1. Open Router's Audio Switching tab and set the VOICE switching to CmCmA, Voice codec, SC1 on the
Radio 1 tab AND Radio 2 tab.
2. Go to Audio Mixer tab and confirm that the correct sound cards are selected
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 and
select the proper mixer channel for each function (microphone, line in, wave, etc.). Press both Get ID
buttons and confirm that the correct Sound Cards are selected.
NOTE: MK2R can use the same sound card for both SC1 (Voice) and SC2 (Digital) if is has separate
microphone and line inputs (e.g., a "three port" sound card).
3. Confirm that all the green lights below the sound card drop down boxes are lit. If not, double click on
them or open the specific mixer select (un-mute) the channels. When done, close both Volume Control
windows.
4. Set the REC MIC and TX MIC sliders to 70%, the TX VOICE MASTER sliders to 70% and WAVE sliders
to 80%.
5. Select a sampling rate on the REC MIC to enable the metering.
6. While speaking into the microphone, adjust the REC MIC slider until you see the last yellow light on
peaks. Do not allow the microphone signal to peak into the red.
7. Set the TX Mic slider to the same level as the REC MIC.
8. Select Radio 1 (press the Radio 1 Transmit Focus button)
9. Turn on VOX or press the MOX/transmit switch on the radio and speak into the microphone. Using the
R1 trimmer (see 7 on the previous page), set the same drive level as you set in step 12 on page 66. Do
not adjust the MIC GAIN knob on radio.
NOTE: To make fine adjustments, you can compare levels for the direct ("A") connection and through
the sound card ("Cm") by pressing the footswitch or hand mic PTT. When the radio is keyed by VOX or
MOX, the microphone audio is passing through the sound card. When the radio is keyed by the
footswitch or hand mic PTT, the microphone is connected directly to the radio.

increase or decrease the TX MIC slider as needed to balance the direct mic and sound card levels. Then
use the trimmer for fine adjustment.
