Port Properties¶
Specific interface ports have their own specific set of properties
2 wire interface port¶
2 Wire Mode¶
The Two wire mode pre-sets the gain presets for a specific 2 wire system
Option | Description |
---|---|
-18 dB | a -18 dB preset is used for nulling |
-15 dB | a -15 dB preset is used for nulling |
-12 dB | a -12 dB preset is used for nulling |
-9 dB | a -9 dB preset is used for nulling |
-6 dB | a -6 dB preset is used for nulling |
-3 dB | a -3 dB preset is used for nulling |
Disabled | Audio from and to the 2 wire is disabled |
RTS | a -5 dB preset is used for nulling |
Clearcomm | a -13 dB preset is used for nulling |
Tecpro | a -18 dB preset is used for nulling |
ASL | a -24 dB preset is used for nulling |
Auto-null¶
Auto-null enabled forces Nulling of the 2wire system on power-up of the device
Value | Description |
---|---|
Disabled | The device will use the last null setting when powered on |
Enabled | The Device will preform the Auto-null procedure when powered on. |
Two Wire Call mode¶
The call mode sets the way incoming and outgoing calls are handled
Option | Description |
---|---|
Disabled | calls are not send and received |
AC | AC calling is used for sending and receiving |
DC | DC calling is used for sending and receiving |
AC/DC | Both AC and DC are used for sending and receiving |
From 2-wire Adjust¶
Additional gain to adjust the level from the two-wire with a range of -20dB
to +20dB
From 2-wire Compressor¶
The compressor reduces the dynamic range off the input signal by reducing the louder parts of the signal. Making it less likely to be distorted. when enabled the release time of the compressor can be set.
Options
- Off
- Fast
- Medium
- Slow
From 2-wire Gate Threshold¶
The gate cuts of audio when below the set threshold. This is very use-full to keep the intercom system quiet and calm. A correctly set gate will only "open" the microphone when a user is talking. It will turn the mic off when the user stops talking.
Options
- Off
- -50dB
- -45dB
- -40dB
- -35dB
- -30dB
- -25dB
From 2-wire Gate Hold¶
The gate releases as soon as the audio is above the set threshold. the release time can be set with the gate hold. together with a correct set threshold the gate will nearly not be heard. this option is only available when the gate threshold is not OFF
Options
- Fast
- Medium
- Long
- Extra Long
To 2-wire Adjust¶
Additional gain to adjust the level to the two-wire with a range of -20dB
to +20dB
To 2-wire Limiter¶
The limiter will Limit the output to the 2-wire to the set amount
Range
- OFF (0dB)
- -24dB to -6dB
Radio interface port¶
Gain to adjust the level from the radio with range of -6dB
to +12dB
Radio Gain¶
Range
- OFF (0dB)
- -24dB to -6dB
Radio Compressor¶
The compressor reduces the dynamic range off the input signal by reducing the louder parts of the signal. Making it less likely to be distorted. when enabled the release time of the compressor can be set.
Options
- Off
- Fast
- Medium
- Slow
Radio Gate Threshold¶
The gate cuts of audio when below the set threshold. This is very use-full to keep the intercom system quiet and calm. A correctly set gate will only "open" the microphone when a user is talking. It will turn the mic off when the user stops talking.
Options
- Off
- -50dB
- -45dB
- -40dB
- -35dB
- -30dB
- -25dB
Radio Gate Hold¶
The gate releases as soon as the audio is above the set threshold. the release time can be set with the gate hold. together with a correct set threshold the gate will nearly not be heard. this option is only available when the gate threshold is not OFF
Options
- Fast
- Medium
- Long
- Extra Long
Radio Output Adjust¶
Additional gain to adjust the level to the radio with a range of -6dB
to +12dB
Radio Output Limiter¶
The limiter will Limit the output to the radio to the set amount
Range
- OFF (0dB)
- -24dB to -6dB
Radio TX mode¶
The TX mode sets the behaviour of the ptt relay, that will enable the radios transmission
Options
- disabled the ptt relay is never activated
- vox the ptt relay is activated if a talk is enabled and audio is received
- talk the ptt relay is activated as long as a talk is enabled
