AUDIO MIXER TAB
NOTE: The Audio Mixer Tab is not present with Window Vista due to operating system limitations.
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 provides exceptional control over
the sound cards or codec with all level settings stored in the presets for each program (or configuration).
The Audio Mixer tab is divided to two parts, the left half is for control of SC1 or USB Voice Codec (VOICE
modes), the right half is for SC2 or USB Audio CODEC (DIGITAL modes).
You must select the names of the sound cards that are connected to MK2R or MK2R+ in the Audio Mixer.
For MK2R+ choose USB Voice CODEC at the left side and USB Audio CODEC at the right side. For MK2R
select the system name of the sound card connected to SC1 jacks (Voice) in the left side and the system
name of the sound card connected to the SC2 jacks (digital) in the right side.
MK2R+ selects the correct channels automatically, they must be selected manually for MK2R.
Channel assignments for SC1 (Voice):
REC MIC – Select Microphone channel
TX MIC – Select Microphone channel
TX VOICE – Select Wave channel
If these selections are not available, you may need to replace the sound card (or select another
sound card in your system). Most basic sound cards, including those in many laptops, provide the
resources needed for use at SC1.
Channel assignments for SC2 (Digital):
TX DIGITAL – Select Wave channel
RX RECORDING/DIGITAL – Select Line In
If these selections are not available, you may need to replace the sound card (or select another
sound card in your system).
