Functions
●
Microphone override function
This is a function where the audio level of LINE IN automatically lowers when the audio input of the microphone MIC1 or
microphone MIC2 is provided. The attenuation of the audio level is –12 dB.
When the audio input of the MIC1 or MIC2 is no longer provided, the volume of LINE IN automatically returns to the previous
level.
●
Paging mute function
This is a function where the audio outputs of the MIC1, MIC2, and mixing output of this unit are muted by closing the PAGE
MUTE terminal.
This function is specified with the control terminal or RS-232C. This function is set to OFF at default settings.
●
Tone function
This is a function where the operation sound output is provided from the MIX OUT connector when the volume button is
operated with the optional microphone, K-STD14. The operation sound is generated twice at the maximum and minimum
volumes.
The level of the operation sound can be set to HIGH or LOW with the DIP switch. The level is set to LOW at default settings.
This function is specified with the DIP switch. This function is set to OFF at default settings.
●
Microphone / line mixing function
This function is designed to assign the microphones, MIC1 and MIC2, to the mixing out, and two signals will be mixed with the
mixing out.
●
Remote volume function
This is a function where the volume of this unit cannot be adjusted with the volume button of the optional microphone, K-
STD14.
This function is used when external devices are controlled with the volume button through the use of the communication
control function of this unit.
This function is specified with the DIP switch. The volume can be controlled with the microphone at default settings.
●
Mixing output attenuator function
Setting the mixing output attenuator to ON provides attenuation in the mixing output by 10dB.
This function is useful when a device with high input sensitivity is connected.
This function is specified with the DIP switch. The output is set to –10dB at default settings.
■
About the feedback blocker
This is a function where the feedback loop generated when the microphone and speaker approach each other is reduced.
An integrated filter is automatically selected according to the generated audio frequency, and reduces the uncomfortable
feedback loop.
This function is specified with the DIP switch. This function is set to OFF at default settings.
Note: This function is simplified, and cannot fully remove the feedback loop. When the feedback loop is extremely large, this
function will work to mute all the audio outputs of this unit.
