Audio Mixer Tab - microHAM micro2R u2R User Manual

NOTE: The Audio Mixer Tab is not present in Windows Vista or 7 due to operating system limitations.
Windows Vista and 7 take exclusive control of the sound card and do not allow any application to
control the overall level or the select/mute switches for any audio "endpoint" (input or output).
The sound card configuration depends on the capability of your application software. Some software can
directly control the sound mixer, some can not. Router's Audio Mixer tab controls the sound cards and
stores all level settings in the presets for each program (or configuration).
You must select the name of the sound card connected to micro2R in the Audio Mixer.
NOTE: Because Windows can reassign sound cards while in use, Router may not invoke the proper mixer.
To check that the proper mixer has been assigned, click the Get ID button and confirm that the
proper sound card is selected. If the names do not match, restart Router.
REC MIC (software voice message recording level)
This control adjusts the level of microphone signal which will be used for recording
voice messages by the logging application. If channel is active, the green rectangle
light is on. If not, click on TX Mixer button and and select or unmute the Microphone
control.
Recording level: slider sets the level of the microphone input to the analog to
digital converter. Speak to the microphone and set slider to the position
where on peaks "stacked LED" display show RED on occasional peaks.
VU meter: this "stacked LED" displays shows the audio level into the analog to
digital controller. Please note, display operates only if a sample rate has
been selected.
Sample Rate: sets the sample rate used for the REC MIC level displays. It is best
to set the sample rate to a multiple of the sample rate (or "clock rate") of your applications.
