and all the accessories needed to install it. The preamp board takes power from the ONE USB port. It includes a quality preamplifier with a gain of 40dB to convert the microphone level to an output line level compatible with 1Vrms inputs. The included circuit also converts the push to talk signal to a contact output, that is already prepared to be connected in the PRIO audio inputs 1 or 2.

With the ONE default configuration, if you press the PTT microphone, the audio will be routed to all zones. You can change the corresponding input settings in the PA Matrix screen menu. Additional advanced configurations could be applied to adapt the PTT to your needs. For example: Enable the use of the PTT when the system is in emergency (VA) state: Enter In advance settings by pressing ACK+OK for 3 seconds. Modify the variable called “DAM_PA_SRC_IN_VA_CUT_THRESHOLD” by selecting ID:2299 (FW v2.0.0.2). Change the value to 3 and input1 will be available to be used in VA state according to the system inputs priorities. A similar process must be done to allow the PTT if the AC power is not active (battery mode): Enter In advance settings by pressing ACK+OK for 3 seconds. Modify the variable called “DAM_PA_SRC_IN_BATT_CUT_THRESHOLD” by selecting ID:229A (FW v2.0.0.2).
